Limit number of columns to group by?

[Kjell]

Hi, is there a way to limit how many columns a user can group by?  I would like to limit them to 4 columns.

Ok I figured out I can look at the groupcount and then cancel additional grouping in the "Grouping" event, but is there a better way?

Hello Kjell,

 Currently this is the only way (Grouping event) to achieve this.

Kind regards,

Hi , can you please provide the code you have used to limit the columns to group by?

Sure, the name of my grid is "rgvEvents" and this is my "Grouping" event handler.

void rgvEvents_Grouping(object sender, GridViewGroupingEventArgs e)
        {
            try
            {
                //don't allow more than 3 groups at a time
                if (rgvEvents.GroupCount > 3 && e.Action == Telerik.Windows.Controls.GroupingEventAction.Place)
                {
                    e.Cancel = true;
                }
            }
            catch { }
        }
