Assembly: DevExpress.Mobile.Grid.v18.2.dll

public interface IAndroidRefreshCustomizer

Public Interface IAndroidRefreshCustomizer

Remarks

To customize the color of the Android refreshing bar, use the IAndroidRefreshCustomizer.BarColor property of the object that implements the IAndroidRefreshCustomizer interface.

Examples

This example demonstrates how to customize a color of an indicator (icon or bar) shown when GridControl refreshes cell data.

Grid_RefreshingIndicators

To change the color of a refresh indicator, perform the steps below.

Activate a grid's pull-to-refresh functionality. For this purpose, assign true to the GridControl.IsPullToRefreshEnabled property.
Use the ThemeBase class's properties to access customizers used to change an indicator's color on different mobile platforms. In this example, the following customizers are used.
- ThemeBase.AndroidRefreshCustomizer
- ThemeBase.IOSRefreshCustomizer
Apply the customization by calling the ThemeManager.RefreshTheme method.
