Windows 运行时:如何在椭圆形按钮中设置图像? [英] Windows Runtime: How to set image in a ellipse shape button?

问题描述

<Button x:Name="btnProfilePicture" HorizontalAlignment="Center" Click="btnProfilePicture_Click">
    <Button.Template>
        <ControlTemplate>
            <Ellipse x:Name="ellipsePicture" Fill="Turquoise" Width="150" Height="150" Stroke="White" StrokeThickness="10">
            </Ellipse>
        </ControlTemplate>
    </Button.Template>
</Button >

我有一个椭圆形按钮，默认为颜色填充.我想在运行时在代码隐藏中将填充更改为图像.

I have a button in ellipse shape, with color fill by default. I want to change the fill to an image in code-behind in runtime.

我该怎么做?

更多信息:我尝试使用ellipsePicture"名称设置椭圆填充，但后面的代码中无法引用此名称，但我不知道原因.

More info: I tried to set the ellipse fill by using the "ellipsePicture" name but this name cannot be referenced in the code behind but I dont know the reason.

推荐答案

试试下面的代码..

<Button x:Name="BtnProfilePicture" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="10">
            <Button.Template>
                <ControlTemplate>
                    <Grid Height="100">
                        <Ellipse x:Name="ellipsePicture" Fill="{TemplateBinding Background}"/>
                    </Grid>
                </ControlTemplate>
            </Button.Template>
        </Button >

在后面的代码中添加以下行..

On your code behind add the following line..

BtnProfilePicture.BackgroundImage = 
           new ImageBrush { ImageSource = LoadBackgroundImage(yourfilename.jpg)};
