<asp:postbacktrigger controlid="Button7" xmlns:asp="#unknown">

I think you need the eventname="click" in the trigger'

Or because the button is inside the update panel, the ID name is prefixed with something like $CT_100_button7

Try in the button

<asp:button xmlns:asp="#unknown">
ID="Button7" 
ClientIDMode="Static" 
runat="server" 
CausesValidation="False"  
onclick="Showbutton_Click"
style="z-index: 1; left: 7px; top: 123px; position: absolute" 
Text="Show" />
</asp:button>
