单击复合控件内的按钮时，不会触发Repeater ItemCommand

Question

I have a Repeater containing nested custom CompositeControl controls in the following way:

Wrapper

• Head
• Body

<asp:UpdatePanel ID="noteArea" UpdateMode="Conditional" ChildrenAsTriggers="false" runat="server" >
    <ContentTemplate>
        <asp:Repeater ID="noteRepeater" runat="server" EnableViewState="true" OnItemDataBound="noteRepeater_ItemDataBound" OnItemCommand="noteRepeater_ItemCommand">
            <ItemTemplate>
                <asp:Button runat="server" CommandName="edit" ID="testButton" />
                <easit:NoteControl ID="noteControl" runat="server" />
            </ItemTemplate>
        </asp:Repeater>
    </ContentTemplate>
</asp:UpdatePanel>

Head control contains two Buttons . When I click on either of them, the ItemCommand event of Repeater doesn't get invoked. If I move the buttons right to ItemTemplate , it works. But I need to keep them where they are.

What is the correct way to bubble them up the control hierarchy?

Answer 1

You can have the control throw an event which your page (with the repeater) can listen for. Any information you need for the event can be provided when initializing each control.

Answer 2

These controls are outside the ItemTemplate .. so they really can't trigger an ItemCommand.

An ItemCommand has specific attributes that will not be available to your buttons if they are outside the ItemTemplate (ItemIndex for instance, to determine the index of the clicked item)
