Editing of Assignment Blocks

Hi ,
I am having a component A where B is my overviewpage.

In B,

I have associated many views. (for example)

View 1 (Header) component X1 view Y1  (X1/Y1)

View 2               component X2 view Y2 (X2/Y2)

View 3               component X3 view Y3 (X3/Y3)

I have added an edit button to View B.

On click of the edit button, all the sub view which are there in my overview page should turn editable..

Have added the below code in my edit button event handler.

me->view_group_context->set_all_editable( ).

lr_vgc ?= view_group_context->get_dependant_vg_context( ).

lr_vgc->set_all_editable( ).

I can see a few fields editable and few fields not.. but if i directly press header edit, there are many fields which are editable..

Please help me out of this issue.

Thanks
Regards
Praveen
