  • Kendo UI Combo Box Reset Value

    - by ciantrius
    I'm using the Kendo UI ComboBoxes in cascade mode to build up a filter that I wish to apply. How do I clear/reset the value of a Kendo UI ComboBox? I've tried: $("#comboBox").data("kendoComboBox").val(''); $("#comboBox").data("kendoComboBox").select(''); $("#comboBox").data("kendoComboBox").select(null); all to no avail. The project is an MVC4 app using the Razor engine and the code is basically the same as the Kendo UI example.

  • maxlength attribute of a text box from the DataAnnotations StringLength in MVC2

    - by Pervez Choudhury
    I am working on an MVC2 application and want to set the maxlength attributes of the text inputs. I have already defined the stringlength attribute on the Model object using data annotations and it is validating the length of entered strings correctly. I do not want to repeat the same setting in my views by setting the max length attribute manually when the model already has the information. Is there any way to do this? Code snippets below: From the Model: [Required, StringLength(50)] public string Address1 { get; set; } From the View: <%= Html.LabelFor(model => model.Address1) %> <%= Html.TextBoxFor(model => model.Address1, new { @class = "text long" })%> <%= Html.ValidationMessageFor(model => model.Address1) %> What I want to avoid doing is: <%= Html.TextBoxFor(model => model.Address1, new { @class = "text long", maxlength="50" })%> Is there any way to do this?

  • C# - Fill a combo box with a DataTable

    - by MrG
    I'm used to work with Java where large amounts of examples are available. For various reasons I had to switch to C# and trying to do the following in SharpDevelop: // Form has a menu containing a combobox added via SharpDevelop's GUI // --- Variables languages = new string[2]; languages[0] = "English"; languages[1] = "German"; DataSet myDataSet = new DataSet(); // --- Preparation DataTable lTable = new DataTable("Lang"); DataColumn lName = new DataColumn("Language", typeof(string)); lTable.Columns.Add( lName ); for( int i=0; i<languages.Length; i++ ) { DataRow lLang = lTable.NewRow(); lLang["Language"] = languages[i]; lTable.Rows.Add(lLang); } myDataSet.Tables.Add(lTable); // --- Handling the combobox mnuActionLanguage.ComboBox.DataSource = myDataSet.Tables["Lang"].DefaultView; mnuActionLanguage.ComboBox.DisplayMember = "Language"; One would assume to see some values in the dropdown, but it's empty. Please tell me what I'm doing wrong ;( EDIT: mnuActionLanguage.ComboBox.DataBind() is what I also found on the net, but it doesn't work in my case. SOLUTION mnuActionLanguage.ComboBox.BindingContext = this.BindingContext; at the end solved the problem!

  • How to change VS2010 Add Reference box filter ?

    - by rook
    I'm getting used to the new IDE (it's vc# express), but the first contact is somewhat confusing. When I open the Add Reference dialog and switch to the .NET tab, a label above the assembly list states: "Filtered to:.NET Framework 4". And it's true - I can reference .NET 4.0 assemblies only plus things like XNA 3.1. However I can't see older assemblies i.e. Managed DirectX libs, which are obviously installed on my computer as there was no trouble with adding a ref to them in vc#08. What is this? How to change the filter? The label is read-only. These sound like dull guy's questions, but I'm out of lack of finding an answer and there is no intuitive solution. Thanks in advance.

I am sure this is a very simple change, but I can't seem to figure it out. Let me know if you need more details. Thanks, Chase

How can I make this happen? I'm open to a modalpopup or any other type of error message, I just want to ensure the user stays on the page where they encounter the error. Thank for any ideas.

  • TwoWay Binding to ListBox SelectedItem on more than one list box in WPF

    - by Dan Bryant
    I have a scenario where I have a globally available Properties window (similar to the Properties window in Visual Studio), which is bound to a SelectedObject property of my model. I have a number of different ways to browse and select objects, so my first attempt was to bind them to SelectedObject directly. For example: <ListBox ItemsSource="{Binding ActiveProject.Controllers}" SelectedItem="{Binding SelectedObject, Mode=TwoWay}"/> <ListBox ItemsSource="{Binding ActiveProject.Machines}" SelectedItem="{Binding SelectedObject, Mode=TwoWay}"/> This works well when I have more than one item in each list, but it fails if a list has only one item. When I select the item, SelectedObject is not updated, since the list still thinks its original item was selected. I believe this happens because the two way binding simply ignores the update from source when SelectedObject is not an object in the list, leaving the list's SelectedItem unchanged. In this way, the bindings become out of sync. Does anybody know of a way to make sure the list boxes reset their SelectedItem when the SelectedObject is not in the list? Is there a better way to do this that doesn't suffer from this problem?

  • javascript onkeypressed not giving current text box content

    - by Austin
    I have an html form like this: <form id="boxy" action="layout.html" method="get" accept-charset="utf-8"> <input type="text" id="a" onkeypress="Boxy.Check(this);"> </form> Invoking javascript like this: Boxy.Check = function() { input = document.getElementById(this.currentSelector.id).value; console.log("\"" + input + "\""); }; However, this.value is the previous value before onkeypress. For example, if I just type "A" into the form, console.log() prints "". And if I type "AA", console.log prints "A". Is there a way to get the current content of the input?

  • Help with inner content box margins/padding

    - by Wolfgang
    I am working on a layout for a new site, and I'm having some trouble achieving what I want with the CSS. First of all, I want everything to always stay within the view of the current browser window, with scroll being in my content and not the browser itself. I have an outermost DIV which acts as my "wrapper" for the site displayed centered, with a set width, and having 100% height of the bowser window. Inside of this I place a header and all of this works as intended in all interested browsers. However, once I place my actual content DIV inside this "wrapper" I am unable to define it to be the size I want. If I simply give it margins or padding to make up for the header I have absolutely positioned, the content will overflow and I can't set scroll. And if I try to set the size directly, there are no values I can put in that will work since the margins/padding will add to the size and it will now be bigger than the current browser window, and overflow. Are there any styles people can think of I can use on the wrapper/content DIV(s) to get the desired look? Here is a diagram illustrating the look I want.

  • Java Simple Chat Box

    - by Allen
    I am trying to create a very simple chat window that simply has the ability to display some text, which i add to from time to time. However I get the following run time error when attempting to append text to the window: java.lang.ClassCastException: javax.swing.JViewport cannot be cast to javax.swing.JTextPane at ChatBox.getTextPane(ChatBox.java:41) at ChatBox.getDocument(ChatBox.java:45) at ChatBox.addMessage(ChatBox.java:50) at ImageTest2.main(ImageTest2.java:160) Here is the class to handle the basic operations: public class ChatBox extends JScrollPane { private Style style; public ChatBox() { StyleContext context = new StyleContext(); StyledDocument document = new DefaultStyledDocument(context); style = context.getStyle(StyleContext.DEFAULT_STYLE); StyleConstants.setAlignment(style, StyleConstants.ALIGN_LEFT); StyleConstants.setFontSize(style, 14); StyleConstants.setSpaceAbove(style, 4); StyleConstants.setSpaceBelow(style, 4); JTextPane textPane = new JTextPane(document); textPane.setEditable(false); this.add(textPane); } public JTextPane getTextPane() { return (JTextPane) this.getComponent(0); } public StyledDocument getDocument() { return (StyledDocument) getTextPane().getStyledDocument(); } public void addMessage(String speaker, String message) { String combinedMessage = speaker + ": " + message; StyledDocument document = getDocument(); try { document.insertString(document.getLength(), combinedMessage, style); } catch (BadLocationException badLocationException) { System.err.println("Oops"); } } } if there is a simpler way to do this, by all means let me know. I only need the text to be of a single font type, and uneditable by the user. Aside from that, I just need to be able to append text on the fly.

  • Value of text box disapears - binding viewmodel to a tab (content control)

    - by Eli Perpinyal
    Based on the MVVM example by Josh Smith, I have implemented the multi tab option which binds to a different tab to a different view model using a simple datatemplate that binds a viewmodel to a view. <DataTemplate DataType="{x:Type fixtureVM:SearchViewModel}"> <SearchVw:SearchView/> </DataTemplate> The issue that I'm having, is when I switch tabs and then switch back again, the value in the textbox disappears. When I bind the Text in the textbox to a value in the ViewModel it does not disappear. This is fine, and I can overcome this but I am having another issue for example with the position of the scroll bar in a grid disappearing once the tab has lost focus. Why is the value disappearing? I'm assuming it is a WPF sub system task that cleans up resources!? how can I avoid this? I also feel it might be slowing down my app.

  • Asp.net text box is only returning the first value

    - by queryne
    C sharp newbie question...I have a simple asp.net form that has a textbox that collects phonenumbers to send SMS messages. If I bypass the form and hardcode the numbers using the following format: "2133211234",#1233211234" the code works fine. However when i try to use this same format using my form, the sms will ONLY send to the first number. I have a feeling i'm missing out on some property on my form that will accept all of the values. also any idea how how i can add some lines of code that will allow users to enter numbers like this: 3123211234,4123212344 and have it converted to the format above when the number is submitted? Any ideas? Thanks in advance.

  • C# searching for new Tool for the tool box, how to template this code

    - by Nix
    All i have something i have been trying to do for a while and have yet to find a good strategy to do it, i am not sure C# can even support what i am trying to do. Example imagine a template like this, repeated in manager code overarching cocept function Returns a result consisting of a success flag and error list. public Result<Boolean> RemoveLocation(LocationKey key) { List<Error> errorList = new List<Error>(); Boolean result = null; try{ result = locationDAO.RemoveLocation(key); }catch(UpdateException ue){ //Error happened less pass this back to the user! errorList = ue.ErrorList; } return new Result<Boolean>(result, errorList); } Looking to turn it into a template like the below where Do Something is some call (preferably not static) that returns a Boolean. I know i could do this in a stack sense, but i am really looking for a way to do it via object reference. public Result<Boolean> RemoveLocation(LocationKey key) { var magic = locationDAO.RemoveLocation(key); return ProtectedDAOCall(magic); } public Result<Boolean> CreateLocation(LocationKey key) { var magic = locationDAO.CreateLocation(key); return ProtectedDAOCall(magic); } public Result<Boolean> ProtectedDAOCall(Func<..., bool> doSomething) { List<Error> errorList = new List<Error>(); Boolean result = null; try{ result = doSomething(); }catch(UpdateException ue){ //Error happened less pass this back to the user! errorList = ue.ErrorList; } return new Result<Boolean>(result, errorList); } If there is any more information you may need let me know. I am interested to see what someone else can come up with. Marc solution applied to the code above public Result<Boolean> CreateLocation(LocationKey key) { LocationDAO locationDAO = new LocationDAO(); return WrapMethod(() => locationDAO.CreateLocation(key)); } public Result<Boolean> RemoveLocation(LocationKey key) { LocationDAO locationDAO = new LocationDAO(); return WrapMethod(() => locationDAO.RemoveLocation(key)); } static Result<T> WrapMethod<T>(Func<Result<T>> func) { try { return func(); } catch (UpdateException ue) { return new Result<T>(default(T), ue.Errors); } }
