推荐答案

您好，我将使用网格的RowDataBound方法.分析数据，然后根据需要禁用控件.

网格代码:

Hi, i would use the RowDataBound method of the grid. Analize your data and then disable the control as you wish.

Grid Code:

<asp:gridview id="GridView1" runat="server" xmlns:asp="#unknown">
           onrowdatabound="GridView1_RowDataBound">
           <columns>
               <asp:boundfield datafield="Name" headertext="Name" />
               <asp:commandfield showeditbutton="True" />
           </columns>
       </asp:gridview>

背后的代码

Code Behind

protected void Page_Load(object sender, EventArgs e)
        {
//Fill th DataSource

            DataTable tbl = new DataTable("data");
            tbl.Columns.Add("Name");
            DataRow row = tbl.NewRow();
            row["Name"] = "Luis";
            DataRow row2 = tbl.NewRow();
            row2["Name"] = "Carl";
            
            tbl.Rows.Add(row);
            tbl.Rows.Add(row2);

//Bind the grid
            this.GridView1.DataSource = tbl;
            this.GridView1.DataBind();
        }

        protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
//Disable the control
                if (((System.Data.DataRowView)(e.Row.DataItem)).Row[0].Equals("Luis"))
                {
                    ((WebControl)((System.Web.UI.WebControls.TableRow)(e.Row)).Cells[1].Controls[0]).Enabled = false;
                    
                }
            }
        }

希望对您有帮助.问候.
