Imagebutton更改源属性 [英] Imagebutton change source property

问题描述

我正在开发Windows Phone应用。

I'm developing a Windows Phone app.

我有一个带有图像的自定义按钮。这是它的XAML代码：

I have a custom button with an image inside. This is its XAML code:

<ControlTemplate x:Key="ImageButton" TargetType="Button">
    <Grid>
        <Image Margin="45,8,35,8" Source="Images/Delete.png"/>
    </Grid>
</ControlTemplate>

如何以编程方式更改Image Source属性？

How can I change Image Source property programmatically?

推荐答案

要更改图像的来源，您需要制作资产的新位图并将其设置为源

To change the source of an image you need to make a new bitmap of your asset and set it as a souce

BitmapImage myBitmapImage = new BitmapImage(new Uri("/Images/foo.png", UriKind.Relative));

imageButton.Source = myBitmapImage;

但是我想你想有一个可以改变背景的按钮如果单击。您需要重新定义按钮的视觉状态。这是一个示例：

but I guess you would like to have a button that change its background if is clicked. You need to redefine Visual States of the button. Here is an example:

Windows Phone 7（WP7）更改单击时按钮的背景颜色
