Using Windows Narrator (or our automated testing tool) our app crashes with the following stack trace:

at System.Collections.Generic.List`1.InsertRange(Int32 index, IEnumerable`1 collection)

   at System.Collections.Generic.List`1.AddRange(IEnumerable`1 collection)

   at Telerik.Windows.Controls.RadTabControlAutomationPeer.GetChildrenCore()

   at System.Windows.Automation.Peers.AutomationPeer.EnsureChildren()

   at System.Windows.Automation.Peers.AutomationPeer.UpdateChildrenInternal(Int32 invalidateLimit)

   at System.Windows.Automation.Peers.ItemsControlAutomationPeer.UpdateChildren()

This didnt happen with the Telerik trial dll's (version 2012.2.0725.40) but does happen since we received our licensed dll's (versions 2012.2.0912.40 and 2012.2.0929.40)

I would have raised this as a support ticket but my Telerik account isnt linked to our license at present. 

Thanks

Hi Alex,

This is a known issue and it was introduced with versions 2012.2.0912.40, however it is already fixed. I am not sure what you mean with "version 2012.2.0929.40", because there is no internal build with such a version. There is an internal build on 24th September and after that there is one on 1st October. You can find the fix of this issue in both of those internal builds.

Please give one of them a try and write us back if it works for you.

We think we may be seeing similar issues w/ the Silverlight controls, has this UIAutomation WPF fix made it into the SL controls?

Hi Jeremy,

The fix is made and tested for both platforms - Silverlight and WPF.

However if you find any similar issues please send us a sample project reproducing the issues.

Kind regards,

I am experiencing this issue with Telerik Q2 2013 WPF controls.


The controls that I am using are TileList, AutoComplete, ComboBox, and GridView. When I turn on Narrator. I get the following error:

Hello Mark,

 I have answered your ticket and I'm pasting the answer also here: 

"We are not aware of such bug. We would kindly ask you to create and send us a sample project where we could reproduce this bug which would be of great help for us to find out why or in which case this issue occurs."
