DataGridView＆amp; ComboBox活动？

Question

使用VB.Net，我有一个带有ComboBox列的DataGridView。当用户更改ComboBox中的选择时，我甚至可以使用什么？

Answer 1

当选择了组合框值时，您可以执行此事件...

Private Sub dataGridView_EditingControlShowing(ByVal sender As Object, ByVal e As DataGridViewEditingControlShowingEventArgs)
    Try 
        If (Me.dataGridView.CurrentCell.ColumnIndex = CType(Column.Col,Integer)) Then
            Dim comboBox As ComboBox = CType(e.Control,ComboBox)
            If (Not (comboBox) Is Nothing) Then
                AddHandler comboBox.SelectedIndexChanged, AddressOf Me.ComboBoxIndexChanged
            End If
        End If
        Return
    Catch Ex As Exception
        Utils.ErrMsg(Ex.Message)
        Return
    End Try
End Sub

SelectedValueChanged

Answer 3

.FormatedValue，如Grid.Item.FormatedValue而非Value

Answer 4

CurrentCellDirtyStateChanged - 然后测试您关注列中的当前单元格。
