EDITED::

If you want your modal popup to be displayed when the user clicks on the btn_Add_Task button, you should set that button as the TargetControlID of the extender:
<cc1:ModalPopupExtender ID="btn_Add_Task_ModalPopupExtender" runat="server"
TargetControlID="btn_Add_Task" PopupControlID="pnl_Add_Task"
BackgroundCssClass="modalBackground" DropShadow="True" />
In your current code, the modal popup is triggered by a button named Dummy_btn, which I can't find in your markup, but which probably isn't what you want.
We had many issues with ajax popup. you might want to try the approach we have been using for past one month or so with out any issues. This approach creates a popup with out need of ajax / jquery / javascript /css/ update panel .
here: A modal popup with out using ajax, update panel, jquery or javascript- surprisingly this seems to work
