Examples

C#

                    GenericPartClass gp = item.Cells[0].Parts[0];
                    if (gp is CheckBoxPartClass) {
                        CheckBoxPartClass cb = (CheckBoxPartClass) gp;
                        cb.State = cb.State == CheckBoxStateEnum.Checked ? CheckBoxStateEnum.Unchecked : CheckBoxStateEnum.Checked;
                        e.Handled = true;
                        // changing the checkbox state doesn't automatically call the CheckBoxClicked event
                        CellClass owningCell = (CellClass)cb.PartOwner;
                        ItemClass owningItem = owningCell.OwningItem;
                        sftTree1_CheckBoxClicked(this, new PartEventArgs(owningItem, owningCell, null, cb));
                    } else if (gp is RadioButtonPartClass) {
                        RadioButtonPartClass rb = (RadioButtonPartClass)gp;
                        if (sftTree1.PerformClick_RadioButtonPart(rb)) {
                            e.Handled = true;
                            // changing the radiobutton state doesn't automatically call the RadioButtonClicked event
                            CellClass owningCell = (CellClass) rb.PartOwner;
                            ItemClass owningItem = owningCell.OwningItem;
