ultrawebgrid hangs with updatepanel ajax
posted

hello.. I am having a problem with an ultrawebgrid,  updategrid and ajax control. The application works.. it just hangs for a super long time and grabs 50% of the users cpu. when i run without the ajax control, it runs fine.

I am using the following syntax

<asp:UpdateProgress DisplayAfter="500" ID="updateprogress1" runat="server">
<ProgressTemplate>
<div class="upg" style="left: 145px; top: 56px">
<center>
<asp:Image ID="Image1" runat="server" ImageUrl="~/Images/throbber-slow.gif" />
<br />
Update in progress...
<br />
</center>
</div>
</ProgressTemplate>
</
asp:UpdateProgress>

<asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Conditional" runat="server">
<ContentTemplate>
<asp:Button ID="BtnShowHide" runat="server" Text="Deliveries" Visible="true" />
<
br />
<asp:Panel runat="server" ID ="pnlNumberDeliveryDates" Visible="False" CssClass="OKPanels" BackColor="White">
<asp:Label runat="server" ID="lblstatus" />
<asp:DropDownList Visible="false" ID="txtNumDeliveries" runat="server">
<asp:ListItem>1</asp:ListItem>
<asp:ListItem>2</asp:ListItem>
</asp:DropDownList>
<asp:Button ID="BtnSplit" runat="server" Text="Split Delivery" Visible="true" />&nbsp;&nbsp;
<asp:Button ID="btnCancel" runat="server" Text="Cancel" />
</asp:Panel>
</ContentTemplate>
</asp:UpdatePanel>

<asp:UpdatePanel runat="server" UpdateMode="always">
<ContentTemplate>
<igtbl:ultrawebgrid>
</igtbl:ultrawebgrid>
</contentTemplate>
</asp:updatePanel>

like i say.. it is 'working' just not in any way that I would put out to the public. any ideas why??
