更改複選標記符號WP7

-1

我想將圖像設置爲複選框標記。 WP7有可能嗎？我搜索了複選框的所有屬性，但沒有找到。感謝更改複選標記符號WP7

不能直接複選框使用圖像，但你可以一個標準Button對象上使用的圖像，並在每次點擊時更改背景圖片：

XAML：

<Button Click="Button_Click" x:Name="btnCheckbox"> 
        <Button.Content> 
         <Image Source="Checkbox_Unselected.png" /> 
        </Button.Content> 
       </Button>

代碼背後：

private bool isCheckboxChecked = false; 
private void Button_Click(object sender, RoutedEventArgs e) 
{ 
    isCheckboxChecked = !isCheckboxChecked; 
    this.CheckboxImage.Source = new System.Windows.Media.Imaging.BitmapImage(new Uri((isCheckboxChecked ? "Checkbox_Selected.png" : "Checkbox_Unselected.png"))); 
}

很顯然，這會綁定isCheckboxChecked的財產在你的模型，而不是私法甚至更好吃了變量。

我明白了。您的解決方案是使用按鈕而不是複選框。但實際上，複選框標記只是字母V，我想將其更改爲小圖片。如果沒有其他方法，我會嘗試你的代碼。謝謝 – geeko

您只需更改ContentTemplate中的圖像即可，完全可行。 –

只需編輯它的模板，它的超級容易。您將名爲CheckMark的對象Path更改爲圖像，並且您是黃金版。
