Lets say I have a custom property that is a text box that can be a range of
numbers.

How would i validate this and raise an error label if the validation fails???

Thanks for your help!

The validation should be placed in the ApplyChanges() method, where you
can compare the value currently in your Toolparts textbox with the
accepted range.

If you determine that it is within the accepted range, you assign its
value to the Webparts custom property, if not you could make visible an
otherwise hidden label with your error message.

This should ensure that you never get invalid data persisted to your
custom property.

Hope this helps.
