  Hi
  
  I have an issue in WPF flexgrid SelectionChanged event.
  
  e.cellrange gives me row =1 but the selectedindex is 0.

  What could be the reason?

  Hi David,

  We created a sample project to test this scenario using the latest version of FlexGrid (4.6.20251.882). In our testing, FlexGrid.SelectedIndex, FlexGrid.Selection.TopRow and e.CellRange.Row properties all return the correct and consistent index in the SelectionChanged event.

  We have attached the sample project for your reference. If you are encountering the issue with a different implementation or version, please update the attached project to reproduce the problem. This will help us investigate the issue further and provide better assistance.
