Mark,

That is a most excellent question. The answer is in the nuance of the app itself. The data for the combos is not available until the page is activated (trust me, I know; many hours looking at the Event Tracking to find a better way). The class is based from someone else's and the best thing I could think to do was check for the property and then don't run the data populating portion if this was the first time through. After the first time, the property is created and then the data portion can be run. You will note that I named it mInitSQL as it originally was in the Init where you would normally expect it.

>I guess that you have created the combos from a combo class, subclassed from the combo control in order to create the version with the cSourceAlias property, so why not just put a mandatory call to mInitSQL in the init or refresh (whichever is appropriate) method of the combo class that you have based these controls on.
