title: How to know the one selected row in the tabs containing the datagridview
body: <p>I have a project with a form with 3 tabs, each contains 1 datagridview. I disabled multiselect and can only select a row.</p>
  
  <p>I need to Add new data rows or Modify rows of datas from these three datagrids, so I have a MenuStrip on top of the window with a menu with a "Add", "Modify" and "Delete Selected Row" options.</p>
  
  <p>How do I know which row is currently being selected in the current selected tab containing the datagrid which contains that row? Because there are 3 tabs containing 3 datagrids. I don't want to get the output saying there are 3 datagridviews selected with whatever row was selecting. I want the one row on my screen.</p>
  
  <p>Please ask me if my question isn't clear enough.</p>
