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.
