Class ClientScriptProxy

This is a proxy object for the Page.ClientScript and MS Ajax ScriptManager object that can operate when MS Ajax when present otherwise falling back to Page.ClientScript. Because MS Ajax may not be available accessing the methods directly is not possible and we are required to indirectly reference client script methods through this class.

This class should be invoked at the Control's start up and be used to replace all calls Page.ClientScript. Scriptmanager calls are made through Reflection indirectly so there's no dependency on the script manager.

This class also provides a few additional page injection helpers like the abillity to load scripts in the page header (rather than in the body) and to use script compression using wwScriptCompressionModule without using MS Ajax.

	ClearContextItemsOnTransfer	Clears all the request specific context items which are script references and the script placement index. public void ClearContextItemsOnTransfer();
	GetClientScriptResourceUrl	Works like GetWebResourceUrl but can be used with javascript resources to allow using of resource compression (if the Script Compression Module is loaded). public string GetClientScriptResourceUrl(Control control, Type type, string resourceName); public string GetClientScriptResourceUrl(Type type, string resourceName);
	GetWebResourceUrl	Returns a WebResource URL for non script resources public string GetWebResourceUrl(Control control, Type type, string resourceName); public string GetWebResourceUrl(Type type, string resourceName);
	IsMsAjax	Checks to see if MS Ajax is registered with the current Web application. public static bool IsMsAjax();
	IsScriptManagerOnPage	Checks to see if a script manager is on the page public bool IsScriptManagerOnPage(Page page);
	LoadControlScript	High level helper function that is used to load script resources for various AJAX controls Loads a script resource based on the following scriptLocation values: public void LoadControlScript(Control control, string scriptLocation, string resourceName, ScriptRenderModes renderMode); public void LoadControlScript(Control control, string scriptLocation, string resourceName); public void LoadControlScript(Control control, string scriptLocation);
	RegisterClientScriptBlock	Registers a client script block in the page. public void RegisterClientScriptBlock(Control control, Type type, string key, string script, bool addScriptTags); public void RegisterClientScriptBlock(Control control, Type type, string key, string script, bool addScriptTags, ScriptRenderModes renderMode);
	RegisterClientScriptInclude	Registers a script include tag into the page for an external script url. public void RegisterClientScriptInclude(Control control, Type type, string key, string url); public void RegisterClientScriptInclude(Control control, Type type, string url, ScriptRenderModes renderMode);
	RegisterClientScriptResource	Returns a WebResource or ScriptResource URL for script resources that are to be embedded as script includes. public void RegisterClientScriptResource(Control control, Type type, string resourceName, ScriptRenderModes renderMode);
	RegisterCssLink	Registers a CSS stylesheet in the page header and if that's not accessible inside of the form tag. public void RegisterCssLink(Control control, Type type, string key, string url);
	RegisterCssResource	Registers a CSS Web Resource in the page public void RegisterCssResource(Control control, Type type, string resourceName);
	RegisterHiddenField	Injects a hidden field into the page public void RegisterHiddenField(Control control, string hiddenFieldName, string hiddenFieldInitialValue);
	RegisterStartupScript	Registers a startup code snippet that gets placed at the bottom of the page public void RegisterStartupScript(Control control, Type type, string key, string script, bool addStartupTags);
	Current	Current instance of this class which should always be used to access this object. There are no public constructors to ensure the reference is used as a Singleton to further ensure that all scripts are written to the same clientscript manager.
