How to show Busy Indicator while loading data in MAUI DataGrid?
The .NET MAUI DataGrid(SfDataGrid) allows you to show a SfBusyIndicator while loading Data in DataGrid. The busy indicator can be enabled and disabled by using IsRunning property.
C#
In behavior class set ViewModel.IsLoading property value to true and false based items generation using 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 ViewModel.IsLoading property to SfBusyIndicator.IsRunning property to enable or disable busy indicator into the view until items loaded in the view.
