C# Report Help

I am in desperate need to convert a template made in Excel to a report in C# ReportViewer. Requirement to calculate an employee's working hours based on working days and then obviously calculate the total hours worked in: Daily, Weekly and Monthly format. Also within the template you will see that I am in need of displaying all those employees that were late and by how many hours/ minutes/ seconds, so in total the requirements from this project are as follows: 1. Create a report that displays employee attendance (as shown in the template) 2. Create a report that shows ONLY those employees that were late (by how long/ total for the week/ month) 3. Ability to use parameters to define the search results (define: Name, Department & Date Range) Half of the job is done by me.. I only need report generation. Please only serious
