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...

So, i put in a jscript function:

function AsignarSeleccionado(combo,edit,postback){
edit.value=combo.value;
if (postback==true) {
//window.Form1.submit();
__doPostBack(combo.id,"");
}
}

That work well, but when the form is posted to the server, the OnChange event of the edit is not fired. I try implementing IPostBackEventHandler.RaisePostBackEvent but the server not fire this event...

I need a way to solve it. in short:

- From a JSCript code, fire the postback
- In the server, catch that i do a postback from x control
- Run the custom code, rebind and back.

Also, i don't see how put optionaly the fire event (that it, put this process in some controls and in others not)

Thank for your time...
