我正在开发一个 Windows Phone 应用程序。我是 WP7 应用程序开发的新手。在我的应用程序中,我使用的是用户控件,并且通过代码中显示的以下过程更改了它的背景图像。但是背景图像没有改变。谁能帮我 ?这是我的代码片段:
<Grid>
<Image Source="\assests\backgroungimages\appBackground2.jpg" Stretch="UniformToFill"/>
<StackPanel x:Name="LayoutRoot" Width="480" Height="306" Background="Black">

<toolkit:PhoneTextBox Hint="UserName" Name="txtUsername" Width="auto" HintStyle="{StaticResource HintCustomStyle}"></toolkit:PhoneTextBox>
<toolkit:PhoneTextBox Hint="Password" Name="txtPassword" Width="auto" HintStyle="{StaticResource HintCustomStyle}"></toolkit:PhoneTextBox>
<Grid>
