For me it is easier to have the linkbutton and "the other thing" ready. Just
set their visibilities and properties. But maybe in your case it is
something more complex, so if it works this way - fine.

If the panel is Visible = false, it and all its child controls are not
rendered to the client, so there will be no load.
On the button click load the DropDownList with the values and set the panel
Visible=true. Then on the DropDownList SelectedIndexChanged event set it
Visible = false again.
Hope this helps
