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">
<ProgressTemplate>
<img src="http://jimpunk.net/Loading/wp-content/uploads/loading18.gif" />
</ProgressTemplate>
</asp:UpdateProgress>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />
</Triggers>
<ContentTemplate>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
Codebehind code:
protected void TickEvent(object sender, EventArgs e)
{
Label1.Text = DateTime.Now.ToString();
}
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

I have this html that contains a UpdatePanel and a Button, I would like update my User Control(that have a UpdatePanel too) when Button click
I get this error: A control with ID 'btnSubmit' could not be found for the trigger in UpdatePanel when page load.
<asp:Content ID="Content1" ContentPlaceHolderID="content" runat="server">
<asp:UpdatePanel runat="server" ID="updatePanelMyUC" UpdateMode="Conditional" ChildrenAsTriggers="false">
<ContentTemplate>
<uc1:myUserControl runat="server" ID="myUserControlID"/>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnSubmit" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="rightcolumn" runat="server">
<asp:ImageButton ID="btnSubmit" ImageUrl="../../Resources/btnSubmit.png" runat="server" OnClick="btnSubmit_Click" />
</asp:Content>
Your btnSubmit is outside the UpdatePanel.
Trigger of the UpdatePanel must be inside the ContentTemplate of the said UpdatePanel.
<asp:Content ID="Content1" ContentPlaceHolderID="content" runat="server">
<asp:UpdatePanel runat="server" ID="updatePanelMyUC" UpdateMode="Conditional" ChildrenAsTriggers="false">
<ContentTemplate>
<uc1:myUserControl runat="server" ID="myUserControlID"/>
<asp:ImageButton ID="btnSubmit" ImageUrl="../../Resources/btnSubmit.png" runat="server" OnClick="btnSubmit_Click" />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnSubmit" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="rightcolumn" runat="server">

I am trying to learn how to use UpdatePanel And this is my code.The problem is everything is ok but I cant see Loading.gif image .when code excatues Its wisible aspx page .What am i missing out here
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />

<asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID="UpdatePanel1">
<ProgressTemplate>
<img src="load.gif" />
</ProgressTemplate>
</asp:UpdateProgress>
</div>
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>
Does anyone have a resource or provide a code sample on when not to display an UpdatePrgress Control when a certain button is clicked.
in your Markup:
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<fieldset>
<legend>UpdatePanel</legend>
<asp:Label ID="Label1" runat="server" Text="Initial page rendered."></asp:Label><br />
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
</fieldset>
</ContentTemplate>
</asp:UpdatePanel>
<asp:UpdateProgress ID="UpdateProgress1" runat="server">
<ProgressTemplate>
Processing...
</ProgressTemplate>
</asp:UpdateProgress>
in your code behind:
protected void Button1_Click(object sender, EventArgs e)
{
// Introducing delay for demonstration.
System.Threading.Thread.Sleep(3000);
Label1.Text = "Page refreshed at " +
DateTime.Now.ToString();
}
this should work, try it...
source: Introduction to the UpdateProgress Control
I Have a TextBox outside the UpdatePanel and a Button inside the Updatepanel When i click on the Button it show value in TextBox.
I Have Write Following Code.
<%# Register TagPrefix="AjaxToolKit" Assembly="AjaxControlToolkit"
Namespace="AjaxControlToolkit" %>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server"
EnablePageMethods="true" />
<asp:TextBox ID="TextBox5" runat="server" />
<asp:UpdatePanel runat="server" ID="Up1">
<ContentTemplate>
<asp:Button ID="btn" runat="server" onclick="btn_Click" />
</ContentTemplate>
</asp:UpdatePanel>
</asp:Content>
----------Code Behind---------
protected void btn_Click(object sender, EventArgs e)
{
TextBox5.Text = "20000";
}
Your textbox value can't be updated untill you put it in an update panel.
<ContentTemplate>
<asp:TextBox ID="TextBox5" runat="server" />
<asp:Button ID="btn" runat="server" onclick="btn_Click" />
</ContentTemplate>
OR, it would be better if you register a trigger of the button and pull your button out from your update, like...
<asp:UpdatePanel runat="server" ID="upnl" UpdateMode="Conditional" >
<ContentTemplate>
<asp:TextBox ID="TextBox5" runat="server" />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btn" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
