Hey guys,I'm working on an windows application for an institute, let me elaborate a bit,It gets the hours for classes (7-8:30, 9-10:30 ...) and also number of classrooms ( 1, 2, ....) then using these two collection of data I want to create a schedule like Sunbird, I have hours and classrooms therefore there is a vertical column (classrooms) and horizontal columns (hours).what I have in mind is to create a 2*2 matrix and each cell will have id and that way I can check the status of it, but how can i display it visually ? I can't use datagridview, and this is dynamic so I can't pre-define the cells.what do you suggest for this ?I'm open to new suggestions, maybe you've got a better idea than I do. see we have the hours (which is taken form one table) and class rooms ( which is taken from another table)so I dunno how many I'm going to have, I guess I have to get these values from the user then dynamically create a new table with these info.regards,K1
