This tutorial combines some of the most useful features in the C1FlexGrid control to provide a dynamic view of a data table. The application starts with a simple data-bound grid containing sales data (from the NorthWind database), then adds the following features:

• Dynamic layout (column order)
• Automatic sorting
• Cell merging
• Automatic subtotals
• Outlining

The picture below shows what the final application looks like. The user can drag the first three columns to group the data by salesperson, country, and product name. When a column is dragged, the totals are automatically recalculated and the outline tree is rebuilt.
