title: How Do I refresh window in wpf?
body: <p>I have a small project I am working on which is a window with 4 WPF tabs on it.</p>
  
  <p>The first tab is where I do most of the work, but occasionally I need to move back to other tabs. One of these tabs has a DataGrid that is bound to a list that is affected by the main tab I stay on.</p>
  
  <p>When I update something on the first tab, I need it to cause a refresh on the data in the Datagrid(usually just to update a value).</p>
  
  <p>The only way it has been working is if I click on the header myself.</p>
  
  <p>How can I do this in code?</p>
  
  <p>Thanks</p>
