title: Converting text box to dropdown in Dynamic Data
body: <p>I have a Dynamic Data app that uses two tables. For one of the tables, there is a column that I would like to set based on a column in the other table, using a dropdown populated with the values from this other table. Currently this column is generated on the page as a text box entry. However, Dynamic Data doesn't provide a dropdown item to provide a UIHint for this. I tried modifying the Enumeration field control to do this, but couldn't seem to get it to work.</p>
  
  <p>I should specify that this is for adding a new entry from the Insert page for one of the tables. I'd like to have one of the items on the insert page to be set based on a value from a column in the other table, using a dropdown of values populated from the column in that other table.</p>
