ColumnBase.Binding Property

Gets or sets the binding that associates the column with a property in the data source.

Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v21.1.Core.dll


public BindingBase Binding { get; set; }

Property Value

Type Default Description


A BindingBase object representing the data binding for the column.


The Binding property allows a column to specify a property of the grid control’s DataControlBase.ItemsSource to bind to. Note that the data source should implement INotifyPropertyChanged to notify the grid control that a property value has changed.

The attributes-based validation does not work when using the Binding property.

Columns bound to data using the Binding property are read-only by default. Set the binding’s Mode property to TwoWay to enable editing.

To bind a column to a property using the RelativeSource or Source binding, create a ColumnBase.CellTemplate for this column and define the binding within it.


When working with data structures that contain Dynamic Objects, use the Binding property instead of ColumnBase.FieldName.

Columns that are bound using the Binding property might work more slowly than columns that use the ColumnBase.FieldName property.

When the Binding property is specified, the ColumnBase.FieldName property should not contain an existing property name.

Setting the Binding.UpdateSourceTrigger property for the binding passed to the Binding property has no effect. Use the DataViewBase.EnableImmediatePosting to control how the cell values are actually posted.

When a GridColumn is bound using the Binding property, the GridControl automatically initializes its ColumnBase.FieldName property with a value generated based on the specified binding expression to properly recognize columns. If you are using a similar binding expression for your columns, to avoid problems with column recognition, set unique ColumnBase.FieldName values for your columns with Binding (the FieldName property value should not refer to an existing data source property).


<dxg:GridControl x:Name="grid">
                <dxg:GridColumn Header="Id" FieldName="col1" Binding="{Binding Path=Id, Mode=TwoWay}"/>
                <dxg:GridColumn Header="First Name" FieldName="col2" Binding="{Binding Path=FirstName, Mode=TwoWay}"/>
                <dxg:GridColumn Header="Last Name" FieldName="col3" Binding="{Binding Path=LastName, Mode=TwoWay}"/>
                <dxg:TableView Name="View"  ShowAutoFilterRow="True" NewItemRowPosition="Top" AllowPerPixelScrolling="True"/>


The ColumnBase.FieldName or Binding (that also sets ColumnBase.FieldName internally) properties must be defined for every GridControl column.
