Assembly: DevExpress.Xpf.Core.v24.2.dll

NuGet Package: DevExpress.Wpf.Core

#Declaration

public class LoadingIndicatorButtonInfo :
    ButtonInfoBase

#Remarks

The LoadingIndicatorButtonInfo class implements the functionality of a loading indicator displayed within the button editors (e.g., ButtonEdit, DateEdit, etc.).

#How to Add the Loading Indicator

Add a LoadingIndicatorButtonInfo class instance to the editor’s ButtonEdit.Buttons (ButtonEditSettings.Buttons for the in-place ButtonEdit) collection.

To display and hide the loading indicator, use its Visibility property.

#Example

The code sample below illustrates how to show the LoadingIndicatorButtonInfo during the long running operation and hide the loading indicator when the operation is complete.

<dxe:ButtonEdit
    AllowDefaultButton="False">
    <dxe:ButtonEdit.Buttons>
        <dxe:LoadingIndicatorButtonInfo Visibility="Collapsed" x:Name="loadingIndicator"/>
        <dxe:ButtonInfo GlyphKind="Refresh" Click="ButtonInfo_Click"/>
    </dxe:ButtonEdit.Buttons>
</dxe:ButtonEdit>
private async void ButtonInfo_Click(object sender, RoutedEventArgs e) {
    loadingIndicator.Visibility = Visibility.Visible;
    // Perform a long running operation instead of Task.Delay
    await Task.Delay(2000);
    loadingIndicator.Visibility = Visibility.Collapsed;
    e.Handled = true;
}
