DataViewBase.WaitIndicatorType Property

Gets or sets a value that specifies how async data loading operations are indicated within the grid. This is a dependency property.

Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v19.1.Core.dll

Declaration

C#

public WaitIndicatorType WaitIndicatorType { get; set; }

VB.NET

Public Property WaitIndicatorType As WaitIndicatorType

Property Value

Type	Description
WaitIndicatorType	A WaitIndicatorType enumeration value that specifies how async data loading operations are indicated within the grid.

Available values:

Name	Description
Default	Background operations are indicated within a dedicated indicator button. For the grid control, these operations are indicated within the Header Panel Button.
Panel	Background operations are indicated within a special panel displayed above a control.
None	Background operations are not indicated.

Remarks

The DXGrid control supports Instant Feedback UI Mode - an asynchronous mode. With this mode, you will no longer experience any UI freezing. Data operations will be performed asynchronously, in a background thread and both the Grid Control and your application will always be highly responsive. The user can continue to scroll through records, and even re-sort, re-group and re-filter the control’s data.

To provide visual feedback, the grid shows a wait indicator. Its type is specified by the WaitIndicatorType property. By default, background operations are indicated within a dedicated indicator button.

Set the WaitIndicatorType property to WaitIndicatorType.Panel to display a special panel above a grid control (see the image below). Its layout and appearance can be changed via the DataViewBase.WaitIndicatorStyle property.
