Where to write the code for modalpopupextender Popup when a link is clicked for asp.net (VS 2005)

Question

Hello Guys,

I am trying to get a popup when a link is clicked. I have no idea where i should place the code for modalpopupextender in the code. Does the code has to be written along with the link button. I get many errors like "An extender can't be in a different UpdatePanel than the control it extends" and many such. Please someone help me out by reviewing the code. I really appreciate for all of you for sparing some time. Thanks so much!

<td colspan ="2" style="width: 64px">
    <div style="float:left; padding-left:9px;">
