Update one panel using another panel but return the rendered content of changed panel only

I just got a form in modal popup extender and It want it to work like below,

1.Submit, Cancel buttons to close the modal popup are inside updatepanel1

2.There is a label inside the TargetControlPanel Panel1 which is inside updatepanel2

3.The Submit works async as it is inside the updatepanel1, exactly as i wanted it to. Also Displaying the result of submit in label too works as expected. BUT, i want the response to return only the rendered result of updatepanel2, actually the rendereded result of the both updatepanel1 and updatepanel2 are开发者_开发技巧 returned.

I just got a load of event handlers on the cancel button which are getting replaced due to the update from updatepanel1` and i don't use jQuery. So adding event handlers is what i don't want to do again. and thats why this question popped up.

LOL How stupid, i could have thought about this 5 minutes more to get the answer.

Here is what i did:

<modal popup extender></modal popup extender>
<target Button></target button>
<target panel>
<blah blah blah/>
<updatepanel>
<label result>
</updatepanel>
<blah blah blah/>
<updatepanel2>
<button submit/>
</updatepanel2>
<button Cancel>
</target panel>

That's a Pseudocode , by putting the cancel button outside the updatepanel i had nothing to lose there sweet
