Member name in code-behind of the Page, should match to the ID of the
control.

If your user control is:

<uc1:testCtrl id="TestCtrl1" runat="server"></uc1:testCtrl>

it's code-behind member should be

public testCtrl TestCtrl1;

I don't see the coee-behind class for the UC itself, but hopefully you have
the custom event (SearchTitle) declared there and so forth.
