Hi, I have a radtree control and I am adding radgrid to its node programmatically.
I am setting the Scroll options on the grid to freeze the first two columns of the grid. However, the columns are not getting frozen? Any idea why..
I am setting the following properties on the grid.
grid.ClientSettings.Scrolling.UseStaticHeaders = Truegrid.ClientSettings.Scrolling.SaveScrollPosition = Truegrid.ClientSettings.Scrolling.FrozenColumnsCount = 2Also, I observe that now for all grids on the different nodes the grid's height is consant. I would want a variable height for the grid, depending on the number of records it has. How do I accomplish that?
Thanks

Hi Mark Kelly,
The described scenario is not supported out-of-the-box, as RadGrid needs to be visible on initial page load to adjust its frozen and non-frozen columns. You can use the following approach:
