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.v24.2.Core.dll

NuGet Package: DevExpress.Wpf.Grid.Core

#Declaration

public WaitIndicatorType WaitIndicatorType { get; set; }

#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.

InstanceFeedback_DefaultWaitIndicator

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.
