HI, ive got a strange question.
 
i have an aspx site with a repeater on it. The repeater doesn't work properly.
the first 2 pages works perfectly. The third and further doesn;t snow any result, but my datasource wich is used as the repeater datasource contains 10 items. Why isn't it showing in my page ????
 
Here is my code. and some extra information.
total amount of users is 1079.
10 users are shown on a page. so 1079/10 + 1 = 108 pages.
page 1 works fine
page 2 works fine
page 3 and futher don't show results.
