我在我的WPF應用程序中有幾個彈出窗口,它工作正常。vb.net wpf popup沒有焦點

但是,這最後一個不接受文本框中的焦點或輸入。我不明白爲什麼。

    <Label x:Name="lblSearch" Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="1" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="0,5" Height="30" Width="Auto">Search</Label> 
        <TextBox Name="txtSearch" Grid.Row="0" Grid.Column="1" Grid.ColumnSpan="1" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="0,5" Height="30" Width="200" IsReadOnly="False" IsEnabled="True"></TextBox> 
        <Button Name="btnSearch" Grid.Row="0" Grid.Column="2" Style="{StaticResource ButtonSmall}" Template="{DynamicResource BlackButton}" Margin="5">Search</Button> 

        <Label x:Name="lblReplace" Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="1" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="0,5" Height="30" Width="Auto">Replace</Label> 
        <TextBox Name="txtReplace" Grid.Row="1" Grid.Column="1" Grid.ColumnSpan="1" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="0,5" Height="30" Width="200" IsReadOnly="False" IsEnabled="True"></TextBox> 
        <Button Name="btnReplace" Grid.Row="1" Grid.Column="2" Style="{StaticResource ButtonSmall}" Template="{DynamicResource BlackButton}" Margin="5">Replace</Button> 

        <Button Name="btnStopSearch" Grid.Row="2" Grid.Column="3" Style="{StaticResource ButtonSmall}" Template="{DynamicResource BlackButton}" Margin="5">Done</Button> 

        <DockPanel Grid.Row="2" Grid.Column="0" Grid.ColumnSpan="2"> 
        </DockPanel> 
       </local:GridEx> 
      </DockPanel> 
     </Border> 
    </Border> 
</Popup> 

我想這個代碼強制專注於它,但無濟於事:

Private searchWhere As String = Nothing 
Private Sub txtTypeEditor_keyDown(sender As Object, e As Forms.KeyEventArgs) Handles txtTypeEditor.KeyDown 
    If e.KeyCode = Forms.Keys.F AndAlso e.Control AndAlso Not e.Alt AndAlso Not e.Shift Then 
     PopupSearch.IsOpen = True 
     txtSearch.Focus() 
     Keyboard.Focus(txtSearch) 
     searchWhere = "TypeEditor" 
     e.Handled = True 
    End If 
End Sub 

Private Sub Popup1_Opened(sender As Object, e As EventArgs) Handles PopupSearch.Opened 
    txtSearch.Focus() 
    Keyboard.Focus(txtSearch) 
End Sub 

看樣子txtTypeEditor保持在聚焦。任何想法如何模糊它?

我現在有一個解決方法:如果我通過聚焦另一個文本框來模糊文本框,那麼彈出框接受焦點。

但是,如果用戶單擊到txtTypeEditor文本框中,然後單擊彈出框中的輸入字段,則鼠標焦點切換到彈出窗口,但鍵盤焦點仍保留在文本框中。

這只是一個猜測: 這可能與txtTypeEditor_keyDown事件在txtTypeEditor中保持某種程度有關嗎? 你可以給它keyPress而不是一試(如果它不影響你的代碼的任何其他部分)

我不知道如何檢查與按鍵 – Adder

CTRL-F鍵,你可以通過_keydown捕捉按CTRL並在處理程序中設置一個布爾值ctrl = true,然後在_keyPress中檢查「F」beeing按下並且ctrl = true – DonGru
