Problem with header in Office2013 theme

Hello,
the Office2013 theme corrects the text of the header so that they are in uppercase.
This work correctly when we just set the header as a text, but not if we want to customize it, for example to add an image or something else. It seems that the theme takes the Text property of the header content, converts it to uppercase and use the result to display in the header. If the header content doesn't contain a Text property, nothing is displayed.

To see this in action, just create a WPF application, add the relevent assemblies and replace MainWindow.xaml with:

<Window

x:Class="Test_GridView_header_Office2013.MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:tk="http://schemas.telerik.com/2008/xaml/presentation"

Title="MainWindow" Height="350" Width="525">

<tk:RadGridView Margin="10">

<tk:RadGridView.Columns>

<tk:GridViewDataColumn Header="Direct text" />

<tk:GridViewDataColumn>

<tk:GridViewDataColumn.Header>

<StackPanel>

<TextBlock Text="Header with a stack panel" />

</StackPanel>

</tk:GridViewDataColumn.Header>

</tk:GridViewDataColumn>

</tk:RadGridView.Columns>

</tk:RadGridView>

</Window>

If you run the application, you will see that the first header is displayed, but not the second one...
In all other themes I tested, including Windows8, both headers are displayed.

To correct the problem, I think that the best solution is to check whether the header has a Text proprty. If there is none, you should display the header as defined by the user, without changing it.

[Solved] Grouping in RadGridView - crash

Hello, I am getting the following exception when using grouping in RadGridView. The problem is that the exception seems to happen not inside my code,
but entirely inside Telerik RadGridView control, so I cannot catch the exception. Any tips how to catch this exception or better - avoid the exception from occuring? I using the Telerik version 2016.1.217.40. My twitter handle is @Tore_Aurstad. Nice if you got any tips, we are closing in on our release date for our client which is using the Telerik WPF library heavily.

Thanks,

Diagram Control Issue during Dragging

I have a diagram control, and I was drawing an arrow across it. I did this as ATP using Microsoft Coded UI. It recorded the sequence of steps correctly as well as the dragging, however, in the code behine it put this statement as a comment.

System parameter 'Show window contents while dragging' is not set.This could lead to incorrect recording of drag actions

when running the ATP, when it comes to the stage of drawing the arrow, it just does not, stays there as though nothing is happening. Any advice whats happening? The particular windows system parameter is set to show contents when dragging. using windows server 2008 R2.
