Problem with access to control properties in Multibox

问题

I used multibox-component to create lightbox-similar div. But I faced problem. I placed textbox with id ‘tbx_position’ in that div. I entered some symbols in textbox and then tried to read value via javascript-function (it had to alert document.getElementById(‘tbx_position’).value). Every time that value was empty.

There is example of it.

Furthermore, if I place in the div asp:Button, server OnClick-eventhandler doesn’t catch fire. Is any idea, what’s reason? Thanks.

Try adding the <form> & </form> tags to your page.
