How to pre-select checkbox inside a grid cell in WinForms GridControl

11 Jun 20211 minute to read

You need to set a style member called CheckBoxOptions for a particular grid cell, for this purpose. CheckBoxOptions.CheckedValue is used to specify what value should be given in the CellValue to make the checkbox checked.

If you want “true” to be checked and “false” to be unchecked state then use the below code.

C#
VB.NET
//Sets the cell type as Checkbox.
this.gridControl1[1,1].CellType = "CheckBox"; 

//Sets the Checked and Unchecked values for the checkbox.
this.gridControl1[1,1].CheckBoxOptions.CheckedValue = "true"; 
this.gridControl1[1,1].CheckBoxOptions.UncheckedValue = "false"; 

//Sets the type of the cell value as bool.
this.gridControl1[1,1].CellValueType = typeof(bool); 

//Sets the Cell value.
this.gridControl1[1,1].CellValue = true;
'Sets the cell type as Checkbox.
Me.gridControl1(1, 1).CellType = "CheckBox" 

'Sets the Checked and Unchecked values for the checkbox.
Me.gridControl1(1, 1).CheckBoxOptions.CheckedValue = "true" 
Me.gridControl1(1, 1).CheckBoxOptions.UncheckedValue = "false" 

'Sets the type of the cell value as bool.
Me.gridControl1(1, 1).CellValueType = GetType(Boolean) 

'Sets the Cell value.
Me.gridControl1(1, 1).CellValue = True
