Javascript - Combining Conditions Included Script Files?
Feb 1, 2010
We are working on an ASP.NET CMS project using jQuery as the basis for our client side scripting. The jquery-1.2.6.js file is the only script file that is always included. Other script files are currently included depending on what components the CMS editor is using on a page or page template.A lot of the script combiners produce a static script. If we took that approach we would have to add all possible script files in just in case they were needed. We are not currently using any of the ASP.NET Ajax extensions so have not looked at what that may give us.

For the sake of client-side performance, it's best to minimize the number HTTP requests to load a page. Is it possible to combine the contents of all Javascript files stored in the "Style Library" such that the client only has to make one request instead traditionally, a request for each Javascript file?

I have a Asp.Net Web Application that uses Themes. Inside the theme directory are 9 *.css files.
I've published the Web Application months ago on a IIS 7.5 (and updated regularry). If I browse the site from my computer, my private computer or some virtual machines at a hosting facility, the site will be perfectly rendered.
However, some employees of the company we created the page for are recently having display issues. I was just able to reproduce the issue via remote session and found out, that only 8 of the 9 styles in the selected Theme directory are included into the page. (IE developer toolbar showed the this)
The client is using Internet Explorer in version 8.
The problem does not only seem to affect employees of the same company rather than visitors from outside as well.The name of the stylesheet, that sometimes not included into the page is called style.css.
I've checked if the file was not accessible from the computer I created the remote session with, but that was not the case. The style.css was browsable. For now I'd try to move the style.css out of the App_Themes directory and include it manually via the MasterPage.
Update: I also discovered that some
<asp:Images ImageURl="~/images/mypic.png">
are also not being shown, just the red X for image not found. Maybe that's related? I looked for the Internet Explorer setting multimedia -> show images, it was checked. I'll try to replace the pngs with jpgs for now.

I would like to implement the application where user can include the different CSS files when clicked on different buttons. how this can be achieved. I don't want to use the theme feature.
I am trying to change the CSS but I have noticed the ungly behaviour as follows:
When using mozilla i see the source code for page i see code for latest CSS. But its not getting downloaded/ tried using the tamper data request to download CSS is not getting sent. When I inspect the elements style is still the old file

So the problem is the following :
i do have own user control. which has some javascript file in script tag included like this
<script type="text/javascript" src="../somefile.js" ></script>
or some javascript code directly on the ascx page. everything works if i place this control somewhere in aspx markup. but if i add this control to the page dynamically to some UpdatePanel place holder on postback (this is logic i can not alter), control renders itself and then i get js error message, which says that functions which are placed in somefile.js are not defined/are null. Why is this happening ? Is there anyway to force js including in this case.
the code amount is huge and i was not able to provide a simplified example with the same error,.
The script is included but somehow the functions are not defined. I'm novice to js, so is it possible that just the script is included but not executed, so the functions are not declared ???
The interesting is that if on some page my custom control is declared in aspx.

I'm building several user controls (ASCX) for my website and several of them are very similar in what they do. (As a side note, I must create unique UC's even if they're similar because I'm creating widgets for the new Telligent Community themeing system). For example, two of them are different but use the same front-end code to create a 2 or 3 tab panel where you can click a tab and it changes the data below. I have a single JS file to handle these tabs and the animations. I'm currently dynamically adding my JS file reference to the <head> from the user controls' code via:
Literal jsFile = new Literal();
jsFile.Text = string.Format("<script src="{0}"></script>", "/community/themes/test/js/tabbedCallout.js");
Page.Header.Controls.Add(jsFile);
If I have both of these controls on a page though, both will add this JS file reference. How can I do a check to see if it is already added from another control?

I use the code bellow to dynamically include a CSS file:
HtmlHead head = (HtmlHead)Page.Header;
HtmlLink link = new HtmlLink();
link.Attributes.Add("href", Page.ResolveClientUrl("~/App_Themes/Default/StyleSheet.css"));
link.Attributes.Add("type", "text/css");
link.Attributes.Add("rel", "stylesheet");
head.Controls.Add(link);
The problem is: I want to do it only once, and only if it isn't alrealy included in the page.
How do I verify if it is already included?
Edit:
Answers telling me to include in page load using !IsPostBack won't solve my problem, as this code will be inside a Web User Control and my page may have a lot of the same user control.
For example, I use the code below to do it with javascript:
if (!Page.ClientScript.IsClientScriptIncludeRegistered("jsScript"))
{
Page.ClientScript.RegisterClientScriptInclude("jsScript", ResolveUrl("~/Utilities/myScript.js"));
}

I have an IIS web site. This web site contains other web sites so the structure is like this.

The problem is that it now tries to find the file at http:serverMainWebSiteScripts....
How can I work around that? Should I put all my scripts and CSS files into the root directory, is that a preferred solution?

I've been working on this for a while and was wondering if anyone has run into the issue of error 404 on IIS. More specifically, when I type in http://localhost/test/test.aspx, the page runs, but the referenced files (JS and CSS) are not being used.

I am developing a website in ASP.NET and I am using various javascript frameworks/libraries. The different files belonging to these frameworks/libraries rarely changes thus there is no reason to refresh those files once they have been sent to the client browser (atleast not everytime a page is served).I see that the HttpContext object can be used somehow, that I can set the content expiration on the files/folders on the IIS, or maybe setup somekind of caching in the web.config file. 1. What is best practice/what approach should I take

I have a site under construction which has a control panel for login/logout and it is in an include file on every page.
We currently have a "login page" which functions just fine but I want to take that and incorporate it into the control panel so the user could log in from any page.
Problem is that the .NET programmer wrote all of the login logic using code behind only on one single page.
Is there some way for me to work around this or to incorporate this vb code into every page so that the cpanel can function as it should?

I have an editor in which user enters the data from any other website. The issue is while pasting such data, the css of that website is also included which disturbs my page. When the entire data is displayed I don't have any problem whereas when I trim the data such as first 100 characters alone are displayed then the content overlaps my style and gets exceeded from the alignment.

I recently ran yslow on a page i have (master paged etc) and it returned that there were far too many javascript files included (most of which I haven't added).
I guess my question is that given i have v1.0.20229.0 of the toolkit.dll (over .net 2)
I'm wondering if subsequent releases have fixes for this sort of thing?
