Hi Luis,

Thank you for using Syncfusion Products.

We analyzed your query. Due to GridCheckBoxColumn behavior it does not fire any Editing events. Instead of editing events you can use CurrentCellvalueChanged event to get fired when the check box value is changed.
Code Example [C#]:

private void grid_CurrentCellValueChanged(object sender, CurrentCellValueChangedEventArgs args)

     {

            SfDataGrid grid = sender as SfDataGrid;

            int columnindex = grid.ResolveToGridVisibleColumnIndex(args.RowColumnIndex.ColumnIndex);

            var column = grid.Columns[columnindex];

            if (column.GetType() == typeof(GridCheckBoxColumn))

            {

                MessageBox.Show("Checkbox value changed ");

            }
     }

We have also prepared a sample based on this and you can download the sample from the below location,

Please let us know if you have any query.

Now as I get the value of GridCheckBoxColumn?

[Jai Ganesh S]

Hi Luis,

You can get the CheckBoxColumn value in CurrentCellValueChanged event by using the Rowindex like the below code example,
Code Example [C#]:

private void grid_CurrentCellValueChanged(object sender, CurrentCellValueChangedEventArgs args)

        {

            SfDataGrid grid = sender as SfDataGrid;

            int columnindex = grid.ResolveToGridVisibleColumnIndex(args.RowColumnIndex.ColumnIndex);

            var column = grid.Columns[columnindex];

            if (column.GetType() == typeof(GridCheckBoxColumn))

            {

                var rowIndex = this.grid.ResolveToRecordIndex(args.RowColumnIndex.RowIndex);

                var record = this.grid.View.Records[rowIndex].Data as Student;

                var value = record.IsCheck;

            }
        }   

We have also modified the  sample based on this and you can download the sample from the below location,

Whilst this is an old thread, I also have the same problem. I need to detect when checkbox cell changes in winforms sfdatagrid and I tried your solution but it doesn't work.

Visual Basic

Private Sub sfdatagrid_CurrentCellValueChanged (ByVal sender as object, ByVal e as CurrentCellValueChhangedEventArgs) Handles sfdatagrid.CurrentCellValueChanged

gives the following errors:

Type CurrentCellValueChangedEventArgs is not defined

Event CurrentCellValueChanged is not defined.

Syncfusion 17.1.0.47

Hi Tom, 

 

Thank you for using Syncfusion control. 

 

We  have checked the reported scenario. You can achieve the requirement to detect the checkbox cell changes by using  sfDataGrid.CellCheckBoxClick event. Please refer the below code snippet. 

 

AddHandler Me.sfDataGrid1.CellCheckBoxClick, AddressOf SfDataGrid1_CellCheckBoxClick 

 

Private Sub SfDataGrid1_CellCheckBoxClick(ByVal sender As Object, ByVal e As CellCheckBoxClickEventArgs) 

    MessageBox.Show("OldValueStatus " & e.OldValue.ToString() & vbCrLf & "NewValueStatus   " & e.NewValue.ToString()) 

End Sub
