(empty) choice in filter bar for GDBG

The GGC filter bar has an (empty) option for filtering empty strings and I would like to add that to the GDBG filter bar options. Is that an option?
Thanks

Hi Prumery,

This can be achieved by deriving the GridFilterBar class and override GridFilterBarRow and CreateUnquieEnteries methods is handled to add the "[Empty]"option in a FilterBar. Please try it and let us know if you need any further assistance.

public class MyGridFilterBar : GridFilterBar
{ private GridDataBoundGrid grid1;
public override void WireGrid(GridDataBoundGrid grid, GridStyleInfo style)
{ this.grid1 = grid;
base.WireGrid (grid, style);
}
protected override string GetFilterFromRow(GridDataBoundGrid grid)
{ GridCurrentCell cc = grid.CurrentCell;
string s = cc.Renderer.ControlText;
string rowFilter = base.GetFilterFromRow(grid);
if(s != "[Empty]")
return rowFilter;
else
return rowFilter.Replace("[Empty]","") ;
}
protected override DataTable CreateUniqueEntries(DataView dv, string colName)
{ DataTable dtt = base.CreateUniqueEntries(dv,colName);
DataRow dr= dtt.NewRow();
dr[0]="[Empty]";
dtt.Rows.InsertAt(dr,2);
return dtt;
}
}

The following sample demonstrates above technique.
