Button column in tableview

Hi All,
I've got a tableview that I've added a button column onto. The button runs the onRequestClick() method fine but I need to know which particular button was clicked ( on which row ).
The button has been created using the code :
col = model.getColumn("REQUEST");
col.setTitle(bean.getChangeOrderRequestText());
col.setCellType(-1, TableColumnType.BUTTON);
col.setOnCellClick("requestClick");
The event handler is :
public void onRequestClick(Event event) {
//TableHeaderClickEvent tne = (TableHeaderClickEvent) event;
How can I tell which of the 10 buttons ( 10 rows in the tableview) was clicked.
Cheers
Richard

Hi Richard,
probably clicking the button raises a TableCellClickEvent. You can retrieve the visible Rownumber by
TableCellClickEvent cellClickEvent = (TableCellClickEvent)event;
int visibleClickedRow = cellClickEvent.getVisibleRowIndex();
Then you have to add the firstVisibleRowNumber in case your table has more than one page, but I don't know the details for sure right now.
Hope that helps.

Could anybody provide a code sample on how to create a BEFORE INSERT trigger , which calculates the value of the column UN_123 based on the values of C_1, C_2 and C_3 ??

Push button column in table control

Hi,
I have to add a few push button columns into table control. This columns has to be placed between fields of DDic table. How to do this? Shall I create new DDic structure with all the needed fields from DDic table and add also fields for push button columns? Which data element shal I use in this case for push button field? Or is the better solution to add DDic table fields one by one and then using drag and drop technique to add push button column behind it?
Thanks.

Hi ,
Your Last option is better first add columns into DDIC table then Drag and
Drop it on table control .
That will better definitely.................................
if useful rewards the point..............
Thanks .

Thank You.
Hello,
You could get that task done inside its cellcontent_click event, because we could get the rowindex of that row which we clicked. You could refer to the sample below.
Private Sub DataGridView1_CellContentClick(sender As Object, e As DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
Dim senderGrid = DirectCast(sender, DataGridView)
If TypeOf senderGrid.Columns(e.ColumnIndex) Is DataGridViewButtonColumn AndAlso
(e.RowIndex >= 0 And e.RowIndex < senderGrid.RowCount - 1) Then
If MsgBox("Would you like to remove this row?", MsgBoxStyle.YesNo, "Delete Row") = MsgBoxResult.Yes Then
senderGrid.Rows().RemoveAt(e.RowIndex)
End If
End If
End Sub

I am having problem in populating data from a table in one screen to a Text Field in the other screen. I have two classes FirstClass containing a textbox and a button. On pressing a button a second window is opened containing a Table of values. As the user double clicks a row the value of the second column of the row should be inserted into the textbox of the FirstClass. Code of both the classes is attached. Thanking you in anticipation.

Image Column in Tableview

Hi all,
here's the thing: I'm trying to add an image column to a tableview but it doesn't work (there's no error, but the image doesn't appear). I've tried it with an iterator.
Page Layout:
<%@page language="abap" %>
<%@extension name="htmlb" prefix="htmlb" %>
<htmlb:content design           = "design2003"
               controlRendering = "SAP" >
<htmlb:document>
    <htmlb:documentHead>
    </htmlb:documentHead>
    <htmlb:documentBody>
      <htmlb:form>
        <htmlb:tableView id            = "tableview_scarr"
                         table         = "<%= pa_tab_scarr %>"
                         headerText    = "Table SCARR"
                         headerVisible = "TRUE"
                         iterator      = "<%= application %>" >
        </htmlb:tableView>
        <%
IF page->messages->num_messages( ) > 0.
        %>
        Error
        <%
ENDIF.
        %>
      </htmlb:form>
    </htmlb:documentBody>
</htmlb:document>
</htmlb:content>
OnInitialization:
SELECT * FROM scarr INTO TABLE pa_tab_scarr.
My application class is my iterator. It implements GET_COLUMN_DEFINITIONS:
METHOD if_htmlb_tableview_iterator~get_column_definitions.
DATA tv_column TYPE tableviewcontrol.
tv_column-columnname          = 'SHOW_ICON'.
tv_column-title               = 'SHOW_ICON'.
tv_column-encode = 'X'.
tv_column-width               = '100'.
APPEND tv_column TO p_column_definitions.
CLEAR tv_column.
tv_column-columnname          = 'CARRID'.
tv_column-width               = '100'.
APPEND tv_column TO p_column_definitions.
ENDMETHOD.
...and it implements RENDER_CELL_START:
METHOD if_htmlb_tableview_iterator~render_cell_start.
CASE p_column_key.
    WHEN 'SHOW_ICON'.
      DATA col_image TYPE REF TO cl_htmlb_image.
      CREATE OBJECT col_image.
      col_image->src = "@2N@".
      col_image->width = '16'.
      col_image->height = '14'.
      p_replacement_bee = col_image.
ENDCASE.
ENDMETHOD.
I've checked the SICF, but all services concerning icons are activated. This is my first Iterator so i'm not sure if i've forgotten something. Why the image is not shown?
Regards
Mark-André

Hi Mark,
First of all, define an object named iterator in page attributes type ref to iterator_class_name
i.e
iterator TYPE REF TO ZCL_ITERATOR(or iterator_class_name)
Then in <b>onInitialization</b> use
create object iterator.
Also you can use any name of the iterator object...but the name application is reserved for the application class....
So your tableView code will be
        <htmlb:tableView id            = "tableview_scarr"
                         table         = "<%= pa_tab_scarr %>"
                         headerText    = "Table SCARR"
                         headerVisible = "TRUE"
                         iterator      = "<%= iterator %>" >
Rest all is fine...!!
Hope this helps.

Set filter for only one column in tableview

Hi
i am using in MVC a htmlb:tableview with filter in only one column of 8.
This is all working fine, except that the user can enter a searchsting in the filterfield for all columns, but in handle_event (of the controller) ; i only react to a text in the filterfield of column 4 and ignore all other filtertext , which were maybe entered in the other columns.
My question:
how can i enter the filter only for one column, in a way that the user cannot enter any text in the filterfield of the other columns, only in column 4 ?
my view:
<htmlb:tableView id             = "requirements"
                 table          = "//model/pdst_reqs"
                 filter         = "APPLICATION"
                 keyColumn       = "EXTID"
                 iterator        = "<%=model%>"
                 footerVisible   = "FALSE"
                 encode          = "TRUE"
                 visibleRowCount = "<%=model->rowcount%>"
                 width           = "100%"/>
Best Regards
Britta

You can disbale the Filter for the particular column by setting the DISABLE_FILTER in the Iterator method IF_HTMLB_TABLEVIEW_ITERATOR~GET_COLUMN_DEFINITIONS. Here is the sample code
method IF_HTMLB_TABLEVIEW_ITERATOR~GET_COLUMN_DEFINITIONS .
CLEAR p_column_definitions.
CLEAR p_overwrites.
data tv_column TYPE TABLEVIEWCONTROL.
tv_column-COLUMNNAME          = 'FLDATE'.
tv_column-SORT                = 'X'.
tv_column-EDIT                = 'X'.
tv_column-ONCELLCLICK         = 'MyCellClick1'.
tv_column-title               = 'Date '.
APPEND tv_column TO p_column_definitions.
CLEAR tv_column.
tv_column-COLUMNNAME          = 'PRICE'.
tv_column-horizontalAlignment = 'right'.
tv_column-verticalAlignment   = 'middle'.
tv_column-ONCELLCLICK         = 'MyCellClick2'.
tv_column-title               = 'Currency'.
tv_column-EDIT                = 'X'.
tv_column-DISABLE_FILTER      = 'X'.    " <-------Like this
APPEND tv_column TO p_column_definitions.
endmethod.
Hope this will solve your problem.

Add Button Column in IR

Hi,
I have created an Interactive report on a table. I want to add two buttons in each row: Accept and Reject, so that i can change the status(db column) of the corresponding record on button action.
How can I do so?

Hi poojaC,
Try the below code,
i am giving the idea to add buttons..may be this is not the way you want.
step1
-- put this code in report region
select "ROWID",
'<input type="button" value="Accept" onclick="func('||EMPNO||')">' as "Accept",
'<input type="button" value="Reject" onclick="func('||EMPNO||')">' as "Reject",
"EMPNO",
"ENAME",
"JOB",
"MGR",
"HIREDATE",
"SAL",
"COMM",
"DEPTNO"
from "#OWNER#"."EMP"
-- edit the Accept and reject column and change Display type to "standard report column"Step 2 : create one function in page header like
-- here you can execute your process on button action
<script>
function func(id)
alert(id);
</script>Hope this will give you some idea.

Jitendra

How to avoid the page to move up when I click the button on the Tableview?

Hi, EP fellows.
I currently have 3 tableViews and 1 header form set in one jsp page (I know, it may not be a good design to put three tableView in one jsp page.....but for the sake of avoiding client side eventing between each tableViews..I combined them into one jsp page). I set the Load/Navigation value to be URL.
Here is the problem. Everytimes I click on the Navigation button (Up/Down) to navigate the tableView data to another page, the whole page will move up and away from the table that I navigating.
I know it is bacause the page get refreshed, and go to the first item of the page. In this case, how do I avaoid the page to move up and away form the tableView? As it is really look bad when user click on the button, they have to scroll back to the tableView they click.
Thanks for advices.

javascript: document.execCommand('SaveAs','1',null);
But i m not sure will it pop up for pdf, just try to google javascript to save a pdf file.

Radio button column in the tabular report

Hi everyone,
I have a tabular report. I wanted to have radio button and check box some of the field. Please take a look at my sample application.
http://apex.oracle.com/pls/otn/
Workspace ==> SHYIN
username ==> SHY
password ==> shy
Application ID : 29879 - TabularForm
On page 2, of the detail form, I want to have radio button in Primary Contact column and check box in status column. I would appreciate any suggession. Thanks.
SHY

Hi Andy,
I surely come back with new question!
Now, I am trying to change the status column to check box. I can see the correct status the check box in the form. But when I tried to add new rows or update anything, I am getting "No data found" error.
here is my query
SELECT
APEX_ITEM.HIDDEN(1, SEQ_ID) || APEX_ITEM.HIDDEN(2, C001) || APEX_ITEM.RADIOGROUP(3, C001, NULL, NULL, 'onclick="javascript:$x(''P2_SELECTED_ID'').value=' || C001 || '"') PRIMARY_CONTACT,
apex_item.text(4,C002) name,
apex_item.text(5,C004) phone,
APEX_ITEM.HIDDEN(6, C006) || apex_item.checkbox(7,C001, null, C005) INACTIVE
from apex_collections
where collection_name = 'C_CONTACT_INFO'
this is the updated Contact_Collection
begin
IF NOT APEX_COLLECTION.COLLECTION_EXISTS('C_CONTACT_INFO') THEN
apex_collection.create_or_truncate_collection(p_collection_name => 'C_CONTACT_INFO');
for y in (select ID,
NAME,
PRIMARY_CONTACT,
PHONE,
decode(STATUS, 'I', ID, null) status,
CUSTOMER_ID
from CONTACTS
where CUSTOMER_ID = :P2_CUSTOMER_ID)
LOOP
apex_collection.add_member(
p_collection_name => 'C_CONTACT_INFO',
p_c001 => y.ID,
p_c002 => y.NAME,
p_c003 => y.PRIMARY_CONTACT,
p_c004 => y.PHONE,
p_c005 => y.STATUS,
p_c006 => y.CUSTOMER_ID);
end loop;
END IF;
end;
here is my updated Update_Collection process
DECLARE
V_C003 CHAR(1);
V_C001 NUMBER;
V_C005 CHAR(1);
BEGIN
FOR X IN 1..APEX_APPLICATION.G_F01.COUNT
LOOP
V_C001 := APEX_APPLICATION.G_F02(X);
IF V_C001 = :P2_SELECTED_ID THEN
--HTP.P('YES');
V_C003 := 'Y';
ELSE
--HTP.P('NO');
V_C003 := 'N';
END IF;
if APEX_APPLICATION.G_F07(X) = APEX_APPLICATION.G_F02(X) THEN
V_C005 := 'I';
ELSE
V_C005 := 'A';
END IF;
APEX_COLLECTION.UPDATE_MEMBER (
P_COLLECTION_NAME => 'C_CONTACT_INFO',
P_SEQ => APEX_APPLICATION.G_F01(X),
P_C001 => APEX_APPLICATION.G_F02(X),
P_C002 => APEX_APPLICATION.G_F04(X),
P_C003 => V_C003,
P_C004 => APEX_APPLICATION.G_F05(X),
P_C005 => V_C005,
P_C006 => APEX_APPLICATION.G_F06(X));
END LOOP;
END;
I did not make any changes to Save_Contacts process.
Thanks

Color a column based on value in another column in tableview

I am using a tableview iterator to display data in a bsp page. I want to color a cell in particular column (column 4), when a value in another column (column 2) on that same row is greater than 20. I can color the cell in column 2 but am not able to color the cell in column 4. How can I accomplish this?
This is what I have. Looks like val1 is losing it's value.
CASE p_column_index.
    WHEN 2.
      ASSIGN p_row_data_ref->* TO <row>.
      ASSIGN COMPONENT 'ZTGT' OF STRUCTURE <row> TO <col>.
      VAL = <col>.
      IF VAL GT '20'.
        val1 = p_row_index.
        p_style = 'celldesign:CRITICALVALUE_DARK'.
      ENDIF.
    WHEN 4.
        if p_row_index = val1.
          p_style = 'celldesign:CRITICALVALUE_DARK'.
        endif.
    WHEN OTHERS.
do nothing
ENDCASE.

The reason val1 is "loosing its' value" is presumably because you have defined it in the method as a local variable. So each time you call the RENDER_CELL_START method it is is newly initialised. So if you make this an instance attribute it will retain its' contents across method calls.

      condense row_index.
      concatenate `openF4Window('` row_index `','` p_cell_id `');` into javascript.
      col_inputField->onValueHelp = javascript.
      _value = p_row_index.
      condense _value.
      concatenate 'flights[' _value '].connid' into attribute_path.
