A string that specifies an expression used to evaluate values for the current column.
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.
The GridControl supports bound and unbound columns. Bound columns obtain their data from data fields of a grid's data source. Unbound columns are not bound to any field of the data source. These columns must be populated manually by handling the GridControl.CustomUnboundColumnData event or using the UnboundExpression property.
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.
We are updating the DevExpress product documentation website and this page is part of our new experience. During this transition period, product documentation remains available in our previous format at documentation.devexpress.com. Learn More...
