ALV in Webdynpro

[Former Member]

Hi,

I have a problem in ALV when used in webdynpro. I am reusing a component salv_wd_table. It also provides default buttons such as insert row, delete row. When i click on insert row it does inserts a new row in ALV, but i also wanted an automatic number to be generated along with it for a particular column. I dont know where to insert the autogeneration-code ie to which method or event handler to achieve this. Can anyone give a solution to this.

Points wud be rewarded graciously.

Thank you,

Jithesh

Hi Jithesh.

You can register for some events of the ALV component.

ON_STD_FUNCTION_AFTE After executing a standard ALV function

ON_STD_FUNCTION_BEFO Before executing a standard ALV function

So you have to create an event handler method in the controller of the component

that has the component usage to the ALV component. There you can select the

event you want to register for.

The ALV component then passes an object of type

IF_SALV_WD_TABLE_STD_FUNCTION to the event handler method. Then you can

check out what standard method was processed (Insert, Delete, ...) and add the

auto number to the new added row.

I did not test this so far, but I guess thats the way it works.

Hope this helps a bit.
