Selection in MULTISELECT tableview is getting retained

[Former Member]

Hi,

I have a TableView with selection mode MULTISELECT.

<htmlb:tableView id = "TVTABLE"

selectionMode = "MULTISELECT"

visibleRowCount = "20"

sort = "SERVER"

filter = "SERVER"

tabIndexCell = "TRUE"

table = "//mr_model/mt_table"

visibleFirstRow = "<%= controller->mv_table_first_row %>"

iterator = "<%= mr_iterator %>" />

I select some rows and make a server roundtrip from this page back to the same page. The row selection is retained even after the roundtrip.

Why is this so? If this is the standard behaviour, then is there any way to refresh the selection?

Pls note that I'm not using the selectedRowIndexTable or selectedRowKeyTable attributes.

Hi Pradeep,

Here is the code...!!

cl_htmlb_manager=>check_tableview_all_rows( rowcount = n
request = request
id = '<tableview id>'
keytable = keytable "Table containing the key values of your itab
check = '' ). "If its 'X' all items will be selected and ' ' will uncheck all items.

Hi Tatvagna,

Hi,

Where have you used this code....

Is your application statefull ?? If so what you can do is that you can set a FLAG, and post this in the onCreate event by doing SWITCH-CASE on the FLAG.

It should work....works for me though...!!

If it is till not working, post your code here and let us have a look.

I placed this code in the DO_HANDLE_EVENT of the controller.

If the above mentioned solutioin doesn't work use this code. for sure it will work

In the defination you should have

      <htmlb:tableView id              = "TVTABLE"
                       selectionMode   = "MULTISELECT"
                       visibleRowCount = "20"
                       sort            = "SERVER"
                       keyColumn       = "PERNR"
                       filter          = "SERVER"
                       selectedRowKeyTable = "<%=key_tab%>"
                       tabIndexCell    = "TRUE"
                       table           = "<%=lt_01%>" />

Key Column and Selected Row Table

AND

in the handle event you should play with

 DATA: lr_event        TYPE REF TO if_htmlb_data,
        lr_ana_tv       TYPE REF TO cl_htmlb_tableview,
        lr_ana_tv_data  TYPE REF TO cl_htmlb_event_tableview.

* load htmlb_manager
 CLASS cl_htmlb_manager DEFINITION LOAD.

* try to get a normal event
 lr_event = cl_htmlb_manager=>get_event( request ).

*try to get extended event
 IF lr_event IS INITIAL.
   lr_event = cl_htmlb_manager=>get_event_ex( request ).
 ENDIF.

* check if system have send an event
 IF lr_event IS INITIAL.
   RETURN.
 ENDIF.

 lr_ana_tv ?= cl_htmlb_manager=>get_data(
                request      = runtime->server->request
                name         = 'tableView'
                id           = 'TVTABLE' ).
 lr_ana_tv_data = lr_ana_tv->data.
* you can refresh the selected row table how so ever you want...
refresh lr_ana_tv->data->PREVSELECTEDROWINDEXTABLE[].
refresh lr_ana_tv->data->PREVSELECTEDROWKEYTABLE[].

hope this helps.
