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,

Hi,
we need saving the fields Alt and Tag of the images (ImageInline objects ) but when we try to export in docx using Export method of DocxFormatProvider these fields are lost.
Is there a way to save the values of these fields in docx format?

Thank you.

I can't seem to find 3d chart demos either in the xaml sdk repository (https://github.com/telerik/xaml-sdk) or in the wpf demo application, is this feature no longer supported? I was trying to make a doughnut3d to work, but I get a StackTrace-less stackoverflow exception in runtime

.

Xaml:

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.

 Is it possible RadHeatMap axes SmartLabelsMode="SmartStep" ? As you can see in the attached image , when I have a lot of data , labels overlap. Is there any solution in radhepmap ? In radcartesianchart with SmartStep the problem is solved.

Gerard.

Objective:  To filter the listbox (Computers) and select an item whose value matches exactly with that of textbox (Search) value.

Considerations:

1) The items from the listbox are binded from the database.
2) The item in the listbox should be selected by default when textbox value matches with the listbox item.

Please help me on this

Hi,

Look the first image on this page: http://docs.telerik.com/devtools/wpf/controls/radgauge/features/indicators/needle.html

I obtains exactly the same result, the 6 value tick disappears and the scale is not linear.

Thanks, marc.

Hi,

I have a wcf service which return me list of items.

I wanted to use this service as Data Virtualization in wpf example.

For ex

I wanted to show 50 customers in the grid and when user scolls down to grid end, grid should be populated with next 50 customers.

I don't want to use WCF RIA/Data services, I have already existing wcf service which gives me list.

Please help me to achieve this.
