If use UpdateMode="Conditional" more log the behind a into the Page_Load

Table1 write 1 record

If rptList have 2 record: table2 write three records

If rptList has four records: table2 write 5 records

Whether log or breakpoint that btn4_Click performed only once but table2 write multiple records incredible
