title: How to change the value of a Text Box depending on the currently selected row within a Data Grid?
body: <p>Hi I'm hoping someone can help,</p>
  
  <p>I have a Data Grid that has X amount of rows and I have a Text Box at the bottom of my form called 'Notes', I want the user to be able to select a row then enter a note within the Text Box and store this so when the user selects a different row the Text Box will be blank available for notes to be added for the new row. Then if the user selects a row that they have added notes to the Text Box will contain those notes.</p>
  
  <p>I hope that makes sense, any ideas on how to approach this would be really appreciated.</p>
  
  <p>Thanks,</p>
