I am making a custom control based on a button, and I want to bind the width of the button to a property of the class. I have looked at this, this, and this, but they either aren't what I'm looking for, or don't work.
Generic.xaml
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:CustomControl">
<Style TargetType="{x:Type local:MyCustomControl}" BasedOn = "{StaticResource {x:Type Button}}">
<Setter Property = "Background" Value = "LightSalmon" />
<Setter Property = "Foreground" Value = "Blue"/>
<Setter Property = "Height" Value = "50"/>
<Setter Property = "Width" Value = "{Binding MyCustomControl.TextBinding}"/>
<Setter Property = "VerticalAlignment" Value = "Top"/>
<Setter Property = "Margin" Value="10"/>
</Style>
</ResourceDictionary>
MyCustomControl.cs
namespace CustomControl
{
public class MyCustomControl : Button
{
double m_textBinding = 50;
public double TextBinding
{
get { return m_textBinding; }
set { m_textBinding = value; }
}
static MyCustomControl()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(MyCustomControl),
new FrameworkPropertyMetadata(typeof(MyCustomControl)));
}
}
}
If need be, I can just use the "setter" function, and specify manually, "Width = value;", but I would prefer to use a binding. Currently the "{Binding MyCustomControl.TextBinding}" isn't working.
This should work:
<Setter Property="Width"
Value="{Binding TextBinding, RelativeSource={RelativeSource Self}}"/>
