Hi, I need to create RadDataGrid in xamarin forms programmatically. it only creates the header and it's fine. But when I insert new data in ItemSource there has no new row added in UI while ItemSource already updated with new row data. I have tried in several ways and still, there has no progress. Have any other options to add a data row in RadDataGrid? code snippets are attached.

 


  private readonly RadDataGrid dataGrid = new RadDataGrid() { IsEnabled = true, AutoGenerateColumns = false };
  private List<GridModel> dataSource = new List<GridModel>(); 

  public async Task DoSetup()
        {
             Grid outermost = this.GetOutermostGrid();
             this.Content = outermost;
             AddHeaderRow(columsList);
             dataGrid.ItemsSource = dataSource;
             outermost.Children.Add(dataGrid);
             Grid.SetColumn(dataGrid, 0);
        }

private void AddHeaderRow(IEnumerable<string> headers)
        {
            foreach (string s in headers)
            {
                this.dataGrid.Columns.Add(new DataGridTextColumn() { HeaderText = s, SizeMode = DataGridColumnSizeMode.Stretch, Name = s, PropertyName = s });
            }
        }

private void AddNewRow(GridModel model)
        {
            //dataSource.Add(model);
            //dataGrid.ItemsSource = dataSource;
            (dataGrid.ItemsSource as List<GridModel>).Add(model);
        }

HI William, please change `List<GridModel>` to `ObservableCollection<GridModel>`.  When you add items to List at runtime, this will not update any UI elements. Also, when you call `AddNewRow()`, make sure you are not on a background thread.
Thanks for your help. it's working now
