Try `DesrLabel.Content`. Its the WPF way.

In normal winForms, value of Label object is changed by,

    myLabel.Text= &quot;Your desired string&quot;;

But in WPF Label control, you have to use .content property of Label control
for example,

    myLabel.Content= &quot;Your desired string&quot;;



I believe you want to set the `Content` property. [This][1] has more information on what is available to a label.


  [1]: http://msdn.microsoft.com/en-us/library/system.windows.controls.label.aspx

You can use the Content property on pretty much all visual WPF controls to access the stuff inside them. There&#39;s a heirarchy of classes that the controls belong to, and any descendants of ContentControl will work in this way.

you can use TextBlock control and assign the text property.

`Label myLabel = new Label ();`
`myLabel.Content = &quot;Hello World!&quot;;`

Just trying to figure out how to use many multiple cases for a Java switch statement. Here&#39;s an example of what I&#39;m trying to do:

    switch (variable)
    {
        case 5..100:
            doSomething();
        break;
    }

versus having to do:

    switch (variable)
    {
        case 5:
        case 6:
        etc.
        case 100:
            doSomething();
        break;
    }

Any ideas if this possible, or what a good alternative is?

When trying to do a HTTP request using XMLHttpRequest from a local file, it basically fails due to `Access-Control-Allow-Origin` violation.

However, I&#39;m using the local web page myself, so I was wondering if there is any way to make Google Chrome allow these requests, which are from a local file to a URL on the Internet.

E.g., `$.get(&#39;http://www.google.com/&#39;)` fails when executing in a local file, but I&#39;ve scripted the page myself and I&#39;m using it myself, so it would be extremely useful if I could suppress it and load the URL.

So, how can I allow Google Chrome to load URLs using XMLHttpRequest from local files?

I feel stupid but cannot find out how to add a text to a WPF Label control in code. Like following for a TextBlock:

    DesrTextBlock.Text = &quot;some text&quot;;

 What is equivalent property in Label for doing it?

    DesrLabel.??? = &quot;some text&quot;; //something like this

Can private classes exist in C#, other than in Inner classes?

I know from [this question][1] that extension methods can only operate on class instances, not the static class itself.  This means I can&#39;t extend useful static classes like `Convert` and `Math`.

What I want to know is, why is this the case?  From the link above, there are some suggestions on how the C# team could have implemented this kind of functionality.  Is there some philosophical reason why it isn&#39;t supported?

For example, here&#39;s a [rationale][2] behind why there is no built-in LINQ `ForEach&lt;T&gt;` extension for `IEnumerable&lt;T&gt;`.

I want to redirect the Index action of the Home controller to another controller&#39;s action and nothing else. My code is thus:

        public void Index()
        {
            //All we want to do is redirect to the class selection page
            RedirectToAction(&quot;SelectClasses&quot;, &quot;Registration&quot;);
        }

Right now, this just loads a 0 kB blank page and does nothing. I have a feeling it has something to do with that void return type, but I don&#39;t know what else to change it to. What&#39;s the issue here?

Greetings everyone... I need to `Trim` a `String`. But I want to remove all the repeated blank spaces within the String itself, not only at the end or at the start of it. I could do it with a method like:

    public static string ConvertWhitespacesToSingleSpaces(string value)
    {
        value = Regex.Replace(value, @&quot;\s+&quot;, &quot; &quot;);
    }
Which I got from [here][1]. But I want this piece of code to be called within the `String.Trim()` itself, so I think I need to extend or overload or override the `Trim` method... Is there a way to do that?

Thanks in advance.

I&#39;m trying to call `System.Windows.Threading.Dispatcher.BeginInvoke`. The signature of the method is this:

    BeginInvoke(Delegate method, params object[] args)

I&#39;m trying to pass it a Lambda instead of having to create a Delegate.

    _dispatcher.BeginInvoke((sender) =&gt; { DoSomething(); }, new object[] { this } );

It&#39;s giving me a compiler error saying that I 

&gt; can&#39;t convert the lambda to a System.Delegate. 

The signature of the delegate takes an object as a parameter and returns void. My lambda matches this, yet it&#39;s not working. What am I missing?

I&#39;m new to WPF and want to do some basic databinding.
I have a List of a CustomObject and want to bind it to a DataGrid.

MainWindow.xaml.cs

 

       using System;
        using System.Collections.Generic;
        using System.Linq;
        using System.Text;
        using System.Windows;
        using System.Windows.Controls;
        using System.Windows.Data;
        using System.Windows.Documents;
        using System.Windows.Input;
        using System.Windows.Media;
        using System.Windows.Media.Imaging;
        using System.Windows.Navigation;
        using System.Windows.Shapes;
        
        namespace WpfApplication1
        {
            /// &lt;summary&gt;
            /// Interaction logic for MainWindow.xaml
            /// &lt;/summary&gt;
            public partial class MainWindow : Window
            {
                public MainWindow()
                {
                    InitializeComponent();
                    List&lt;ArticleItem&gt; list = new List&lt;ArticleItem&gt;() 
                    {
                    new ArticleItem(){ ID=3, Title=&quot;test&quot;, ViewCount=5},
                    new ArticleItem(){ ID=3, Title=&quot;test&quot;, ViewCount=5},
                    new ArticleItem(){ ID=3, Title=&quot;test&quot;, ViewCount=5},
                    new ArticleItem(){ ID=3, Title=&quot;test&quot;, ViewCount=5},
                    };
                }
            }
        
            public class ArticleItem 
            {
                public int ID { get; set; }
                public int ViewCount { get; set; }
                public String Title { get; set; }
            }
        }

This is how my grid looks like:

    &lt;DataGrid Height=&quot;179&quot; HorizontalAlignment=&quot;Left&quot; Margin=&quot;54,65,0,0&quot; Name=&quot;dataGrid1&quot; VerticalAlignment=&quot;Top&quot; Width=&quot;382&quot;&gt;
        &lt;DataGrid.Columns&gt;
            &lt;DataGridTextColumn Header=&quot;ID&quot;/&gt;
                &lt;DataGridTextColumn Header=&quot;ViewCount&quot; /&gt;
            &lt;DataGridTextColumn Header=&quot;Title&quot; /&gt;
        &lt;/DataGrid.Columns&gt;
    &lt;/DataGrid&gt;

I&#39;m used to the databinding from ASP.Net, where I can easily say:

    this.dataGrid1.DataSource = list;

How must I proceed in WPF?


How do I bind a List&lt;CustomObject&gt; to a WPF DataGrid?

I have this code (which works just right):

    &lt;KeyBinding Key=&quot;Enter&quot; Command=&quot;{Binding ReturnResultCommand}&quot;&gt;
        &lt;KeyBinding.CommandParameter&gt;
            &lt;s:Boolean&gt;
                True
            &lt;/s:Boolean&gt;
        &lt;/KeyBinding.CommandParameter&gt;
    &lt;/KeyBinding&gt;

Where &quot;s&quot; is of course the System namespace.

But this command is called quite a few times and it really inflates otherwise rather simple XAML code. Is this really the shortest notation of boolean command parameter in XAML (other than splitting the command into several commands)?

I have a **`TextBox`** and a Label. After clicking a button, I execute the following code:

     label1.Content = textbox1.Text; 

My question is, how do I enable text wrapping of the label? There may be too much text to display on one line, and I want it to automatically wrap to multiple lines if that is the case.

How can I wrap text in a label using WPF?

I am using DataGrids in XAML (not Silverlight) with resizable columns, the DataGrid will expand if the user resizes the screen.

Currently if the widths of all the DataGrid columns are less than the width of the DataGrid I get an extra &quot;column&quot; appearing which is unclickable and serves no purpose.

Does anyone know how to make one column always resize to fill all the remaining space?
