Hi,

I'm sure this is an easy issue but i'm struggling to find a solution on my own. Basically I want to get the name of the column that i made groupby it.


example:
.
1- I have data in my radgridview and i drag and drop on of the column to make group by it.

2- I have an event 
   
Private Sub ReportingGridView_GroupByChanged(sender As Object, e As GridViewCollectionChangedEventArgs) Handles ReportingGridView.GroupByChanged

End Sub


my question is : how I can return the name of the column that I made group by it??????????????

Hello Walid,

Thank you for writing.

In the GroupByChanged event you have access to the new group items via the GridViewCollectionChangedEventArgs.NewItems collection. It contains the GroupDescriptors that are currently applied:
private void radGridView1_GroupByChanged(object sender, GridViewCollectionChangedEventArgs e)
{
    //you are grouping by  and the Action=Add
    if (e.Action== Telerik.WinControls.Data.NotifyCollectionChangedAction.Add)
    {
        GroupDescriptor gd = e.NewItems[e.NewItems.Count - 1] as GroupDescriptor;
        RadMessageBox.Show(gd.GroupNames.First().PropertyName);
    }
}

I hope this information helps. Should you have further questions, I would be glad to help.

Regards,
Desislava
