Auto Resizing Problem

I have following window:

<telerik:RadWindow x:Class="IdealHost.FaceToFace.Controls.MessageBox" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" MinHeight="140" MinWidth="300"

WindowStartupLocation="CenterOwner" ResizeMode="NoResize" >

<Grid>

<Grid.ColumnDefinitions>

<ColumnDefinition Width="80" />

<ColumnDefinition Width="*" />

</Grid.ColumnDefinitions>

<Grid.RowDefinitions>

<RowDefinition Height="Auto" />

<RowDefinition Height="*" />

</Grid.RowDefinitions>

<TextBlock VerticalAlignment="Center" HorizontalAlignment="Stretch" Grid.Row="0" Grid.Column="1" Margin="15,10,15,10" Name="txtMessage" />

</Grid>

</telerik:RadWindow>

When I'm assigning text using following code:

this.txtMessage.Text = message;

The window is propery resized to size of text.

But when I change TexBlock to use Binding:

<TextBlock VerticalAlignment="Center" HorizontalAlignment="Left" Grid.Row="0" Grid.Column="1" Margin="15,10,15,10" Text="{Binding Message}"/>

The window is not automatically resizing. And text is cut.

How can I fix this issue? I realy would like to use binding not direct code.

Purpose of RadPane Scenario

What's the use / purpose of the RadPane Scenario when creating a new RadPane? A new xaml definition page is generated with <telerik:RadPane> as the closing / ending tag, and the designer will show the Header value, but you create content all day long but the content will never appear in the designer. The only way content is display is to run the application. Why does the designer not show the content as the xaml is being entered in the editor?

Drag N Drop B/w RadGridView N Desktop..

Hi,

I have a WPF control which has RADGridView in it. I included that control inside a Windows Form using element host. But when I started dragging GridView row outside the element host it doesn't let me do that.

Another problem I wanted to drop a row from RagGridView to Desktop. How can I implement that. It would be nice if you respond promptly.

Thanks in Advance..
