How to set custom text to a GroupRow in the CustomDrawGroupRow event of a DevExpress GridControl?

Question

I'm looking for a way of setting the GroupRow text inside the CustomDrawGroupRow event without setting e.Handled = true because I need the base drawing to also be applied:

this.gridView.CustomDrawGroupRow += (s, e) => 
{
    /* set the GroupRow text here without using e.Handled = true */
}

I've tried using e.Graphics.DrawString but then I can't use e.Appearance.BackColor because I need to set e.Handled = true to draw the string which disables it

You need to cast the e.Info as GridGroupRowInfo and set GridGroupRowInfo.GroupText to your value:

using DevExprss.XtraGrid.Views.Grid.ViewInfo;

...

this.gridView.CustomDrawGroupRow += (s, e) => 
{
    GridGroupRowInfo groupInfo = e.Info as GridGroupRowInfo;
    groupInfo.GroupText = "Custom group text";
}
