禁用Infragistics工具欄按鈕（ButtonTool）

我需要啓用/禁用ButtonTool。禁用Infragistics工具欄按鈕（ButtonTool）

在使用Infragistics之前，我使用了一個ordinaly WinForms ToolbarButton，它有一個屬性「Enabled」。

我用這樣的數據綁定：我怎會現在使用的Infragistics ButtonTool

UndoButtonTool.DataBindings.Clear() 
UndoButtonTool.DataBindings.Add("Enabled", memory, "CanUndo")

？

做

UndoButtonTool.DataBindings.Clear() 
UndoButtonTool.DataBindings.Add("SharedProps.Enabled", memory, "CanUndo")

將無法正常工作......

我已經實現了一個自定義BindableButtonTool：

Public Class ToolStripBindableButton 
    Inherits Infragistics.Win.UltraWinToolbars.ButtonTool 
    Implements IBindableComponent 

    Private _DataBindings As ControlBindingsCollection 
    Private _BindingContext As BindingContext 
    Private _Site As System.ComponentModel.ISite 

    Public Event DisposedAsStrip As EventHandler Implements IBindableComponent.Disposed 

    Sub New(ByVal name As String) 
    MyBase.New(name) 
    End Sub 

    Public ReadOnly Property DataBindings() As ControlBindingsCollection Implements System.Windows.Forms.IBindableComponent.DataBindings 
    Get 
     If _DataBindings Is Nothing Then 
     _DataBindings = New ControlBindingsCollection(Me) 
     End If 
     Return _DataBindings 
    End Get 
    End Property 

    Public Property BindingContext() As BindingContext Implements System.Windows.Forms.IBindableComponent.BindingContext 
    Get 
     If _BindingContext Is Nothing Then 
     _BindingContext = New BindingContext() 
     End If 
     Return _BindingContext 
    End Get 
    Set(ByVal value As BindingContext) 
     _BindingContext = value 
    End Set 
    End Property 

    Public Overloads Sub Dispose() 
    If _DataBindings IsNot Nothing Then 
     _DataBindings.Clear() 
     _DataBindings = Nothing 
    End If 
    _BindingContext = Nothing 

    MyBase.Dispose() 

    RaiseEvent DisposedAsStrip(Me, EventArgs.Empty) 
    End Sub 

    Property Site As System.ComponentModel.ISite Implements System.ComponentModel.IComponent.Site 
    Get 
     Return _Site 
    End Get 
    Set(ByVal value As System.ComponentModel.ISite) 
     _Site = value 
    End Set 
    End Property 

End Class

T UndoButtonTool.DataBindings.Add（「啓用」，memory.SharedProps，「CanUndo」），它應該工作。我積極使用Infragistics併成功綁定了Enabled屬性。 – 2011-01-22 21:35:29

要啓用/禁用的Infragistics ButtonTool您可以使用下面的代碼

myButtonTool.SharedProps.Enabled = True/False
