How To Add Scripts To The Page (its CompositeScript) And The Page's ClientScript
Feb 21, 2011
My page loads scripts and css from some custom assembly. For now, I use the ScriptManager to add scripts to the page (its CompositeScript) and the page's ClientScript.GetWebResourceUrl() for css files. So, on the page(s) my scripts are referenced by /ScriptResource.axd and css are referenced by /WebResource.axd. Works fine except the fact that those URLs look really ugly. Is there any manageable way to replace those urls with my own fake paths without moving/hosting script/css physical files somewhere?
The problem i have noticed is that sometimes after a clientscript alert() the page will not post back properly and kind of "hang". The page will only show the background and will not do anything until the browser is refreshed.
[Code]....
I call clientscripts withing button click events, after the code has succeded or failed(try catch). So i will write to database/upload file/send email and then depending on the restult run a clientscript alert to notify the user. However sometimes after you "Ok" the alert the page does not finish posting back and "hangs" half loaded.
how to fix it? would adding return false; after the alert in the client script at all? (i have seen this in a online code example but they did not explain why they put it there).
I am new to .Net and webpart. What I try to do is to create a griedview webpart with a functionality of export to excel. The gridview also can drildown another gridview. The drilldown work as expected. When click export to excel link button it works ok, too. The problem is when comeing back to the gridview to click any row, it stops to drilldown. If I want to use export to excel link it stop working also. Only refresh page can make it work again. I did research and found a solution, that is, to implement a javascript to solve the problem. I follow references from microsoft site as shown below.
i want to call javascript function from codebehind using page.clientscript it is working fine if i am not using AJax's Updatepanel,but if i want to use Update panel, but the same time i want to call javascript function from codebehind
If you have too many javascript file includes with a compositescript in a script manager you get this error..."The resource URL cannot be longer than 1024 characters. If using a CompositeScriptReference, reduce the number of ScriptReferences it contains, or combine them into a single static file and set the Path property to the location of it."
I know how to fix this using a plane old asp:scriptmanager (use script manager proxies). But how do I fix it using a ToolkitScriptManager?
<ajaxToolkit:ToolkitScriptManager ID="GeneralScriptManager" CombineScripts="true" CombineScriptsHandlerUrl="Utility/CombineScriptsHandler.ashx" runat="server" AsyncPostBackTimeout="480" EnablePageMethods="true"> <CompositeScript> <Scripts> <asp:ScriptReference Path="JavaScript/jQuery/jquery-1.4.1.min.js" / ... A whole lot more script references here </Scripts> </CompositeScript> </ajaxToolkit:ToolkitScriptManager>
UpdateI've tried doing this with the script combiner included in the sample application. I think it's right, but I've been wrong plenty of times before... No luck though.Another update So, I thought that maybe if I included multiple CompositeScript blocks within the single ToolkitScriptManager it might create them all as separate files. Nope. Still get the same error. No one has any ideas? When I Google "toolkitscriptmanager cannot be longer than 1024 characters" this StackOverflow question is the number 1 result...
I'm having a problem trying to combine the ScriptResource.axd files automatically generated by Ajax using ScriptManager's CompositeScript property....on some pages there's 15 of these files, so I'd like to reduce that number to reduce the HTTP requests. I tried following the post here - [URL] - but am getting errors when trying to do what it instructs, such as:
Microsoft JScript runtime error: 'Sys' is undefined Microsoft JScript runtime error: ASP.NET Ajax client-side framework failed to load. Below is the code I am using for the ScriptManager. These errors go away if I do not use CompositeScript. Has anyone else attempted to combine these files? Am I doing something wrong in this code?
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.
<asp:Content ID="TitleContent1" ContentPlaceHolderID="PageTitlePlaceHolder" runat="Server"> My Page </asp:Content>
This works by placing the content page specific title on the page ("My Page" in this example). Now I want to add a global prefix to the title in my master page for the site name. So I want:
I am using Master page and Content page combination.But how can i access <body> tag and it's event (onload, onunload) of Master page in .aspx page that is not a content page.
I have a master page homeMaster.aspx and many content pages. However the situation is I have few .html pages. Now when a user clicks on a link the html page should get loaded.inside the master page. The problem is these are .html and not content page with .aspx.
I've encountered a problem when I put a treeview in a page which is using master page. The treeview style doesn't apply.For example, I set the nodes with different colors in different levels. But the treeview nodes are still displayed in the default color(bule).
The treeview code is :
[Code]....
If I use these code in a page which doesn't use a master page. The nodes are shown in colors.
Per different user mode, some pages should not be accessible by users unless they have a valid session key.In your opinions -- would it be better to have a list of acceptable pages in the master page, and check if the current page is valid for the current user? Or handle this on every child page?I'm thinking master page, just want to hear what your input would be.
I wrote a page Page method in my aspx page. in web service method I need to call FindControl method return textbox and get text box value. But my findControl will take MasterPage object to iterate.
code.<script type = "text/javascript"> function ShowCurrentDateTime() { $.ajax({ [code]....
But I am getting compiler error when use Page.Master: Reference to non-shared member requires an object reference
How to pass Master Page object or Page to Page method?. So I can use in Sared method.Is there any way I can access Textbox value directly in Page method? I need access couple of controls in Page Method.
How can I use double buffering in asp.net C#?I want smthng like that : I dont want full page refresh when I click a button in a web page.. I think it can be solved with double buffering. When a button clicked for redirect a content page (button-in master page), current page will not go until the redirected page completely load in the background..
I am wondering if there is anyway to grab the html that is generated from an ASP page.I am trying to pull a table from the page,and I foolishly used a static html page so I would not have to be constantly querying the server where this page resides while I tested out my code.The javascript code I wrote to grab to unlabeled table from the page works.Then when I put it into practice with the real page and found that the ASP page does not generate a viewable page with a jquery .get request on the URL.
Is there any way to query the page for the table I need so that the ASP page returns a valid page on request?(I am also limited to using javascript and perl for this,the server where this will reside will not run php and I have no desire to learn ASP.NET to solve this by adding to the issue of proprietary software)
I am a bit confused about these two sequence of events or processes happening in conjunction to each other. Does the page handler executes first or does the somepage.aspx get execute first or do they happen simultaneously?
In my ASP.Net web application, I have a base page that implements functionality that spans all pages of the web application and my web pages derive from this base page. Since there is a single master page for the entire website, I don't want to attach the master page in each of the web pages. So I attached the Master page via the basepage's OnPreInit method as follows:
However, when I switch to Designer view, I get the "Master Page Error"; The page has controls that require a Master Page reference, but noe is specified. Correct the problem in Code View.When I run the application, the webpage shows up correctly.What should be done so that the designer shows up correctly without having to go and set the master page explicitly in each of the web pages?
I want to use Javascript Alert to show errors and warnings to my users so I wrote a method for this purpose which is part of a class. The code is as follows:
