How to get selectedItem value from a WPF DataGrid

For the DataGrid you can capture the SelectionChanged event.


In your XAML you would type SelectionChanged= and then press tab to allow it to create a method for you in the C# code.


Once you've done that you should go to the code files that accompanies your XAML file and find the event that was created.


For me it was:


SelectionChangedEvent


In this event I would add logic that would capture the msgId . Here is an example:



 private void SelectionChangedEvent(object sender, SelectionChangedEventArgs e)

        {

             //e.AddedItems contains the selected data

             System.Collections.IList selectedRow = e.AddedItems;

       //Logic to get the msgId from the IList
       // - in my example I am binding to a DataTable
       // - also notice that selectedRow[0] because I am
       // - allowing only 1 row selection at a time.


             if (selectedRow.Count > 0)      

                 msgId = ((AwareAlertUser)selectedRow[0]).MsgID.ToString();                   

        }
