AutoCompleteEditBase.WaitIndicatorColor Property

Gets or sets the color of the wait indicator. This is a bindable property.

Namespace: DevExpress.Maui.Editors

Assembly: DevExpress.Maui.Editors.dll

NuGet Package: DevExpress.Maui.Editors

Declaration

public Color WaitIndicatorColor { get; set; }

Property Value

Type	Description
Color	The color.

Remarks

If the LoadingProgressMode property is set to Auto, the editor automatically displays a wait indicator in the drop-down window when the text in the edit box changes, and automatically hides it when the ItemsSource collection is updated.

In Manual mode, use the IsLoadingInProgress property to show and hide the wait indicator. You can also use the WaitIndicatorColor property to specify its color.

Example

The code below handles the TextChanged event to supply suggestions.
