意思是你想在Delete_Command事件中找到标签吗？
在aspx中
<asp:Repeater ID="rpt" runat="server">
<ItemTemplate>
<asp:LinkButton ID="Delete" runat="server" OnCommand="Delete_Command"></asp:LinkButton>
<asp:Label ID="lblMessage" run="server">
</ItemTemplate>
</asp:Repeater>在aspx.cs中
protected void Delete_Command(object sender, CommandEventArgs e)
{
foreach (RepeaterItem item in rpt.Items)
{
Label lblMessage = item.FindControl("lblMessage") as Label;
if (lblMessage != null)
{
lblMessage.Text = "";
}
}

如果您想以自己的方式实现，请使用下面的
protected void Repeater1_ItemCommand(object source, CommandEventArgs e)
{
(((LinkButton)source).NamingContainer).FindControl("lblName")
}另一种方法..但是你可以买到的东西
aspx
<asp:Repeater ID="Repeater1" runat="server"
onitemcommand="Repeater1_ItemCommand">
<ItemTemplate>
<asp:Label ID="lblName" runat="server" Text='<%=Eval("Name") %>' ></asp:Label>
<asp:LinkButton runat="server" CommandName="Delete_Command" Text="sd"></asp:LinkButton>
</ItemTemplate>
</asp:Repeater>.cs
protected void Delete_Command(object sender, CommandEventArgument e)
{
if(e.CommandName != null)// Conditional Check
{
Label label = e.Item.FindControl("lblMessage");
// do something with the label
}
