Hi Rafael, 

  

Thank you contacting Syncfusion support. 

  

You can use ItemsSourceChanged event which fires whenever the ItemsSource has been changed. Please refer our User Guide documentation regarding the same, 

 

UG link: https://help.syncfusion.com/xamarin/sfdatagrid/grid-events#itemssource-changed-event 

  

Please refer the following code snippet, 

  

  

public MainPage() 

{ 

    InitializeComponent();                                             

    dataGrid.ItemsSourceChanged += DataGrid_ItemsSourceChanged; 

} 

  

private void DataGrid_ItemsSourceChanged(object sender, GridItemsSourceChangedEventArgs e) 

{ 

    //// You can do required process here. 

}  

  

We have prepared a sample based on your requirement and you can download it from the below link.

Hi Rafael, 

  

Thank you for the update. 

  

Your requirement to load a loading indicator while SfDataGrid has been loaded, can be achieved by loading a SfBusyIndicator in the SfDataGrid.GridLoaded event. 

   

Please refer the following code for the same, 

  

 [C#] 

public partial class MainPage : ContentPage 

{ 

    SfBusyIndicator indicator; 

    public MainPage() 

    { 

        InitializeComponent(); 

        indicator = new SfBusyIndicator(); 

                              dataGrid.GridLoaded += DataGrid_GridLoaded;             

    } 

  

               private async void DataGrid_GridLoaded(object sender, GridLoadedEventArgs e) 

               { 

                              //// customize based on the requirement.        

                              indicator.IsBusy = true; 

                              indicator.IsVisible = true; 

                              indicator.AnimationType = AnimationTypes.SlicedCircle; 

                              grid.Children.Add(indicator); 

                              await Task.Delay(2000); 

                              indicator.IsBusy = false; 

                              indicator.IsVisible = false; 

               }              

}
