How to iterate through Datagrid and create the data row in wpf?

Question

I have to convert windows form control to WPF. I want to know how to iterate through Datagrid in WPF.

 For Each dr As DataGridViewRow In dtg.Rows
 If dr.Cells("Name").Value.ToString.Trim <> String.Empty Then
 row = dt.NewRow 'Create new row
 For cn As Integer = 0 To TotalDatagridviewColumns
 row.Item(cn) = IfNullObj(dr.Cells(cn).Value) ' This Will handle error datagridviewcell on NULL Values
 Next
 dt.Rows.Add(row)
 End If
 Next

I want the above mentioned to work in WPF DataGrid.
