public:
 System::String ^ GetCallbackEventReference(System::Web::UI::Control ^ control, System::String ^ argument, System::String ^ clientCallback, System::String ^ context);

public string GetCallbackEventReference (System.Web.UI.Control control, string argument, string clientCallback, string context);

member this.GetCallbackEventReference : System.Web.UI.Control * string * string * string -> string

Public Function GetCallbackEventReference (control As Control, argument As String, clientCallback As String, context As String) As String

Parameters

control: Control

The server Control that handles the client callback. The control must implement the ICallbackEventHandler interface and provide a RaiseCallbackEvent(String) method.

argument: String

An argument passed from the client script to the server

RaiseCallbackEvent(String) method.

clientCallback: String

The name of the client event handler that receives the result of the successful server event.

context: String

The client script that is evaluated on the client prior to initiating the callback. The result of the script is passed back to the client event handler.

Returns

String

The name of a client function that invokes the client callback.

Exceptions

ArgumentNullException

The Control specified is null.

InvalidOperationException

The Control specified does not implement the ICallbackEventHandler interface.

Examples

The following code example demonstrates how to use two overloads of the GetCallbackEventReference method in a client callback scenario that increments integers.

Two callback mechanisms are shown; the difference between them is the use of the context parameter. A ReceiveServerData1 client callback function is provided using the context parameter. In contrast, the ReceiveServerData2 client callback function is defined in a <script> block on the page. A RaiseCallbackEvent method is the server handler that increments the value that is passed to it and the GetCallbackResult method returns the incremented value as a string. If the RaiseCallbackEvent method returns an error, then the ProcessCallBackError client function is called.

Remarks

The GetCallbackEventReference(Control, String, String, String) method performs an out-of-band callback to the server that is a modified version of a page's normal life cycle. For more information, see Implementing Client Callbacks Without Postbacks.

Note

When the browser is Microsoft Internet Explorer (version 5.0 or later), the script callback mechanism is implemented through the Microsoft.XmlHttp COM object and requires the browser to be set to run ActiveX controls. For other browsers, an XMLHttpRequest using the browser's local Document Object Model (DOM) is used. To check whether a browser supports client callbacks, use the SupportsCallback property. To check whether a browser supports XML over HTTP, use the SupportsXmlHttp property. Both properties are accessible through the Browser property of the intrinsic ASP.NET Request object.

The GetCallbackEventReference overload of the GetCallbackEventReference method performs a callback synchronously using XML over HTTP. When sending data synchronously in a callback scenario, synchronous callbacks return immediately and do not block the browser. No two synchronous callbacks callback can execute at the same time in the browser. If a second synchronous callback is fired while one is currently pending, the second synchronous callback cancels the first and only the second callback will return.

To send data asynchronously, use one of the overloads that takes the useAsync parameter, which is a Boolean value controlling this behavior. In the asynchronous scenario you can have multiple pending callbacks; however, the order in which they return is not guaranteed to match the order in which they were initiated.

Additionally, this overload of the GetCallbackEventReference method specifies no client function to handle the case of an error condition generated by the RaiseCallbackEvent method. To specify a client error callback handler, use one of the overloads that takes the clientErrorCallback parameter.

The GetCallbackEventReference(Control, String, String, String) method takes an optional string argument parameter and returns a string. To pass in or to receive multiple values, concatenate values in the input or return string, respectively.

Note

Avoid using the view state in the implementation of page or control properties that need be updated during script callback operations. If the properties are to survive page requests, you can use session state.

Applies to

GetCallbackEventReference(Control, String, String, String, Boolean)

Obtains a reference to a client function that, when invoked, initiates a client call back to server events. The client function for this overloaded method includes a specified control, argument, client script, context, and Boolean value.

public:
 System::String ^ GetCallbackEventReference(System::Web::UI::Control ^ control, System::String ^ argument, System::String ^ clientCallback, System::String ^ context, bool useAsync);

public string GetCallbackEventReference (System.Web.UI.Control control, string argument, string clientCallback, string context, bool useAsync);

member this.GetCallbackEventReference : System.Web.UI.Control * string * string * string * bool -> string

Public Function GetCallbackEventReference (control As Control, argument As String, clientCallback As String, context As String, useAsync As Boolean) As String

Parameters

control: Control

The server Control that handles the client callback. The control must implement the ICallbackEventHandler interface and provide a RaiseCallbackEvent(String) method.

argument: String

An argument passed from the client script to the server

RaiseCallbackEvent(String) method.

clientCallback: String

The name of the client event handler that receives the result of the successful server event.

context: String

The client script that is evaluated on the client prior to initiating the callback. The result of the script is passed back to the client event handler.

useAsync: Boolean

true to perform the callback asynchronously; false to perform the callback synchronously.

Returns

String

The name of a client function that invokes the client callback.

Exceptions

ArgumentNullException

The Control specified is null.

InvalidOperationException

The Control specified does not implement the ICallbackEventHandler interface.

Remarks

This overload of the GetCallbackEventReference method requires a useAsync parameter, which allows you to perform the client callback asynchronously by setting the value to true. The overload versions of this method that do not require the useAsync parameter set the value to false by default.

For more information on this method, see the remarks for the overload GetCallbackEventReference method.

Applies to

GetCallbackEventReference(String, String, String, String, String, Boolean)

Obtains a reference to a client function that, when invoked, initiates a client call back to server events. The client function for this overloaded method includes a specified target, argument, client script, context, error handler, and Boolean value.

public:
 System::String ^ GetCallbackEventReference(System::String ^ target, System::String ^ argument, System::String ^ clientCallback, System::String ^ context, System::String ^ clientErrorCallback, bool useAsync);

public string GetCallbackEventReference (string target, string argument, string clientCallback, string context, string clientErrorCallback, bool useAsync);

member this.GetCallbackEventReference : string * string * string * string * string * bool -> string

Public Function GetCallbackEventReference (target As String, argument As String, clientCallback As String, context As String, clientErrorCallback As String, useAsync As Boolean) As String

Parameters

target: String

The name of a server Control that handles the client callback. The control must implement the ICallbackEventHandler interface and provide a RaiseCallbackEvent(String) method.

argument: String

An argument passed from the client script to the server

RaiseCallbackEvent(String) method.

clientCallback: String

The name of the client event handler that receives the result of the successful server event.

context: String

The client script that is evaluated on the client prior to initiating the callback. The result of the script is passed back to the client event handler.

clientErrorCallback: String

The name of the client event handler that receives the result when an error occurs in the server event handler.

useAsync: Boolean

true to perform the callback asynchronously; false to perform the callback synchronously.

Returns

String

The name of a client function that invokes the client callback.

Examples

The following code example demonstrates how to use two overloads of the GetCallbackEventReference method in a client callback scenario that increments integers.

Remarks

This overload of the GetCallbackEventReference method takes a target string parameter instead of a Control parameter. Use this overload when you want the callback to go back to something other than a string containing the UniqueID of the control.

Additionally, this overload of the GetCallbackEventReference method requires a useAsync and a clientErrorCallback parameter. The useAsync parameter allows you to perform the client callback asynchronously by setting the value to true. The overload versions of this method that do not require the useAsync parameter set the value to false by default. The clientErrorCallback parameter allows you to define the name of the client function that is called if the server handler, the RaiseCallbackEvent method, returns an error. The overload versions of this method that do not require the clientErrorCallback parameter set the value to null.

For more information on this method, see the remarks for the overload GetCallbackEventReference method.

Public Function GetCallbackEventReference (control As Control, argument As String, clientCallback As String, context As String, clientErrorCallback As String, useAsync As Boolean) As String

Parameters

control: Control

The server Control that handles the client callback. The control must implement the ICallbackEventHandler interface and provide a RaiseCallbackEvent(String) method.

argument: String

An argument passed from the client script to the server RaiseCallbackEvent(String) method.

clientCallback: String

The name of the client event handler that receives the result of the successful server event.

context: String

The client script that is evaluated on the client prior to initiating the callback. The result of the script is passed back to the client event handler.

clientErrorCallback: String

The name of the client event handler that receives the result when an error occurs in the server event handler.

useAsync: Boolean

true to perform the callback asynchronously; false to perform the callback synchronously.

Returns

String

The name of a client function that invokes the client callback.

Exceptions

ArgumentNullException

The Control specified is null.

InvalidOperationException

The Control specified does not implement the ICallbackEventHandler interface.
