如何在datadridview中创建类型密码列

问题描述

为什么会出现此错误？columnIndex中的错误

错误 -

System.Windows.Forms.DataGridViewEditingControlShowingEventArgs不包含ColumnIndex的定义，也没有扩展方法ColumnIndex接受可以找到System.Windows.Forms.DataGridViewEditingControlShowingEventArgs类型的第一个参数（你是否缺少using指令或程序集引用？）

why this error happening here?errors in columnIndex
Error -
System.Windows.Forms.DataGridViewEditingControlShowingEventArgs does not contain a definition for ColumnIndex and no extension method ColumnIndex accepting a first argument of type System.Windows.Forms.DataGridViewEditingControlShowingEventArgs could be found (are you missing a using directive or an assembly reference?)

private void dtvregister_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
       {

           if (e.ColumnIndex == 2)
           {
               TextBox tb = e.Control as TextBox;
               if (tb != null)
               {
                   tb.PasswordChar = '*';
               }
           }


       }

什么我试过了：



i创建了密码文本框，并将文本归档为使用系统密码..我需要在datagridview中隐藏密码字符，或者我需要在datagridview中加密，这可能吗？请给我解决方案..谢谢

What I have tried:
