[dipak000]

Hi,
I have a non form class. I want to update label/ check status of check box etc.. in non form class ( here resides functions that contains logic). How can i do that ?

Labels, CheckBoxes etc. are graphical user interface controls that let the end user interact with your system.

If you do not have a form, then what do you have as a graphical user interface?

I have an form that contains label, 2 buttons and. Check box. I have separated a logic in to another class ( non form class ). I want to update the status of operation ( which is being executed in non form class) in to form label also activate some buttons. But not effective. I made all components public from private. Created an object of form class then accessed the elements. Ex :

formclass objformclass = new formclass ();
Objformclass.lbl1.text = " text updated";
similarly, objformclass.btn=true;

No error on compilation but not effective.

Well, you could implement the INotifyPropertyChanged Interface and raise property changed notification events every time a property is changed.

Then in your form's code-behind you could catch the property changed events and update the GUI controls that correspond to the property that was changed.
