Steps:
1. Get the 'To' date and 'From' date from the datepicker controls.
2. These dates are parameters to the query that will fetch data. Now query can be part of report or query data directly can be used in report
3. In query:
SELECT * FROM DailyReport WHERE DateInput BETWEEN @FromDate AND @ToDate
This query would return you the needed data. Use the data in your report and display it.
