c# - ms ajax $find('clientID') keeps coming up with error -

i have modal extender called modal2 , when call

$find('modal2').show(); 

it comes classic error saying 'null' null or not object;

i searched google bit , made related controls visible testing purpose has not made difference.

any suggestions please?

thanks.

check client id; unless using clientidmode of static, like: ct100_contentplaceholder_modal2 , have do:

$find("<%= modal2.clientid %>") 

instead id.

hth.
