cs后台代码修改GRIDVIEW模板控件属性

Question

各位高手，小弟请教一个问题：
asp.net 页面中有个Gridview控件。其中有一列是利用Templatefield模板绑定了3个Linkbutton按钮，我现在要在CS后台代码中去改变3个Linkbutton的Enabled属性，请问我该怎么写，我的写法是
Linkbutton lbt = (LinkButton)Gridview1.TemplateControl.FindControl("Linkbutton1");
      lbt.Enabled = true;
但是会报未实例化的错误，我有调试过，lbt的到的是null值。请高手赐教！

Answer 1

好像是Linkbutton lbt = Gridview1.row[i].cell[j].FindControl("Linkbutton1");

Answer 2

这样
    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        foreach (GridViewRow  gvr in GridView1.Rows)
        {
            Linkbutton lbt = (LinkButton)gvr.FindControl("Linkbutton1");
            lbt.Enabled = true; 
        }
    }

Answer 3

Linkbutton lbtn = Gridview1.row[i].cell[j].FindControl("Linkbutton1") as Linkbutton ;

Answer 4

调试这里：
Linkbutton lbtn = Gridview1.row[i].cell[j].FindControl("Linkbutton1") as Linkbutton ;

                    break;
                case "03":
                    ImageMap1.Enabled = true;

Answer 8

for (int f = 0; f < dt.Tables[0].Rows.Count; f++)
        {
            string functid = dt.Tables[0].Rows[f][0].ToString().Trim();
            switch (functid)
            {
                case "01":
                    imgmp1.Visible = true;
                    break;
                case "02":
                    LinkButton lbt = (LinkButton)gvdate.Rows[f].Cells[1].FindControl("lbtupdate");//cell[1]這里的1改成你自己對應的列
                    lbt.Enabled = false;
                    break;
                case "03":
                    ImageMap1.Enabled = true;
                    LinkButton lbt1 = (LinkButton)gvdate.Rows[f].Cells[1].FindControl("lbtdelete");//cell[1]這里的2改成你自己對應的列
                    lbt1.Enabled = false;
                    break;
                default:
                    break;
            }
        }
这下就对了，是吧是跟9L的有点像，确实是，就是把  那个2改为1就行了，三个linkButton都在同一列故是用Cell[1]
