why DataGridColumn.GetCellContent (DatagridRow) is always null even though DataGridRow is not null?

Question

I am trying to access each cell content when DataGridRow is loaded, but the DataGridColumn.GetCellContent(DataGridRow) is always null though there is data in the DataGridRow for that column. For ex:

    void DataGrid_LoadingRow(object sender,DataGridRowEventArgs e)
    {
      foreach(var colItem in dg.Columns)
      {
        var cell=item.GetCellContent(e.Row as DataGridRow);//Row is not null, cell is null after this execution.       
      }
    }

what could be the reason?

PS: I have disabled Virtualisation of both rows and columns.

Thanks

When DataGrid is about loading row data in a DataGridRow and populating a row, it seems at first it raises the LoadingRow event before appling Data Bindings, etc. Therefore content of its DataGridCells will be null at this point.

It is a thing similar PropertyChanging event (that fires before appling of change). Whereas PropertyChanged event fires after that change occured.

You can use another event for this purpose.
