DataGridView控件，输入大写，VB.NET实现

用惯了第三方控件fpspread，只一个属性就可以设置输入大写，可用微软原装的DataGridView缺很麻烦，查到一个C#实现，改成VB.NET版本

    Private Sub GridTaskList_EditingControlShowing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles GridTaskList.EditingControlShowing
        Dim dgv As DataGridView = CType(sender, DataGridView)
        If TypeOf (e.Control) Is DataGridViewTextBoxEditingControl Then
            Dim EditingControl As DataGridViewTextBoxEditingControl
            EditingControl = CType(e.Control, DataGridViewTextBoxEditingControl)
            If dgv.CurrentCell.OwningColumn.DataPropertyName = "Stope_Id" Then
                EditingControl.CharacterCasing = CharacterCasing.Upper
            Else
                EditingControl.CharacterCasing = CharacterCasing.Normal
            End If
        End If
    End Sub
