What are the differences between DropDownList and DropDownValidate in a column's Style property in the UltraWinGrid? Does either one offer any performance or functionality advantages over the other?
DropDownList prevents the user from typing into the cell. They can only choose items from the list.
DropDownValidate allows the user to type into the cell, but it will raise an error if the text they end up with doesn't match an item on the list.
DropDownList is much more commonly used and DropDownValidate is useful in more unusual situations.
I don't know if there is any significant performance difference.
