This control is not ready for practical use. It has almost no usable server methods. It doesn't even have a server SelectedIndexChanged event? How am I supposed to get SQL data based on when the user makes a change? It has no ItemDataBound...how am I supposed to add attributes for data I don't want to show?
This is like building a car and putting on a nice fresh coat of paint, but not including the engine or the tires. I was excited to finally use a true multicolumn combo box in our produtcts, but I can't use this control in it's current state. I am super dissapointed.
