Telerik RadGridView for Winforms中文本框列的编辑模式

Question

我在Winforms中开发了一个带有两个GridViewTextBoxColumn属性的RadGridView。这里的问题是我无法编辑RadGridView文本框中的文本。当我单击单元格时，程序停止运行。我在下面发布了一些代码。

请建议我一个解决方案。任何帮助表示赞赏。

 Dim textboxColumn As GridViewTextBoxColumn
  textboxColumn = CType(Me.RadGridView1.Columns("Name"), GridViewTextBoxColumn)
            textboxColumn.HeaderText = "Name"
            textboxColumn.IsVisible = True
            textboxColumn.WrapText = True
            textboxColumn.Width = 100
            textboxColumn.MinWidth = 200
            textboxColumn.MaxWidth = 200
            textboxColumn.Multiline = True
            Me.RadGridView1.Columns.Move(textboxColumn.Index, 0)

            textboxColumn = CType(Me.RadGridView1.Columns("Description"), GridViewTextBoxColumn)
            textboxColumn.HeaderText = "Description"
            textboxColumn.IsVisible = True
            textboxColumn.WrapText = True
            textboxColumn.Width = 100
            textboxColumn.MinWidth = 200
            textboxColumn.MaxWidth = 200
            textboxColumn.Multiline = True
            Me.RadGridView1.Columns.Move(textboxColumn.Index, 1)
