The type to convert is actually a in-house Color struct. Converted from a string, the format has to be 'red, green, propertygrid error handling blue, alpha'. Everything works fine if the string provided to the TypeConverter is valid. However, if the user provides an invalid string format, the TypeConverter has to react in some way to let the UI know the data provided by the user is invalid. What I did in this case is throw an Exception, thinking the property grid would catch it to display the exception message to the user. For types provided in .NET (for example System.Drawing.Point), entering invalid data pops up a dialog box explaining why the format is invalid. I am trying to get the same behavior and I can't figure out how. Disassembling System.Drawing.PointConverter shows an invalid input string will return an Argument Exception. If I do the same in my TypeConverter, I get an unhandled exception and the application terminates. Bad. How can I get that popup to show my error message so the user can correct his mistake instead of that crash? -Sylvain Reply With Quote September 6th, 2008,11:57 AM #2 sylvainboisse@hotmail.com View Profile View Forum Posts Junior Member Join Date Aug 2006 Posts 20 Re: PropertyGrid vs TypeConverter with invalid data Anyone?

The problem is that CXTPPropertyGridItem::OnValidateEdit() is usually called on CXTPPropertyGridInplaceEdit::OnEnKillfocus(), which can be invoked by a number of various actions (messages, commands, ...), and I do not know how to interrupt/cancel such actions after displaying an error message. For example, I have two MDI child-frames, using the same property grid. If I enter a wrong value into the grid and click on the second child frame, the program displays an error message correctly but, after that, it continues and activates the second frame, which is bad. The frame-activation should be canceled so that the user could fix the incorrect value in the grid. I would be able to solve it for this action type (MDI frame activation) but it does not make any sense because there are hundreds of other actions causing the same problem. I believe that there should be a standard mechanism in your Property Grid, solving this problem on a general level. Please let me know if you know a solution or if there is a XTP-example in which I could find a solution. Thank youM.
