ScriptManager.RegisterPostBackControl(Control) Method

  • Reference

Definition

Namespace:
System.Web.UI
Assembly:
System.Web.Extensions.dll

Registers a control as a trigger for a postback. This method is used to configure postback controls inside an UpdatePanel control that would otherwise perform asynchronous postbacks.

public:
 virtual void RegisterPostBackControl(System::Web::UI::Control ^ control);
public void RegisterPostBackControl (System.Web.UI.Control control);
abstract member RegisterPostBackControl : System.Web.UI.Control -> unit
override this.RegisterPostBackControl : System.Web.UI.Control -> unit
Public Sub RegisterPostBackControl (control As Control)

Parameters

control
Control

The control to register for postback.

Remarks

Use the RegisterPostBackControl method to register postback controls inside an UpdatePanel control as triggers. Controls that are registered by using this method update a whole page instead of updating only the UpdatePanel control's content. Registering a postback control with this method outside an UpdatePanel control has no affect because by default these controls do not perform asynchronous postbacks.

You can add the trigger declaratively by using the Triggers element of the UpdatePanel control. In Visual Studio, use the designer's UpdatePanelTrigger Collection Editor dialog box.
