number of lines in ComboBox

[Frederic Dubois]

Hi
I've tried to change the number of line of a combo box in a GridControl. But I never found a properties to change that. How can I change the number of row displayed, because only 6 rows is really not enough.

Hi Fredric,

This can be achieved by setting the DropDownRows property of the GridComboBoxListBoxPart to a specified value in the CurrentCellShowingDropDown event.

Please refer the code:

  
 
void gridControl1_CurrentCellShowingDropDown(object sender, GridCurrentCellShowingDropDownEventArgs e)
        {
            GridCurrentCell cc = this.gridControl1.CurrentCell;
            if (cc.Renderer is GridComboBoxCellRenderer)
            {
                GridComboBoxCellRenderer dr = cc.Renderer as GridComboBoxCellRenderer;
                ((GridComboBoxListBoxPart)dr.ListBoxPart).DropDownRows = 12;
            }
            
        }

Please let me know if this helps.

Regards,
Jisha
