Yes, but a lot depends on how much time you have and how much you are willing
to commit to get this done.
I created a project from scratch that fundamentally perform the task you
suggested the way I did it was to place a gridview and button on a page then
perform a little magic as show below
Essentially create a datatable with the rows as show then add a new row to
the datatable and set editindex to the row. Of course you need to know the
row number or perform some magic so your new row show on top then you can set
editindex = 0.
For my example I added a command field through the wizard but even this can
be done programmatically. The add button while external for the example
could easily made in to a template field to make it part of the grid.
The more you customize the harder it gets especially if you doing it for the
first time. If you doing this for something you have to deliver soon then I
suggest exploring the third party community for a solution. But if you have
time or just exploring have at it is fun.
Regards
ps
The example is not complete by any means it just shows the approach you
could take and is not a complete solution.
