Why check box is not working fine in WinForms GridControl?

Cell value type

In the Boolean CellValueType, the check box selection will not work properly. The check mark will be enabled only after two clicks with the following code.

gridControl1[rowIndex, CheckBoxColumnIndex].CellValueType = typeof(bool);

gridControl1(rowIndex, CheckBoxColumnIndex).CellValueType = GetType(Boolean) 

Solution

This issue can be resolved by handling the intermediate option through the CheckBoxOptions property. Pass flateLook value as true to draw the flat checkbox, otherwise false.

gridControl1[rowIndex, CheckBoxColumnIndex].CheckBoxOptions = new GridCheckBoxCellInfo("true", "false", "indeterminate", true);

gridControl1(rowIndex, CheckBoxColumnIndex).CheckBoxOptions = New GridCheckBoxCellInfo("true", "false", "indeterminate", True)
