Hi
Webdynpro is not a complete MVC pattern stuff , but it has also a controller and views.Views are to be completely out of the business logic but webdynpro allows us to put business logic inside the views.
Controller and Windows acts as the Controller in the MVC pattern
Thanks

How to create calendar in web dynpro abap

Hi ,
how to create calendra in web dynpro abap.
Thanks in advance.
Regards, Chetan

hi,
For calender control, there is Date Navigator under "complex tab". You can just click and drag it and provide calender control.
One more easy way is to create a input field. In the context, create a node and attribute of type "D"(which means DATE). And bind the context to your input field under "values" in property window. While running the program, you will see an calender attached to lt on the input field.

Hey how to upload ABAP web dynpro's in the EP server?

Hi Folks,
please let me know how to deploy the created ABAP Web Dynpro's into the Enterprise Portal.
thanks ,
NKumar

Hi NKumar,
You can put your web dynpro application on portal.
We can publish web dynpro application on portal through "iviews".
Portal eventing is necessary during a scenario where u have to communicate to another portal iview.say in portal u have your WDA app in one iview and another WDA or BSP app in another iview
But for WDA app,navigation inside its views you would not need portal eventing.
This Will help you,

How Can I convert or include a Transaction to ABAP web dynpro

Hey,
Im new to web dynpro, and I have followed sap web dynpro tutorials step by step but I couldnt find a way to create an interface the same way I create screens. Can anyone tell me how do I design an interface in web dynpro or is there a way to convert my transaction to an ABAP web dynpro application?
Thanks.

No there is no way to convert your gui based screens to web dynpro, you have to design them in web dynpro. And the design of WD is not like normal screen painter(SE51).
What I would suggest you is first go thru some basic tutorials, then you will get the idea of UI elements which are used in WD.
Have a look on this link

Creating 'Z' views for Standard ABAP Web dynpro Application

Hi Experts,
I am totaly new to ABAP web dynpro objects.
In our project there were some client requirements which required us to change the properties of the Views related to the Webdynpro. The Client now has said that he needs to apply some enhancement pathces on his system. Due to this, the changes made to the Views i.e all the changes done in standard code are lost.
The client now wants a long term solution where all the changes need to be done in 'Z' implimentataion so that changes are not lost every time the pathces are applied.
Is it possible to create an entire new 'Z' Views for the standard Webdynpro instead of standrad ones?
If Yes how does one link them to the Webdynpro application ?

Hi
Have a look at following article about enhancing webdynpro applications.
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/700317da-bd79-2c10-368e-8f18bf5d8b81?quicklink=index&overridelayout=true

Abap web dynpro and portal events

First off, a little introduction: My name is Martin Kroppen, I am an Abap developer for SAP Netherlands, and I am currently involved in a project for hospitals to built a portal. For this, I have created 2 Abap web-dynpros, and then impemented the views as iviews in an EP. What I want to achieve is that the input view triggers the display view on a second page, and the data is shown for the values in the input view (all in the same browser window).
I am using the portal integration manager for this, with the method for relative navigation.
The navigation is working fine, only problem is that I don't know how to handle the business parameters that I send over.
My questions are:
1. is this the correct way for navigating between abap webdynpro iviews in the portal?
2. what is the correct way to read the business parameters into my context of the second Abap WD application?
I tried the solution that is described below, I could not get it to work correctly.
If you define BUSINESS_PARAMETERS as application parameters in your Web
Dynpro application and the parameter names start with ″APP″, they will
automatically be forwarded to the startup plugs of the Web Dynpro application
provided they are marked as startup parameters. In this case, keep in mind that
the iView/page used as the navigation target must be assigned to the user role.
If it is not, navigation cannot be triggered.
Hope someone can help me
Regards
Martin Kroppen

thanks in advance.

Hi Ramu,
Yes, ABAP Web dynpro is a Netweaver product. It cums with mySAP suite.
This is the hot technology in the market and if you are not a JAVA guy then you must go with ABAP Web dynpro.
Basically with the help of ABAP Web dynpro we develope custom products for the client. this is UI based technology and one of best option for "ABAPers" .
For Web dynpro ABAP you will require SAP ECC 6.0 onwards and WAS 7.0
is a must. It has very good future propspects as this is best UI technology.
In web dynpro ABAP we follow MVC(Model View Controller) architecture.
In this object oriented ABAP is used to provide background functionality. Here, your ABAP skills can be utilized to the fullest. Programming in web dynpro ABAP is different than conventional ABAP programming. Here we strictly follow MVC architecture in terms of controller interface. Also there are many wizards available so that we can directly pick the code from wizards.
e.g We can call BAPI through a service call in web dynpro application. Thus automatically backgroud code for BAPI execution will be generated.
To start with Web dynpro ABAP you can try following tutorial:
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/a282c952-0801-0010-1eb5-87953e036712
You can start with tutorials and all. There are around six tutorials in SDN library.

Anything new about abap web dynpro?

Hi out there!
(First, I'm sorry: I know, this question is related to Web AS General-forum, but I think, I wouldn't get any answer there.)
Is there anything new about abap web dynpro? Just saying wait for nw05? No nice preview/minisap/promotion? Perhaps documents in service.sap.com? I read, it is used in some ramp-ups for ecc 05 (neither knowing, what it is). Is there nothing to say about? Is it drag&drop deployment like java webdynpro or more coding like mvc-"Basteln" in abap/bsp? Are BSP-Extensions used there? Something exiting new?
That are enougth questions for starting.

Brian McKellar is gonna lock this thread:-)
Anyway you can find some info about WebDynpro for ABAP in the Teched 2003 presentations in SDN and there is a quite detailed overview with examples in the Online help.
For the linux version of NW'04 MiniSAP the non-supported version ABAP Dynpro is available....anyway for MiniSAP you don't get support;-)
Peter
Ps: "Something exiting new?"
The whole thing is something really exiting!!!

Hi
First try a very simple application with nothing in it just one text saying Hello World
Run it and see what happens.
Also check if your url uses FQDN name. something like https:
company.name.co:50000\.......
If you do not use the FQDN it will always show a script error on the bottom and some functions will not work e.g
dropdowns.
regards
Yuval.
