hi, experts.

would it be possible that i have asp text control and hook on onchanged event to client script at html page ? i've tried that...but couldn't get it work. cause i dont it to postback to server and can do online calculation on client browser. any solution other than using pure html text control ?

thank you.

i'm agree with zulu - if you choose such a scenario it is much easier to do it with javacript
the other solution is to make everything on the server, but then if your form contains a lot of controls it will be slow if you add autopostback to every control. so if you decide to make calculation on the server make them after you submit all the data

you can use Attributes collection of text control to add onchanged handler:

myTextBox.Attributes.Add( "onhange", "javascript:alert('It works!');" );

ooops, a typo, should be:

myTextBox.Attributes.Add( "onchange", "javascript:alert('It works!');" );

(and not 'onchanged' because it's not correct name of that event)
