The application generator automatically configures memo (long text) fields as multi-line text boxes. The column Categories.Description from the Northwind sample is an example of a memo field. 
  
  The property Rows of the Categories.Description data field has a default value of “5”. Changing the number of rows of the data field to “1” will convert the field into a single-line text box.
  Start the Project Designer. In the Project Explorer, switch to the Controllers tab. Double-click on Categories / Fields / Description field node.
  
  At the top of the Designer window, switch to the Data Fields tab. Change all data fields as shown next:
              | Property | New Value | 
             | Rows | 1 | 
   

  Save all changes, and click Browse on the toolbar. 
  When the web app opens in your default web browser, navigate to the Categories page and edit a record. The Description field is now rendered as a single-line text box.
  
  The Rows property of standard string fields is blank. Changing it to any value greater than “1” will convert the data field into a multi-line text box.
