Dears,
I'm working on the project based on the Syncfusion and I have the following issue to solve.
We have the SfDataGrid with some data and it is easily scrolled (obviously).
I'd like to detect the index of the row which is currently displayed on the top of the DataGrid.
Which method should I use?

Best regards,
Agata

Hi Agata, 

Thank you for using Syncfusion Products. 

We have analyzed your query to get the first visible row index in view. Your requirement can be achieved by using the VisibleLineInfoCollection as like below code snippet 

private void Button_Click(object sender, RoutedEventArgs e) 
        { 
            var visibleLines = this.sfdatagrid.GetVisualContainer().ScrollRows.GetVisibleLines(); 
            var firstVisibleRow = visibleLines.FirstOrDefault(line => line.Region == ScrollAxisRegion.Body); 
            var firstVisibleRowIndex = firstVisibleRow.LineIndex; 
            MessageBox.Show(firstVisibleRowIndex.ToString()); 
        } 

Please find sample for the same from the below link

Please let us know, if you need any further assistance on this. 

Regards, 
Shobika.
