AJAX :: Behind The Scenes Of ScriptManager Control
May 30, 2010
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 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 am reading about "Registering Client Scripts with the ScriptManager Control". But I am not getting what means by registering the script with ScriptManager? What we get by registering the client script with ScriptManager?
I want to basically run an url which i would be generating behind the scenes without actually displaying it in browser to user...i guess i could use HTTPWebRequest or maybe something similiar to curl?...but i need to really just basically visit/run the generated url? how can i do that ?
How do I output/log the sql being executed behind the scenes by the Entity Framework in an asp .net mvc application? In my case I'm using a Sql Server 2005 database.
I found this question Linq to Sql logging, but I'm trying to figure out how to do this with the entity framework v1 and asp .net mvc 1.0.
Maybe this is not the best title to it, but this is what I am trying to find out. I need a way to construct a control in ASP.Net that mimics the ScriptManager in that it should look like this:
[code]....
How to make the Control have a List of items that you can add items to from the Source of a page.
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
add scriptmanager in all the page's involving MasterPage? add ScriptManager or ToolScriptManager in Master Page ? add toolscriptmanager in masterpage and rest of page's using ajax controls and update panel
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 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.
Is it possible to put a ScriptManager Control in a Content Page?I've tried inserting a ScriptManager, UpdatePanel, and ContentTemplate within the ContentPlaceHolder1 of one of my pages and it's not working.
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:
Error: $get("id of ToolkitScriptManager_hiddenfield") is null Source File: https://localtest.dk/layouts/site.aspx?_tsm_hiddenfield_=sitesscriptmanager_hiddenfield&_tsm_combinedscripts_=%3b%3bajaxcontroltoolkit%2c+version%3d3.5.40412.0%2c+culture%3dneutral%2c+publickeytoken%3d28f01b0e84b6d53e%3aen-us%3a1547e793-5b7e-48fe-8490-03a375b13a33%3a475a4ef5%3aeffe2a26%3a1d3ed089%3a5546a2b%3a497ef277%3aa43b07eb%3a751cdd15%3adfad98a5%3a3cf12cf1%3ad2e10b12%3af3d989c9 Line: 48
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.
Now i have added modal popup. Used ajax 15.1 toolkit. they said it doesnt require ajax script manager now.)
When i use it without ajaxscript manager it doesnt work. But when i use ajaxscript manager it works. But then i cant use scriptmanager (as two instance cant run).If i dont use script manager update panel wont work. Also i dont dont have any master page.
