Hi,

what would the best way to implement the functionality of setting a minimum and maximum value for a numeric or double property grid item? Any input outside the min/max constraints shall not be accepted.
Actually the item shall behave like an item with a slider or a spin button (if the user types in a value outside the slider/spin range, it will be rejected) but I dont want to have such a button.

The solution I'm thinking of is to derive on of the XTPPropertyGridInplaceEdit or the XTPGridItemNumber/Double classes.

Is there another (maybe smarter) way?

Thanks in advance
Stefan

Hello,

You can catch XTP_PGN_ITEMVALUE_CHANGED message and update value, or XTP_PGN_EDIT_CHANGED and change value while user edit it.
