Problem in capturing Tableview Selectedrow contents

[Former Member]

Hi I am experiencing problem in capturing the contents of the selected row in the tableview. My Code looks like as follows:

<b>Layout</b>

<%@page language="abap" %>
<%@extension name="htmlb" prefix="htmlb" %>
<htmlb:content design="design2003" >
<%--  <%@include file="head.htm" %> --%>

  <htmlb:page title="Company Code Search " >
    <htmlb:form>
      <htmlb:label for      = "l_CCODE"
                   text     = "Field"
                   tooltip  = "User ID"
                   required = "X"
                   width    = "100px"
                   design   = "EMPHASIZED" />
      <htmlb:dropdownListBox id = "ddname">
        <htmlb:listBoxItem key   = "li_bukrs"
                           value = "Company Code" />
        <htmlb:listBoxItem key   = "li_butxt"
                           value = "Company Code Description" />
      </htmlb:dropdownListBox>
      <htmlb:inputField id    = "i_search"
                        value = "Search term" />
      <htmlb:button id      = "b_search"
                    text    = "Search"
                    tooltip = "click here to start the search"
                    onClick = "onInputProcessing(select)" />
      <br>

      <htmlb:tableView id              = "tv_tabid"
                       table           = "<%= gt_t001 %>"

                       tableLayout     = "AUTO"
                       width           = "75%"
                       visibleFirstRow = "1"
                       visibleRowCount = "10"
                       headerVisible   = "TRUE"
                       headerText      = "Company Code Selection Table"
                       onRowSelection  = "onInputProcessing(select)"
                       selectionMode   = "SINGLESELECT"
                       selectedRowKey  = "wa-BUKRS"
                       navigationMode  = "BYPAGE"
                       footerVisible   = "TRUE" >

        <htmlb:tableViewColumn columnName="BUTXT"
                                    title= "Description">
        </htmlb:tableViewColumn>
      </htmlb:tableView>

<b>OnInputProcessing</b>

ENDCASE.

When I selected a row in the tableview, I am getting the selectedrow Index (selectedrowindex = table_event->selectedrowindex.). But the Values in the table gt_t001 are disapperiaring to read the contents by selectedrowindex.

Is there a way of capturing the contents of selected row or if I am doing any wrong in loosing the data from internal table.

Please help.

Hi all,

Thanks For your affort. I solved this problem myself. I was not using keycolumn in the table view. After I use the keycolumn I am getting the value into tv_data->SELECTEDROWKEY from selected row.

Thanks again.

Hi azaz ali,

Yes I tried, didn't work. As I mentioned the problem with the data in my Internal Table. I was able to get the selected row Number/index from tableview, but the problem is with data refreshed in Internal table.

Please Advise the solution.

Thanks,

Hi Gireesh,

I will give you a sample code which i have practiced for the same reqirement...

Oninputprocessing:

if event->name = 'tableView' and event->event_type = 'rowSelection'.

data : data2 type ref to cl_htmlb_tableview.

DATA: tv_data TYPE REF TO CL_HTMLB_EVENT_TABLEVIEW.

data2 ?= cl_htmlb_manager=>get_data(

request = request

name = 'tableView'

id = 'tview' ).

clear tv_data.

if not data2 is initial.

tv_data = data2->data.

clear wa1.

read table it_mara3 into wa1 index tv_data->row_index.

if sy-subrc = 0.

v_matnr1 = wa1-matnr.

call method navigation->set_parameter

exporting

name = 'v_matnr1'

value = v_matnr1.

navigation->goto_page( 'third.htm' ).

endif.

endif.

endif.

where wa1 is a workarea declared as page attribute.

and every thing is correct in layout except one thing that i have added one more attribute to the tableview that is...

onNavigate="onMyNavigation"

ADD THE CODE WHAT EVER REQUIRED BY SEEING THE EXAMPLE GIVEN...YOU WILL GET THE SOLUTION.

Replace this

 READ TABLE gt_t001 INTO wa_t001 INDEX selectedrowindex.

by

<b>

READ TABLE gt_t001  INDEX selectedrowindex
        ASSIGNING <row>.

</b>where <row> is a field symbol of the type of your itab work area.

Do this changes and revert back.

Hope this helps,

Hi Ravikiran,

The Problem is here after I come back from row selection from Tableview, the data in Internal table gt_t001 is refreshing. If I have the data I am able to read the row what I selected based on Selectedrow value from Tableview event.

Any Idea why I am loosing data in my Internal table?.
