title: Adding a LookupComboBox to a CXGrid cell
body: <p>Apart from getting LookupComboBox on a cell via the below given method is there any other way?
  <code>
  -Select a column
  -From Properties select LookupComboBox
  -fill out the required data suchas listsource, listfieldnames etc</code></p>
  
  <p>The reason behind for looking an alternative solution is i am getting data in CXGrid by joining multiple tables and thus when i use the above method then i run into errors</p>
  
  <p>i am looking for a example where i am able to LookupComboBox on a cell of CXGrid , Help!!</p>
  
  <p><strong><code>Updated Question</code></strong></p>
  
  <p>With the below suggestions i have tried to re-frame my question i think this should make sense now</p>
  
  <p>I have a table Employee and Department</p>
  
  <p><code>Employee
  EmpID, EmpName, DepID</code></p>
  
  <p><code>Department
  DepID, DepartmentName</code></p>
  
  <p>So in the cxGrid What I want is</p>
  
  <p><code>EmpID, EmpName, DepartmentName</code></p>
  
  <p>Thus the query which was given to <strong>GridDataset</strong> to fetch the data was </p>
  
  <p><code>SELECT EmpID, EmpName, DepartmentName FROM Employee
  INNER JOIN Department ON Department.DepID =  Employee.DepID</code></p>
  
  <p>Next step is DepartmentName field in CXGrid should be edittable via a lookupcombobox
  Thus 
  -Select a column(DepartmentName)
  -From Properties select LookupComboBox
  -fill out the required data suchas listsource, listfieldnames etc
  <strong>Here the is ListSource is another dataset which is refering to Department with KeyFieldName as DepID</strong></p>
  
  <p>With all this setting when i try to view the data in cxgrid by doing GridDataset.open then i get the following error message
  <strong>"Could not convert variant of type (UnicodeString) into type (Boolean)"</strong></p>
