Put some fancy logic in your grid's summary row cells
By far the most popular widget for business apps created with Valence's Nitro App Builder is the Grid, with multiple options for rendering data cells. From simple display features like text alignment, currency/date renderers and conditional cell colors, to graphical images, formulas and conditional if/then logic using basic JavaScript -- just about anything on your IBM i system can be depicted in a user-friendly fashion using a Grid, and numeric values can be easily summarized by simply checking a box.
