I need to create a custom property meaning rather using
<Style x:Key="ABC" TargetType="Rectangle">
<Setter Property="Fill" Value="Red"/>
</Style>
I like to have something like Rectangle and assign it an ID so later when it is dropped on Canvas I can retrieve its ID.
<Style x:Key="ABC" TargetType="Rectangle">
<Setter Property="Fill" Value="Red"/>
**<Setter Property="ID" Value="1234567890-ABC"/>**
</Style>
How can I define that custom property?
Regards, Amit
Define a custom attached property in a separate class:
public class Prop : DependencyObject
{
public static readonly DependencyProperty IDProperty =
DependencyProperty.RegisterAttached("ID", typeof(string), typeof(Prop), new PropertyMetadata(null));
public static void SetID(UIElement element, string value)
{
element.SetValue(IDProperty, value);
}
public static string GetID(UIElement element)
{
return (string)element.GetValue(IDProperty);
}
}
Then you can use this:
<Setter Property="local:Prop.ID" Value="1234567890-ABC"/>
local
must be defined in the root element of your XAML appromimately like this:
xmlns:local="clr-namespace:AttPropTest"
where AttPropTest
is the namespace of the assembly.
In code, you can determine the ID with Prop.GetID(myRect)
.
