Message Area Visible Area increasing

[Former Member]

Hi All,

I'm developing a web dynpro component and in this component i'm using "Message Area" UI element. I want to display multiple

messages in this message area. Problem I'm facing is when I'm displaying like 10 or more message the size of message area

is increasing and I dont want this to happen. I want message area to display 3 or 4 messages and then have a scroll bar.

I'm getting scroll bar but message area is increasing with the number of messages (displaying all 10 or 20 messages at a time).

I tried to setting "Max Visible Lines" property of message to '3' & '1' & '2' nothing worked, also tried changing layout to of the view to matrix, as i will get Height property but no luck.

Now system is displaying message as below.

but i want to display as following.

Above screen shot is from standard web dynpro application "WDR_TEST_MSG_AREA". I maintained properties of message area in my application similar to the message area of standard application, but didn't got results.

Thanks in Advance.

Hi,

You could create an Transparent container and set the height( in px) and scrolling mode to auto. Then place your message area inside it.

hope this helps,

Hi Kiran,

Thanks for your reply. I created Transparent container and set height and scroll mode. Now I'm able to set the height of the message area, but new problem came up. Now I'm having double vertical scroll bars, 1 for Transparent container and other for Message area. I tried a lot but couldn't get rid of scroll bar of message area. I couldn't find a way to disable scroll bar of message area.

Thanks in advance.

Hi MRA,

To remove scroll bar of message area, you need to set the Max visible messages to always more than the no. of visible messages.

proceed as below

• Create an attribute MAX_MSG_VISIBLE of type I, just under CONTEXT
• Bind the attribute to property "MaxVisibleMessages"
• Now, write the below code in wddomodifyview( ) method

     METHOD WDDOMODIFYVIEW.

   data lo_api_controller     type ref to if_wd_controller.
   data lo_message_manager    type ref to if_wd_message_manager.
   data lt_messages           type if_wd_message_manager=>TY_T_MESSAGES.
   data lv_msgs_count         TYPE i.


   lo_api_controller ?= wd_This->Wd_Get_Api( ).

   CALL METHOD lo_api_controller->GET_MESSAGE_MANAGER
     RECEIVING
       MESSAGE_MANAGER = lo_message_manager
       .

   lt_messages = lo_message_manager->GET_MESSAGES( ).

   describe TABLE LT_MESSAGES.

" Visible area is more than the no. of msgs, so no scroll bar
   lv_msgs_count = sy-tfill + 1.

   wd_context->set_attribute( EXPORTING 
                              name = 'MAX_MSG_VISIBLE'
                              VALUE = lv_msgs_count ).
ENDMETHOD.

Hope this resolves your issue.

Hi

I don't have any option to bind "MaxVisibileMessage", I have highlighted in the attached screen shot.

I removed value for "MaxVisibleMessage", still i'm having dbl scroll bars.

Hi MRA,

Please write the below logic to set the maxVisibleMessages dynamically.

  METHOD WDDOMODIFYVIEW.

   data lo_api_controller     type ref to if_wd_controller.

   data lo_message_manager    type ref to if_wd_message_manager.

   data lt_messages           type if_wd_message_manager=>TY_T_MESSAGES.

   data lv_msgs_count         TYPE i.

   lo_api_controller ?= wd_This->Wd_Get_Api( ).

   CALL METHOD lo_api_controller->GET_MESSAGE_MANAGER

     RECEIVING

       MESSAGE_MANAGER = lo_message_manager

       .

   lt_messages = lo_message_manager->GET_MESSAGES( ).

   describe TABLE LT_MESSAGES.

" Visible area is more than the no. of msgs, so no scroll bar

   lv_msgs_count = sy-tfill + 1.

  data lo_message_area type ref to cl_wd_message_area.

          lo_message_area = view->get_element( 'MSG_AREA').

          if lo_message_area is bound.

                    lo_message_area->SET_MAX_VISIBLE_MESSAGES( value = lv_msgs_count ).

          endif.

ENDMETHOD.

Note: here MSG_AREA is name of message area ui element.

Hope this helps you.

Hi Rama,

data: lo_message_area type ref to cl_wd_message_area.

lo_message_area = view->get_element( 'MSG_AREA').

Error at above highlighted line, the output of view->get_element is not convertible to lo_message_area.

Thanks!!

Hi,

Use casting.

lo_message_area ?= view->get_element( 'MSG_AREA').

Thanks for you reply, but this didn't help.

I'm still having multiple scroll bars.

Hi MRA,

Please replace the line with

lo_message_area ?= view->get_element( 'MSG_AREA').
