 bool RequiresControlState(System::Web::UI::Control ^ control);

public bool RequiresControlState (System.Web.UI.Control control);

member this.RequiresControlState : System.Web.UI.Control -> bool

Public Function RequiresControlState (control As Control) As Boolean

Parameters

control: Control

The Control to check for a control state requirement.

Returns

Boolean

true if the specified Control requires control state; otherwise, false.

Remarks

Control state is an object composed of critical view-state data that Web server controls need to function; it is contained in a separate object from normal view state.

Custom controls using control state must call the RegisterRequiresControlState method before saving control state. Use the RequiresControlState method to check for controls that are registered with the page as requiring control state.
