Is it possible to add javascript reference dynamically from code behind aspx.cs?Like this:
private void AddScriptReference(string path)
{
//Add reference to <head></head>
}

I am working on converting a project from C# to VB and am facing this weird issue. 1 page cannot compile and I get the reference error, but the weird thing is that the compiler shows the error as coming from ASP.NET generated code. Visual Studio shows me that error is coming from my ASPX page. I cannot seem to figure out why or where this error is occuring. Also if I take the inherits attribute out I don't get the compilation error. The code in aspx page is below:

I've inherited some code (not mine- I swear!) which uses a session variable in the header of the HTML to determine which javascript file to link to.
<SCRIPT language="javascript" src="../JavaScript/<%=Session("jsFileName")%>.js"></SCRIPT>
It does work, except that it won't let me change to design view. It gives the message "Could not open in design view. Quote Values differently inside a '<%... "value" ...%>' block.
In .Net I can use the "~/image/image.png" as a reference to a graphic in the image file in the image folder from whatever file or folder I am working with. How do i use this type of reference in a javascript where I need to reference a source file?
View 4 RepliesI have a <div> element in a web page. I've assigned it an "ID" and made it a server-side control by using "runat=server". How do I define that <div> in the code-behind. I'm been looking at the "System.Web.UI.HtmlControls" namespace and not sure what to use. The reason I need to do this is because within this <div> is a "Submit" button which will cause a postback. When I click the submit button the first thing it does is it executes a procedure to perform edit checks on the various textbox controls. If a control is empty, a message pops up. When the user clicks "Ok" for the message, the <div> disappears because when the form loads, the <div> style.display property is set to "none" by default. Basically, all I want is for the <div> not to disappear when the edit checks are performed and a messagebox pops up.
View 7 RepliesI have a hquery plugin that consists of jquery itself, 2 .js files and some script to configure the plug-in which resides on the page. I noticed that in .net you can create a .js file.What I would like to do is put the configuration inside a .js file created in .net, but how do I then reference this in the header of the page?am I over complicating the issue or just missing something?
View 5 RepliesI have some pages that reference javascript files.
The application exists locally in a Virtual Directory, i.e. http://localhost/MyVirtualDirectory/MyPage.aspx
so locally I reference the files as follows:
<script src="/MyVirtualDirectory/Scripts/MyScript.js" type="text/javascript"></script>
The production setup is different though. The application exists as its own web site in production, so I don't need to include the reference to the virtual directory. The problem with this is that I need to modify every file that contains a javascript reference so it looks like the following:
<script src="../Scripts/MyScript.js" type="text/javascript"></script>
I've tried referencing the files this way in my local setup but it doesn't work.
I'm trying to call a Page Method using a jQuery 'attached' event function, in which I like to use the closure to keep the event target local, as below, but page method calls declare several 'error' functions, and I would like to use one function for all of them. If, in the below code, I was handling an error and not success, how could I use my single, anonymous handler for all 3 error functions?
$(":button").click(function () {
var button = this;
PageMethods.DoIt(
function (a, b, c) {
alert(button);
});
});
This example passes an anonymous function for the success callback. There is only one of these. If I was passing an error callback, how could I use 'function (e, c, t)' for all 3 error callbacks?
ADDED: What I would like to do here is trigger an AJAX call whenever the user clicks a toggle button (checkbox), but to improve responsiveness, I want to toggle the button state immediately, and only 'untoggle' it if the AJAX call fails.
Now, in my client-side click() event handler, I would like to use anonymous functions inside the scope of click()' so that the functions have access to thethisevent argument, but I don't want to 'declare' three functions for theonTimeout,onError, and 'onAbort arguments of the PageMethods.MyFunction function. if I declare a named function outside of the click handler, it no longer has access to the 'this' parameter of the click() event handler.
When we reference a DLL. It creates that DLL in the BIN folder of our project.My question is although the BIN folders are not included in the web application project thenhow come all the code works? When I right click on the Bin folder I get an option "Include in Project"So how come I am able to use all the methods inside the dll's in the BIN folder even though the BIN folder itself is not included in the Project? Do we ever include the BIN folders?

I'm trying to use a ModalPopupExtender in a user control, so the TargetControl is on the previous (parent) page. In the PageLoad event of the user control, the following code finds the MPE and the button from the previous page, but I don't understand how to actually assign the button to the MPE as the TargetControlID.

I am writing an application that does it's own logging in a SQL table. On each page, I statically assign this variable: Dim page = "page_01.aspx" I've noticed that page is ALWAYS equal to the name of the Partial Class of the code-behind + the suffix ".aspx" Is there any way to programatically set the string to equal the name of the Partial Class, so I don't have to statically code it on each page? Basically, I want to assign the name of the current class to a string, and append ".aspx" to it. Can I do this, or does that get lost in the compilation?
View 1 RepliesThing is, when my service is providing result of type string my client .aspx page is working fine and it gives reference in my code. But now I changed my service to provide custom data type and I can't see service reference in my code, intellisense doesn't offer it at all. What am I missing here? WCFTestClient.exe is giving good results but I can't create my own in VS 2008
View 1 RepliesI am trying to add a web reference to an ASP.NET 2.0 application in Visual Studio 2008.However, the generated proxy classes do not include BeginXXXX and EndXXXX methods.Hcan I get these to be generated? Do I need to manually use wsdl.exe?(Incidentally in ASP.NET 3.5 apps, there is an option in the Add Service Reference box which lets me specify that Async methods should be generated. However, I am limited to ASP.NET 2.0 implementation).

I have an activex OWC11 Chartspace on my form. I wish to be able to access this object in my code behind page instead of scripting the code in the asp page. Has anyone any idea how to get a handle to the activex chartspace object from the code behind. I know how to create an OCW chart and then display it as a jpeg from the code behind page but the activex chart component offers more use with the chart opbect on the page rather than a jpeg?
