hi I'm having a problem with "Updateprogress" in ASP.NET . If i set the PostBackTrigger the progress loading image is not displayed but if i exclude the PostBackTrigger it's working. The code is as follows :
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<Triggers>
<asp:PostBackTrigger ControlID="Submit" />
</Triggers>
<ContentTemplate>
<asp:FileUpload runat="server" ID="Up"></asp:FileUpload>
<asp:Button runat="server" Text="Upload" ID="Submit" OnClick="Submit_Click" CausesValidation="false" />
<asp:UpdateProgress ID="upd" runat="server">
<ProgressTemplate>
<img alt="Checking Status" src="ajax-loader(2).gif" />
<%--<asp:Image runat="server" ImageUrl="~/ajax-loader(2).gif" ID="img" />--%>
</ProgressTemplate>
</asp:UpdateProgress>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
</body>

I cannot get the update progress to work at all, here is my code:
<asp:ScriptManager runat="server"></asp:ScriptManager>
<asp:UpdateProgress ID="updProgress" AssociatedUpdatePanelID="myUpdatePanel" runat="server">
<ProgressTemplate>
<div class=".uk-icon-spin"></div> Processing...
</ProgressTemplate>
</asp:UpdateProgress>
<asp:UpdatePanel runat="server" ID="myUpdatePanel">
<ContentTemplate>
<asp:Label ID="Label1" runat="server" Text="Panel created."></asp:Label><br />
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Create Instance" />
</ContentTemplate>
</asp:UpdatePanel>
Does anyone know what could be causing it? Thanks
I have this code:
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:Timer ID="Timer1" runat="server" Interval="1000" OnTick="TickEvent"></asp:Timer>
<asp:UpdateProgress ID="UpdateProgress1" runat="server">

But when I run the page, the time doesn't update and the progresspanel doesn't show. Can any one help?
I solved it by recopying all the scripts files to Scripts folder

You should have trigger in UpdatePanel like this:
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click" />
</Triggers>
Try to use asp:Image:
<ProgressTemplate>
<asp:Image ID="loader" runat="server" ImageUrl="~/img/loader.gif" />
</ProgressTemplate>
I'm trying to use a modal popup extender on my page so when I click a button, it must show a panel. Here is what I have:
<asp:UpdatePanel runat="server" ID="updPanel">
<ContentTemplate>
<ajaxToolkit:ModalPopupExtender ID="mpeEmailComplete" runat="server" TargetControlID="btnTesting"
PopupControlID="pnl" OkControlID="btnOk"
BackgroundCssClass="modalBackground">
</ajaxToolkit:ModalPopupExtender>
<asp:Panel ID="pnl" runat="server" style="display:none;">
<asp:UpdatePanel ID="udp" runat="server">
<ContentTemplate>
<asp:Panel runat="server" ID="pnlEmailComplete" Visible="false">
<asp:Label runat="server" ID="lblTest" Text="Testing testing testing"></asp:Label>
<asp:Button runat="server" ID="btnOk" Text="OK" />
</asp:Panel>
</ContentTemplate>
</asp:UpdatePanel>
</asp:Panel>
<asp:Button runat="server" ID="btnTesting" Text="Testing"/>
</ContentTemplate>
</asp:UpdatePanel>
but i can't get the panel to popup when the button is clicked. Anybody know why?
Your innermost panel has Visible=false.
<asp:Panel runat="server" ID="pnlEmailComplete" Visible="false"> *(change here)*
So, when you press the TESTING button, the ModalPopupExtender correctly causes the outer panel to display, but it's displaying an invisible inner panel, hence you see nothing on screen.
<asp:Panel ID="pnl" runat="server" style="display:none;"> *(this is ok)*
To fix, just yank the Visible=false from the outer panel (pnlEmailComplete)
Hope that helps!
Do you have any JavaScript errors and is pnl.Visible=False; set on the server-side anywhere?
Make sure you have the AjaxControlToolkit referenced properly, NuGet is the easiest way to add the reference.

Im using two update panels here, when i click "Button2" then "UpdatePanel2" was refreshed, if i click "Button1" then both update panel were refreshed, but my need is if i click "Button1" then "UpdatePanel1" have to be refreshed.
Thanks.
This behavior is by design. Because your UpdatePanel2 is nested inside of UpdatePanel1, when you refresh the contents of UpdatePanel1, this includes the child UpdatePanel.
If you want UpdatePanel2 to act separately from UpdatePanel1, you're going to have to take it out of UpdatePanel1 and make it a sibling, rather than a child.
