Adding a data grid within a existing form

[Mkaith]

Hi, My use case is that i have a parent form and a contacts form. When i press addcontact button a pop up is opened and contact form is rendered within it. Once i have filled that form is there any way to dynamically show that info above the addcontact button in the form of grid.

Also if i perform some actions through custom events then my form is again rendered and i need to fill that all again. Is there any way to retain all those values.

Thanks
