Problem loading the GridView Row Detials on demand

[SivaPrasad Bevara]

Hi,

I am using Telerikcontrols for Silverlight 5 and RIA services.

I wanted to display hierarchial data in the grids. For this I am using the Row Details feature of the Grid.

I am using MVVM pattern. I am binding data directly from the ViewModel through objects.

On the Expand click, I wanted to get the key field from the parent row and need to populate the child grid.
I am loading the Child grid in the "RowDetailsVisibilityChanged" event. I am able to access the parent row in the view model through commands.

But the problem is, When I load the data for a child grid on expand, it is updating all the child grids with the same data, which are already opened.

How can I load the data for the child grid which is currently opened, without updating the other child grids?

Please help.
