WPF DataGrid is very slow to render

by

Are you have:

  • Enabled VirtualizingStackPanel.VirtualizationMode for a Grid? if not – try to set.
  • Set VirtualizingStackPanel.IsVirtualizing=”true” for DataGrid
  • Wrapped up a Grid by a StackPanel container? If yes – try to remove.
  • Wrapped up a Grid by an external ScrollViewer control? If yes – try to remove.

One more point,
could you bind whole items collection at once instead of adding each item into the grid.Items collection?
