Web Forms :: Use Scriptmanager With Existing Javascript?
Mar 11, 2010
I have an existing site having a bulk of javascript used on the page. Now the page has to convert in AJAX but while using update panel my controls are not able to use existing javascript
It is not feasible to use ScriptManager.RegisterClientScriptBlock because script is around 200 to 300 of lines and also not feasible to move it in another JS File and Use ScriptManager.RegisterClientScriptInclude since each page has different script with almost same numbers of line Is there any way so that i can use existing script with minimum number of steps with full reusability

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.

I have an application that uses various script files. These files are not used for any AJAX purposes. However, I am using MS AJAX Libraries. My goal is to use the ScriptManager to manage release and debug versions of my JavaScript. Is this the right approach? Is there a better way to handle this task?

In ASP.NET 4.0 RC2 the Menu Control by default emits Javascript like this:
[Code]....
There should be a feature coming up to disable this, but I think it's not in RC yet. At least it's not working for me.
Now, the problem is, that this Javascript kills my own Menu Javascript (I use an CSS Adapter). Is there a way to overwrite the stuff that comes from the Menu control? Can be a hack, just need something until this is fixed by MS.

I am successfully including a javascript resource by calling ScriptManager.RegisterClientScriptResource at the end of OnPreRender in my custom control. However, the resulting script tag is being included before the automatically included script tags that define things like Type and Sys which my script depends on. I thought they were defined in the order that they are included but I can't include my script any later then I am. How can I control the order in which the script tags are included?

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 have a jQuery function in a .js file, and the function requires a querystring parameter to be passed. If I try to use the CompositeScript feature in the ScriptManager, it pukes on the file that has the querystring.

I am opening a window with window.open and I am losing the server session. Is there a way to open a window with Javascript and use the same session? I need this working in IE 7 and higher. I am working with ASP.NET on the server side. The sever does not have a sessionless cookie state.

I am creating a custom control and had a thought before I began. My control relies on the jQuery library to work. What if the user already has a version of the library already on their page. Will this effect anything? If my version is newer / older and my control will only work with that version of the libaray, what should I do?

I use scriptmanager instead of toolscript manager and don't seem to have problems. But I have noticed that the recommendation is to use toolscriptmanager. Is there any difference now?

I have a asp .net page with an UpdatePanel. Inside that I have a dropdownlist and a button. In the On Page Load I populate the dropdownlist and have a value selected.On the button click even I register a clientscript something like this ScriptManager.RegisterClientScriptBlock(Page, this.GetType(), "Alert", "alert(hello')", true);Problem part:When I click on the button, the alert goes on, then I cannot select anything on the dropdownlist.

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.

I don't know if this is the correct place to post this, so, sorry if it's not.The reason for my issue is some functionality that is missing from an ajax toolkit component, but the problem itself have nothing to do with a toolkit issue, and that's why I'm not posting this on the toolkit forum.What do I need to do?
Since the masked edit extender dont support "keep the mask if the control is not empty" funcionality yet (which I can't understand why), I've been having a hard time on trying to do that by using javascript.What have I done?I've wrote a static method in a helper class that looks for every maskededitextender, gets the textbox related to that extender and adds onblur and onfocus events on them as shown below:
[Code]....
Ok, now, those 2 javascripts do the following:
[Code]....
And I'm calling that FixMaskClearIssue() on the masterpage's load event.Now, finally, the problem... the FixMaskOnLoad javascript function:
[Code]....
The code is not finished yet, so there may be some logic errors, but i just cant test it cuz it keeps telling me that there is an error in the "mask = $find(IDs[0]);" line...It says Object Expected. I've tryied to put the full path of that function (Sys.Application.findComponent) instead of the $find, and it says that he cant find Sys.
I need this javascript cuz the mask is now working flawlessly, except for one little detail: if the user refreshes the website by pressing F5, the not empty and masked fields keep the value but lose the mask, and i need to keep them there, so i thought to set ClearMaskOnLostFocus to false on the masks of those fields to make them appear again.Can anyone tell me why i cant use $find if running through a scriptmanager registration, but i can otherwise? it works fine on the two other javascripts above!

I'm trying to extend ScriptManager to simplify dealing with resources that have multiple resource files (e.g. more than one script file as well as css). The goal is that I will be able to add a single ScriptReference to Scripts and have it load more than one resource related to that reference name.
What I'm getting stuck on is, how does your basic ScriptManager know what to do with stuff when when using static methods that do not include a Page parameter? For example:
ScriptManager.ScriptResourceMapping.AddDefinition("someName", new
ScriptResourceDefinition { Path="/script/somescript.js"});
This adds a definition to (I guess) whatever the active script manager is for the page that's running when you call it. But unlike the old-school methods, like RegisterClientScriptBlock there is no parameter passed that identifies the page. But this stuff must get stored in the ScriptManager object, no? So how does it know?
I could always get a reference to the active one with this:
ScriptManager.GetCurrent(page);
but ideally, I would create new methods that work exactly like Microsoft's. I can't figure out how I could implement something like
ScriptManager.ScriptResourceMapping.AddDefinition(string name,
ScriptResourceDefinition definition,
ResourceType type)
that could figure out the object instance to add the stuff into without having to add a Page parameter.

I know I can load the symbols for the class but i can't get it to work. I tried everything so i give up.
I only need the code for this class. It's because i am using a custom script manager and i must know how the .net one works.

Is MVC ScriptManager still the current way to register JS specific to my .ASCX (partial view)?
[URL]
That is from last year before VS2010 release, so I wonder if there is a more prevalent way to do this?
It's also from before VS2010 release, so maybe there is now an "packaged" way to do this?

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.

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:
