推荐答案

两种方式:
1.在ASPX中，如果定义了列:

Two ways:
1. In ASPX if the columns are defined:

<asp:BoundField DataField="MyProperty" HeaderText="Int" InsertVisible="False" ReadOnly="True" />

2.在文件后面的代码中:
要使列在编辑时变为只读状态，请添加此

2. In code behind file:
To make the column readonly on editing add this

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
   // Find the column and set it readonly
   BoundField bound = GridView1.Columns[1] as BoundField;
   bound.InsertVisible = false;
   bound.ReadOnly = true;
}

通常，我们定义网格的列，选项1应该很好.

Generally, we define the columns of a grid and option 1 should do just fine.
