How to Drag and drop Between ALVs

[Former Member]

Hello Experts,

Thanks.

Drag and Drop with ALV is not possible until NetWeaver 7.02. If you are on NetWeaver 7.01 you can do drag and drop with the regular table UI element, but not with the ALV.

Hi Thomas,

In case of simple table how can we do that.

You can read about Drag and Drop in WDA 7.01 in the online help:

Hi Thomas ,

Im working on using a Drag & Drop in a Web Dynpro ALV Tree. I have declared my target alv as a Drop Source , but now im unable to figure out how to trigger an event on the drop to change the contents of my target table.

Warm regards,

Newton.

In NetWeaver 7.01 the table has onDrop events, but these events are not exposed via the ALV. It is not until NetWeaver 7.02 that drag and drop is extended to the ALV.

Hi Thomas ,

Thanks for your reply.

Im sorry , i forgot to mention that im working n NetWeaver 7.02.

Im not able to figure out where to implement the handler for the ON_DROP event in the ALV.

Is there no such event handler in the ALV Configuration Model ?

How do i code the event handler implementation for a drop event on my ALV ?

Thanks.

Newton.

Here is the online help for ALV Drag and Drop in 7.02:

ON_DROP is a standard event exposed by the ALV like any other event. If you don't see it in the list, then you probably aren't on a 7.02 system.

Go to your Web Dynpro component that is hosting the ALV component. Go to one of the controllers - probably the component controller. On the properties tab Used Component/Controller reference for the ALV component. Now go to the methods tab. Create a method of type Event Handler. Choose the value help on the event column and all events of all referenced Components/Controllers will be displayed (this is the screen I shared before). Chose the event that you want to associate with your event handler method.
