Hi Helmut,
Please try the code below in the TableControlDrawCellDisplayText event of the gridGroupingControl. This will help you.
if(e.TableControl.Table.CurrentElement is GridRecord)
{
float width = e.Inner.Graphics.MeasureString(e.Inner.DisplayText, e.Inner.Style.GdipFont).Width;
if(width > e.Inner.TextRectangle.Width)
{
e.Inner.DisplayText = "##";
}
}
Let me know if you need any further assistance.
Regards,
Rajagopal
