Combobox items disappear

Hi,

I am currently working with Syncfusion 3.3. I have a GDBG and with a column of comboboxes. Each combobox gets it's ListBoxPart dynamically populated by the CurrentCellShowingDropDown event. Everything seems to be working properly except when a user clicks on the same cell that is already showing the dropdownlist. For some reason, the dropdownlist becomes entirely blank. Is there some other event I need to handle in order to avoid this situation?

Regards,
Brian

Hi Brian,

Please try the code below in the CellClick event of the grid to avoid this problem.

private void gridDataBoundGrid1_CellClick(object sender, GridCellClickEventArgs e)
{
    GridCurrentCell cc = this.gridDataBoundGrid1.CurrentCell;
    if(cc.IsDroppedDown)
    {
        cc.CloseDropDown(Syncfusion.Windows.Forms.PopupCloseType.Canceled); 
        cc.ShowDropDown(); 
        e.Cancel = true;
    }
}

Let us know if this helps.
