Please help me, Im trying to get the value of Cell[0] from the selected row in a SelectionChangedEvent.
I am only managing to get lots of different Microsoft.Windows
Since you are using the "SelectionChanged", you can use the sender as a Data Grid:
DataGrid dataGrid = sender as DataGrid;
DataRowView rowView = dataGrid.SelectedItem as DataRowView;
string myCellValue = rowView.Row[0].ToString(); /* 1st Column on selected Row */
I tried the answers posted here and were good, but gave me problems when started to hide columns in the DataGrid. This one works for me even when hiding columns. Hope it works for you too.
