I am creating a new project from the ground up. I have my web application in this web application I have references set up to multiple class libraries.
In one of those libraries I have some general Javascript files (like jQuery) that I need to load in my web application's mastersheet. I cannot seem to get at the Javascript.
How can I access that Javascript, located in a different class library, from my web application project?
Attached is a screen shot for better clarity.
Update: Is there any way do achieve this without using ScriptManager?

If you are looking to get out of using the ScriptManager but still retain the ability to store libraries in your DLL, try the following:
I've include a short example of how to achieve this.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.UI;
namespace Mri.Controls
{
public class ScriptLoader : Control
{
protected List<string> ScriptUrls;
public ScriptLoader()
{
ScriptUrls = new List<string>();
}
// Have to add libraries here because cannot access the Page object from the Constructor
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
AddScriptKey("Mri.Controls.Resources.Scripts.Libraries.jQuery.js");
}
public void AddScriptKey(string key)
{
// Using the assembly location, find the WebResourceUrl
var webResourceUrl = Page.ClientScript.GetWebResourceUrl(typeof(ScriptLoader), key);
AddScriptUrl(webResourceUrl);
}
public void AddScriptUrl(string url)
{
// Check to see if script already exists
if (!ScriptUrls.Any(s => s.Equals(url)))
ScriptUrls.Add(url);
}
protected override void Render(HtmlTextWriter writer)
{
// Render the script tags
foreach (var scriptUrl in ScriptUrls)
{
writer.Write(string.Format("\n<script type=\"text/javascript\" src=\"{0}\"></script>", scriptUrl));
}
}
}
}
<pages>
<controls>
<add tagPrefix="mri" namespace="Mri.Controls" assembly="Mri.Controls"/>
</controls>
</pages>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Page Title</title>
<mri:ScriptLoader id="scriptLoader" runat="server" />
</head>
<body>
<form id="form1" runat="server">
<asp:ContentPlaceHolder ID="cphBody" runat="server" />
</form>
</body>
</html>
I hope this was along the lines of what you were looking for.
