ScriptReferenceEventArgs Class

Provides data for the ResolveScriptReference event.


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

public class ScriptReferenceEventArgs : EventArgs

The ScriptReferenceEventArgs type exposes the following members.

Public methodScriptReferenceEventArgsInitializes a new instance of the ScriptReferenceEventArgs class.

Public propertyScriptGets the ScriptReference object that contains the script library.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

When a script reference is rendered, the ScriptReferenceEventArgs object contains the ScriptReference object that is defined in the ScriptManager instance. You can create an event handler for the ResolveScriptReference event to check the ScriptReference object and modify it as needed.

The following example shows an ASP.NET Web page that references a script file that is named CustomScript.js. When the Web application is hosted on the domain, the Path() property is set to a value specific for that domain. An event handler for the ResolveScriptReference event checks the host URL and changes the value for the Path() property if it is necessary.
