Embedded JavaScript Resources

9,735 Recognized Expert Moderator Expert

I am attempting to use embedded resources in an Ajax Enabled ASP.NET Web Application. I'm using Visual Studio 2008 and VB.NET server side code.

The project is called "EmbeddedResour ces" with the namespace "EmbeddedResour ces"

My resources are not included when the content is rendered in the browser.
I have marked my JavaScript resource as Embedded. I am able to retrieve the path to the resource from the WebResource.axd HTTP Handler during run time; however that resource can never be found by the browser during run time.

I have an embedded JavaScript file named "ChangeTextboxB g.js" located in the root directory of my project with the following contents:

Expand|Select|Wrap|Line Numbers

  
function ChangeBackgroundColor(ctrl)

{

    ctrl.style.backgroundColor = "#C00000";

}

I have an ASPX page named "Index.aspx " with the following contents:

Expand|Select|Wrap|Line Numbers

 
<%@ Page Language="vb" AutoEventWireup="false" MasterPageFile="~/Master.Master" CodeBehind="Index.aspx.vb" Inherits="EmbeddedResources.Index" 

    title="Untitled Page" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">

</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">

<asp:TextBox ID="CrazyTextBox" runat="server"></asp:TextBox>

</asp:Content>

The VB.NET Server Side code (code behind) for this page is as follows:

Expand|Select|Wrap|Line Numbers

 
Partial Public Class Index

    Inherits System.Web.UI.Page
 
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
 
    End Sub
 
    Private Sub Index_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender

        Dim pathToResource As String = Page.ClientScript.GetWebResourceUrl(Me.GetType, "EmbeddedResources.ChangeTextboxBg.js")

        Page.ClientScript.RegisterClientScriptInclude("testResource", pathToResource)

        'ScriptManager.RegisterClientScriptInclude(Me, Me.GetType, "testing", ResolveClientUrl(pathToResource))

        CrazyTextBox.Attributes.Add("onkeypress", "ChangeBackgroundColor(this);")

    End Sub

End Class

And I have a Master page named Master.Master which contains the ScriptManager for the site:

Expand|Select|Wrap|Line Numbers

 
<%@ Master Language="VB" AutoEventWireup="false" CodeBehind="Master.master.vb" Inherits="EmbeddedResources.Master" %>
 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
 
<html xmlns="http://www.w3.org/1999/xhtml" >

<head runat="server">

    <title>Untitled Page</title>

    <asp:ContentPlaceHolder ID="head" runat="server">

    </asp:ContentPlaceHolder>

</head>

<body>

    <form id="form1" runat="server">

    <div>

        <asp:ScriptManager ID="ScriptManager1" runat="server" />

        <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
 
        </asp:ContentPlaceHolder>

    </div>

    </form>

</body>

</html>

I have marked the embedded resource (changeTextboxB g.js) as being accessible through the WebResource.axd HTTP Handler by adding the following line to my AssemblyInfo.vb

Expand|Select|Wrap|Line Numbers

 
<Assembly: WebResource("EmbeddedResources.ChangeTextboxBg.js", "text/javascript")> 
 

As you can see I attempted using the ScriptManager to include the resource to the page, but this made no difference.

I've also attempted change the properties on the "ChangeTextboxB g.js" embedded file so that it copies itself to the output directory...but this also made no difference.

I am completely baffled as to why this doesn't work.
If anyone has any idea of what the problem may be I'd be happy to hear your thoughts!

Thanks a lot

Ok!

I finally got my Embedded JavaScript Resource to work in the page.
I added a ScriptManagerPr oxy called "scriptMP" to my Index.aspx page and added my script to that in my PreRender event:

Expand|Select|Wrap|Line Numbers

 
 Private Sub Index_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender

        Dim pathToResource As String = "ChangeTextboxBg.js"

        Dim sr As New ScriptReference

        sr.Path = pathToResource

        sr.Assembly = "EmbeddedResources"

        sr.Name = "EmbeddedResources.ChangeTextboxBg.js"

        scriptMP.Scripts.Add(sr)

        CrazyTextBox.Attributes.Add("onkeypress", "ChangeBackgroundColor(this);")

    End Sub

Note the that I set the ScriptReference Name property to include the Assembly Name that the Embedded JavaScript Resource is a part of (line 6 in the above code). This is important, otherwise it wont find the resource.

Now I get to apply this stuff to my real project :D :D

Just a little bit more information...i f you are not using an embedded resource with you do not set the Assembly and do not set the Name Properties of the ScriptReference that you are adding to the ScriptProxy.

eg:

Expand|Select|Wrap|Line Numbers

 
    Private Sub Index_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender
 
        'Dim pathToResource As String = "ChangeTextboxBg.js"

        Dim pathToResource As String = "NotEmbeddedScript.js"

        Dim sr As New ScriptReference

        sr.Path = pathToResource

        'sr.Assembly = "EmbeddedResources"

        'sr.Name = "EmbeddedResources.ChangeTextboxBg.js"

        scriptMP.Scripts.Add(sr)

        CrazyTextBox.Attributes.Add("onkeypress", "ChangeBackgroundColor(this);")

    End Sub

The code in the JavaScript file (named "NotEmbeddedScr ipt.js") used in this example is as follows:

Expand|Select|Wrap|Line Numbers

 
function ChangeBackgroundColor(ctrl)

{

        ctrl.style.backgroundColor = "#0000C0";

        ctrl.style.color = "#FFFFFF";

}

Cheers!!
