Answer 1

If you are populating the DataGrid by using:

dataGrid.Items.Add(someObject);

Then you should be able to use:

dataGrid.Items.Clear(); 

To remove all the rows.

If you are binding to the ItemsSource like:

dataGrid.ItemsSource = someCollection;

Then you should be able to set the ItemsSource to null and it will remove all the rows.

EDIT:

Don't forget to refresh it:

dataGrid.Items.Refresh();
