How to convert index to point in .NET MAUI DataGrid (SfDataGrid)?

You can obtain the coordinates when interacting with the .NET MAUI DataGrid by utilizing the SfDataGrid.RowColumnIndexToPoint method. To obtain the coordinates, you need to pass the RowColumnIndex.

These coordinates can be acquired from anywhere during your interactions with the SfDataGrid. Please refer to the code example below.

xaml:

<syncfusion:SfDataGrid  x:Name="datagrid"
                     ItemsSource="{Binding Employees}"
                     AutoGenerateColumnsMode="None"
                     DefaultColumnWidth="155">
 <syncfusion:SfDataGrid.Columns>
     <syncfusion:DataGridTextColumn MappingName="EmployeeID"
                                    HeaderText="Employee ID" />
     <syncfusion:DataGridTextColumn MappingName="Name"
                                    HeaderText="Name" />
     <syncfusion:DataGridTextColumn MappingName="IDNumber"
                                    HeaderText="ID Number" />
 </syncfusion:SfDataGrid.Columns>
 
 <syncfusion:SfDataGrid.Behaviors>
     <behaviors:DataGridBehavior />
 </syncfusion:SfDataGrid.Behaviors>
 
</syncfusion:SfDataGrid>

Behavior:

public class DataGridBehavior : Behavior<SfDataGrid>
{
  protected override void OnAttachedTo(SfDataGrid dataGrid)
  {
      dataGrid.CellTapped += SfDataGrid_CellTapped;
      base.OnAttachedTo(dataGrid);
  }

  protected override void OnDetachingFrom(SfDataGrid dataGrid)
  {
      dataGrid.CellTapped -= SfDataGrid_CellTapped;
      base.OnDetachingFrom(dataGrid);
  }

  private void SfDataGrid_CellTapped(object? sender, DataGridCellTappedEventArgs e)
  {
      SfDataGrid grid = (SfDataGrid)sender;
      Point point = grid.RowColumnIndexToPoint(e.RowColumnIndex);
      Debug.WriteLine(point.X + " " + point.Y);
  }
}
