Help - PropertyHasChanged method causes two Tabs to exit field.

andrewrajcoomar posted on Tuesday, January 13, 2009

The PropertyHasChanged method is causing me to have to press Tab twice to exit a textbox. If I replace PropertyHasChanged with MarkDirty, then I have the desired behavior (single Tab to exit field).

I have tried PropertyHasChanged with and without ValidationRules with no effect.

I am using CLSA.Net 2.1.4 and am still having this problem after upgrading from 2.0. I run ProjectTracker without this issue. I have compared by classes with similar projecttrascker classes and cannot see a difference.

Any help would be greatly appreciated (please don't tell me it fixed in 3.5 because it does not compile for .Net 2.0.)

Thanks,

Andrew

This is fixed in 3.5 ;)

Fortunately it is also fixed in 3.0.5, which compiles fine for .NET 2.0 and is the current release for .NET 2.0.

Thanks for the quick reply, Rocky.

I must be missing something because I can't get CSLA 3.05 (Release 3.05-081009) to compile. I am on ASP.Net 2.0 framework. Do not have any WCF components installed.

I tried compiling ProjectTracker as well as the core solution cslavb, no success. I'm not allowed to upgrade .Net framework, right now, or install additional components.

Thanks,

Andrew

Solution: GetValueID must always return a unique value (and not Nulll), during an Insert operation. So basically, I added an ID property of type GUID to my class and my problem was solved.

Originally I was returning my PK property, but that's null during an Insert because it's an identity column in SQL and is set to auto-increment.
