I have a WebImageViewer control inside of a WARP panel inside of a splitter pane.  I have the image viewer wired to handle the OnSelectedIndexChanged event, but when this event fires the images are removed from the viewer.  Is there some setting I need to set on the image viewer to allow it to persist the image data between async postbacks?

Here is the markup:

<

ig:WebSplitter ID="split_PageLayout" runat="server" Width="995px" Height="476px">

<Panes>

<ig:SplitterPane runat="server" BackColor="White" Size="250px" CollapsedDirection="NextPane">

<Template>

</Template>

</ig:SplitterPane>

<ig:SplitterPane runat="server" BackColor="White" Size="750px">

<Template>

<igmisc:WebAsyncRefreshPanel ID="pnl_Files" runat="server" LinkedRefreshControlID="pnl_Folders">

<ig:WebImageViewer ID="ivw_GalleryThumbViewer" runat="server" Width="100%" ScrollAnimations-Type="NextItem" OnSelectedIndexChanged="ivw_GalleryThumbViewer_SelectedIndexChanged">

</ig:WebImageViewer>

</igmisc:WebAsyncRefreshPanel>

</Template>

</ig:SplitterPane>

</Panes>

</ig:WebSplitter>

Here is the code behind:

protected

void Page_Load(object sender, EventArgs e)

{

// Load ImageItems into Image Viewer using custom Data Access Layer

protected

void ivw_GalleryThumbViewer_SelectedIndexChanged(object sender, ImageItemEventArgs e) {  }
