How to delete all the rows at runtime in MAUI DataGrid (SfDataGrid)?

This article illustrates deleting all the rows at runtime in a .NET MAUI DataGrid. In this example, we’ll demonstrate deleting all rows through a button click.

Initialize the SfDataGrid with the required properties. Then, in the button click event, you can delete all records in the ItemsSource ObservableCollection by using the Clear function. The SfDataGrid will automatically refresh its view whenever you add or remove rows.

XAML:

<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
            xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
            xmlns:local="clr-namespace:MauiApp1"
            xmlns:datagrid="clr-namespace:Syncfusion.Maui.DataGrid;assembly=Syncfusion.Maui.DataGrid"
            x:Class="MauiApp1.MainPage">

   <ContentPage.BindingContext>
       <local:OrderInfoRepository x:Name="viewModel" />
   </ContentPage.BindingContext>

   <Grid>
       <Grid.RowDefinitions>
           <RowDefinition Height="Auto" />
           <RowDefinition Height="*" />
       </Grid.RowDefinitions>
       
       <Button Text="Delete All the Rows"
               Clicked="Delete_All_Button_Clicked"
               Grid.Row="0"
               Margin="0,10,0,10" />
               
       <datagrid:SfDataGrid x:Name="dataGrid"
                            ItemsSource="{Binding OrderInfoCollection}"
                            ColumnWidthMode="Auto"
                            Grid.Row="1" />
   </Grid>
</ContentPage>

MainPage.xaml.cs

namespace MauiApp1
{

   public partial class MainPage : ContentPage
   {
       
       public MainPage()
       {
           InitializeComponent();
           
       }

       private void Delete_All_Button_Clicked(object sender, EventArgs e)
       {
           if (viewModel.OrderInfoCollection != null)
           {
               viewModel.OrderInfoCollection.Clear();
           }

       }
   }
}
