在asp.net中設置gridview列無法使用

Question

我需要設置gridview列無法使用。 我也試過（（BoundField）gridView1.Columns [columnIndex]）。ReadOnly = true; 但它給出了無效索引的錯誤。 我不知道在哪里使用它。 我在rowediting方法中使用它。

protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
    {
        OleDbConnection conn;
        OleDbCommand cmd = new OleDbCommand();
        string path = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\website.mdb;Persist Security Info=False";
        conn = new OleDbConnection(path);
        conn.Open();
        cmd.Connection = conn;
        cmd.CommandText = "select [email],[password] from users";
        OleDbDataAdapter da = new OleDbDataAdapter(cmd);
        DataSet ds = new DataSet();
        da.Fill(ds);
        GridView1.DataSource = ds;
        GridView1.DataBind();
        conn.Close();
        GridView1.EditIndex = e.NewEditIndex;
        GridView1.DataBind();
    }

更新代碼：ASPX

<asp:GridView ID="GridView1" runat="server" AllowPaging="True" BackColor="LightGoldenrodYellow" BorderColor="Tan" BorderWidth="1px" Caption="User Info" CaptionAlign="Top" CellPadding="2" Font-Bold="True" ForeColor="Black" GridLines="None" ShowHeader="False" UseAccessibleHeader="False" Width="573px" AutoGenerateDeleteButton="True" AutoGenerateEditButton="True" OnRowCancelingEdit="GridView1_RowCancelingEdit" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing" OnRowUpdating="GridView1_RowUpdating"></asp:GridView>

試試這樣： -

GridView1.Columns["ColumnName"].ReadOnly = true;
