EmptyView in MAUI DataGrid (SfDataGrid)

The SfDataGrid provides options to display and customize an empty view when no data is available to display using the following properties,

• EmptyView object can be set to a string or view when SfDataGrid has no items. The default value is null.
• EmptyViewTemplate is used to customize the appearance of EmptyView. The default value is null.

Display a string when DataGrid has no items

We can specify the EmptyView property to a string that will be shown when the ItemsSource property is null or when the collection that the ItemsSource property specifies is empty or null.

MainPage.xaml

<syncfusion:SfDataGrid x:Name="dataGrid"
                         ItemsSource="{Binding OrderInfoCollection}"
                         EmptyView="No records">
</syncfusion:SfDataGrid>

MainPage.xaml.cs

dataGrid.EmptyView = "No records";

Display views when DataGrid has no items

The EmptyView property can be set to a view, which will be displayed when the ItemsSource property is null, or when the collection specified by the ItemsSource property is null or empty.

MainPage.xaml

<syncfusion:SfDataGrid x:Name="dataGrid"
                       ItemsSource="{Binding OrderInfoCollection}">
    <syncfusion:SfDataGrid.EmptyView>
        <StackLayout HorizontalOptions="Center" VerticalOptions="Center">
            <Label Text="&#xE7A4;" FontSize="20" TextColor="Black" FontFamily="MauiMaterialAssets.ttf"/>
            <Label Text="No records" FontSize="14"/>
        </StackLayout>
    </syncfusion:SfDataGrid.EmptyView>                   
</syncfusion:SfDataGrid>

MainPage.xaml.cs

StackLayout stackLayout = new StackLayout() { HorizontalOptions = LayoutOptions.Center };

var label1 = new Label()
{
    Text = "\uE7A4",
    FontSize = 20,
    FontFamily = "MauiMaterialAssets.ttf",
    HorizontalTextAlignment = TextAlignment.Center,
};
var label2 = new Label()
{
    Text = "No records",
    FontSize = 16,
    FontFamily = "Roboto-Regular",
    HorizontalTextAlignment = TextAlignment.Center,
};
stackLayout.Children.Add(label1);
stackLayout.Children.Add(label2);

dataGrid.EmptyView = stackLayout;

NOTE

The view that the EmptyView displays may be a single view or a view that has multiple child views.

Display a DataTemplate when DataGrid has no items

We can set the EmptyView to a custom type that will displayed when the ItemsSource is null or the collection that the ItemsSource parameter specifies is empty or null. The EmptyViewTemplate can be used to modify the EmptyView’s appearance.

MainPage.xaml

<ContentPage xmlns:syncfusion="clr-namespace:Syncfusion.Maui.DataGrid;assembly=Syncfusion.Maui.DataGrid"
             xmlns:local="clr-namespace:EmptyViewTemplate">
    <StackLayout>
      <SearchBar x:Name="filterText" 
        FontSize="16"
        Placeholder="Filter Inventory" TextChanged="filterText_TextChanged"/>
      <syncfusion:SfDataGrid x:Name="dataGrid"
                    ItemsSource="{Binding OrderInfoCollection}">
          <syncfusion:SfDataGrid.EmptyView>
              <local:FilterItem Filter="{Binding Source={x:Reference filterText},Path=Text}" x:Name="filter"/>
          </syncfusion:SfDataGrid.EmptyView>
          <syncfusion:SfDataGrid.EmptyViewTemplate>
              <DataTemplate>
                  <Label Text="{Binding Source={x:Reference filterText},Path=Text, StringFormat='{0} is not found'}"
                        HorizontalTextAlignment="Center"     
                        VerticalOptions="Center"
                          FontSize="14" FontFamily="Roboto-Regular"/>
              </DataTemplate>
          </syncfusion:SfDataGrid.EmptyViewTemplate>
      </syncfusion:SfDataGrid>
  </StackLayout>
</ContentPage>

MainPage.xaml.cs

dataGrid.EmptyView = new FilterItem() { Filter = filterText.Text};

dataGrid.EmptyViewTemplate = new DataTemplate(() =>
{
  Label label = new Label()
  {					
    FontSize = 18,
    FontFamily = "Roboto-Regular",
    VerticalOptions = LayoutOptions.CenterAndExpand,
    HorizontalTextAlignment = TextAlignment.Center
  };
  label.SetBinding(Label.TextProperty, new Binding(source:filterText, stringFormat: "{0} is not found", path:"Text"));
  return label;
});

The FilterItem type defines a Filter property.

FilterItem.cs

public class FilterItem : BindableObject
{
  public static readonly BindableProperty FilterProperty = BindableProperty.Create(nameof(Filter), typeof(string), typeof(FilterItem), null);

  public string Filter
  {
      get { return (string)GetValue(FilterProperty); }
      set { SetValue(FilterProperty, value); }
  }
}

FilterItem object is set to the EmptyView property, and the Filter property is bound to the SearchBar.Text property. When SearchBar.TextChanged event is raised, the value of the SearchBar.Text property is stored in the Filter property.
