Why the check box is not working fine when the CellValueType is set to bool in WinForms GridControl?

Platform: WinForms |
Control: GridControl |
Published Date: May 18, 2016 |

Cell value type

The Boolean CellValueType, the check box selection will not work properly. The check mark will be enabled only after 2 clicks with the following code,

C#

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

 

VB

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.

C#

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

 

VB

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

 

Samples:

C#: CheckBox_C#

VB: CheckBox_VB
