GridControl.Columns Property

Provides access to the grid’s column collection.

Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v18.2.dll

Declaration

C#

public GridColumnCollection Columns { get; }

VB.NET

Public ReadOnly Property Columns As GridColumnCollection

Property Value

Type	Description
GridColumnCollection	A GridColumnCollection object that represents a collection of columns within the grid.

Remarks

The grid stores its columns within the Columns collection. This collection provides methods that allow you to add new and remove existing columns. Individual columns are represented by GridColumn objects, and can be accessed using indexed notation or by the field name (ColumnBase.FieldName).

In Card Views, columns contained within the Columns collection correspond to card fields. In Table Views, they are displayed as columns.

To access only visible columns whose BaseColumn.Visible property is set to true, use a view’s GridViewBase.VisibleColumns property.

To learn more, see Columns and Card Fields and Creating Columns and Binding Them to Data Properties.
