Hello, You have to add "this.Refresh()" in the set of your property. All the best, Martin

You can only update the control in the UI thread. You'll need to use invoke, or some other method to update the text on the label.

I am using Asynchronous methods in my extern class and trying to update UI from these methods . I have created a delegate and delegate method in Form1 class and when I tried to invoke delegate from external class it says definition of invoke does't exist in current reference ... ??? What I m doing wrong here ? Thanks
