title: How to connection two tables(master-detail) in devexpress treelist?
body: <p>I have two tables: Department and User. The department is a tree-style structure with the field PDeptID and DeptID (its key), so I put it into the XtraTreeList component.</p>
  
  <p>The User table linked to Department with DeptAndUser table, and there are DeptID,UserId fields within it.</p>
  
  <p>I want to setup the TreeList with Department and when I click the department ,the right grid control will display all the users in this department.</p>
  
  <p>How do I accomplish this idea?</p>
