How to run two Active Forms that pass data back and forth.

I am producing an application (C#.Net WFA) that has Form Members (FM) and Form Detailed Members (FDM). The former shows basic member details and the latter shows all member's details. FM displays a list of members while FDM shows individual members complete details. The FDM is involved by the user clicking on a member in FM. This not only starts Form Detailed Members but passes control to it, i.e the user cannot interact with FM until FDM is closed.

I want to change this behaviour so that both forms are active at the same time, which would allow the user to still be able to interact with FM while the details in FDM are refreshed when a new member is clicked in FM.

Can this and should this be done via threading ? Is there a more subtle method for this type of application.

Please note that FDM will be used to Update, Insert and delete members and hence data will be passed between both Forms in both directions.

Thanks you for your assistance.

Dear Bidyasagar,

Thanks for replying to my question. However, I think the title has misled you. The question is not about passing data back and forth between two forms.

It is about how to have two active forms available at the same time to the user.

This can be done if the application is started from the main by using ApplicationContext and Application Run. However, I want to invoke the second form from another form which in itself is initiated from a menu (yet another form).

The position has changed slightly now, The menu has a nunber of forms that similarly need to be available to the user at the same time. The user choses which two or more forms he needs to have running at the same time.

Thanks for your assistance.
