Thread safe Dependency Property in WPF

Question

Hello everyone,

 

I am working on a WPF project and found an issue ot thread calls.

 

I have a Dependency Property of a usercontrol as below

 

public bool IsON
        {
            get { return (bool)GetValue(IsONProperty); }
            set { SetValue(IsONProperty, value); }
        }

When I access this property, an exception occurs  "The calling thread cannot access this object because a different thread owns it"

 

I tried lock function with a readonly object but no luck.

Is there any solution to make it thread safe on user control side and not from the calling class because I want to handle it from usercontrol side, as the property was used several times

 

Thanks

Devendra
