Updating values in a Grid template

I'm using xMII 11.5 SP3. Can values displayed in a grid template be edited directly in the template? We have an application where we'd like to pull values out of a SQL Server table, display them in a grid and have the user update the numbers then push the updated numbers back into the table. In a similar application I display the values in a grid then enter the updated numbers through an HTML form directly below the grid. It works but it scores low on the elegance scale.

Thanks for your help!
