Currently, when EditType = etRange, then multiple range characters are allowed: I have found out: semicolon, comma, hyphen. This vagueness can lead to confusion in the user. So please implement a new property "RangeCharacter" (a single character). It could be set to "x" or "*" (multiplication sign) to edit the two dimensions of a rectangle. Or it could be "/" or ":" to edit a numerical ratio or a value pair of hours:minutes, etc. You can see that a property "RangeCharacter" would add a lot of flexibility to the control. Of course, the range-character would be fixed in the control and could not be edited. Only the numeric values on both sides of the range character can be edited.
This feature was implemented.
