C1.Silverlight Namespace > CommandManager Class : RequerySuggested Event

Occurs when the CommandManager detects conditions that might change the ability of a command to execute.

Syntax

Visual Basic
C#

'Declaration
 
Public Event RequerySuggested As System.EventHandler

'Usage
 
Dim instance As CommandManager
Dim handler As System.EventHandler
 
AddHandler instance.RequerySuggested, handler

public event System.EventHandler RequerySuggested

Remarks

Contrary to WPF System.Windows.Input.CommandManger implementation, CommandManager doesn't track layout changes. So, this event might not be called at some conditions. If you came across this issue, use InvalidateRequerySuggested method for explicit check.

Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
