I don't know if it is possible, but I am trying to make a custom window that looks like the image attached. I am troubled by how to make the tab and the look to it. The window title would be on the top left tab looking piece. Any help would be appreciated.

Hi,

how do i find a textbox on "EditEnded"? I have a RadDataform with an EditTemplate. Now i use a textbox like this:

<DataTemplate x:Key="MyEditTemplate">

<Grid>

<Grid.ColumnDefinitions>

<ColumnDefinition Width="auto"/>

<ColumnDefinition Width="*"/>

</Grid.ColumnDefinitions>

<Grid.RowDefinitions>

<RowDefinition Height="Auto" />

<RowDefinition Height="40"/>

<RowDefinition Height="Auto" />

</Grid.RowDefinitions>

<telerik:DataFormDataField Label="{Binding Source={StaticResource Lang}, XPath=SettingsHost/@Header}" DataMemberBinding="{Binding Host, Mode=TwoWay}" Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="2" />

<telerik:DataFormDataField Label="{Binding Source={StaticResource Lang}, XPath=SettingsMandant/@Header}" DataMemberBinding="{Binding Mandant, Mode=TwoWay}" Grid.Row="2" Grid.Column="0" Grid.ColumnSpan="2" />

<telerik:DataFormDataField Label="{Binding Source={StaticResource Lang}, XPath=SettingsPort/@Header}" DataMemberBinding="{Binding Port, Mode=TwoWay}" Grid.Row="3" Grid.Column="0" Grid.ColumnSpan="2" />

Error Creating VB RadControls WPF Application (Telerik.VSX.Xaml.2013.1.215.0.dll not found)

I just installed WPF controls package for Visual Studio. I am having an issue creating a VB RadControls WPF Application. I am selecting the VB RadControls WPF Application options and in the configuration wizard I am selecting Use Implicit Styles and for components I am only selecting Telerik.Windows.Controls. After selecting a theme it pops up this error during the install.

An error occurred while running the wizard.

Error executing custom action Telerik.VSX.TextTemplating.Actions.UnfoldFilesAction: Compiling transformation: Metadata file 'Telerik.VSX.Xaml.2013.1.215.0.dll' could not be found

I have tried updating the WPF VSExtensions from the extensions manager as well as just uninstalling and reinstalling them.

I can create a RadControls Windows Forms Application just fine. It’s just the WPF applications that are the issue.

Any thoughts on how to fix this issue would be appreciated.

I am running:

Win 7 Pro 64bit

vs2012

I also have these other Telerik Applications installed:

Windows Forms

Reporting

JustCode

JustTrace

JustDecompile

Thanks

Documents That Don't Autohide

We are migrating from Actipro to Telerik docking. What I am wondering if it is possible what we did with Actipro. The tabs down the right side is actually a tab control that opens the Actipro docking windows. But please notice that that when you do an autohide, no tab is created. The tabs on the right basically tell the corresponding window to open or shut.
