Cell control is null right after i instantiate it

[test]

Could someone explain me why the cell control is null after the following operations?

grd.TableDescriptor.Columns[SOME_COLUMN_HEADER].Appearance.AnyRecordFieldCell.CellType = "Control";
grd.TableDescriptor.Columns[SOME_COLUMN_HEADER].Appearance.AnyRecordFieldCell.VerticalAlignment = Syncfusion.Windows.Forms.Grid.GridVerticalAlignment.Middle;
grd.TableDescriptor.Columns[SOME_COLUMN_HEADER].Appearance.AnyRecordFieldCell.HorizontalAlignment = Syncfusion.Windows.Forms.Grid.GridHorizontalAlignment.Center;

grdGroupingControl.Rows[rowIndex].Cells[colIndex].Control = new MyCustomControl();

thx

Hi Jack,

Sorry for the long delay in getting back to you.

You need to handle QueryCellStyleInfo event of GridGrouping Control to set the CellType. Below is the code snippet:

private void gridGroupingControl1_QueryCellStyleInfo(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableCellStyleInfoEventArgs e)
        {
            if (e.TableCellIdentity.RowIndex >= 4 && e.TableCellIdentity.ColIndex == 2)
            {
                e.Style.CellType = "Control";
                e.Style.Control = CB;
                System.Collections.Specialized.StringCollection sc = new System.Collections.Specialized.StringCollection();
                sc.Add("Australia");
                sc.Add("Canada");
                sc.Add("London");
                sc.Add("Swiz");
                e.Style.ChoiceList = sc;
            }
        }

Here is the sample that illustrates the same:
