title: UI Design Query : Many to many relationships for data entry UI
body: <p>I am designing a Data Entry UI for a WPF application and have a scenario where I need to enter a many-many relationship.</p>
  
  <p>Object A is Parent object. A has an observable collection of type Object B.</p>
  
  <p>Object B has two text fields and an observable collection of Object C which has four text fields. </p>
  
  <p>I need to create a UI which will allow an efficient addition of B and C.</p>
  
  <p>I have created a Nested Tab Control where the outer tab control has object B and it has an inner tab control which can accommodate many object C in it.</p>
  
  <p>However this UI looks ugly and non intuitive. Any suggestions on what would be a better way? </p>
