如何在后台代码中的Repeater控件中获取对标签的引用

Question

<asp:repeater id="rpt" run="server">
<ItemTemplate>
<asp:LinkButton id="Delete" runat="server" OnCommand="Delete_Command"></asp:linkButton>
<asp:label id="lblMessage" run="server">
</ItemTemplate>
</asp:repeater>

Code Behind:

protected void Delete_Command(object sender, CommandEventArgument e)
{

}

How can I get a reference to the "lblMessage" in Delete_Command?

Answer 1

I would recommend reorganize your code a little bit, which will allow you to perform such operations easily using FindControl . Basically my suggestion boils down to handling Command event not of the link button, but of the repeater itself:

<asp:repeater id="rpt" run="server" OnItemCommand="rpt_ItemCommand">

Then access to item contents is extremely easy:

protected void rpt_ItemCommand(object sender, RepeaterCommandEventArgs e)
{
    Label label = e.Item.FindControl("lblMessage");
    LinkButton linkButton = e.Item.FindControl("Delete");
}

Answer 2

You can try this :

Page :

<asp:Repeater ID="rpt" runat="server" OnItemCommand="rpt_ItemCommand">
<ItemTemplate>
    <asp:LinkButton ID="Delete" runat="server" CommandName="Delete"></asp:LinkButton>
    <asp:Label ID="lblMessage" runat="server"/>
</ItemTemplate>

Code Behind :

protected void rpt_ItemCommand(object source, RepeaterCommandEventArgs e)
{
    if (e.CommandName == "Delete")
    {
        Label lblMessage = e.Item.FindControl("lblMessage") as Label;
    }
}
