If you re using the MVVM pattern you can bind a SelectedRecord property of your VM with SelectedItem of the DataGrid  this way you always have the SelectedValue in you VM  Otherwise you should use the SelectedIndex property of the DataGrid

You can use the SelectedItem property to get the currently selected object  which you can then cast into the correct type  For instance  if your DataGrid is bound to a collection of Customer objects you could do this   Customer customer    Customer myDataGrid SelectedItem    Alternatively you can bind SelectedItem to your source class or ViewModel    lt Grid DataContext  MyViewModel  gt       lt DataGrid ItemsSource   Binding Path Customers                 SelectedItem   Binding Path SelectedCustomer  Mode TwoWay    gt   lt  Grid gt

Just discovered this one after i tried Fara s answer but it didn t work on my project  Just drag the column from the Data Sources window  and drop to the Label or TextBox

There are a lot of answers here that probably work in a specific context  but I was simply trying to get the text value of the first cell in a selected row   While the accepted answer here was the closest for me  it still required creating a type and casting the row into that type   I was looking for a simpler solution  and this is what I came up with   MessageBox Show   DataRowView DataGrid SelectedItem  Row 0  ToString      This gives me the first column in the selected row   Hopefully this helps someone else
