Calendar control

I am busy evaluating your grid control and have a couple of questions. We are developing an input form in a grid-like manner. The user enters a row of data at a time. When they complete the row they can decide to add another row in which case the grid adds another row dynamically or they can delete an existing row.



The individual columns of data captured are very different. To start with we need a select box, pre-populated and on selection the values of another select box need to be dynamically updated. I have seen something along the lines of the combo control integrated with the grid, although the documentation is a bit poor.



We also require the use of our own calendar widget. Is it possible to integrate it somehow using the eXcell functionality?



Thank you
