Remarks
Important
This documentation topic describes legacy technology. We no longer develop new functionality for the GridControl and suggest that you use the new DataGridView control instead.
See the Unbound Columns topic for detailed information on unbound columns in GridControl.
Example
This example shows how to create and customize grid columns for displaying and editing data of different types (text, numbers, dates and Boolean values). The specified collection contains columns bound to the data source fields (Product.Name, Product.UnitPrice, Quantity, Date and Shipped) and one unbound column (Total) displaying data values calculated according to a formula based on the values of other columns.
The image below illustrates the result.
