ALV in Webdynpro ABAP

Hi,
When ALV is in edit mode, there are four default actions (buttons) in the toolbar of ALV - 'Check', 'Append row', 'Insert row' and 'Delete row'. I just want to know that when 'Append row' is clicked, Which event is triggered.
I need this to set some default values in the cells of newly inserted row.
Regards,
Gaurav

Hierarchical sequential display in ALV for webdynpro ABAP

Hello,
I am doing an ALV report WebDynpro for abap. I have a situation where I have to display Open Items and all the partial payments in the ALV report. In short. In summary, I have to display a Hierarchical Table of data which two different structures of data, but linked and displayed together.
The only information I have to go about this is [Table as Hierarchy|http://help.sap.com/saphelp_nw2004s/helpdata/EN/3e/904b2624534e0db707c7314a5e1e9d/frameset.htm] in SAP Help.
If you have any pointers for programming a Hierarchical Sequential report in Webdynpro alv that would be great. Any classes, methods etc I can use or , how I can do bindings to the context etc...
Thank you for all your help.

Drop down in ALV for Webdynpro ABAP

Hi Experts,
I was trying to implement one Web dynpro ABAP application that will show one ALV and ALV will content one dropdown so that user can select data from the drop down. Addtion to that, my dropdown should have data based on another column of ALV.
I have followed one article which is available in Net.
At the end of development, ALV is displayed with dropdown. Also dropdown has data binded. However, no data is visible in dropdown.
I have created one context node having four dictionary element and one elemt for dispplaying the dropdown.
In the DoInit method of view, i have written below code:

I am still finding the answer why data in drop down is not visible. However, I can select by clicking dropdown and blank elements (since data is not visible) can be selected.

Hey
i am using the same code except i have just modified little bit the select statement to restrict the number of entries.
and also besides writing the code in wddoinit i have added the compenent usage of alv component and added the node
having the structure ckst and after that deleting the dictionary reference to add the attribute valueset in both places
component controller and view controller and mapped them and mapped the data node of interface controller of comp
usage to this node in comp contrlr.
and adding the view container and embeding table view of alv comp there.
that's it
and here is the code which is almost same as yours except small change in select statement.

Interactive ALV in webdynpro ABAP

I have a requirement where in, i have to show a report in ALV and on lead selection from ALV list i need to show another screen with some UI elements.Since i use view container elemnt it doesnt have required properties.
Please help me to find out existing methods which can help me making the ALV list interactive to show another screen.
I searched in the forum but didnt get the required solution.
Thanks in advance.

Naveen,
The basic Concept of using the ViewContainerElement is to bring the View of another component into the calling component. That means, the actions and methods for the table or any UI Element will still exist inside the View of the Called Component, the ViewContainerElement is just a Place Holder for this Called View.
Let us consider an Example:
v_view1 --> Calling Component
v_view2 --> Called Component
v_view1 will have the ViewContainerElement (V_CONT) binded with the inbound plug of v_view2 window.
v_view2 will have all the actions, methods, events to handle and manipulate the data.
So, anytime, there is a lead selection of the data, the events from v_view2 will be active to handle the leads.
To understand this, you need to debugg the v_view2 methods, anything which you have already created.
Please let me know, whether I've addressed your query properly.
Regards,
-Syed.

Webdynpro ABAP -- ALV Layout setting

Dear all,
In my development with ALV in Webdynpro ABAP, I want to save the ALV layout via Setting. but it seems that the layout only can be saved as user-specific, is it any possible to use it as the gobal one?
Please kindly provide me some hints. Thanks in Advance.
Best Regards,

Hi,
Yes you can make it global in administrative level.
1.In SE80 ,Double click on the name of your Web Dynpro Application .
2.Select Web Dynpro Application Menu .
3.Select Test->-> Execute in Administrative Mode from the menu.
Your application opens in administrative mode .
Go to the ALV settings make the changes and save it as some variant.
This layout will be default and global to all the users.

HI,
If you want to change the Source (Design time) then you can do that via the alv configuration.

Check the interface if_salv_wd_std_functions. It contains methods which are used to hide the standard ALV toolbar buttons.

Hi,
This may help you to define your own column text in the ALV Table of webdynpro.
see the below code.
Here 'STATUS_ICON' is the column of the the output display of the ALV Table of webdynpro.
"change the label of the report.

Looking forward your valuable comments.

Hi Venkat,
We can achieve the HIERARCHY through the following code.In this case I have used CARRID as the drill down column.
data lo_cmp_usage type ref to if_wd_component_usage.
lo_cmp_usage =   wd_this->wd_cpuse_flight_tree( ).
if lo_cmp_usage->has_active_component( ) is initial.
   lo_cmp_usage->create_component( ).
endif.
DATA lo_INTERFACECONTROLLER TYPE REF TO IWCI_SALV_WD_TABLE .
lo_INTERFACECONTROLLER =   wd_this->wd_cpifc_flight_tree( ).
   DATA lv_value TYPE ref to cl_salv_wd_config_table.
   lv_value = lo_interfacecontroller->get_model(
lv_value->IF_SALV_WD_TABLE_SETTINGS~SET_DISPLAY_TYPE( IF_SALV_WD_C_TABLE_SETTINGS=>DISPLAY_TYPE_HIERARCHY ).
"Enable HIERARCHY structure
data lr_col type ref to CL_SALV_WD_COLUMN.
lr_col = lv_value->IF_SALV_WD_COLUMN_SETTINGS~GET_COLUMN( 'CARRID' )." Enable HIERARCHY for the col. specified
lr_col->IF_SALV_WD_COLUMN_HIERARCHY~SET_HIERARCHY_COLUMN( ABAP_TRUE ).
