UpdatePanel & UpdateProgress

Hello, I've an updatepanel with a datalist, and an updateprogress with a gif animation. I need that when i do an asynchronous postback, the content of the updateprogress replace the whole content of the update panel. I don't know, how to do that... any idea please?

I'm waiting for your reply... thanks....

Give this approach a try:http://blogs.visoftinc.com/archive/2007/09/10/modalupateprogress.aspx

The update progress is displayed like that of a modal window like the AJAX modal popup displays (http://www.asp.net/AJAX/Control-Toolkit/Live/ModalPopup/ModalPopup.aspx).\

UpdatePanel + DataList (not updating)

I have a DataList inside of an UpdatePanel, with an update trigger from a drop down list. The DataList is data bound to a IDataReader upon postback. I'm not getting an update. When I remove the UpdatePanel, things work as expected. Here's the code:

<asp:Panel ID="pnlFilters" runat="server" style='margin: 0px auto 0px auto;text-align: center;'>
<asp:Label ID="lblProducts" runat="server" Text="Rovion Products:" />
<asp:DropDownList ID="ddlProducts" runat="server" style='margin-right: 50px;' OnSelectedIndexChanged='ddl_SelectedIndexChanged' AutoPostBack='true' />
<asp:Label ID="lblCategories" runat="server" Text="Vertical Categories:" />
<asp:DropDownList ID="ddlCategories" runat="server" OnSelectedIndexChanged="ddl_SelectedIndexChanged" AutoPostBack="true" />
</asp:Panel>
<br />
<br />
<atlas:UpdatePanel ID="upDemos" runat="server">
<ContentTemplate>
<atlas:UpdateProgress ID="uppDemos" runat="server">
<ProgressTemplate>
<asp:Panel id="pnlLoader" runat="server" style='margin: 0px auto 0px auto;text-align: center;'>
<asp:Image ID="imgLoader" runat="server" ImageUrl="~/Images/ajax-loader.gif" />
</asp:Panel>
<br />
</ProgressTemplate>
</atlas:UpdateProgress>
<asp:DataList ID="dlDemos" runat="server" CellPadding="10" GridLines="None" RepeatColumns="3" ShowFooter="False" ShowHeader="False" BorderColor="#89a3b2" BorderWidth="2px" style='margin: 0px auto 0px auto;text-align: center;'>
<ItemTemplate>
<asp:HyperLink ID="hlThumbnail" runat="server" ImageUrl='<%# Eval("ThumbnailURL") %>' NavigateUrl='<%# GetNavigateUrl() %>' Target="_new" />
<br />
<br />
<b>Title:</b> <%# Eval("Title") %>
<br />
<b>Product:</b> <%# Eval("ProductName") %>
<br />
<b>Vertical:</b> <%# Eval("CategoryName") %>
</ItemTemplate>
</asp:DataList>
</ContentTemplate>
<Triggers>
<atlas:ControlValueTrigger ControlID="ddlCategories" PropertyName="SelectedValue" />
<atlas:ControlValueTrigger ControlID="ddlProducts" PropertyName="SelectedValue" />
</Triggers>
</atlas:UpdatePanel>

Any suggestions? Thanks! :-)

I really need some advice on this problem. I have a ScriptManager w/ partial rendering enabled. What happens is the UpdateProgress graphic will show up when I change the selection of the drop down list (like it's posting back), but 1) the UpdateProgress never goes away, and 2) the DataList is never updated...so everything in the UpdatePanel is not being updated, and I don't know why :-(

Does anyone have a clue why this would be occurring? Thanks for your time!

Hi~This might be the explanation of your problem. You may try event trigger other than value trigger, e.g

<atlas:ControlEventTriggerControlID="ddlCategories"EventName="SelectedIndexChanged"/>

UpdatePanel and "foreign" characters

Hi!

I'm using an UpdatePanel with a DataList inside and a Trigger that updates the panel.

In Explorer no updates are shown if the datalist contains swedish characters ( ?, ? or ?), the trigger works but the "old" content is still shown. This works perfectly fine in FireFox.

Any suggestions?

I tried to simulate this and it appears to be working okay. What I did was have both FormView and DataList for a table within the same UpdatePanel. I've also handled the ItemUpdated event for the FormView and invoked DataList.DataBind() method to refresh the DataList content. Using your swedish characters for one of the FormView updates, it gets reflected to the DataList. I'm using IE version 6.0.
