ShowDialog允許在WPFVB.NET下面的MainWindow上觸發事件-有解無憂

我有一個主視窗和一個對話視窗。主視窗上有一個帶有 PreviewMouseLeftButtonUp 事件和一個按鈕的路徑。該按鈕為我的對話視窗打開一個“ShowDialog”。此對話框視窗上有一個標簽，帶有用于關閉對話框的 PreviewMouseLeftButtonDown 事件。對話框直接在路徑上打開。當我單擊標簽關閉對話框時，路徑 PreviewMouseLeftButtonUp 事件也會觸發。我如何防止這種情況？我希望這是有道理的，并感謝您在這方面給我的任何幫助。

這是我的 MainWindow 代碼：

<Window x:Class="MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:local="clr-namespace:DialogTest"
    mc:Ignorable="d"
    Title="MainWindow" Height="695" Width="958" WindowStartupLocation="CenterScreen">
<Grid>
    <Button x:Name="button" Content="Button" HorizontalAlignment="Left" Height="62" Margin="10,0,0,0" VerticalAlignment="Top" Width="138" />

    <Path Data="M0,0L32,0 32,32 0,32z" Stretch="Uniform" Fill="Red" Margin="-167,62,-76,0" RenderTransformOrigin="0.5,0.5"  PreviewMouseLeftButtonUp="Path_PreviewMouseLeftButtonUp">
        <Path.RenderTransform>
            <TransformGroup>
                <TransformGroup.Children>
                    <RotateTransform Angle="0" />
                    <ScaleTransform ScaleX="1" ScaleY="1" />
                </TransformGroup.Children>
            </TransformGroup>
        </Path.RenderTransform>
    </Path>

</Grid>

MainWindow 背后的代碼：

Class MainWindow


Private Sub button_Click(sender As Object, e As RoutedEventArgs) Handles button.Click
    Dim win As New dialog
    win.ShowDialog()
End Sub



Private Sub Path_MouseLeftButtonUp(sender As Object, e As MouseButtonEventArgs)

End Sub

Private Sub Path_PreviewMouseLeftButtonUp(sender As Object, e As MouseButtonEventArgs)
    MsgBox("ClickedPreview")
End Sub

對話框視窗的代碼：

<Window x:Class="dialog"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:local="clr-namespace:DialogTest"
    mc:Ignorable="d"
    Title="dialog" Height="146" Width="132" WindowStartupLocation="CenterScreen">
<Grid>
    <Label x:Name="label" Content="Label" HorizontalAlignment="Center" Height="88" Margin="0,10,0,0" VerticalAlignment="Top" Width="112"/>

</Grid>

以及對話框視窗背后的代碼：

Public Class dialog
Private Sub label_PreviewMouseLeftButtonDown(sender As Object, e As MouseButtonEventArgs) Handles label.PreviewMouseLeftButtonDown
    Me.Close()
End Sub

uj5u.com熱心網友回復：

只是讓任何人知道我通過將標簽更改為按鈕來解決此問題。按鈕單擊事件不會觸發下方的單擊事件。
