Yashodhan,

Do you have the expression below as the value assigned on the property sheet?

If so this expression will be evaluated only the first time any form derived from this class is instantiated, every other form will get the value from this first instantiation.

If you want the value to be properly evaluated every time a form instantiates you should move that evpression into the Init() method of the class.

>If I create a property in the class form and assign the value to it, I am not getting that value in the form created with this base form. I am assigning the following value with the help of expression builder.
