ClientScriptManagerRegisterClientScriptResource Method
 

Registers the client script resource with the Page object using a type and a resource name.

Namespace:   System.Web.UI
Assembly:  System.Web (in System.Web.dll)

Syntax
public void RegisterClientScriptResource(
	Type type,
	string resourceName
)
public:
void RegisterClientScriptResource(
	Type^ type,
	String^ resourceName
)
member RegisterClientScriptResource : 
        type:Type *
        resourceName:string -> unit
Public Sub RegisterClientScriptResource (
	type As Type,
	resourceName As String
)

Parameters

type
Type:

The type of the client script resource to register.

resourceName
Type:

The name of the client script resource to register.

Exceptions
Exception Condition
ArgumentNullException

The client resource type is null.

ArgumentNullException

The client resource name is null.

- or -

The client resource name has a length of zero.

Remarks

The RegisterClientScriptResource method is used when accessing compiled-in resources from assemblies through the WebResource.axd HTTP handler. The RegisterClientScriptResource method registers the script with the Page object and prevents duplicate scripts. This method wraps the contents of the resource URL with a <script> element block.

Examples

The following code example demonstrates the use of the RegisterClientScriptResource method.

<%@ Page Language="C#"%>
<%@ Import Namespace="Samples.AspNet.CS.Controls" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">

  public void Page_Load(Object sender, EventArgs e)
  {
    // Define the resource name and type.
    String rsname = "Samples.AspNet.CS.Controls.script_include.js";
    Type rstype = typeof(ClientScriptResourceLabel);

    // Get a ClientScriptManager reference from the Page class.
    ClientScriptManager cs = Page.ClientScript;

    // Write out the web resource url.
    ResourcePath.InnerHtml = cs.GetWebResourceUrl(rstype, rsname);

    // Register the client resource with the page.
    cs.RegisterClientScriptResource(rstype, rsname);

  }
</script>

The following code example demonstrates how to programmatically apply the WebResourceAttribute metadata attribute to mark the assembly for the resources that will be served.

using System;
using System.Web;
using System.Web.UI;
using System.Security.Permissions;

[assembly: WebResource("Samples.AspNet.CS.Controls.script_include.js", "application/x-javascript")]
namespace Samples.AspNet.CS.Controls
{
	[AspNetHostingPermission(SecurityAction.Demand, Level = AspNetHostingPermissionLevel.Minimal)]
	public class ClientScriptResourceLabel
	{
		// Class code goes here.

	}

}
Imports Microsoft.VisualBasic
Imports System
Imports System.Web
Imports System.Web.UI
Imports System.Security.Permissions

<Assembly: WebResource("Samples.AspNet.VB.Controls.script_include.js", "application/x-javascript")> 
Namespace Samples.AspNet.VB.Controls

    <AspNetHostingPermission(SecurityAction.Demand, Level:=AspNetHostingPermissionLevel.Minimal)> _
    Public Class ClientScriptResourceLabel

        ' Class code goes here.

    End Class

End Namespace

This example requires a JavaScript file named Script_include.js, with the following contents:

function DoClick() {Form1.Message.value='Text from resource script.'}

Compile the Script_include.js file as a resource in the Samples.AspNet.CS.Controls assembly that contains the ClientScriptResourceLabel class.
