Create Heading Header for display with CL_GUI_ALV_GRID

[Former Member]

Hi,

I am currently displaying a report using the class CL_GUI_ALV_GRID (NOT function module REUSE_ALV_GRID_DISPLAY), and I would like to have the selection parameters as a heading (HTML or otherwise) above the grid container. I assume that I can do this using a custom container on the screen, but I am not sure if I should be using the classes CL_GUI_HTML_VIEWER or CL_DD_DOCUMENT or some other class.

If it should be one of the above classes, would it be possible for anyone to post an example of how to get information from an ABAP table into the class object to be displayed?

Thanks in advance!

Eugene

if u want u can handle print_top_of_page event but another simpple way is

in custom container place the selection fields

as text fields

Hi Eugene,

I have created a report with a HTML info, I have used the cl_dd_document class.

If you want a example ..

Hi Frederic,

Seeing as I currently have a problem with the cl_dd_document class, would you be able to email me the example that you mentioned?

vdmeugene-sap@yahoo.com

Thanking you in anticipation

[Former Member]

I have found the reason for my blank HTML container - DO NOT INSTALL Internet Explorer 7 Beta 2 Preview, it causes your SAPGui to leave all the html elements blank.

After removing IE from my system the examples worked, and I am able to do what I want to!

Hi Anjali,

Firstly thanks for the prompt response and the useful code. I implemented it, however, came back with a white area at the top where the documentation is supposed to be.

To ensure that I didnt miss anything, I copied the code exactly and performed a test, and it displayed the ALV section perfectly with the data, but the document in the top section of the splitter was plain white with no content.

Does this code work correctly on your system? If so, is it a SAP GUI problem or a SAP patch problem? I am running GUI 640 Final Release, patch version 4.

[former_member188685]

Hi,

Did you check my code, it works well for me , try it.

even i'm on same version.

Regards

Hi Vijay,

Thank you for coming back, the reason why I didnt use your code is that I do not understand the function and purpose of the function module call 'REUSE_ALV_GRID_COMMENTARY_SET', whereas with the code that Anjali posted there are only method calls, which can all be logically followed.

Your code seems to use a hybrid of SAP function calls and OO methods, and it is not transparent to me what is happening.

time

However, I just pasted your code and the same issue - the grid works perfectly, but the white top section is blank. If you are on the same GUI patch then I can only think that this has to be a system problem. If anyone has any ideas please let me know!
