    I am trying to create a UserControl which will allow the user to dynamically add/remove "items" to the form. This control is dropped into a page through the Sitefinity Admin.  Below is my code for the repeater.

    <asp:Repeater ID="ItemRepeater" runat="server" EnableViewState="true">
            <div class="form-field" style="width:525px;">
                <div style="float:right;margin-right:15px;"><asp:LinkButton ID="ItemRemoveButton" runat="server" OnCommand="RemoveItem_Command" CommandArgument='<%# Container.ItemIndex %>' CommandName="Delete" Text="Remove Item" /> </div>
                <div>Item <%# Container.ItemIndex + 2 %></div>
                <div><asp:TextBox ID="ItemTextBox" runat="server" TextMode="MultiLine" Width="505" Height="100" class="item" Text='<%# Eval("Item") %>' /></div>
            <div class="form-field" style="width:60px;">
                <div>$<asp:TextBox ID="PriceTextBox" runat="server" Width="49" MaxLength="7" class="numeric" Text='<%# Eval("Price") %>' /></div>
    <div class="form-field full-width">
        <asp:Button ID="AddItemButton" runat="server" Text="+ Add Another Item" Width="130" OnClick="AddItemButton_Click" />
        <hr />

    When when trying to access the Repeater control on the back-end, the repeater has no items in it's collection.  I have tested this same code outside of Sitefinity and accessing the items on the back-end works just fine.

    Could anybody shed some light on this issue?  I have experienced it several times in the past with all dynamically generated controls and I would like to know whats going on.

    Hello Michael,

    "When when trying to access the Repeater control on the back-end, the repeater has no items in it's collection"

    How and where do you access the repeater? It is possible that it is too early and the data is still not populates. Could you try .to subscribe for ItemDataBound event and see when it is called and get the DataItem from there?

    Best wishes,
