如何找到gridview中itemplate中的控件

[nicejaywin]

1.同一itemplate中有一button和一label
点击button,会在处理函数中读娶同一itemplate中的label
如何实现？

2.asp.net中有很多名字容器，组成一棵树，给一个控件，如何找到该控件的最接近他的上层名字容器（就是直接名字容器）

[qizhicong2]

应该是上层控件，而不是上层名字容器吧

[cpp2017]

 <ItemTemplate>
            <asp:Button ID="btn1" runat="server" Text="点击" CommandName="a" CommandArgument='<%#((GridViewRow)Container).RowIndex%>' />
           <asp:Label ID="l1"  runat="server"></asp:Label>
        </ItemTemplate>

    protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            GridViewRow row = this.GridView1.Rows[int.Parse(e.CommandArgument.ToString())];
            Label lbl =(Label)row.FindControl("l1");
            lbl.Text = "AAA";
        }

2. Parent

[nicejaywin]

对于2,您的回答是parent,parent应该是上层控件，而不是上层名字容器吧
因为只有page,gridview,等少数几个实现了 INamingContainer interface才是名字容器

[cpp2017]

还是刚才那个


protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
GridViewRow row = this.GridView1.Rows[int.Parse(e.CommandArgument.ToString())];
Label lbl =(Label)row.FindControl("l1");
lbl.Text = "AAA";

Control c = lbl.Parent;
while (c != null)
{
if (c is INamingContainer)
{
Response.Write(c.GetType().ToString()+","+c.ID+"***<BR>");
// break;
}

c = c.Parent;
}
}
