Dashboard Customization

I created a dashboard. And I will need to add a button, and when I click on this button, I will need to call the vendor tracker and when I choose the vendor on the list, I will need to write the name on the textbox field. And when I refresh the dashboard, I take the good vendor name.

Thanks !

Does anyone know how to get information on a dashboard grid from
source code? I created a dashboard and i want to create a button that
launches another form. I am trying to get at a field in the selected
grid to populate the launched form with my selected data. Any
suggestions? the dashboard customizations are a little harder than
normal because I dont have access to all the information i normally do
on a regular form.
