I've used RadGrid and inside that I have one listview with expander control. It is working fine and Expander also expanding and collapsing fine.
But only one issue I have is, when I expanded the Expander and try to scroll down the RadGrid, Expander collapsing every time, it is not retaining it's previous expand state.
I could overcome this by disabling the Virtualization on RadGrid but in that case RadGrid taking long time to load/render.
Any help would be appreciated.
