Setting a grid dropdown height

[Shane]

I have a dropdown in a grouping grid and I want the dropdown to resize depending and the number of items in the list. This is so all items will be displayed without the need for a vertical scroll bar.

Hi Shane,

This can be achieved by handled by the TableControlCurrentCellShowingDropDown event of GridGroupingControl. Please refer the code:

 this.gridGroupingControl1.TableControlCurrentCellShowingDropDown += new Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlCurrentCellShowingDropDownEventHandler(gridGroupingControl1_TableControlCurrentCellShowingDropDown);

      

        void gridGroupingControl1_TableControlCurrentCellShowingDropDown(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlCurrentCellShowingDropDownEventArgs e)
        {
            GridCurrentCell cc = this.gridGroupingControl1.TableControl.CurrentCell;
            if (cc.Renderer is GridComboBoxCellRenderer)
            {
                GridComboBoxCellRenderer dr = cc.Renderer as GridComboBoxCellRenderer;
                ((GridComboBoxListBoxPart)dr.ListBoxPart).DropDownRows = s.Count;
            }
        }

Please refer the sample:
