I've just released a new version of my DataPanel on GotDotNet. Anyone who have ever made a ASP.NET dataentry web form with a lot of textboxes for editing data in a lot of columns know it's a tiresome task. You have to set all the Text properties on load...

Tables != Classes

More on Typed DataSets

Just noticed that if you should happen to use: codegen : nullValue ="_empty" on something else than a string the MSDataSetGenerator will fail to generate any code file at all. Usually when errors are detected in the XSD both the xsx and cs file is generated...

Remoting Typed Datasets - the tryouts
16 May 03 04:58 PM | madsn | with no comments

Andres stepped up quickly with some hints to my previous blogentry . I tried out the ADO.NET Powertoys which contained several features. Because it was poorly documented, and I just needed one of the features, I think I'll wait for a later release. I...
