Liam Dawson · 技术社区 · 16 年前

我正在尝试设置不透明度属性和变换属性的动画。有人能帮忙吗?提前谢谢。

这里的问题是tab控件没有它所能具有的多功能性。在这种情况下,最好对每个选项卡项使用自定义控件,并创建淡入/淡出的切换故事板。

我的技巧是使用视觉状态和行为,以及自定义模板单选按钮作为切换。

你可以在我的博客上看到这种技术的一个例子,在我的主页silverlightxap的网站部分 http://www.blackspike.com

使用 SelectionChanging 和 SelectionChanged 选择更改 和 选择已更改

VB语言:

Private Sub TabControl_SelectionChanging(sender As Object, e As DevExpress.Xpf.Core.TabControlSelectionChangingEventArgs) Handles tcMaterials.SelectionChanging, tcSymbols.SelectionChanging, myTabControl1.SelectionChanging
    Try
        If Not e.OldSelectedItem Is Nothing Then
            Dim Duration = New TimeSpan(0, 0, 0, 0, 500)

            Dim FromOpac As New DoubleAnimation(1, 0, Duration)

            Storyboard.SetTarget(FromOpac, CType(CType(e.OldSelectedItem, DXTabItem).Content, Grid))
            Storyboard.SetTargetProperty(FromOpac, New PropertyPath((CType(CType(e.OldSelectedItem, DXTabItem).Content, Grid).OpacityProperty)))
            Dim s As New Storyboard()
            s.AccelerationRatio = 0.2
            s.DecelerationRatio = 0.8
            s.Children.Add(FromOpac)

            s.Begin()
        End If
    Catch ex As Exception
        MsgBox(ex.Message)
    End Try

End Sub

Private Sub TabControl_SelectionChanged(sender As Object, e As DevExpress.Xpf.Core.TabControlSelectionChangedEventArgs) Handles tcMaterials.SelectionChanged, tcSymbols.SelectionChanged, myTabControl1.SelectionChanged
    Try
        If Not e.OldSelectedItem Is Nothing Then
            Dim Duration = New TimeSpan(0, 0, 0, 0, 500)

            Dim ToOpac As New DoubleAnimation(0, 1, Duration)


            Storyboard.SetTarget(ToOpac, CType(CType(e.NewSelectedItem, DXTabItem).Content, Grid))
            Storyboard.SetTargetProperty(ToOpac, New PropertyPath((CType(CType(e.NewSelectedItem, DXTabItem).Content, Grid).OpacityProperty)))
            Dim s As New Storyboard()
            s.AccelerationRatio = 0.2
            s.DecelerationRatio = 0.8
            s.Children.Add(ToOpac)

            s.Begin()
        End If
    Catch ex As Exception
        MsgBox(ex.Message)
    End Try

End Sub
