On my page I have an AJAXUploader and a few ListBox controls.
The ListBox Controls are in their own AJAX update panels.
When the AJAXUploader is present on the page, the ListBox controls force a full post back when the selected index is changed. When the AJAXUploader is not preset the ListBox controls do a partial page update as expected. I have the AutoPostBack = True of the ListBox. The uploader is not located in the ListBox’s UpdatePanel.
//Uploader
<eo:AJAXUploader ID="AJAXUploader1" runat="server" TempFileLocation="~/ul_temp" Width="250px">
</eo:AJAXUploader>
//UpdatePanel
<asp:UpdatePanel ID="UpdatePanel3" runat="server">
<ContentTemplate>
<asp:ListBox ID="ListBox1" runat="server" AutoPostBack="True" OnSelectedIndexChanged="ListBox1_SelectedIndexChanged">
<asp:ListItem>Test1</asp:ListItem>
<asp:ListItem>Test2</asp:ListItem>
<asp:ListItem>Test3</asp:ListItem>
<asp:ListItem>Test4</asp:ListItem>
</asp:ListBox><br />
<br />
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label><br />
</ContentTemplate>
</asp:UpdatePanel>
Any Ideas?
