How to hide selected rows on Dashboard

Hello.
Assume there is table having about 10 rows. The goal is to let the user select random rows, click on them and make them disappear from the dashboard.
The user wants to export the dashboard to PDF but each time he needs to hide some of the table rows before export is done. There is no rule which rows should be hidden and which should be visible - user selects rows randomly, based on his current needs (or maybe based on the current weather and his grandmother shoe size, i don't know.)
Is there a way to achieve this?
Thanks for your help.

First the quick answer: no, you can't select a row and make it disappear. But depending on how many columns are in the report and whether every instance of a certain type of row needs to be deleted, you can try this:
I'll take the worst case scenario. Every column in the report can have multiple values that need to be excluded.
1) Build multi-select prompts on each column with the operand "not in/not equal to."
2) Put "Is prompted" on all the columns.
When the user discovers a value in a column that makes him want to get rid of that row (and all rows with that value), he can select it in the prompt. When he hits the "Go" button, the prompts will filter out all those rows.
If each row is completely independent of all other rows, then you're out of luck. I would say, download the report in Excel. Delete rows, then convert to pdf.

DATA index TYPE i.
* navigate from <CONTEXT> to <NODE> via lead selection
lo_nd_node = wd_context->get_child_node( name = wd_this->wdctx_node ).
lo_el_node = lo_nd_node->get_lead_selection( ).

How to get selected row keys from RichSelectManyCheckbox

Adf Table has getSelectedRowKeys but SelectManyChekcbox does not has anything similar. Can you tell me how to get selected row keys programmatically for RichSelectManyCheckbox?

Hi User,
selectManyCheckbox component's value property holds the selected items values. Bind this property to some bean variable(of type list) so that you can get the selected values by accessing the bean property.

How to edit selected rows in a datagrid?

Hi all,
I am new to flex and I would like to know how to edit
selected rows( through check boxes) in a data grid. As of now the
whole data grid becomes editable.

This is not simple in Flex 2.0.
You will need to use a custom itemRenderer.
Search the net, perhaps someone has a component or sample
close to what you want.

How to hide zero rows from a structure

Hi
I have a month structue in rows which consists of 36 months. In the keyfigure coulmn also I have a structure with 6 keyfigures. In normal circumstances there will be values only upto 12 or 15 months. I want to hide the remaning rows. Is it possible.
I created a counter on one important keyfigure so that when value>0 it is 1 otherwise 0. I call this counter. Then I tried to create a condition to show only the 1. But while creating the condition after the keyfigure a column for month with the different elements of structure has to be selected. And of course the condition does not work.
Any suggestions how to hide the zero rows of structure
Ram

Right click on the key figure structure and characterstic structure select 'Properties' and check the option 'Also use Zero Suppression for Structure elements'.
Also from the query properties select the 2nd tab display and select the option Suppression "Active All Values = 0" and from Effect on Select "Rows and Columns".
Thanks.

How to hide selection column from alv grid

hi
i want to hide selection columns form alv grid.. how can i do it.. Is there any fm for that?
regards
palak

Hi,
the ALV Grid Control allows you to directly hide key columns with NO_OUT (field KEY_SEL is not used).
Field name:NO_OUT
Comp. type:LVC_NOOUT
Dtype(length):Char(1)
SPACE, 'X'
If you set this field, you hide the relevant column in the list. Nevertheless, the column is available in the field selection and can be interactively selected by the user as a display field. The ALV displays the contents of hidden fields on the detail screen for a row in the grid control.

Neenu.

How to get selected row from a non-bind ADF table

Hi,
I have an ADF table that is based on a collectionModel built programmatically. The collectionModel is this:
model = new SortableModel(new ArrayList<ArrayList>());
Hence, it is not a binding table. My question is how to get the selectedRows from a non-bind table.
I am used to building binding ADF table and I know we can get it from voiterator.getCurrentRow, since the selectionListener is set to the binding....collectionModel.makeCurrent
<af:table value="#{bindings.ItasLookupTypesVO1.collectionModel}"
selectedRowKeys="#{bindings.ItasLookupTypesVO1.collectionModel.selectedRow}"
selectionListener="#{bindings.ItasLookupTypesVO1.collectionModel.makeCurrent}"
</af:table>
I am thinking maybe I need to write my own selectionListener, but need more advice/ideas of what's the codes in the customer selection Listener to get it from my SortableModel.
Please help.
Thanks
-Mina

I'm not sure if this works in your case, but check out the selection listener I write in this blog http://wp.me/pcBZk-eu
You should use the selection event and check the added set. This should give you access to the selected row.

How to get selected Row Index in a table based ona VO?

Hi All,
I'm writing an ADF form wherein I use a VO based on a SQL query. I'd like to know how to get the index of a selected row. I havea selection Listener in place where I can print the selected Row's data using getSelectedRowData().toString() on the table.
How can I get certain Attributes from this selected row.
One solution I thought of is to get the row index and then read attributes. But I cant seem to figure out how to get rowIndex for a selected row. Any sugestions?
Using JDeveloper 11g.
Thanks
P.

If your selected row is marked as current row you can use
// Get a attribute value of the current row of iterator
DCIteratorBinding iterBind= (DCIteratorBinding)dcBindings.get("testIterator");
String attribute = (String)iterBind.getCurrentRow().getAttribute("field1");Where 'testIterator' is the name of the iterator you use for the table and 'field1' is the name of an attribute you want to get.
Or you can iterate over the selected row keys (even if it's only one):
// get selected Rows of a table 2
for (Object facesRowKey : table.getSelectedRowKeys()) {
table.setRowKey(facesRowKey);
Object o = table.getRowData();
JUCtrlHierNodeBinding rowData = (JUCtrlHierNodeBinding)o;
Row row = rowData.getRow();
TestRow testRow = (TestRow)((DCDataRow)row).getDataProvider() ;
}Where TestRow is the row type of the VO of your table.

How to get selected row data of an ADF table in HashMap?

Hi,
Can anyone please tell me how to selected row data of an ADF table in HashMap like :
Object obj = pageTable.getSelectedRowData();
JUCtrlHierNodeBinding rowData = (JUCtrlHierNodeBinding)obj;
Now in above code I want the convert rowData in HashMap.
Can anyone please tell me how to do that? Its urgent.
Thanks,
Vik

Vik,
No need to ask the same question 3 times...
In [url http://forums.oracle.com/forums/message.jspa?messageID=4590586]this post, Nick showed you how to get the Row.
If it were so urgent, you could have done a little reading of the javadocs to come up with code like this (not tested, up to you to do that)
HashMap m = new HashMap();
Row r = get it like Nick showed you to;
Object values[]=r.getAttributeValues();
String names[]=r.getAttributeNames();
for (int i=0; i<r.getAttributeCount(); i++)
m.put(names, values[i]);

How to control selected row in result table on a search page?

Using JDeveloper 10.1.3.2.0
I have attempted to create an ADF page that contains a search and result table in the same page.
I have questions related to the result table. Let's say the result table shows 10 rows per page.
If I page forward there is no default selected row "clicked" on the page. Only if you return to
the very first 10 rows do you see a default selection in row number one of the results.
How would I go about making the first row of each page the default selection?

You'll need to code this into the RangeChangeEvent event of the table.
http://www.oracle.com/technology/products/jdev/htdocs/partners/addins/exchange/jsf/doc/apidocs/oracle/adf/view/faces/component/core/data/CoreTable.html
That said - I'm not sure this will be very helpful for the end user - after all in any case they'll need to first select a row before doing an operation on it.

How To Edit Selected Row In ALV Table

Hello Experts,
In My Webdynpro Application, I am displaying records from database table into an ALV Table.
I want to edit only selected record from ALV table.
Please Suggest How to achieve this.
Thanks,
Pratibha

The link given above is for the UI element 'Table' and does not pertain to ALV.
To Make an ALV Editable on lead selection for that particular lead selected row.
1. The ALV should be made lead selectable, when initializing
2. The ON_LEAD_SELECT function should be invoked.
3. Withing this function the index has to be retrieved to know which row was selected.
4. Based on the index retrived all the columns have to pass FALSE to read_only in the column properties.

Improving performance:How to know selected rows in af:table through chk box

Hi,
I've a VO which has 3 transient variables. 2 of these transient variables getting the values from a view accessor. Using the other transient variable in the Ui to select the rows in the af:table.
In my UI, I've a table and a Check Box to select the rows. I want to get the selected rows through the check box, in the backing bean for my business requirements.
I've used below logic to get the selected rows. Here, I am iterating through the entire viewobject rows, so it is impacting the performance of the UI. How can I know the selected rows in the bean? or How can I improve the performance?
I also applied below view criteria, but still its not performant.
// ViewCriteria vc = vo.createViewCriteria();
// //.getViewCriteriaManager().getViewCriteria("SelectedMerchantCriteria");
// ViewCriteriaRow vcr = vc.createViewCriteriaRow();
// vc.setCriteriaMode(ViewCriteria.CRITERIA_MODE_CACHE | ViewCriteria.CRITERIA_MODE_QUERY);//MerchantName1
// //vcr.setAttribute("MerchantName1", "1017 CAFE");
// vcr.setAttribute("SelectToMap", "true");
// vc.addRow(vcr);
// vo.applyViewCriteria(vc);
// vo.executeQuery();
public void mapSupplierMerchant2(ActionEvent actionEvent) {
// Add event code here...
OperationBinding method = null;
AdfFacesContext adfFacesContext = AdfFacesContext.getCurrentInstance();
Map pageFlowScope = adfFacesContext.getPageFlowScope();

// vc.setCriteriaMode(ViewCriteria.CRITERIA_MODE_CACHE | ViewCriteria.CRITERIA_MODE_QUERY);//MerchantName1
// //vcr.setAttribute("MerchantName1", "1017 CAFE");
// vcr.setAttribute("SelectToMap", "true");
// vc.addRow(vcr);
// vo.applyViewCriteria(vc);
// vo.executeQuery();
List<JUCtrlHierNodeBinding> merchantList = (List<JUCtrlHierNodeBinding>)tableBinding.getChildren();
JUCtrlHierNodeBinding merchantNode = null;
List supToMap = new ArrayList();
boolean isMerchantSelected = false, isMasterSup = false;

Hi
Please check this post [http://adfwithejb.blogspot.in/2012/08/hi-i-came-across-one-common-use-case.html].
It has clear explanation of how to provide a checkbox for selection of rows. You can also go through my comments at the end of the post. That should solve your problem of iterating through the entire VO.
