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:
[Code]....
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:
[Code]....
What's the problem with the ScriptManager or the Timer_Tick event?
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 searching for an example with an client timer that ticks synchronous with an server timer. Also there must be a button on the client side which can reset the server timer to an default value, and with this it also resets the client timer ofcourse. I tried it myself but it seems that there is some postback delay which makes it impossible for me to make it atleast look like it goes synchronous.
I hope somebody got an example for me, the button part is really important because by pressing that button the delay comes.
VS2010 ( Vb.net ).I have a masterpage that contains a gridview, giving stats and information on client files sent to us. This gridview is updated by means of a timer control every 10 seconds. In my grid I have an image field, to display either a tick .. if everything is ok or a cross for any problems.When the timer control timer event forces a gridview databind every 10 seconds.When the page first loads, i get the default red Cross in the gridview imagefield, however when the timer loops forces a 'databind' I lose the redCross and it is replaced with the default image control ( as if no url is set ) . Then I get a server 404 error.I am using the OnDataBound event to fire my vb sub. I have commented out evertything just to get a solid starting point but im still getting errors.
I have an ASP.NET form with several update panels. All works great.I use a timer and have it handle some periodic upates. That works correctly too. However, I appear to get an error when I leave the page open running in the debugger. Specifically the above JScript error 12030.I'm not clear how to find the source but I assume it is because my page has logged out. If I refresh I go back to my login page.So, does this sound like the cause? If so, how to I address this?
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
I 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.
Currently using Framework3.5 Ajax Dll-3.5 Pages included -MasterPage and 6-Default Page's myquery i m currently using Different Designing Interace for all the Default Page's means some of page's includes update panel and some not sly some page's include ajax toolkit tool's like -CascadingDropDown,UpdatePanel and Masked Edit Control do i need to

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:
I just downloaded the latest (3.5.40412.0) version of Ajax Control Toolkit and in order to update the existing version, I have replaced <asp:ScriptManager with <ajaxtoolkit:ToolkitScriptManager. The page loads with an javascript error:

Can anybody explain why cant you have more than one scriptmanager control in a page. Why gets emitted in the markup which creates a problem with two scriptmanager control on the page.
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 have to open Outlook using Mailto on Row_Command event of a gridview. I am using the following code on button click which is not working--
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "mailto", "<script type = 'text/javascript'>parent.location='mailto:abc.abc@abc.com?subject=hello&body=Happy New Year'</script>", true);
What is the difference between AjaxScriptManager control and ScriptManager control?
I have a folder AjaxCtrlToolKit4_0 on my computer. I try to follow the instruction from [URL] to add an Ajax extender control to a web page but cannot find the WebFormsRelease folder underneath this AjaxCtrlToolKit4_0 folder.
Various articles refer to the 4.0 ScriptManager (and Proxy) ClientElementsToActivate property.However I can't find it.Am I missing something really obvious?I'm on VS 2010.

I m using web user control for java script calendar when i use ScriptManager on aspx page then value of calendar input type is not showing without ScriptManager is showing..
I m using this code on Test.aspx page -
<uc1:CalendarUserControl ID="CalendarUserControl1" runat="server" OnLoad="CalendarUserControl1_Load"/> And I m using code on CalendarUserControl.ascx- <input type="text" name="showdia" id="showdia" size="9"/><input onclick="return showCalendar('showdia', 'mm/dd/yyyy');" type="image" src="images/cal.gif" name="reset" style="cursor:pointer"/> <input id="Button1" type="button" onclick="loadimages(showdia.value)" style="background-image: url(images/language/english/view.gif); width: 57px; height: 24px; background-color: transparent;"/> And code on Test.aspx.cs file - protected void Page_Load(object sender, EventArgs e) { string myscript1 = "document.getElementById('showdia').value='" + System.DateTime.Now.ToString("d") + "'"; ClientScript.RegisterStartupScript(typeof(Test.aspx), "myscript1", myscript1, true); } when I use ScriptManager then value of <input type="text" name="showdia" id="showdia" /> is not showing
i am using ScriptManager in my webpage. i am also using a lot of pagemethods in this page. When i look at the viewsource of the browser after the page has been rendered i find a lot of javascript which has been generated by the scriptmanager.
how can i browser cache all these scripts so that they are not loaded everytime the page is rendered.
As per Yahoo's guidelines for performance of web sites , javascripts should be combined in one to avoid extra http request , as i saw in YSlow asp.net loads 3 to 4 scripts one for MicrosoftAjax.js , one for microsoft MicrosoftAjaxForms.js & some other 2 which may tondle postbacks & client side validations , I want these 4 js to be in one.
