  • Before data is entered, is there a way to make a grouped table graphic placeholder?

    - by Matt Winters
    I have a grouped table with 3 sections, each section with a title. The 1st and 3rd sections always have only 1 row of information so before any user data is entered, I just put some words like "Enter Data Here..." as placeholder text. This text is edited (replaced) by the user with their own actual data. No problem. The 2nd section however will contain several rows of information entered by user and I'd prefer not to enter placeholder data in row 0, having the user Edit the first row of data then Add subsequent rows. If the numberOfRowsInSection is set to 0, the title for the 3rd section comes close to the title for the 2nd section and it looks ugly. The best that I could come with, and I don't know to do it, is to have a fake graphic placeholder on the striped background (between the 2nd and third titles) that looks like a single row in the 2nd section, put "Enter Data Here..." text in the graphic, and then the first row of actual data entered and all subsequent rows will cover it up. Can anyone tell me how to do this or offer a better suggestion. Thanks.

  • String Builder Class in asp.net

    - by Indranil Mutsuddy
    Hiya, Suppose I want to display text retrieved from data base and I want to display the text applying color, font style etc. Is that possible?..Below is a sample code which i 've done recently. SqlDataReader myreader; myreader = cmmd.ExecuteReader(); StringBuilder sb = new StringBuilder(); sb.Append("<b>Vaccine</b>&nbsp;&nbsp;&nbsp;<b> Vaccination Date</b>&nbsp;&nbsp;&nbsp;<b> Vaccination Due Date</b>&nbsp;&nbsp;&nbsp;<b> Incomplete Vaccination </b>&nbsp;&nbsp;&nbsp;<b>Dose No.</b>&nbsp;&nbsp;&nbsp;<b> Remarks </b><br/><br/>"); while (myreader.Read()) { sb.Append(myreader["VaccineID"]); sb.Append("&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"); sb.Append(myreader["DateOFVaccine"]); sb.Append("&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"); sb.Append(myreader["NextVaccinationDueDate"]); sb.Append("&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"); sb.Append(myreader["AnyIncompleteImmunization"]); sb.Append("&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"); sb.Append(myreader["DoseNumber"]); sb.Append("&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"); sb.Append(myreader["Remark1"]); sb.Append("<br/>"); } lblDisplayDetails.Text = sb.ToString(); myreader.Close(); Thank You

  • Parameterized Queries /Without/ using queries.

    - by Aren B
    I've got a bit of a poor situation here. I'm stuck working with commerce server, which doesn't do a whole lot of sanitization/parameterization. I'm trying to build up my queries to prevent SQL Injection, however some things like the searches / where clause on the search object need to be built up, and there's no parameterized interface. Basically, I cannot parameterize, however I was hoping to be able to use the same engine to BUILD my query text if possible. Is there a way to do this, aside from writing my own parameterizing engine which will probably still not be as good as parameterized queries? Update: Example The where clause has to be built up as a sql query where clause essentially: CatalogSearch search = /// Create Search object from commerce server search.WhereClause = string.Format("[cy_list_price] > {0} AND [Hide] is not NULL AND [DateOfIntroduction] BETWEEN '{1}' AND '{2}'", 12.99m, DateTime.Now.AddDays(-2), DateTime.Now); *Above Example is how you refine the search, however we've done some testing, this string is NOT SANITIZED. This is where my problem lies, because any of those inputs in the .Format could be user input, and while i can clean up my input from text-boxes easily, I'm going to miss edge cases, it's just the nature of things. I do not have the option here to use a parameterized query because Commerce Server has some insane backwards logic in how it handles the extensible set of fields (schema) & the free-text search words are pre-compiled somewhere. This means I cannot go directly to the sql tables What i'd /love/ to see is something along the lines of: SqlCommand cmd = new SqlCommand("[cy_list_price] > @MinPrice AND [DateOfIntroduction] BETWEEN @StartDate AND @EndDate"); cmd.Parameters.AddWithValue("@MinPrice", 12.99m); cmd.Parameters.AddWithValue("@StartDate", DateTime.Now.AddDays(-2)); cmd.Parameters.AddWithValue("@EndDate", DateTime.Now); CatalogSearch search = /// constructor search.WhereClause = cmd.ToSqlString();

  • VB.NET invalid cast exception

    - by user127147
    Hi there, I have a simple application to store address details and edit them. I have been away from VB for a few years now and need to refreash my knowledge while working to a tight deadline. I have a general Sub responsible for displaying a form where user can add contact details (by pressing button add) and edit them (by pressing button edit). This sub is stored in a class Contact. The way it is supposed to work is that there is a list with all the contacts and when new contact is added a new entry is displayed. If user wants to edit given entry he or she selects it and presses edit button Public Sub Display() Dim C As New Contact C.Cont = InputBox("Enter a title for this contact.") C.Fname = frmAddCont.txtFName.Text C.Surname = frmAddCont.txtSName.Text C.Address = frmAddCont.txtAddress.Text frmStart.lstContact.Items.Add(C.Cont.ToString) End Sub I call it from the form responsible for adding new contacts by Dim C As New Contact C.Display() and it works just fine. However when I try to do something similar using the edit button I get errors - "Unable to cast object of type 'System.String' to type 'AddressBook.Contact'." Dim C As Contact If lstContact.SelectedItem IsNot Nothing Then C = lstContact.SelectedItem() C.Display() End If I think it may be something simple however I wasn't able to fix it and given short time I have I decided to ask for help here. Thank you

  • template engine implementation

    - by qwerty
    I am currently building this small template engine. It takes a string containing the template in parameter, and a dictionary of "tags,values" to fill in the template. In the engine, I have no idea of the tags that will be in the template and the ones that won't. I am currently iterating (foreach) on the dictionnary, parsing my string that I have put in a string builder, and replacing the tags in the template by their corresponding value. Is there a more efficient/convenient way of doing this? I know the main drawback here is that the stringbuilder is parsed everytime entirely for each tag, which is quite bad... (I am also checking, though not included in the sample, after the process that my template does not contain any tag anymore. They are all formated in the same way: @@tag@@) //Dictionary<string, string> tagsValueCorrespondence; //string template; StringBuilder outputBuilder = new StringBuilder(template); foreach (string tag in tagsValueCorrespondence.Keys) { outputBuilder.Replace(tag, tagsValueCorrespondence[tag]); } template = outputBuilder.ToString(); Responses: @Marc: string template = "Some @@foobar@@ text in a @@bar@@ template"; StringDictionary data = new StringDictionary(); data.Add("foo", "value1"); data.Add("bar", "value2"); data.Add("foo2bar", "value3"); Output: "Some text in a value2 template" instead of: "Some @@foobar@@ text in a value2 template"

  • How do I compress a Json result from ASP.NET MVC with IIS 7.5

    - by Gareth Saul
    I'm having difficulty making IIS 7 correctly compress a Json result from ASP.NET MVC. I've enabled static and dynamic compression in IIS. I can verify with Fiddler that normal text/html and similar records are compressed. Viewing the request, the accept-encoding gzip header is present. The response has the mimetype "application/json", but is not compressed. I've identified that the issue appears to relate to the MimeType. When I include mimeType="*/*", I can see that the response is correctly gzipped. How can I get IIS to compress WITHOUT using a wildcard mimeType? I assume that this issue has something to do with the way that ASP.NET MVC generates content type headers. The CPU usage is well below the dynamic throttling threshold. When I examine the trace logs from IIS, I can see that it fails to compress due to not finding a matching mime type. <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files" noCompressionForProxies="false"> <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" /> <dynamicTypes> <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/x-javascript" enabled="true" /> <add mimeType="application/json" enabled="true" /> </dynamicTypes> <staticTypes> <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/x-javascript" enabled="true" /> <add mimeType="application/atom+xml" enabled="true" /> <add mimeType="application/xaml+xml" enabled="true" /> <add mimeType="application/json" enabled="true" /> </staticTypes> </httpCompression>

    Hi, Im using FCK Editor control instead a textarea element. I installed it without problems. But when i want to validate it with a Custom validator of ASP.Net 2.0, im not getting the result expected. These lines are the code that i have: <textarea style="width:30px;height:20px;" class="ckeditor" id="txtdescription" runat="server" name="txtdescription" cols="5" rows="10"></textarea> <asp:CustomValidator id="descval" runat="server" ControlToValidate="txtdescription" EnableClientScript="true" Enabled="true" ValidateEmptyText="true" Display="Dynamic" ClientValidationFunction="ValidateTextDesc" Text="*" ErrorMessage="*"/> <asp:Button ID="buttonadd" runat="server" Text="Add text" OnClick="buttonadd_Click" /> And my javascript code that executes the CustomValidator client function is: function ValidateTextDesc(source, args) { var descriptiontext = document.getElementById("txtdescription"); if ((descriptiontext.value.indexOf("<script") != -1) || (descriptiontext.value.length==0)) { args.IsValid=false; } else { args.IsValid = true; } return args.IsValid; } My problem is that i have to click twice my submit button to execute this Client function: Do you know why this issue is happening? Thanks in advance. Regards. Josema.

  • Drag-n-Drop on contentEditable elements

    - by Raybiez
    There are numerous WYSIWYG editors available on the internet, but I'm yet to find one that implements some form of drag-n-drop implementation. It is easy to create one's own editor, but I want to the user to be able to drag elements (ie. tokens) from outside the editable area and have them drop it at a location of their choice inside the editable area. It is easy to inject html at a specific location of an editable element, but how do one determine where the caret should be when the user is dragging a DIV over some element in the editable area. To better illustrate what I'm trying to explain, see the following scenario. The editable area (either an IFRAME in edit mode or a DIV with its contentEditable attribute set to true) already contains the following text: "Dear , please take note of ...." The user now drags an element representing some token from a list of elements, over the editable area, moving the cursor over the text until the caret appear just before the comma (,) in the text as shown above. When the user releases the mouse button at that location, HTML will be injected which could result in something like this: "Dear {UserFirstName}, please take note of ...". I do not know if anyone has ever done anything similar to this, or at least know of how one would go about doing this using JavaScript. Any help will be greatly appreciated.

  • Set predefine form value (webbrowser control)

    - by Khou
    Hi I want to load my windows form: web browser thats using the webbrowser control, It would load a web page, and load my defination and search for elements that has been define, it will then assign the default values and these values can not be changed by the end user. Example If my application finds "FirstName" it would always assign the value "John" If my application finds "LastName" it would always assign the value "Smith" (these values should not be changed by the end user). Here's how to do it in HTML/JAVASCRIPT, but how do i do this in a windows form? HTML <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <html> <head> <title>page title</title> <script script type="text/javascript" src="demo1.js"></script> </head> <body onload="def(document.someform, 'name', 'my default name value');"> <h2 style="color: #8e9182">test form title</h2> <form name="someform" id="someform_frm" action="#"> <table cellspacing="1"> <tr><td><label for="name">NameX: </label></td><td><input type="text" size="30" maxlength="155" name="name" onchange="def(document.someform, 'name', 'my default name value');"></td></tr> <tr><td><label for="name2">NameY: </label></td><td><input type="text" size="30" maxlength="155" name="name2"></td></tr> <tr><td colspan="2"><input type="button" name="submit" value="Submit" onclick="showFormData(this.form);" ></td></table> </form> </body> </html> JAVASCRIPT function def(oForm, element_name, def_txt) { oForm.elements[element_name].value = def_txt; }

  • Binding Data to a TextBlock using Domain Data Source

    - by TFisher
    I have a map with hotspots for each state (done in Expression Blend). I capture each MouseEnter of the state (1 thru 50). I pass that into my Domain Data Source: Dim activebox As Path = TryCast(sender, Path) activebox.Fill = mouseOverColor Dim StateID As Integer = CInt(Right(activebox.Name, 2)) Dim _StateContext As New StateContext myDataGrid.ItemsSource = _StateContext.States _StateContext.Load(_StateContext.GetStateByStateIDQuery(StateID.Text)) The above works fine for a datagrid, listbox and even a dataform. But I created a popup with a stackpanel that has textblocks. popupStatesBox.DataContext = ?????????????? popupStatesBox.IsOpen = True 'popup does open but has no data -- popupStatesBox.xaml <Popup x:Name="popupStatsBox" Margin="8,35,0,8" DataContext="{Binding}" IsOpen="false" Width="268" HorizontalAlignment="Left"> <StackPanel x:Name="Layout" Background="Black"> <TextBlock x:Name="tbState" Text="{Binding StateName /> <TextBlock x:Name="tbAbbrev" Text="{Binding Abbreviation}" /> </StackPanel> </Popup> How do I get the textblocks to display the values from the _StateContext. StackPanel has DataContext but no ItemsSource. What am I missing?

  • How to pass PHP variable as FlashVars via SWFObject

    - by Matt
    I am trying to take a PHP variable and pass it along to Flash via Flash vars. My end goal is to pass a string formatted as XML to Flash, but because I'm struggling I've stripped everything down to the basics. I'm just trying to pass a simple PHP string variable to Flash via FlashVars with SWFObject but something isn't right. The page won't load when I try to pass the variable inside of php tags, but it will load if I just pass a hard coded string. The basic structure of my page is that I have some PHP declared at the top like so: PHP <?php $test = "WTF"; ?> Some HTML (excluded here for simplicity sake) and then the JavaScript SWFObject Embed within my HTML: <script type="text/javascript" src="js/swfobject2.js"></script> <script type="text/javascript"> // <![CDATA[ var swfURL = "swfs/Init-Flash-PHP.swf"; var flashvars = {}; flashvars.theXML = <?php print $test ?>; var params = {}; //params.menu = "false"; params.scale = "showAll"; params.bgcolor = "#000000"; params.salign = "TL"; //params.wmode = "transparent"; params.allowFullScreen = "true"; params.allowScriptAccess = "always"; var attributes = {}; attributes.id = "container"; attributes.name = "container"; swfobject.embedSWF(swfURL, "container", '100%', '100%', "9.0.246", "elements/swfs/expressinstall.swf", flashvars, params, attributes); // ]]> </script> And the bare essentials of the ActionScript 3 Code: _paramObj = LoaderInfo(stage.loaderInfo).parameters; theText_txt.text = _paramObj['theXML']; How do I pass a PHP variable using SWFObject and FlashVars? Thanks.

  • JQuery traverse DOM and extract node value

    - by Alex
    I have the following DOM: <div class="qtip qtip-light qtip-active"> <div class="qtip-wrapper"> <div class="qtip-borderTop"></div> <div class="qtip-contentWrapper"> <div class="qtip-title"> <div class="qtip-button"></div> **Text I need to extract** </div> <div class="qtip-content"> <div class="tooltip"> <div class="button-container"> <script type="text/javascript"> var link = null; var link = $('.qtip-active > .qtip-title').val(); $('.qtip-active > #button-container').append('<a href=\"mailto:' + link + '\">' + link + '</a>'); </script> </div> </div> </div> </div> <div class="qtip-borderBottom"></div> </div> </div> But the variable link is always undefined when I would expect it to return the text the node specified.

  • How can a silverlight app download and play an mp3 file from a URL?

    - by Edward Tanguay
    I have a small Silverlight app which downloads all of the images and text it needs from a URL, like this: if (dataItem.Kind == DataItemKind.BitmapImage) { WebClient webClientBitmapImageLoader = new WebClient(); webClientBitmapImageLoader.OpenReadCompleted += new OpenReadCompletedEventHandler(webClientBitmapImageLoader_OpenReadCompleted); webClientBitmapImageLoader.OpenReadAsync(new Uri(dataItem.SourceUri, UriKind.Absolute), dataItem); } else if (dataItem.Kind == DataItemKind.TextFile) { WebClient webClientTextFileLoader = new WebClient(); webClientTextFileLoader.DownloadStringCompleted += new DownloadStringCompletedEventHandler(webClientTextFileLoader_DownloadStringCompleted); webClientTextFileLoader.DownloadStringAsync(new Uri(dataItem.SourceUri, UriKind.Absolute), dataItem); } and: void webClientBitmapImageLoader_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e) { BitmapImage bitmapImage = new BitmapImage(); bitmapImage.SetSource(e.Result); DataItem dataItem = e.UserState as DataItem; CompleteItemLoadedProcess(dataItem, bitmapImage); } void webClientTextFileLoader_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e) { DataItem dataItem = e.UserState as DataItem; string textFileContent = e.Result.ForceWindowLineBreaks(); CompleteItemLoadedProcess(dataItem, textFileContent); } Each of the images and text files are then put in a dictionary so that the application has access to them at any time. This works well. Now I want to do the same with mp3 files, but all information I find on the web about playing mp3 files in Silverlight shows how to embed them in the .xap file, which I don't want to do since I wouldn't be able to download them dynamically as I do above. How can I download and play mp3 files in Silverlight like I download and show images and text?

  • Equivalent of Flex DataBinding using Pure Actionscript

    - by Joshua
    What is the ActionScript equivalent of this? <mx:Label text="Hello {MyVar} World!"/> In ActionScript it would need it to look something like this: var StringToBind="Hello {MyVar} World!"; // I've Written It This Way Because I Don't Know The Exact Text To Be Bound At Design Time. [Bindable] var MyVar:String='Flex'; var Lab:Label=new Label(); Lab.text=??? ... SomeContainer.addChild(Lab); How can I accomplish this kind of "Dynamic" binding... Where I don't know the value of "StringToBind" until runtime? For the purposes of this question we can assume that I do know that any variable mentioned in "StringToBind", is guaranteed to exist at runtime. I already realize there are much more straightforward ways to accomplish this exact thing STATICALLY, and using only Flex. It's important for my project though that I understand how this could be accomplished using purely ActionScript.

  • Designing a fluid Javascript interface to hide callback asynchrony

    - by Anurag
    How would I design an API to hide the asynchronous nature of AJAX and HTTP requests, or basically delay it to provide a fluid interface. To show an example from Twitter's new Anywhere API: // get @ded's first 20 statuses, filter only the tweets that // mention photography, and render each into an HTML element T.User.find('ded').timeline().first(20).filter(filterer).each(function(status) { $('div#tweets').append('<p>' + status.text + '</p>'); }); function filterer(status) { return status.text.match(/photography/); } vs this (asynchronous nature of each call is clearly visible) T.User.find('ded', function(user) { user.timeline(function(statuses) { statuses.first(20).filter(filterer).each(function(status) { $('div#tweets').append('<p>' + status.text + '</p>'); }); }); }); It finds the user, gets their tweet timeline, filters only the first 20 tweets, applies a custom filter, and ultimately uses the callback function to process each tweet. I am guessing that a well designed API like this should work like a query builder (think ORMs) where each function call builds the query (HTTP URL in this case), until it hits a looping function such as each/map/etc., the HTTP call is made and the passed in function becomes the callback. An easy development route would be to make each AJAX call synchronous, but that's probably not the best solution. I am interested in figuring out a way to make it asynchronous, and still hide the asynchronous nature of AJAX.

  • javascript RegEx hashtag matching #foo and #foo-fåäö but not http://this.is/no#hashtag

    Currently we're using javascript new RegExp('#[^,#=!\s][^,#=!\s]*') (see [1]) and it mostly works, except that it also matches URLs with anchors like http://this.is/no#hashtag and also we'd rather avoid matching foo#bar Some attempts have been made with look-ahead but it doesn't seem to work, or that I just don't get it. With the below source text: #public #writable #kommentarer-till-beta -- all these should be matched Verkligen #bra jobbat! T ex #kommentarer till #artiklar och #blogginlägg, kool. -- mixed within text http://this.is/no#hashtag -- problem xxy#bar -- We'd prefer not matching this one, and... #foo=bar =foo#bar -- we probably shouldn't match any of those either. #foo,bar #foo;bar #foo-bar #foo:bar -- We're flexible on whether these get matched in part or in full . We'd like to get below output: (showing $ instead of <a class=tag href=.....>...</a> for readability reasons) $ $ $ -- all these should be matched Verkligen $ jobbat! T ex $ till $ och $, kool. -- mixed within text http://this.is/no$ -- problem xxy$ -- We'd prefer not matching this one, and... $=bar =foo$ -- we probably shouldn't match any of those either. $,bar $ $ $ -- We're flexible on whether these get matched in part or in full [1] http://github.com/ether/pad/blob/master/etherpad/src/plugins/twitterStyleTags/hooks.js

  • searching article for names in the database before submitting article to the database

    - by zurna
    I want to create a function that will search through a text, find names those match with existing names in the database and add links to those names before submitting the article to the database. i.e. text: Chelsea are making a change now as goalscorer Nicolas Anelka is replaced by in-form Florent Malouda who can do no wrong lately. Nicolas Anelka exists in the database in the Players table with ID column equals to 1. I want text to be converted to Chelsea are making a change now as goalscorer Nicolas Anelka is replaced by in-form Florent Malouda who can do no wrong lately. I know my code is logically wrong but I could build the correct logic. Function PlayerStats (ArticleDesc) If IsNull(ArticleDesc) Then Exit Function SQL = "SELECT PlayerID, PlayerName" SQL = SQL & " FROM Players" SQL = SQL & " WHERE PlayerID = "& &"" Set objTeam = objConn.Execute(SQL) ArticleDesc = Replace(ArticleDesc, "&", "&amp;") PlayerStats = ArticleDesc End Function

  • jquery wait till large document is loaded

    - by Martijn
    In my web application I call a document can be huge. This document is loaded into an iframe. I have a title, buttons and the text which all depends on this document. The text is from the large document and is displayed in the iframe. I'd like to show an animated gif while the document is loading on 3 places (1: document title, 2: document buttons, 3: document text, the iframe) I've tried the onload event on the Iframe, but this doesn't give the me the desired effect. Here's my code that loads the document: function loadDocument(id, doc) { $("#DocumentContent").show(); $("#ButtonBox").show(); // Clear dynamic menu items $("#DynamicMenuContent").html(""); $("#PageContent").html(""); // Load document in frame $("#iframeDocument").attr("src", 'ViewDoc.aspx?id=' + id + '&doc=' + doc + ''); // $("#iframeDocument").attr("src", "Graphics/loader.gif"); // Load menu items $.ajax({ url: "ShowButtons.aspx?id=" + id + "&doc=" + doc, success: function(data) { $("#DynamicMenuContent").html(data) }, error: function(xhr, err, e) { alert("error: " + err) } }); // Set document title $("#documentTitle").load("GetDocumentInfo.aspx?p=title"); } My questions, how can I display a loader gif while the document is loaded? And remove the gif when the document is ready?

  • Scaling Literate Programming?

    - by Tetha
    Greetings. I have been looking at Literate Programming a bit now, and I do like the idea behind it: you basically write a little paper about your code and write down as much of the design decisions, the code probably surrounding the module, the inner workins of the module, assumptions and conclusions resulting from the design decisions, potential extension, all this can be written down in a nice way using tex. Granted, the first point: it is documentation. It must be kept up-to-date, but that should not be that bad, because your change should have a justification and you can write that down. However, how does Literate Programming Scale to a larger degree? Overall, Literate Programming is still just text. Very human readable text, of course, but still text, and thus, it is hard to follow large systems. For example, I reworked large parts of my compiler to use and some magic to chain compile steps together, because some "x.register_follower(y); y.register_follower(z); y.register_follower(a);..." got really unwieldy, and changing that to x y z a made it a bit better, even though this is at its breaking point, too. So, how does Literate Programming scale to larger systems? Does anyone try to do that? My thought would be to use LP to specify components that communicate with each other using event streams and chain all of these together using a subset of graphviz. This would be a fairly natural extension to LP, as you can extract a documentation -- a dataflow diagram -- from the net and also generate code from it really well. What do you think of it? -- Tetha.

  • Conditional required field validation in an ASP.net ListView

    - by Jim Dagg
    I'm having a heck of a time trying to figure out how to implement validation in a ListView. The goal is to require the user to enter text in the comments TextBox, but only if the CheckBox is checked. Downside is that these controls are in the EditTemplate of a ListView. Below is a snippet of the relevant code portion of the EditTemplate: <tr style="background-color: #00CCCC; color: #000000"> <td> Assume Risk? <asp:CheckBox ID="chkWaive" runat="server" Checked='<%# Bind("Waive") %>' /> </td> <td colspan="5"> <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="Comments required" ControlToValidate="txtComments" /> <asp:TextBox Width="95%" ID="txtComments" runat="server" Text='<%# Eval("Comment") %>'></asp:TextBox> </td> <td> <asp:Button ID="btnSave" runat="server" Text="Save" CommandName="Update" Width="100px" /> </td> </tr> Is there a way to do conditional validation using this method? If not, is there a way I could validate manually in the ItemUpdating event of the Listview, or somewhere else, and on a failure, alert the user of the error via a label or popup alert?
