Any one could give the difference between webtop component and wdk component?
Thanks in advance.
Webtop layer sits on top of the WDK layer, so a lot of Webtop components extend WDK components. If you are using Webtop, you are more than likely to extend Webtop component. You would use WDK components if you were building your own custom WDK app.
wdk contains basic controls, for example text, dateinput, radio button controls
webcomponent contains useable features, like, import, new document, ....
webtop, brings it all together, into a useable application
custom, is the for your changes ( but myself I perfer to add my changes into a seperate layer (or two if I want to resuse code across clients/applications )
Other apps add an extra layer, for example the admin client has a layer "da"
