control inheriting from CompositeDataBoundControl doesn't retreive it's state information.

P: n/a
I have a control derived from ComposeteDataBoundControl. Control doesn't
retreive it's state information. I am going to frick out! What should I do
more?
I added two codes. One is for Default.aspx to Test the control
"SampleDataBound". When I click to the "Refresh" button here, the data
displayed in the SampleDataBound control become lost.
