Here is a method to populate a dropdownlistbox control with values from a sql statement.\u00a0 Since it is based on a datastore you can easily apply filters, sorts, etc. prior to populating the dropdownlistbox with values.\u00a0 The code assumes the first column in the SQL is going to be used to populate the dropdownlistbox .<\/p>\n
When you call the function you send the dropdownlistbox and the sql string.<\/p>\n
