Creating an image+text button with a control template? - wpf

Question

I am tired of creating the same image+text button over and over again, and I would like to move the markup to a control template. Here is my problem: I need to provide template bindings to add the image and text to the templated button, and the Button control doesn't seem to have properties that I can bind to.
My template looks like this so far (with '???' for the unknown template bindings):
<ControlTemplate x:Key="ImageButtonTemplate" TargetType="{x:Type Button}">
<StackPanel Height="Auto" Orientation="Horizontal">
<Image Source="{TemplateBinding ???}" Width="24" Height="24" Stretch="Fill"/>
<TextBlock Text="{TemplateBinding ???}" HorizontalAlignment="Left" Foreground="{DynamicResource TaskButtonTextBrush}" FontWeight="Bold" Margin="5,0,0,0" VerticalAlignment="Center" FontSize="12" />
</StackPanel>
</ControlTemplate>
Is it possible to create this image+text button using a control template, or do I have to go to a user control to do it? If it can be done with a control template, how do I set up the template bindings?

Answer 1

Define a CustomControl like this
in .cs
public class MyButton : Button
{
static MyButton()
{
//set DefaultStyleKeyProperty
}
public ImageSource ImageSource
{
get { return (ImageSource)GetValue(ImageSourceProperty); }
set { SetValue(ImageSourceProperty, value); }
}
// Using a DependencyProperty as the backing store for ImageSource. This enables animation, styling, binding, etc...
public static readonly DependencyProperty ImageSourceProperty =
DependencyProperty.Register("ImageSource", typeof(ImageSource), typeof(MyButton), new UIPropertyMetadata(null));
}
in generic.xaml of themes folder
<Style TargetType="{x:Type MyButton}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type MyButton}">
<StackPanel Height="Auto" Orientation="Horizontal">
<Image Source="{TemplateBinding ImageSource}" Width="24" Height="24" Stretch="Fill"/>
<TextBlock Text="{TemplateBinding Content}" HorizontalAlignment="Left" Foreground="{DynamicResource TaskButtonTextBrush}" FontWeight="Bold" Margin="5,0,0,0" VerticalAlignment="Center" FontSize="12" />
</StackPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
