在DataGridView中,在添加新行时将列的ReadOnly属性设置为false,以更新其true(c#.net)

Question

我已将2个数据表列的readonly属性设置为true.

    List.Columns[0].ReadOnly = true;
    List.Columns[1].ReadOnly = true;

但我只希望它们只在用户尝试更新时才能读取,用户可以向dataGridView添加新行,所以我想在尝试添加新行时将readonly属性设置为false.我尝试在datagrid的CellDoubleClick事件上执行此操作,但它不会做任何事情,因为它是为了调用beginedit迟到.

if(e.RowIndex == GridView.Rows.Count-1)
                GridView.Rows[e.RowIndex].Cells[1].ReadOnly = GridView.Rows[e.RowIndex].Cells[0].ReadOnly = false;
            else
                GridView.Rows[e.RowIndex].Cells[1].ReadOnly = GridView.Rows[e.RowIndex].Cells[0].ReadOnly = true;

有任何想法吗

您必须使用cellbegin编辑将单元格readonly属性设置为true..

   private  void dataGridView1_CellBeginEdit(object sender,DataGridViewCellCancelEventArgs e)
   {
       if (dataGridView1.Columns[e.ColumnIndex].Name == "ColName0")
       {
           // you can check whether the read only property of that cell is false or not

       }
   }

我希望它会帮助你......
