A grid's column collection.
public class GridColumnCollection : ObservableCollection<GridColumn>
Public Class GridColumnCollection Inherits ObservableCollection(Of GridColumn)
The grid stores its columns within the GridControl.Columns collection. The GridColumnCollection class provides methods that can be used to add, delete, or access individual columns and perform other common collection management tasks. Individual columns are represented by the GridColumn class descendants and can be accessed by their field name or using indexed notation.
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.
