Setting the user defined data for a dialog column control type
These are the guidelines when defining
			user-defined data:
 
	 - Make use of 1,012 characters to define a parameter.
 - The parameters string must be in JSON format.
 - Commas and quotes are used for parsing the parameters.
 - The entire parameter must start and end with curly brackets.
 
The default field parameters are already configured. This procedure is optional.
