ASP.NET Timesheet project

I want to create a timesheet with C# .net . But it has some requirements . 1- Use Griview and bind it programatically. 2-And Change the column to row in gridview ( because the first-header row in timesheet shows activities which is a column in database table) First row and and first column comes from the db and the other rest of the fields shows textboxes and the last row shows total which calculates the total value of each row textboxes . the key point ; in this picture , date and day columns and in/out counts can be increased or decreased based on the database table values.. but i will use firstname and lastname instead of date and day / activitie1 ,activitie2,activitie3,activitie4,activitie5, so on . instead of in/out .And total calculates the percentage of textboxes value
