How can I get confirmbuttonextender using the AJAX toolkit to open a confirm window

See more:

I've included the ScriptManager to the page, then attached the ConfirmButtonExtender to a button click event. Everything shows up correctly in the properties of the button but no Confirm Window shows when the button is clicked. A white border shows around the button when the button is clicked, but no Confirm Window.

There is the Registration at the top of the ASP page:

HTML

<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="asp" %>

Then I added the ScriptManager:

ASP.NET

<asp:ScriptManager ID="ScriptManager" runat="server" EnablePageMethods="true">
</asp:ScriptManager>>

Here is the code:

ASP.NET

<asp:Button ID="btnGetSelectedReports" runat="server" 
    Text="Download Selected Report(s)" 
    OnClick="btnGetSelectedReports_Click" BackColor="#337AB7" 
    ForeColor="White" Width="500px" Height="36px" Font-Bold="True" 
    Font-Size="Medium" />      
<asp:ConfirmButtonExtender ID="btnGetSelectedReports_ConfirmButtonExtender" 
    runat="server" 
    BehaviorID="btnGetSelectedReports_ConfirmButtonExtender" 
    ConfirmText="The selected report(s) will be written to your folder. Do you wish to continue?" 
    TargetControlID="btnGetSelectedReports" 
    OnClientCancel="btnClearAll_Click()">
</asp:ConfirmButtonExtender>

In the web.config:

HTML

<controls>
    <add tagPrefix="ajaxtoolkit" namespace="AjaxControlToolkit" assembly="AjaxControlToolKit"/>
</controls>

Nothing seems to work, it always goes to the next page on a redirect and completes all steps prior to switching to the new page, bypassing a Confirm Window.

I would appreciate any help,

Jack

What I have tried:

I added and changed several ways of attaching the ConfirmButtonExtender.

I've added different lines to the web.config files.

I believe you missed adding ToolkitScriptManager

Quote[^]:
You must add a ToolkitScriptManager control to any page that contains Ajax Control Toolkit controls. The ToolkitScriptManager performs two main functions.

First, the ToolkitScriptManager handles dependency resolution. The ToolkitScriptManager is responsible for loading all of the JavaScript files required by a set of Ajax Control Toolkit controls.

Second, the ToolkitScriptManager is responsible for optimizing JavaScript and files. The ToolkitScriptManager combines, minifies, compresses and caches JavaScript files so that they can be delivered more efficiently to the browser.

So, try something like:

ASP.NET

<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="asp" %>
.
.
.
.
.
<span class="style1"><strong><span class="style2">Click on Submit Button and 
Confirm with OK Button</span></strong></span><br />
<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</asp:ToolkitScriptManager>
<br />
<asp:TextBox ID="TextBox1" runat="server" >Test data entered</asp:TextBox>
<br />
<asp:Button ID="Button1" runat="server" Text="Submit" onclick="Button1_Click" />

<asp:ConfirmButtonExtender ID="ConfirmButtonExtender1" runat="server" TargetControlID ="Button1" ConfirmText = "Are you want to submit?"></asp:ConfirmButtonExtender>
.
.
