How to Customize the Group Text of a DevExPress Grid View

If you need to customize the Group Text during runtime then you can handle the GridView's CustomDrawGroupRow event.

Let's say you have a GridView and you are grouping the data according to Project Number. But while showing the group text you want to show both Project Number and Project Name (ex. 001 - Demo Project). Where '001' is the project number and 'Demo Project' is the name of the project.

First of all you have to set gcProjectNo.GroupIndex = 0;

Then you have to handle the CustomDrawGroupRow event.

private void grdvProjectList_CustomDrawGroupRow(object sender, DevExpress.XtraGrid.Views.Base.RowObjectCustomDrawEventArgs e)

{

GridView view = sender as GridView;

DevExpress.XtraGrid.Views.Grid.ViewInfo.GridGroupRowInfo info =

e.Info as DevExpress.XtraGrid.Views.Grid.ViewInfo.GridGroupRowInfo;

int handle = view.GetDataRowHandleByGroupRowHandle(e.RowHandle);

if (info.Column.FieldName == "PRJ_NO")

{

StringBuilder oGroupText = new StringBuilder();

oGroupText.Append(view.GetRowCellValue(handle, "PRJ_NO").ToString());
