I have multiple grid forms on a page and I want to hide them when the page is loaded and before a search is done.

If no records were found, don't show the gird. I have tried few codes like the one below but it doesn't work.

Any idea of what works. Please help.

$<form>before_show_event:

global $employees1;
$p=CCGetParam("emp_id",0);
if ($p > 0)
{
$employees1->Visible = True;
}
else
{
$employees1->Visible = False;
}

Thanks,
Ahaa

Do that in the PAGE's Before Show event and it will prevent the data from
being fetched (the grid's beforeshow event is too late, it's already been
fetched in the grid's class initialization ). I don't know how to
interprete " $<form>before_show_event:, because your code should be in a
function that says "function Show()". Are you actually declaring the event
handler through the properties panel of the IDE, or just trying to write the
code yourself?

Hi Donb,

Thanks for your response. There's no custom function involved, its all inthe IDE. I have tried the code in the page before_show_event and the grid form got hidden when there's no record. But after a search is done and there's data in the recordset, the grid did not show again.

Can you please show me how I can show the grid when there's record for the grid after a search is done.

Thank,
Ahaa

if (CCGetParam("parameter1","?") != "?") {
$mygrid->Visible = false
}
else {
$mygrid->Visible = true;
}

Note: You will probably have several parameters that should be checked, like
"parameter1" is checked in my example. Just "or" them into the "if"
expression. I use the "?" so that the test distinguishes between the case
where the parameter is declared but empty from the case where the parameter
is not declared at all (in the URL string). This may or may not matter to
you.

Put this in the page Before Show event and it will do what you want.

Your code relies on a URL variable (like
http://www.toto.com/mypage.php?emp_id=0), not on the actual content of
the form. Is it on purpose?
