Disabling grouping in PreRender

[JP]

Hello,

I want to disable the grouping in Grid's PreRender event but have trouble doing so. I believe this event is too late to disable grouping.
What other possibilities do I have?

Currently I'm doing this in Grid's PreRender event:

bool enableGrouping = settings.EnableGrouping && GroupingEnabled;
grid.GroupingEnabled = settings.EnableGrouping;
grid.ShowGroupPanel = settings.EnableGrouping;
grid.ClientSettings.AllowDragToGroup = enableGrouping;
grid.GroupingSettings.ShowUnGroupButton = enableGrouping;

But grouping is still possible. I don't want to hide the grouing header (which would work).

Thanks!

Hello JP,

Generally, there are earlier events like Init or Load which you can try. I've created a sample RadGrid web site to test the described behavior and on my side the dragging of column headers is disabled as expected. Please run the attached application and let me know about the result.
