Hi,

I am facing a wired GridView behavior. I have a GridView bound to a List of Objects. Nested inside is a RowDetailsTemplate and nested in that is a DataTemplate.

Now what is happening is that when i expand the last row of the Grid, scroll bars appear. whne i scroll down and then up all the rows expand. I haven't set any such property. And dont know how to control this. also when i select one row different rows are been selected.Below is the Xaml of the code. Could anyone please help. Really need your help. Thanks.

Hello Mateen,

Based on the code-snippet provided, I have tried to reproduce the issue you reported. However, I was not able to. So, in order to provide you with a more suitable solution, I would need a bit more details - what version of RadControls are you using, how do you handle the RowDetailsVisibilityChanged event ?
Still, I am sending you the sample project I used for testing the case so that you can use it for a reference.
