Thank you for your update.
We analyzed your query and you can achieve your requirement like “scroll to top” by using ScrollInView() method and ScrollLineIndex property. Please find the code snippet as follows :
//Scroll to particular row index
this.syncgrid.ScrollInView(new RowColumnIndex(RowIndex, 0));
//After scrolling, need to set corresponding row index as first visible index in view.
this.syncgrid.GetVisualContainer().ScrollRows.ScrollLineIndex = RowIndex;
We have also prepared the sample based on this and please find the sample under the following location:
