installer

I want to create a single installer for some web applications using InstallShield 2010.

Each application is a component of a feature. For each component I have some Custom Dialogs wich I created for save some configurations like connection string.

My question is how to navigate through this dialogs according the features I selected to install.

I think I have to edit the behavior of buttons in the dialog but I don't know what I have to write in Event, Argument and Condition.

I try to find some informations in InstallShield User Guide but it didn't help me.

Thanks for your time!
