I have a setup that each row detail contains a child gridview, and when parent row is expanded, the child gridview should show all its rows, ie. no scrollbar because we don't want "double" scrollbars.
The issue is when the child gridview has many rows (in our case, 100), it takes a while (~6s) from expand the parent row to display all children rows.
Do you have any tips to speed up this scenario?

Hi Shrinand,
By default, the control placed within the RowDetails of the RadGridView is measured with infinity. On the other hand, when a RadGridView is measured with infinity - its UI Virtualization mechanism is broken. With this in mind, if you have such setup - you should set a fixed height for the inner RadGridView in order to not observe such performance degradation. Eventually, you can hide the ScrollViewer of the inner RadGridView. I have attached a sample for your reference.
