ASP.Net我应该使用哪种网格控件以及如何使用它？

I have been asked to write a grid which tracks flexitime for employees. There are 4 weeks in a period, and we only count the working days for each week. On the verticle axis is day of the week; Monday to Friday, am and pm. On the horizontal axis is the 4 weeks, which are subdivided by time in, time out and number of hours for each day am and each day pm. Then there are total hours for each week, and a carried forward for each week. These have to be kept up to date if a user edits a time. The user can enter and edit the times in each cell. He may put in the number of hours, or he may enter a leave type from a ddl. Because of the complexity of this, either entering a time or selecting an entry in a drop down, I would like to enter the selection in a popup window, although I am open to other ideas. Now if I were using a Gridview, I could have an select button. However that would apply to the whole role. The problem is is that if I select Monday am, I would be selectin Monday am for all 4 weeks, rather than the one I am interested in. So should I use a LIstView instead? And should I use JQuery for client side popups? If i did, would I be able to update the total fields for each week as well? Look forward to hearing from you.I have been asked to write a grid which tracks
