How to add custom XAML attributes to a class that inherits UserControl?
I have a custom UserControl and I want to give it a custom property "MyProperty"
which I can set in XAML. So that my XAML will look like this:
<EventDet:EventAddressControl
MyCustomProperty="formattype"
x:Name="EventSessionLocationContr开发者_如何学编程ol"/>
How do I give the UserControl a custom attribute / property which I can then set in XAML?
If you are using CLRProperty you cannot use for Binding purpose.
public partial class MyCustomControl : UserControl
{
public MyCustomControl()
{
InitializeComponent();
}
public string MyCLRProperty { get; set; }
public string MyProperty
{
get { return (string)GetValue(MyPropertyProperty); }
set { SetValue(MyPropertyProperty, value); }
}
// Using a DependencyProperty as the backing store for MyProperty. This enables animation, styling, binding, etc...
public static readonly DependencyProperty MyPropertyProperty =
DependencyProperty.Register("MyProperty", typeof(string), typeof(MyCustomControl ));
}
<my:MyCustomControl MyProperty="{Binding BindingProperty}"
MyCLRProperty="MyCLRProperty"/>
Just put a normal DependencyProperty in your class.
If you just want to set the value from xaml then you can use a regular property. If you want to use the property with triggers, styles, etc then you would need to use a dependency property to take advantage of those WPF features
