Just create a javascript function and execute the generated postback event:

<%=ClientScript.GetPostBackEventReference(myUpdatePanel, "")%>

The above statement is put on your aspx page, and it references the exact same code generated from the server to cause a postback for your panel. You can use it by putting it inside a function on the client side:

function fncUpdatePanel () {
    <%=ClientScript.GetPostBackEventReference(myUpdatePanel, "")%>;
}

Then you can attach that function to any event on your page (even a mouseover event). This example uses a server side to attach the event:

myUpdatePanel.attributes('onmouseover', 'fncUpdatePanel()')
