How to restrict CheckBox from being checked in WinForms GridControl?
Restrict the checkbox option
The CheckBox options can be restricted from being changed to the checked or unchecked state by using the CheckBoxClick event when the CheckBox cell is clicked. In the given sample, a message box shows up while clicking on the restricted CheckBox cell in our WinForms GridControl.
//CheckBox cell.
this.gridControl1[2, 2].CellType = "CheckBox";
this.gridControl1[2, 2].CheckBoxOptions = new GridCheckBoxCellInfo("true", "false", "false", true);
this.gridControl1[2, 2].CellValue = true;
this.gridControl1[2, 2].Description = "Restricted";
this.gridControl1[2, 4].CellType = "CheckBox";
this.gridControl1[2, 4].CheckBoxOptions = new GridCheckBoxCellInfo("true", "false", "false", true);
this.gridControl1[2, 4].CellValue = true;
this.gridControl1[2, 4].Description = "Enabled";
//Hooks the event in the Form_Load to restrict the CheckBox options from being clicked.
this.gridControl1.CheckBoxClick += gridControl1_CheckBoxClick;
void gridControl1_CheckBoxClick(object sender, Syncfusion.Windows.Forms.Grid.GridCellClickEventArgs e)
{
//Restricts the checkbox cell at [2,2] from clicking the options.
if (e.RowIndex == 2 && e.ColIndex == 2)
{
MessageBox.Show("The CheckBox options are restricted");
//Cancels the CheckBox click event.
e.Cancel = true;
}
}'CheckBox cell.
Private Me.gridControl1(2, 2).CellType = "CheckBox"
Private Me.gridControl1(2, 2).CheckBoxOptions = New GridCheckBoxCellInfo("true", "false", "false", True)
Private Me.gridControl1(2, 2).CellValue = True
Private Me.gridControl1(2, 2).Description = "Restricted"
Private Me.gridControl1(2, 4).CellType = "CheckBox"
Private Me.gridControl1(2, 4).CheckBoxOptions = New GridCheckBoxCellInfo("true", "false", "false", True)
Private Me.gridControl1(2, 4).CellValue = True
Private Me.gridControl1(2, 4).Description = "Enabled"
'Hooks the event in the Form_Load to restrict the CheckBox options from being clicked.
AddHandler Me.gridControl1.CheckBoxClick, AddressOf gridControl1_CheckBoxClick
Private Sub gridControl1_CheckBoxClick(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.Grid.GridCellClickEventArgs)

If e.RowIndex = 2 AndAlso e.ColIndex = 2 Then
