Room scheduling system

The manual room scheduling in our school is a little messy and prone to conflicts so I am thinking of making a room scheduling program for them. The attached screenshot is what the GUI should look like (other suggestions are welcome). The main thing is that no time should overlap with one another, I think I can do that with SQL.

For the GUI part, what do you think can I use for such design?

TIA

Looks pretty much like a grid to me. Given the forum this is posted in, I assume you're using WPF? If so, you've got the Grid control.

What else is it supposed to do? That will really determine what's most appropriate (i.e. although I mentioned Grid just now, if you're adding/removing rows dynamically, Grid might not be your best option)
