The cellvaluechanged doesn't fire when a checkbox has been checked/unchecked.
(it does fire when leaving the cell, but that doesn't work for me)

The cellcontentclick is also not working as it should.
When repeatedly click the checkbox i can not ask what the current value is.

I've been testing and if i manualy set the checkbox value it seems to go ok

' In the CellContentClick-event
After processing the checked-change i have to execute the following command else it doesn't work.
DataViewGrid.CurrentCell.Value = Not DataViewGrid.CurrentCell.Value

Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick

       ' my check box colum is the last grid colum

        If e.ColumnIndex = (Me.DataGridView1.Columns.Count - 1) Then

            If Me.DataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex).Value = True Then

                Me.DataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex).Value = False

                MessageBox.Show(Me.DataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex).Value)
 

            Else

                Me.DataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex).Value = True

                MessageBox.Show(Me.DataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex).Value.ToString())

            End If
 

        End If
