Hello. could you watch this code?It works ,But cant check checkbox.It is not active.Despite I activated.And check column datatype is boolean.

private void besGrid2_InitializeLayout(object sender, InitializeLayoutEventArgs e)
{
DataTable dtb = new DataTable();
dtb.Columns.Add("ID", typeof(Int32));
dtb.Columns.Add("Text", typeof(string));
dtb.Columns.Add("Check",typeof(bool));

dtb.Rows.Add(new object[] { 1, "A" });
dtb.Rows.Add(new object[] { 2, "B" });
e.Layout.Bands[0].Columns[2].Style = ColumnStyle.CheckBox;
e.Layout.Bands[0].Columns[2].CellActivation = Activation.AllowEdit;
e.Layout.Bands[0].Columns[2].CellClickAction = CellClickAction.Edit;
this.besGrid2.DataSource = dtb;
}
