Hello,

For a client I have to implement a scheduling module. The purpose of this module is to link crewmembers to jobs available. It has to work as follows:

- Vertically there is a row shown for each job in the database
- Horizontally, there are a few columns with job info (date, name). Following those columns is a column for each crewmember in the database. These columns are dynamically generated on initialisation.
- By clicking one of the fields in the grid, the user of that column is linked to the job of that row. Links made are indicated by a different background color of the cell.

I'm using the UltraWebGrid (8.1 release) to implement this. Getting the correct rows and columns shown isn't a problem, but performance is. For some reason, on every postback (the user clicks a matrix field to link a user to a job) the grid is databinding again. That takes a while and thus slows the whole thing down.

The only thing I want to do when a user clicks a cell is enable or disable the correct link in the database. I don't get why all the data has to be reloaded. Also, even with AJAX functionality enabled, the grid is causing an entire postback. I could prevent that with an extra WARP offcourse, but I don't understand why it's doing this in the first place.

How can I implement this in a way the performance meets up to my clients expectations?
