I have a user control with both an UpdatePanel and a ScriptManager.
Some pages in the system have a ScriptManager of their own, and need to include the UserControl.
This throws the "You can only have 1 ScriptManager" exception.
If I remove UserControl's ScriptManager, I'll get 'UpdatePanel1 requires a Script Manager" exception.
I've tried to modify the UserControl to dynamically include it's own script manager if none exists. But all the methods I've used before involve adding a delegate to Page.OnInit-- which won't work, since the UserControl Init fires first.
Because the system designers here like making my life difficult, I can't create a MasterPage, or a BasePage for the system in inherit off of. I'd be stuck going to each page an adding a ScriptManager before the UserControl on each of them. Is there any way of, in the UserControl, detecting if the page has a ScriptManager, and if not, adding it dynamically in a way that makes the UpdatePanel happy?
I'm finding that the scriptmanager and the updatepanel and basic implementations of AJAX for ASP.NET. I'm just wondering whether these were required to use AJAX and partial page update and referencing handlers such as button1_click on the server code page ?
Also if i can ask another question, I'm also wanting to know whether the updatepanel can support feed-in like facebook ? What I'm wanting to do is have something that updates the screen (like the update panel), and items within this panel contains links. When the user clicks on the link it shows a modal div, giving the user options to do some updates. Once the user clicks submit, then this makes a call to the server to update the details then also update the panel. Within the panel I also want to move some of the div elements using javascript (causing the drag and drops to save to the database).
i am using an updatepanel and loading diffrent user controls(.'ascx') in to it by the server side.
in every user control i have diffrent controls, max 4 controls in one user control.
no matter what control i am using when ever i cause an event from any control on the user control
the page postback twice and the item/option/text ichoose or checked or wrote in the control disappers, and the control
that caused the event returns the his original position like no change was made to it.
does anybody have any ideas or have a suggestion what causes thes double postback.
I have a page with a ScriptManager / UpdatePanel. I currently need to PostBack to a https page from an http page (different ports). I also need the same session data. Currently, I copy my form to a new form, and when I postback to my new Target on a new Port, I get a crash in xmlHttp..something. I will have to post more details later.
I'm currently wondering if this is possible. And does anyone know of such a fix. I even tried to Turn off Partial Rendering and I still get crashes. I can't do this until I pull out the scriptManager / UpdatePanel.
What scriptmanager control and
updatepanel control role if we add this control to web page
and when we use triggers with update panel control.
I'm using a Master Page with two content areas to render a two-column format.In the left column (Content ID="Left") I have an UpdatePanel (ID="ChoosePanel") with a TreeView control whose ID is "StickTree".In the right column (Content ID="Right") I have another UpdatePanel (ID="ChartPanel") with UpdateMode="Conditional" and the following trigger:
<Triggers>
<asp:AsyncPostBackTrigger ControlID="StickTree" EventName="SelectedNodeChanged" />
</Triggers>
There should be no problem having the trigger in a different UpdatePanel, but I'm getting the following exception when I run the page:A control with ID 'StickTree' could not be found for the trigger in UpdatePanel 'ChartPanel'.
I have a small website that uses 1 masterpage and several content pages. I'm able to insert a <ScriptManager> onto my content pages (just a couple of them). However, when I try to insert the <UpdatePanel>, it won't take it. I tried to wrap the <UpdatePanel> around a <Div> and it didn't like that, so then I tried wrapping the <UpdatePanel> around the actual textbox and it didn't like that. Below is some sample code.
Code:
<%@ Page Title="" Language="vb" AutoEventWireup="false" MasterPageFile="~/Site1.Master" CodeBehind="Profile.aspx.vb" Inherits="PF.Profile" %>
<asp:Content ID="Content3" ContentPlaceHolderID="contentProfile" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<div class="ProfileDIV" style="width: 48%;">
[Code]....
How can I incorporate the <ScriptManager>/<UpdatePanel> onto my content pages?
We have a ASP.NEt 4.0 project i just started. For some reason the ScriptManager, UpdatePanel and ListView controls have 0 intellisense, give me element not found errors and are really starting to $@#% me off. in 3.5 everything works fine. BUt in 4.0 none of these controls work (although they all exist in the toolbox). I do NOT have any Ajaxcontrol Toolkits installed for any previous version of ASp.NEt. I DO have the proper System.Web.Extensions dll referenced and it does exist.
My web.config is TINY though (is this new to 4.0?) i noted that in my compilation tag all i have is :
<
compilation
debug="true"
targetFramework="4.0"
/>
wheres in 3.5 in this were loads of references to the assemblies. Do i need this? I uninstalled and re=installed VS 2010 2 tiems today and its still the same.
We are currently migrating the client part of a legacy webapp from asp.net ajax to jquery/jquery-ui. The app consists (among other things) of some asp.net ajax UpdatePanels.
Now I want to throw out all that __doPostback() stuff and talk with jQuery's $.ajax to the "server-side" of the .ascx controls. Ideally, the server reponds with some parseable Datastructure that I can throw into my jQuery UI controls.
I already realized that this is difficult to do, because the asp.net ajax client/server code is heavily interwoven and there are no public interfaces to hook into ajax requests or responses. However, we don't want to change the server-side code, because it should still run with the old asp.net frontend.
After some tweaking I found out that I can hook into ScriptManager's beforeRequest and endRequest events to get notified of postbacks and partial responses. I dispatch these to jQuery Events:
var paqeRequestInst = window.Sys.WebForms.PageRequestManager.getInstance();
//bind ASP.NET ScriptManager events to jQuery events
paqeRequestInst._events.addHandler('beforeRequest', function(){
$(window).trigger('beforePanelResponse');
});
paqeRequestInst._events.addHandler('endRequest', function(pageRequestInst, ErrInst){
$(window).trigger('afterPanelResponse', [pageRequestInst, ErrInst]);
});
However, a lot of questions remain:
What is the best way to intercept the ScriptManager Response, parse it, and throw it into my jQuery UI controls? How do I update all that __VIEWSTATE stuff, that is normally managed by the ScriptManager?
Are there best-practices/jquery-plugins for such a "asp.net ajax to jquery" scenario?
I have a LinkButton inside an UpdatePanel that I do not want the client to click more than once before the UpdatePanel refreshes its contents. Right now the link button initiates a partial postback for every client side click until the update panel has time to refresh. This particular link fires off a very expensive process which I'd rather not have run unnecessarily. Is there a .NET standard way of doing this? Whats a good solution for this?
View 3 RepliesI have an app that uses masterpages. On the masterPages I have a TreeView. I would like to only refresh the ContentPlaceHolder & not the Entire masterPage when a link is clicked on the treeView.
I have placed the contentplaceholder in an Updatepanel. I would like to if possible avoid including the menu in the update panel.

I have a user control that needs a javascript function so I put my JS code in a variable and used the ScriptManager.RegisterStartupScript in Page_PreRender of the control as follows
StringBuilder jscode = new StringBuilder();
jscode.Append(@"<script language=javascript>");
jscode.AppendLine(@"function MyFunc(x) { {alert('hi'); }");
jscode.AppendLine(@"</script>");

I am currently using a asp.net 2.0 with visual studio 2005.
I am trying to build a web application using ajax.
but when I drag the ajax updatepanel on asp.net page it is not resizable,so how should i put other controls on it?
i am using a TabContainer and at each TabPanel i have embed an UpdatePanel in order to update each tab alone.
this is my code:
[Code]....
the problem is that it makes several seconds to update each tab (the same time for every tab) and i asume that this is happening because it updates all the TabContainer and not the selected Tab.
I need to that is this possible to add more than one scriptmanager tag in page. If i add, What error msg will come?
View 3 RepliesI have a form which I am using the RoundedCornersExtender, If I am using the ScriptManager control I am getting the following error-Error: AjaxControlToolkit requires ASP.NET Ajax 4.0 scripts. Ensure the correct version of the scripts are referenced. If you are using an ASP.NET ScriptManager, switch to the ToolkitScriptManager in AjaxControlToolkit.dll.I googled it and found that one way to overcome this is to use the ToolkitScripyManager, I replaced the ScriptManager with the ToolkitScriptManager and I dont get the above error anymore. On this same form I am using an UpdatePanel control but from some reason I am not getting a partial render but always a full page render.

I'm having a serious problem with my ASP.NET AJAX application.There is an javascript function in my application needs to be executed after the Timer_Tick event. Here's the code behind:

When I call the javascript function 'UpdateValue' for the first time(at onload page event), it works correctly. But after the Timer_Tick event, it does nothing. This is the HTML code:

What's the problem with the ScriptManager or the Timer_Tick event?
I am trying to update a listbox on the server from javascript using Ajax PageMethods. How would I reference the listbox control inside the Shared Sub, I get Error 156 Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class. The reason I want to do it this way is because when I updated it on the client the code-behind did not have the updated count.

I had this problem: I created a WebUserControl that used som Ajax stuff - hence it needed a ScriptManager.
The problem was that I couldn't add it to the WebUserControls html code (the .ascx file) since the WebUserControl sometimes was placed into a parent page that already had a ScriptManager, and I couldn't add a ScriptManagerProxy since the parent page sometimes didn't had a ScriptManager.
Alot of people just use a ScriptManager on the MasterPage, but this fails if: one doesn't use a MasterPage or one uses iFrames etc. that uses stand alone aspx pages, like Thickbox might do...
Here's the solution:
in the WebUserControls code behind (.cs file), put this:
protected override void OnInit(EventArgs e)
Can you tell me why its necessery to include "ToolkitScriptManager" or "scriptmanager" when we use AJAX ?
