Column Header UI Automation

[David]

Hi,

We are looking into the viability of using Rad Grid in our Silverlight application. During our investigation we have noticed that the rid headers appear invisible to UI Autoamtion insepctors such as UI Spy, we also can't see a way of making them visible. This is important to us as the column headers are used to sort the table, and we would need to a) expose this control for accesibility issues, and b) use it for our automated tests.

We would apreciate any feedback on this issue.

Regards,
Dave

Hi David,

The current release of RadGridView does not support automation of the column headers but after your post we have decided that it is high time to introduce such automation peers.

We have managed to implement those peers and they are now being tested by our QA team. I should be able to send you a custom build by Wednesday so that you can test drive the new functionality.

Your feedback is greatly appreciated.
I have updated your Telerik points.
