如何获取控件模板中的图像源
我添加了一个像这样的按钮:
<Button x:Name="myButton"
Style="{StaticResource myButtonStyle}"
Height="36"
VerticalAlignment="Top"
Click="myButton_Click">
<Grid>
<Image Height="*" Width="31" Source="{Binding Path=Image}" />
<TextBlock Text="{Binding Path=DisplayName}" HorizontalAlignment="Center" />
</Grid>
</Button>
其中“图像”是字符串中所需图像的来源。样式如下:
<Style x:Key="myButtonStyle"
TargetType="Button">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border x:Name="myButtonRootBorder">
<StackPanel Orientation="Horizontal">
<Image Source="{??}" Width="{??}" Height="{??}" />
<!--ContentPresenter-->
<ContentPresenter Grid.Column="1"
HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
Content="{TemplateBinding Content}" />
</StackPanel
</Border>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
现在如何在控件模板中设置图像的高度、宽度和来源。
请帮忙。提前致谢。
I've added one button like this:
<Button x:Name="myButton"
Style="{StaticResource myButtonStyle}"
Height="36"
VerticalAlignment="Top"
Click="myButton_Click">
<Grid>
<Image Height="*" Width="31" Source="{Binding Path=Image}" />
<TextBlock Text="{Binding Path=DisplayName}" HorizontalAlignment="Center" />
</Grid>
</Button>
Where 'Image' is the source of the required image in string. And the style is as follows:
<Style x:Key="myButtonStyle"
TargetType="Button">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border x:Name="myButtonRootBorder">
<StackPanel Orientation="Horizontal">
<Image Source="{??}" Width="{??}" Height="{??}" />
<!--ContentPresenter-->
<ContentPresenter Grid.Column="1"
HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
Content="{TemplateBinding Content}" />
</StackPanel
</Border>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Now how to set the height, width and source of the image in the control template.
Please help. Thanks in advance.

对于宽度和高度,您可以使用
{TemplateBinding Width}
和{TemplateBinding Height}
。如果您希望图像可自定义,您应该继承按钮类并添加 imagesource 属性:然后您可以对图像使用
{TemplateBinding ImageSource}
。For width and height you can use
{TemplateBinding Width}
and{TemplateBinding Height}
. If you want the image to be customizable you should inherit the button class and add an imagesource property:Then you can use
{TemplateBinding ImageSource}
for the image.
