Hi,

I have used popup control extender (Ajax tool kit 1.0) in user control.  I want to get the data using the popup control extender from database.

I have used the same process in aspx page its working perfectly.  But, User control can shows  an error. 

Error rendering control - update panel.

An unhandled exception has occured

The control with ID 'Poppuexe' requires a scriptManager on the page.

The codes in ascx

 <%@ Control Language="VB" AutoEventWireup="false" CodeFile="UserControl.ascx.vb"
    Inherits="Controls_UserControl" %>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
    <ContentTemplate>
        <asp:Label ID="LinkButton1" runat="server" Text="Click"></asp:Label>
        <ajaxToolkit:PopupControlExtender ID="PoppuExe" runat="server" DynamicContextKey='<%# Eval("PropertyId")  %>'
            DynamicServiceMethod="callfun" TargetControlID="LinkButton1" DynamicControlID="Panel1"
            PopupControlID="Panel1" Position="Bottom">
        </ajaxToolkit:PopupControlExtender>
        <asp:Panel ID="Panel1" runat="server" Width="250px">

Any one can help me.

And you get this error even with the ScriptManager declared in your ascx?

Do you have a script manager also in your Page? Then you need to use a ScriptManagerProxy in your ascx as there can be only one ScriptManager in the page.

See http://www.asp.net/AJAX/Documentation/Live/mref/T_System_Web_UI_ScriptManagerProxy.aspx

Now I have used the script manager in aspx page only and  set the ScriptManagerProxy in User control. Now I faced a problem.

It shows web service called failed error.

pl. help.

Hi Subbarayan,

From your description, I understand that you would like to use the DynamicServiceMethod to transform the PopupPanel into a table which is tied to the DataBase.The issue is web service call failed. If I have misunderstood you, please let me know.

I have tested your code locally and found out the cause is the DynamicServiceMethod is placed at the inappropriate file.

When your behavior implementation makes a base method call to the "populate" function, the relevant page content will be dynamically updated by the DynamicPopulate control. Population can be done with a page method or a web service and works just as it does when using DynamicPopulate directly. The DynamicServicePath property should be left null if ServiceMethod refers to a page method. So, we need to place the DynamicServiceMethod into some page or web service’s code-behind file. Meanwhile, set the DynamicServicePath with the relational file’s name.

For example: 

        <ajaxToolkit:PopupControlExtender ID="PoppuExe" runat="server" DynamicContextKey='123'
            DynamicServiceMethod="callfun" TargetControlID="LinkButton1" DynamicControlID="Panel1"
            PopupControlID="Panel1" Position="Bottom" DynamicServicePath="/Default.aspx">
        </ajaxToolkit:PopupControlExtender>

I had tried with many ways as your code to solve the problem. But not possible.  Pl.  help to use with usercontrol.
