Is it easily possible to allow column reordering, but then restrict columns within groups to only be reordered within that group?

Similarly, columns not in a group cannot be moved into a group - where both situations at the moment allow the group to be split into two groups of the same name each with a subset of the group's columns.

 

Thanks,
Maurice

Hello Maurice,

You can handle the ColumnReordering event of RadGridView. The ColumnReorderingEventArgs give you the  NewDisplayIndex of the dragged column. Also you have e.Column.DisplayIndex - the current index of the dragged column. Having the Column and ColumnGroups properties of the RadGridView you can do the following:

- determine the maximum and minimum index for every group
        - check if the new index is outside the [min;max] boundary of he group
- set e.Cancel = true if drag is outside the range

I hope this approach fits well in your scenario.

Petar, that is the approach I took.
