Increasing the number of items in a combo box

[Stephen Rose]

Our users would like our combo box cells to show more items when they are dropped down. How would I go about doing this?

Hi Steve,

Thank you for your interest in Syncfusion product.

Please try setting the DrowDownRows property to resize the dropdown height. This can be achieved by handling the TableControlCurrentCellShowingDropDown event. In the event, the GridComboBoxCellRenderer is retrieved and DropDownRows property is to set the required. The following is the code snippet.

>>>>>
private void gridGroupingControl1_TableControlCurrentCellShowingDropDown(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlCurrentCellShowingDropDownEventArgs e)
{
GridCurrentCell cc = this.gridGroupingControl1.TableControl.CurrentCell;
GridComboBoxCellRenderer cr = cc.Renderer as GridComboBoxCellRenderer;
if(cc != null)
{
if (cc.RowIndex == 4 && cc.ColIndex==1)
{
((GridComboBoxListBoxPart)cr.ListBoxPart).DropDownRows =1;
}
else if(cc.RowIndex == 5 && cc.ColIndex==1)
((GridComboBoxListBoxPart)cr.ListBoxPart).DropDownRows = 10;
}
}
