How to get the last data row index

Question

I am migrating a UWP application to WinUI and I need to convert the existing code for a UWP SfDataGrid to the equivalent syntax for the WinUI

SfDataGrid.My current implementation includes a call to get the index of the last data row, so that it can be scrolled into view:myGrid .ScrollInView(new RowColumnIndex(myGrid.GetLastDataRowIndex(), 0));﻿﻿Unfortunately, I don't see any

GetLastDataRowIndex()  method on the WinUI grid.Can you please tell me how to achieve this? Thanks.

Hi Tim Coulter,We are regret to
inform you that the DataGrid.GetLastDataRowIndex() is not available in the WinUi platform.
However you can get the index of last data row using the below code snippet.

public int
  GetLastDataRowIndex(SfDataGrid DataGrid)
  {
      if (DataGrid.View.Records.Count == 0)
          return -1;
      int count = 0;
   
      VisualContainer visualContainer =
  (VisualContainer)DataGrid.GetType().GetProperty("VisualContainer",
  System.Reflection.BindingFlags.NonPublic |
  System.Reflection.BindingFlags.Instance).GetValue(DataGrid);
   
      int index = visualContainer.RowCount -
  (DataGrid.GetTableSummaryCount(TableSummaryRowPosition.Bottom) + 1);
      if (DataGrid.AddNewRowPosition == AddNewRowPosition.Bottom)
          index -=
  1;
      if (DataGrid.FilterRowPosition == FilterRowPosition.Bottom)
          index -=
  1;
      for (int start = index; start
  >= 0; start--)
      {
          if
  (!visualContainer.RowHeights.GetHidden(start, out count))
             
  return start;
      }
   
      return index;
  }
