Hi,

I have a requirement where some of the group should not be collapsible, so I have added the below code on OnGroupCollapsed method where I am checking if the group is "Component #1" then we are setting the group.IsExpand=True.

private void SfDataGrid_OnGroupCollapsed(object sender, GroupChangedEventArgs e)

{

if (e.Group.Key.Equals("Component #1"))

{

e.Group.IsExpanded = true;

}

}

With this above code what we are noticing is that for the group "Component #1" when user clicks on collapse the group does not collapse [As needed] but what i also notice is that some of the rows down below are getting removed and we are getting an ArgumentOutofRangeException.

Can you please let me know why we are getting this exception when we are not deleting any row here. Attached is the sample application.

Thanks
