Preventing the opening of a form on a add button click

Question

Did you guys know how to prevent the open of a Form when I click on a add button?

Maybe using beforeShowForm?

function(formid)
{
    if(jQuery(\'#gri

Cool, tks Oleg!!! BTW, I came with another(but not beautifull) solution:

** This is a aftershowform action. If we do not have a selected row on the main grid(#gridap), we hide the form modal with jqmHide(). Then, I use your solution to show the alertcap.

$closeform = <<< CLOSEF
function(formid)
{
    if(!jQuery('#gridap').getGridParam('selrow'))
    {
        $('#editmodgridbal').jqmHide();
        viewModal('#alertmod', { gbox: '#gbox_', jqm: true });
    }
}
CLOSEF;


$grid->setNavEvent('add','afterShowForm',$closeform);
