How to Develop TimeTable Dynamically in ASP.NET Appliction using C#.

HI All..
I want to develop a dynamic time table for a school.
But the subjects and periods are not fixed ...

so there can be any number of rows and columns in this which will be decided by user at runtime.

when user enters number of row and columns according to that, table layout will be displayed and Each cell of my Table will Contain a Textbox in which user can write somthing..

and when he clicks on save button the entire table will saved as it is....

should i use Gridview to accomplish my need ????
pls if u have any other better idea to develop this pls suggest me complete this task in a proper and rich way.....

thanks in advance
