Does anyone know about "Page_ClientValidate()" javascript client-side

function. my one of the WebForm generates a HTML code like this for a

button:



<input type="submit" name="bSubmit" value="Go" onclick="if

(typeof(Page_ClientValidate) == 'function') Page_ClientValidate(); "

language="javascript" id="bSubmit" class="buttonStyleUp" />



I think we can write client-side codes into Page_ClientValidate, because

there won't be any function named like this if you don't write one.



But I can't do this again. My other WebForms can't generate a HTML code 

like

this.



Do you have any detail information about this subject?
