  • How can I use a parent content control from a sub binding?

    - by MGSoto
    I have the following code currently: <DataTemplate DataType="{x:Type vm:SectionViewModel}"> <ScrollViewer> <ItemsControl ItemsSource="{Binding ViewModels}"> <Grid/> </ItemsControl> </ScrollViewer> </DataTemplate> <DataTemplate DataType="{x:Type vm:StringViewModel}"> <Label Name="Left" Grid.Row="0" Grid.Column="0" Content="{Binding Label}"/> <TextBox Name="Right" HorizontalAlignment="Stretch" Grid.Row="0" Grid.Column="1" Text="{Binding Value}"/> </DataTemplate> The ViewModels property bound to SectionViewModel ItemsControl is a list of StringViewModel. I want to insert each StringViewModel into some sort of content control in the ItemsControl. Originally I just had each StringViewModel to make its own Grid, but that left things unaligned. I'd like to insert these items into some sort of content control in ItemsControl, it doesn't necessarily have to be a grid, but it should be within the ItemsControl. How can I do this? I'm also following MVVM, using MVVM Light.

  • Editable, growable DataGrid that retains values on postback and updates underlying DataTable

    - by jlstrecker
    I'm trying to create an ASP.NET/C# page that allows the user to edit a table of data, add rows to it, and save the data back to the database. For the table of data, I'm using a DataGrid whose cells contain TextBoxes or CheckBoxes. I have a button for adding rows (which works) and a button for saving the data. However, I'm quite stuck on two things: The TextBoxes and CheckBoxes should retain their values on postback. So if the user edits a TextBox and clicks the button to add more rows, the edits should be retained when the page reloads. However, the edits should not be saved to the database at this point. When the user clicks the save button, or anytime before, the DataTable underlying the DataGrid needs to be updated with the values of the TextBoxes and CheckBoxes so that the DataTable can be sent to the database. I have a method that does this, but I can't figure out when to call it. Any help getting this to work, or suggestions of alternative user interfaces that would behave similarly, would be appreciated.

  • WPF Event Handler in Another Class

    - by Nathan Tornquist
    I have built a series of event handlers for some custom WPF controls. The event handles format the text displayed when the user enters or leaves a textbox based on the type of data contained (Phone number, zip code, monetary value, etc.) Right now I have all of the events locally in the C# code directly attached to the xaml. Because I have developed a could controls, this means that the logic is repeated a lot, and if I want to change the program-wide functionality I would have to make changes everywhere the event code is located. I am sure there is a way to put all of my event handlers in a single class. Can anyone help point me in the correct direction? I saw this article: Event Handler located in different class than MainWindow But I'm not sure if it directly relates to what I'm doing. I would rather make small changes to the existing logic that I have, as it works, then rewrite everything into commands. I would essentially like to something like this if possible: LostFocus="ExpandedTextBoxEvents.TextBox_LostFocus" It is easy enough to do something like this: private void TextBoxCurrencyGotFocus(object sender, RoutedEventArgs e) { ExpandedTextBoxEvents.TextBoxCurrencyGotFocus(sender, e); } private void TextBoxCurrencyLostFocus(object sender, RoutedEventArgs e) { ExpandedTextBoxEvents.TextBoxCurrencyLostFocus(sender, e); } But that is less elegant.

  • Keeping User-Input UITextVIew Content Constrained to Its Own Frame

    - by siglesias
    Trying to create a large textbox of fixed size. This problem is very similar to the 140 character constraint problem, but instead of stopping typing at 140 characters, I want to stop typing when the edge of the textView's frame is reached, instead of extending below into the abyss. Here is what I've got for the delegate method. Seems to always be off by a little bit. Any thoughts? - (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text { BOOL edgeBump = NO; CGSize constraint = textView.frame.size; CGSize size = [[textView.text stringByAppendingString:text] sizeWithFont:textView.font constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap]; CGFloat height = size.height; if (height > textView.frame.size.height) { edgeBump = YES; } if([text isEqualToString:@"\b"]){ return YES; } else if(edgeBump){ NSLog(@"EDGEBUMP!"); return NO; } return YES; } EDIT: As per Max's suggestion below, here is the code that works: - (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text { CGSize constraint = textView.frame.size; NSString *whatWasThereBefore = textView.text; textView.text = [textView.text stringByReplacingCharactersInRange:range withString:text]; if (textView.contentSize.height >= constraint.height) { textView.text = whatWasThereBefore; } return NO; }

  • Winforms App Not Displaying Graphical Elements in Design Mode

    - by Sev
    I wrote a bunch of code in the .cs file in c# for a winforms application. The application runs fine, and everything is in it's place. Something like this: using.. namespace Temp { public class Temp : Form { Button b1; TextBox t1; Temp() { b1.Text = "Some Text"; b1.Size = new Size(50,20); ... } void function1() { // stuff } static void Main() { Application.Run(new Temp()); } } } How can I modify my code (or fix it somehow) so that the design view displays the elements in their correct positions and view so that I can visually edit them instead of having to trial/error everything. Edit for Clarification My application runs fine. The problem is, that I didn't use designer to create the application and so in the designer view, the app is empty. But not empty when I run it, since everything is positioned programmatically in the .cs file. My question is, how can I fix this, so that the designer shows the objects correctly. There is no quick fix other than to redesign everything?

  • Inline form editing on client side

    - by bykasif
    I see some web sites use dynamic forms(I am not sure about how to call them!) to edit a group of data. For example: there is a group of data such as name, last name, city, country.etc. when user clicks on EDIT button, instead of doing postback, a form, consisisting of 2 textboxes + 2 comboboxes, dynamically opens to edit,And then when you click on Save button, edit form disappears, and all data updates.. Now, I know what happens over here is using Ajax for server calls and some javascript for dom manipulation.. I even found some jquery plugins for textbox editing.. However, I could not found anything for full implementation of form fields. Therefore I have implemented it on asp.net by jquery ajax calls and dom manipulation manually. here is my process: 1) when Edit button clicked: Make a ajax call to server to retrieve necessary formedit.aspx 2) it returns editable form fields with values assigned. 3) when Save button clicked: make ajax call to server to retrieve formupdateprocess.aspx page. it basically do the database updates and then return necessary DOM snipplet (...) to insert current page.. well it works but MY PROBLEM, is performance.. Result seems slower than samples I see in other sites.:(( IS there anything that I dont know? a better way to implement this??

  • How to use Transaction in Entity FrameWork?

    - by programmerist
    How to use Transaction in Entity FrameWork? i read some links on Stackoverflow : http://stackoverflow.com/questions/815586/entity-framework-using-transactions-or-savechangesfalse-and-acceptallchanges BUT; i have 3 table so i have 3 entities: CREATE TABLE Personel (PersonelID integer PRIMARY KEY identity not null, Ad varchar(30), Soyad varchar(30), Meslek varchar(100), DogumTarihi datetime, DogumYeri nvarchar(100), PirimToplami float); Go create TABLE Prim (PrimID integer PRIMARY KEY identity not null, PersonelID integer Foreign KEY references Personel(PersonelID), SatisTutari int, Prim float, SatisTarihi Datetime); Go CREATE TABLE Finans (ID integer PRIMARY KEY identity not null, Tutar float); Personel, Prim,Finans my tables. if you look Prim table you can see Prim value float value if i write a textbox not float value my transaction must run. using (TestEntities testCtx = new TestEntities()) { using (TransactionScope scope = new TransactionScope()) { // do someyihng... testCtx.Personel.SaveChanges(); // do someyihng... testCtx.Prim.SaveChanges(); // do someyihng... testCtx.Finans.SaveChanges(); scope .Complete(); success = true; } } How can i do that?

  • VB.net avoiding cross thread exception with extension method

    - by user574632
    Hello I am trying to implement a solution for updating form controls without using a delegate. I am attempting to use the 1st solution on this page: http://www.dreamincode.net/forums/blog/143/entry-2337-handling-the-dreaded-cross-thread-exception/ Imports System.ComponentModel Imports System.Runtime.CompilerServices Public Module MyInvoke <Extension()> _ Public Sub CustomInvoke(Of T As ISynchronizeInvoke)(ByVal control As T, ByVal toPerform As Action(Of T)) If control.InvokeRequired Then control.Invoke(toPerform, New Object() {control}) toPerform(control) End If End Sub End Module The site gives this as example of how to use: Label1.CustomInvoke(l => l.Text = "Hello World!") But i get 'l' is not declared error. As you can see im very new to VB or any OOP. I can get the second solution on that page to work (using delegates) but i have quite a few things to do in this thread and it seems like i would need to write a new delegate sub for each thing, which seems wasteful. What i need to do is select the 1st item from a combobox, update a textbox.text with the selected item, and pass the selected item to a function. Then wait for x seconds and start again, selecting the second item. I can get it to work in a single threaded application, but i need the interface to remain responsive. Any help greatly appreciated. EDIT: OK so changing the syntax worked for the example. However if i change it from Label1.CustomInvoke(Sub(l) l.text = "hello world!") (which worked just fine) to: Dim indexnumber As Integer = 0 ComboBox1.CustomInvoke(Sub(l) l.SelectedIndex = indexnumber) I get a cross threading error as though i didnt even use this method: Cross-thread operation not valid: Control 'ComboBox1' accessed from a thread other than the thread it was created on. So now im back to where i started? Any further help very much appreciated.

  • Including Data From DropDownList Into Gridview

    - by Mike Keller
    I feel a little embarassed posting two questions relating to the same problem, but the first one ended up answering a question that I believe is unrelated to the solution so I'm leaving it up and outlining what I'm trying to accomplish with the hopes that someone can help out a .Net noob. What I need to be able to do is create a field in my gridview that contains a link that passes two variables. One is pulled from within the gridviews datasource and the other needs to be pulled from a textbox control outside the gridview. From what I've read so far you cannot use a hyperlinkfield for this as the datanavigateurlfields cannot be set to pull from anything but the gridview's data source. What I attempted to do was create a template field where in the itemtemplate I called: <a href="example.aspx?e=<%# Eval(ExampleList.SelectedItem.Value) %>">Test</a> That comes back with an error like this: DataBinding: 'System.Data.DataRowView' does not contain a property with the value 'TestData' Any clues to make this happen would be appreciated, like I said I'm pretty new to .Net so please be gentle. I tried to do my homework before posting this.

  • optimized search using ajax and keypress

    - by ooo
    i have the following code as i want to search a database as a user is typing into a textbox. This code below works fine but it seems a little inefficient as if a user is typing really fast, i am potentially doing many more searches than necessary. So if a user is typing in "sailing" i am searching on "sail", "saili", "sailin", and "sailing" i wanted to see if there was a way to detect any particular time between keypresses so only search if user stops typing for 500 milliseconds or something like this. is there a best practices for something like this? $('#searchString').keypress(function(e) { if (e.keyCode == 13) { var url = '/Tracker/Search/' + $("#searchString").val(); $.get(url, function(data) { $('div#results').html(data); $('#results').show(); }); } else { var existingString = $("#searchString").val(); if (existingString.length > 2) { var url = '/Tracker/Search/' + existingString; $.get(url, function(data) { $('div#results').html(data); $('#results').show(); }); } }

  • Quality questionnaire php mysql graphipcs

    - by Marcelo
    Hi, i'm making a questionnaire about a service quality, its contains the options (poor, regular, good, very good). It's contains 6 questions (radio button) and a suggestion box (textbox). In the table of the database i created 6 rows for questions, 1 for suggestion and 1 for date (a friend of mine tole me to use this but i didn't get why). q1) I'm going to atribute a value form 1 to 4 to the radio buttons options, and i'd like to sum every answer for each question, and then divide by the numbers of user that answered that question and give the mean. how am i supposed to to that? I'd also like generate reports of the month, of the year. q2) not only about the questionnaire but for registration too. I need all the fields to be completed, no blank options, if he don't complete all of fields it'll not be submitted and there will be a warning message to the user. q3) about the field type, i'd like it to be the same class that is in the database, i'm having a "problem". Ex: Name(varchar) : 1234(int), in the field 'name' of the table of the database 1234 will be shown as name, and i don't want this, i want only the type that i declared in the construction of the table. q4) i'd also like to know if it's possible to create pizza graphics, about the percentage of each question, is this possible? q5) I'm using phpmyadmin and some of my id's are auto_increment, but 'cause of my tests they at a high number, i'd like to restart to 0 the ids number, is this possible? Thanks for the attention.

    Hi, I am beginner in JavaME. I'd like to make simple dicitionary. The source data is placed on "data.txt" file in "res" directory. The structure is like this: #apple=kind of fruit; #spinach=kind of vegetable; The flow is so simple. User enters word that he want to search in a text field, e.g "apple", system take the user input, read the "data.txt", search the matched word in it, take corresponding word, and display it to another textfield/textbox. I've managed to read whole "data.txt" using this code.. private String readDataText() { InputStream is = getClass().getResourceAsStream("data.txt"); try { StringBuffer sb = new StringBuffer(); int chr, i=0; while ((chr = is.read()) != -1) sb.append((char) chr); return sb.toString(); } catch (Exception e) { } return null; } but I still dont know how to split it, find the matched word with the user input and take corresponding word. Hope somebody willing to share his/her knowledge to help me.. Add to batosai_fk's Reputation

  • Wordpress Admin Panel Code Input

    - by Wes
    I've got a wordpress admin panel for one of my themes and one of the boxes has an input for some code to drive google adsense. when I put the code into the box and call it with my php tags the code comes out like this: <script type="\&quot;text/javascript\&quot;"><!-- google_ad_client = \"pub-9295546347478163\"; /* Leaderboard 5/17/2010 */ google_ad_slot = \"7593465074\"; google_ad_width = 728; google_ad_height = 90; //--> </script> <script type="\&quot;text/javascript\&quot;" src="%5C%22http://pagead2.googlesyndication.com/pagead/show_ads.js%5C%22"> </script> Which I assume is a feature to stop SQL injections. How can I call pure code form a box? This is how I currently have that textbox setup. array( "name" => "Code for Top ad", "desc" => "Enter the HTML that will drive the banner ad for the page header", "id" => $shortname."_headerAd", "type" => "textarea"), and then echo it out with this: <?php echo get_option('lifestyle_headerAd'); ?>

  • Advice on Minimizing Stored Procedure Parameters

    - by RPM1984
    Hi Guys, I have an ASP.NET MVC Web Application that interacts with a SQL Server 2008 database via Entity Framework 4.0. On a particular page, i call a stored procedure in order to pull back some results based on selections on the UI. Now, the UI has around 20 different input selections, ranging from a textbox, dropdown list, checkboxes, etc. Each of those inputs are "grouped" into logical sections. Example: Search box : "Foo" Checkbox A1: ticked, Checkbox A2: unticked Dropdown A: option 3 selected Checkbox B1: ticked, Checkbox B2: ticked, Checkbox B3: unticked So i need to call the SPROC like this: exec SearchPage_FindResults @SearchQuery = 'Foo', @IncludeA1 = 1, @IncludeA2 = 0, @DropDownSelection = 3, @IncludeB1 = 1, @IncludeB2 = 1, @IncludeB3 = 0 The UI is not too important to this question - just wanted to give some perspective. Essentially, i'm pulling back results for a search query, filtering these results based on a bunch of (optional) selections a user can filter on. Now, My questions/queries: What's the best way to pass these parameters to the stored procedure? Are there any tricks/new ways (e.g SQL Server 2008) to do this? Special "table" parameters/arrays - can we pass through User-Defined-Types? Keep in mind im using Entity Framework 4.0 - but could always use classic ADO.NET for this if required. What about XML? What are the serialization/de-serialization costs here? Is it worth it? How about a parameter for each logical section? Comma-seperated perhaps? Just thinking out loud. This page is particulary important from a user point of view, and needs to perform really well. The stored procedure is already heavy in logic, so i want to minimize the performance implications - so keep that in mind. With that said - what is the best approach here?

  • Can I get away with this or is it just too crude and unpractical ?

    - by The_AlienCoder
    I spent the whole of last night searching for a free AspNet web chat control that I could simply drag into my website. Well the search was in vain as I could not find a control that matched my needs i.e List of users, 1 to 1 chat, Ability to kick out users.. In the end I decided to create my own control from scractch. Although it works well on my machine Im concerned that It maybe a little crude and unpractical on a shared hosting enviroment. Basically this is what I did : Created an sql database that stores the chat messages. Wrote the stored procedures and and included a statement that clears old messages Then the 'crude' part : Dragged an update panel and timer control on my page Dragged a Repeater databound to the chat messages table inside the update panel Dragged another update panel and inside it put a textbox and a button Configured the timer control to tick every 5 seconds. ..and then I made it all work like this In the timer tick event I 'refreshed' the messages display by invoking Databind() on my repeater i.e protected void Timer1_Tick(object sender, EventArgs e) { MyRepeater.DataBind(); } Then in my send button click event protected void btnSend_Click(object sender, EventArgs e) { MyDataLayer.InsertMessage(Message, Sender, CurrTime); } Well It works well on my machine and Ive got the other functionalities(users list, kick out user..) to work by simply creating more tables. But like I said it seems a little crude to me. so I need a proffesional opinion. Should I run with this or try another Approach ?

  • How to check user input for correct formatting

    - by Arcadian
    This is what i've come up with so far private void CheckFormatting() { StringReader objReaderf = new StringReader(txtInput.Text); List<String> formatTextList = new List<String>(); do { formatTextList.Add(objReaderf.ReadLine()); } while (objReaderf.Peek() != -1); objReaderf.Close(); for (int i = 0; i < formatTextList.Count; i++) { } } What it is designed to do is check that the user has entered their information in this format Gxx:xx:xx:xx JGxx where "x" can be any integer. As you can see the user inputs their data into a multi-line textbox. i then take that data and enter it into a list. the next part is where i'm stuck. i create a for loop to go through the list line by line, but i guess i will also need to go through each line character by character. How do i do this? or is there a faster way of doing it? thanks in advance

  • Select hidden input from within next td [jQuery]

    - by Fverswijver
    I have a table layed out like this: <td> somename </td> <td class="hoverable value" > somevalue </td> <td class="changed"> </td> <td class="original value"> <input type="hidden" value="somevalue" /> </td> And what I'm trying to do is, I hover over the hoverable td which turns it into a textbox. Once I hover out I want to check the hidden field for it's original value and put an image in changed if the 2 are different from each other. I already have this: $(document).ready( function() { var newHTML = ''; $('table td.hoverable').hover( function () { var oldHTML = $(this).html().trim(); $(this).html('<input type=\'text\' value=\'' + oldHTML + '\' size=\'' + ((oldHTML).length + 2) +'\' />'); }, function() { newHTML = $('input', this).val(); var oldHTML = $(this).next('td.original').children('hidden').val(); if(newHTML != oldHTML) { $(this).next('td.changed').html('Changed'); } $(this).html(newHTML); }) }); but it doesn't work. What fails apparently is grabbing the value of the hidden field, and I've tried selecting it in several different ways but just can't get to it. Any ideas or tips are gratefully appreciated ;)

  • Tkinter, Python: How do I save text entered in the Entry widget? How do I move a label?

    - by user3692825
    I am a newbie at programming and my program is not stellar but hopefully it's ok because I have only been using it for a couple days now. I am having trouble in my class "Recipie". In this class I am having trouble saving the text in my Entry widget. I know to use the .get() option but when I try to print it, it doesn't (whether it is within that defined method or not). So that is my main concern. I want it to save the text entered as a string when I press the button: b. My other minor question is, how can I move the label. When I have tried I have used the height and width options, but that just expands the label. I want to move the text to create a title above my Entry boxes. Is label the right widget to use or would it be easier to use a message box widget? So it would look like, for example (but like 8 pixels down and 20 to the right): ingredients textbox button labeled as: add an ingredient And I am not sure the option .pack(side="...") or .place(anchor="...") are the right options to use for my buttons or entry boxes or labels. Any help is greatly appreciated!!! And if you could add comments to your code explaining what you did, that would be so helpful. Thank you!!! import Tkinter class Recipie(Tkinter.Tk): def __init__(self): Tkinter.Tk.__init__(self) self.title("New Recipie") self.geometry("500x500") def name(self): name = Tkinter.Label(self, text="Title:", width=39) name.place(anchor="nw") insert_name = Tkinter.Entry(self) insert_name.pack() insert_name.focus_set() def ingredients(self): e = Tkinter.Entry(self) e.pack() e.focus_set() def addingredient(self): but = Tkinter.Button(self, text="Add Ingredients", width=15, command=self.ingredients) but.pack(side="bottom") def procedure(self): txt = Tkinter.Label(self, text="List the Steps:") txt.place(anchor="n") p = Tkinter.Entry(self) p.place(anchor="nw") p.focus_set() def savebutton(self): print insert_name.get() print e.get() print p.get() b = Tkinter.Button(self, text="Save Recipie", width=15, command=savebutton) top = Recipie() top.mainloop()

  • [java] tcp socket communication [send and recieve help]

    - by raven
    hello, I am creating a Chat in java. I have a method (onMouseRelease) inside an object that creates a tcp server and waits for a socket ServerSocket server = new ServerSocket(port); Socket channel = server.accept(); now I want to make a thread that will loop and read data from the socket, so that once the user on the other side sent me a string, I will extract the data from the socket [or is it called packet? sry I am new to this], and update a textbox to add the additional string from the socket [or packet?]. I have no idea how to READ (extract) the information from the scoket [/packet] and then update it into a JTextArea which is called userOutput. And how to Send a string to the other client, so that it will also could read the new data and update its JTextArea. (from what I know, for a 2 sided tcp communication you need one computer to host a server and the other to connect [as a client] and once the connection is set the client can also recieve new information from the socket. Is that true? and please tell me how ) Any help appreciated !! I know this is abit long but I have searched allot and didn't understand [I saw something like printwriter but failed to understand].

  • How to submit to the server with JQuery.UI Dialog and ASP.Net?

    - by Paul
    Hi, I'm looking for a way to submit information captured in a JQuery Dialog to the server in ASP.Net. I originally thought it would work with a 'hidden' asp button, but the click doesn't seem to be submitting the form. Here's the code I have so far: <script type="text/javascript"> jQuery(document).ready(function() { var dlg = jQuery("#dialog").dialog({ bgiframe: true, autoOpen: false, height: 150, width: 300, modal: true, buttons: { "Add": function() { var btn = document.getElementById("<%=btnAdd.ClientID %>"); if (btn) btn.click(); $(this).dialog("close"); } } }); $("#dialog").parent().appendTo("#dialog_target"); }); </script> <div id="hidden" style="visibility:hidden" > <!-- Hidden button that actually triggers server add --> <asp:Button ID="btnAdd" runat="server" style="display:none" OnClick="btnAdd_Click" /> <!-- Hidden Delete Dialog --> <div id="dialog" title="New Additional Skill"> <label>Additional Skill Name:</label> <asp:TextBox ID="_txtNewSkillName" runat="server" /> </div> Any pointers?

  • Why doesn't my dataset.AcceptChanges update some new rows i've added? C#

    - by user280139
    I have a dataset in a datagrid with some data in it. Recently I've been asked to add some data to that dataset along with some controls to save the data from. I've added a few textboxes, 1 combobox and 3 textboxes that function as viewing of some datetimepickers that I have to use for dates. I've chosen to use textboxes in combination with datetimepicker because I also need to get and set the value NULL to the database. The problem is that when i call dataset.AcceptChanges() on that dataset that is binded using databinding to those controls it doesn't update the data that's contained in those three textboxes and the combobox. All the new stuff i've added works just fine. txtDataAcordare.DataBindings.Clear(); txtDataAcordare.DataBindings.Add("Text",dtPersonal,"d_DataAcordare"); txtDataInceput.DataBindings.Clear(); txtDataInceput.DataBindings.Add("Text", dtPersonal, "d_DataInceput"); txtDataSfarsit.DataBindings.Clear(); txtDataSfarsit.DataBindings.Add("Text", dtPersonal, "d_DataSfarsit"); this is the code i use to add the databinding. I am then using the datetime picker event CloseUp() to add the date into the textbox: txtDataAcordare.Text = dtpDataAcordare.Text; txtDataAcordare.Visible = true; txtDataAcordare.BringToFront(); After all my fields are completed i call: dtPersonal.AcceptChanges(); and these three textboxes don't get saved! Help, please! dtpDataAcordare.SendToBack();

  • Continuously updating chat messages

    - by Daniel
    I'm creating a very simple chat application. It has an ASP.NET web page as front-end and a WCF service as back-end for storing the messages to a database. Everything works great except one thing; when Browser A enters a chat message I want Browser B to see the message as soon as possible (yeah, I know, that's the purpose of a chat). What I've done so far is to setup a trigger within the UpdatePanel, like this: <Triggers> <asp:AsyncPostBackTrigger ControlID="chatTimer" EventName="Tick" /> </Triggers> which uses a timer: <asp:Timer ID="chatTimer" runat="server" OnTick="chatTimer_Tick" Interval="1000" /> Is this the best approach or is there a better, yet simple, way to accomplish updating of messages. One drawback with this solution is that the textbox used to enter chat messages loses focus every time the Tick event runs. Any piece of feedback or advice regarding updating of messages is appreciated. Thank you!
