WPF DataGrid flickering issue
问题 In WPF, I have a DataGrid bound to a DataView in the ViewModel class. It is a touch panel embedded project, so every time I touch and slide my fingers on the panel it keeps sending me values and saves those values to the DataTable and assigns it to the bound DataView in a way where it can show only 5 or 10 rows (predefined) as the data gets updated. Every time I get a new row I delete the last until the total DataTable row count is 5/10. The issue here is that it is taking longer than usual
