How to show Busy Indicator while loading data in .NET MAUI DataGrid?
The .NET MAUI DataGrid (SfDataGrid) allows you to show a SfBusyIndicator while loading Data in the DataGrid. The busy indicator can be enabled and disabled by using the IsRunning property.
C#
In behavior class, set the ViewModel.IsLoading property value to true and false based on items generation using the loaded event.
public class MainPageBehavior : Behavior<ContentPage>
{
SfDataGrid dataGrid;
ViewModel viewModel;
protected override void OnAttachedTo(ContentPage bindable)
{
base.OnAttachedTo(bindable);
dataGrid = bindable.FindByName<SfDataGrid>("dataGrid");
viewModel = (ViewModel)bindable.BindingContext;
dataGrid.Loaded += DataGrid_Loaded;
}
private async void DataGrid_Loaded(object sender, EventArgs e)
{
this.viewModel.IsLoading = true;
await Task.Delay(6000);
this.viewModel.GenerateOrders();
this.viewModel.IsLoading = false;
}
protected override void OnDetachingFrom(ContentPage bindable)
{
base.OnDetachingFrom(bindable);
dataGrid = null;
viewModel = null;
dataGrid.Loaded -= DataGrid_Loaded;
}
}
XAML
Bind the value of the ViewModel.IsLoading property to SfBusyIndicator.IsRunning property to enable or disable the busy indicator in the view until items are loaded in the view.
