Hi Mario,

In the Page_Load method add the following code, tweaking it to fit your control and javascript function:

MyControl.Attributes.Add("onchange","myfunction(parm1,parm2,parm3);");

In the javascript function add the following to call the postback:

__doPostBack('MycontrolID','')

>I have a lot of controls...and in runtime i need asign&run custom server validators.
>
>For example, i have a edit. In this, the user write a code, like "1". Then, i need go to the server (i need post the whole form in this case), run a function inside a dll made by the user, get the data and re-asign the data to the form, show error&warning if any, and put the validity of the form as well... But with this control, i need do a little of jscript here becuase is pluged with a combo, and if the data is not in it, then i need show another form and cancel the process...
