Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v14.2.dll

Declaration

C#

[XtraSerializableProperty]
public bool AllowCascadeUpdate { get; set; }

VB.NET

<XtraSerializableProperty>
Public Property AllowCascadeUpdate As Boolean

Property Value

Type	Description
Boolean	true to allow cascading data updates; otherwise, false. The default is false.

Remarks

By default, when a view is vertically scrolled, the grid (or treelist) synchronously loads all nodes that should be displayed on screen. To speed up the grid's (or treelist's) performance, enable the AllowCascadeUpdate option. In this instance, visible nodes are asynchronously loaded, one by one, in a background thread. To provide visual feedback, the grid (or treelist) plays an animation while the data is being retrieved.
