Dear all,

unfortunatly I have problems with the UltraDropDown. At the moment I have this:

            for (int irow = 0; irow < grid.Rows.Count; irow++)
            {
                UltraDropDown Combobox = new UltraDropDown();
                Combobox.SetDataBinding(dt, null);
                Combobox.DisplayMember = "Col1";
                Combobox.ValueMember = "Col2";
                grid.Rows[irow].Cells["CB"].ValueList = Combobox;

                grid.Rows[irow].Cells["CB"].Style = Infragistics.Win.UltraWinGrid.ColumnStyle.DropDown;
            }

but no DropDown-Menu is shown. What is wrong?

dt is a Datatable with 5 Columns (Col1,Col2,...,Col5) and shall be bound to grid during runtime.

Thank you in advance

Best regards

Alex
