Forms Data Controls :: FormView And GridView In One Page?

In my webpage I have a Formview bounded by sqldatasource. I can perfectly Update data from it. In the same page I have a gridview bounded by some other sqldatasource. I have to give user new record option from gridview.

I know that there is no default property to insert new record with the help of gridview until we provide some other way by coding but I don't want to do that.

Therefore I have taken a textbox with the validation field and a button outside the gridview to insert new record into gridview and refresh it.

I don't want to allow user to add empty text using textbox thatswhy I have validated that textbox.

Problem:

If user has the scenario to update only the Formview then he cannot because there is a validation there with the textbox.

If I remove the validation then user is able to update FormView perfectly but may add empty text from the textbox.

if the user allowed to update FormView and to add data with the help of textbox and gridview get refresh. If user can do only one task also either to update FormView or to add data from textbox to refresh gridview.

The task is most important for me and I have only 12 hours to complete this task or you can say the time limit is going to expire.
