要想?RowDataBound時(shí)間找到?EditItemTemplate里的控件，必須點(diǎn)擊編輯按鈕執(zhí)行??

protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
??????? {
??????????? GridView1.EditIndex = e.NewEditIndex;
??????????? LoadData();//此時(shí)綁定數(shù)據(jù)源時(shí)?RowDataBound事件函數(shù)能找到你的控件。
??????????? }

?private void LoadData()
??????? {
??????????? GridView1.DataSource = GridViewClass.ReadData();
??????????? GridView1.DataBind();
??????? }

??????? protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
??????? {
??????????? GridView1.EditIndex = -1;
??????????? LoadData();
??????? }

??????? protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
??????? {
??????????? if (e.Row.RowType == DataControlRowType.DataRow)
??????????? {

????????????? //要想找到控件必須點(diǎn)擊EDIT按鈕重新綁定DataSource

???????????? ? TextBox txt = (TextBox)e.Row.FindControl("TextBox1");
??????????????? if (txt != null)
??????????????? {
??????????????????? txt.Text ="ggggg";
??????????????? }
??????????? }
??????? }
