How to replace listbox table fields in webdynpro application

[Aditya]

Hi all,

I am not sure whether I am asking a small querie or a markable query, as I am new to Webdynpro module.

There is a listbox which is getting dispalyed with the help of database table.

I need to change the list box data with other internal table by replacing database table details.

How can I change it. please tel me in a detailed manner with the help of screenshots.

Please tell me on urgent basis.

Hi,

You can achieve your requirement as below

• Let us say, your list box ui element's datasource is bound to a context node MY_LIST as below

         

• Identify the location where the values of node MY_LIST is getting populated and there you can have your own set of data and bind it to context node MY_LIST

            lo_node->bind_table( new_items = lt_new_list ).

Here, you only need to do is bind the new set of values to context node which is bound to LIST BOX.

Hope this helps you.

Regards,

Rama

Hi,

Yours is not an ITEMLISTBOX, its a DROPDOWNLIST, and its done by binding the context node DROP_DDI and attribute ZZMODULE.

Now, you need to bind the NEW values to context node DROP_DDI, so that it reflects in DropDownByIndex element.

Check for methods WDDOINIT( ) or some other methods, where data of drop down list is getting populated.

Hope this helps you.

Helo,

Create a new table UI element, and make binding to the node which is already bound to listbox. data which is displayed in ListBox, that will be displayed in tabular format. Ensure to keep the required columns only while creating Table UI element.

Hi Chengalarayulu,

I had tried to create new UI element. But only the option 'Display UI element' is enabled from the rest.

If I click on 'Display UI' element, I was getting 'No values found' as an information message.
