Public static (Shared in Visual Basic) members of this type are safe for multithreaded operations. Instance members are not guaranteed to be thread-safe.

Remarks

Callback or CallbackPanel control uses Triggers property to specify a list of CallbackTrigger controls each of which contains information of the control that can trigger the call back.

Any kind of control that can send postback request to server can trigger the callback.

To specify a control's postback request to be handled by Callback or CallbackPanel, create a CallbackTrigger control, set the CallbackTrigger's ControlID property to the client ID of the triggering control, and add the CallbackTrigger into Callback or CallbackPanel's Triggers property.

For example, if the CallbackTrigger's ControlID is an ASP.NET button's client ID, then the button's OnClick event will be raised via Callback without refreshing the whole page.
