Since you are not using a Telerik control(RadGrid), we'll need access to your application in order to assist you with this automation scenario. If direct access is not possible, you can point us to a similar public application and I'll be glad to assist you in finding the best solution. Alternatively, you can capture a Fiddler trace using FiddlerCap
and send it to us in a zip file. Basically with that trace I'll try to "simulate" your app locally and work on the issue. If you deem any of this information too sensitive for this forum, you can create a support ticket and attach it there. Thanks for providing the information we need to best assist you.
