[Solved] RadListView ItemDataBound Firing Every Other Item

[Seth]

I am having a problem with a RadListView.  I am binding the listview on the NeedDataSource event.  For some reason, the ItemDataBound event only fires every other item.  The listview is in an ItemTemplate of a RadPanelBar.  I am attaching these 2 events at runtime.

        <telerik:RadPanelItem Text="Contacts" Expanded="true" runat="server">
            <Items>
                <telerik:RadPanelItem>
                    <ItemTemplate>
                        <!-- Contact List -->
                        <div id="zonePartyContacts" style="padding:5px">
                            <telerik:RadListView ID="rlvContacts" runat="server" ClientDataKeyNames="NameAddrCode" DataKeyNames="NameAddrCode" AllowPaging="true" >
                                <LayoutTemplate>
                                    <div>
                                        <table cellpadding="0" cellspacing="0" style="padding-top:10px; padding-bottom:5px">
                                            <tr valign="top">
                                                <td id="itemPlaceholder" runat="server">
                                                </td>
                                            </tr>
                                        </table>

Seth,

You are missing check if item's type is RadListViewItemType.AlternatingItem too in the ItemDataBound's if statement.

If e.Item.ItemType = RadListViewItemType.DataItem Or e.Item.ItemType = RadListViewItemType.AlternatingItem Then

All the best,
