I want the user to generate a postback event when leaving a div, that is, the onmouseout event. How do I do that?

<div onmouseout="document.forms[0].submit();">

</div>

First of all, determine who to send back to? !

Assuming that a button is triggered, you can write:
  thePanel.Attributes["onmouseout"]=
    this.Page.ClientScript.GetPostBackEventReference(theButton,"");

Suppose it is in a control, especially in ascx or aspx to define the triggered background code, then you can use the IPostbackEventHandler interface for your user control or page type (it actually only defines a method), and then write the code to let the customer Trigger it at the end:
  thePanel.Attributes["onmouseout"]=
    this.Page.ClientScript.GetPostBackEventReference(this,"");

IPostbackEventHandler is the key to post back a server program and script. GetPostBackEventReference and GetPostBackClientHyperlink are the functions you use to generate script code.

You can search for the usage of IPostbackEventHandler, GetPostBackEventReference, GetPostBackClientHyperlink.
