How to delete a Selected row from datagrid and how to create a datagrid popup with saved values

hi friends,
              I am new to flex.i am doing a flex4 application,i need help for this.
            i am having a data grid with columns.i have two questions.
           Ques 1: when i selected a partiuclar row from a datagrid and click delete button means that record will delete from the datagrid and DTO from the cloud tables also.
            Ques 2: when i save the data grid values using save button means that data will store in respective cloud DTO which is related to the datagrid,
                My requirement is i am using a search button when i click the search button it will show a datagrid that datagrid will contain the previous datagrid datas which is saved in the cloud.
REQUIREMENT example: first screen: i am using with data grid 3 columns (Student Roll number ,Student Name,Student pecentage)---->save--->data will store in cloud DTO.
Second screen: search button ----> it need show datagrid popup.it will have data which we saved in the first screen with same columns(Student Roll number ,Student Name,Student pecentage).
This is my requirement.
Any suggession welcome.
Thanks in advance.

Lets break the problem statement in multiple steps
1. We need a way to know the selection on all rows.
2. We need the association of the checkBox with the data
The solution is to use a arrayCollection/array that holds all the instances created for checkbox.This collection should be a property of component containing the datagrid. We need to use a custom component implementation or inline ItemRenderer. The way you have used is called dropinItemRenderer. Preferaly use custom component implementation and add the instance to the arrayCollection at CreationComplete. Make sure you use addItemAt so that you add the instance in the same row as the data. To get rowIndex the custom Checkbox should implement IDropInListItemRenderer. You could iterate this collection to check all the instances that are checked.
Note: This is the approach considering your dataprovider doesnt have a selection field.

How to delete a selected row from adf table

Hi
I am using a ADF Table to get data from the database, i need to select a specific row and then delete it how to get
this done.
Thanks in Advance.

Or try this code:
In your backing bean:
    public void deleteRows(ActionEvent actionEvent) {
        ((AppModuleImpl)getApplicationModuleForDataControl()).deleteRowEmp();
    public static Object resolveExpression(String expression)
            try
                FacesContext facesContext = FacesContext.getCurrentInstance();
                Application app = facesContext.getApplication();
                ExpressionFactory elFactory = app.getExpressionFactory();
                ELContext elContext = facesContext.getELContext();
                ValueExpression valueExp =
                    elFactory.createValueExpression(elContext, expression, Object.class);
                return valueExp.getValue(elContext);
            catch (Exception e)
               ;// log you message here
            return null;
         * Get application module for an application module data control by name.
         * @param name application module data control name
         * @return ApplicationModule
        public static ApplicationModule getApplicationModuleForDataControl()
            return (ApplicationModule) resolveExpression("#{data.AppModuleDataControl.dataProvider}");
        }In your AppmoduleImpl:
    public void deleteRowEmp(){
        this.getEmpView1().removeCurrentRow();
        this.getDBTransaction().commit();
    }And another option is to expose the appmodule method as a client and bind to the jspx as a button.

How to delete the selected rows with a condition in alv

dear all,
i am using the code in object oriented alv.
WHEN 'DEL'.
PERFORM delete_rows.
FORM delete_rows.
DATA : lv_rows LIKE lvc_s_row.
data : wa_ROWs like LVC_S_ROW.
FREE : gt_rows.
CALL METHOD alv_grid->get_selected_rows
IMPORTING
et_index_rows = gt_rows.
IF gt_rows[] IS INITIAL.
MESSAGE s000 WITH text-046.
EXIT.
ENDIF.
loop at gt_rows into wa_ROWs .
if sy-tabix ne 1.
wa_ROWs-INDEX = wa_ROWs-INDEX - ( sy-tabix - 1 ).
endif.
delete gt_sim INDEX wa_ROWs-INDEX .
endloop.
the rows to be deleted from int.tab gt_sim not in the alv display.
all the rows should not be deleted if one of the field in gt_sim eq 'R'.
how to check this condition

dear jayanthi,
ok if i am coding like that as u mentioned ,
it will exit the loop when first time the field value is 'R'.
if any of the selected rows contains field value 'R'. it shold not delete all the selected rows.
as u suggested it will not delete after first time the field value is r.
i am deleting it by tab index so,
suppose if i am selecting the row without field value R say its tabix is 1.
the next row with tabix 2 with field value R.
it deletes the first row and exits , it should not delete the first row also.

How to delete the committed row from a table from its VOImpl class ??

I am new to ADF and I have problem to solve. To perform roll back I am using fetching key before roll back and setting it after undo operation, so that I can stay back in the currently selected row. But in my case I am using application model commit for one LOV attribute selection in the row. So when ever I am performing roll back operation after inserting a row, the values other than this committed LOV attribute gets roll backed, but I need remove the entire row from table. Does there any option to remove a row based on the attribute values of a row from VO's row implementation or from bean class in a performance optimized way ?
Thanks in advance..........

Why did you mark it answered but gave no dukes to finalight? That's not how it works.
You should mark his answer as correct and give him at least one duke, for the effort!

How to delete the duplicate rows from the table

Hi,
I have 2 tbales namely component, component_audit
For each record in component table there are multiple entries in component_audit table.
I need to keep the first record and delete the others from the component_audit table
say for example
select a.component_id,a.dt_ti_stamp,a.component_name,a.column_before,b.comments from component_audit a,component b where a.component_id=b.component_id
( on the above result set only I shold apply the actual delete query )
PLease help me in this regards.
Thanks.

delete from component_audit a where dt_ti_stamp not in (select
                                        min(b.dt_ti_stamp)
                                   from
                                        component_audit b
                                   where
                                        a.component_id = b.component_id)

Delete operation is not working to delete selected row from ADF table

Hi All,
We are working on jdev 11.1.1.5.3. We have one ADF table as shown below. My requirement is to delete a selected row from table, but it is deleting the first row only.
<af:table value="#{bindings.EventCalendarVO.collectionModel}" var="row"
rows="#{bindings.EventCalendarVO.rangeSize}"
emptyText="#{bindings.EventCalendarVO.viewable ? applcoreBundle.TABLE_EMPTY_TEXT_NO_ROWS_YET : applcoreBundle.TABLE_EMPTY_TEXT_ACCESS_DENIED}"
fetchSize="#{bindings.EventCalendarVO.rangeSize}"
rowBandingInterval="0"
selectedRowKeys="#{bindings.EventCalendarVO.collectionModel.selectedRow}"
selectionListener="#{bindings.EventCalendarVO.collectionModel.makeCurrent}"
rowSelection="single" id="t2" partialTriggers="::ctb1 ::ctb3"
>
To perform delete operation i have one delete button.
<af:commandToolbarButton
text="Delete"
disabled="#{!bindings.Delete.enabled}"
id="ctb3" accessKey="d"
actionListener="#{AddNewEventBean. *deleteCurrentRow* }"/>
As normal delete operation is not working i am using programatic approach from bean method. This approach works with jdev 11.1.1.5.0 but fails on ver 11.1.1.5.3
public void deleteCurrentRow (ActionEvent actionEvent) *{* DCBindingContainer bindings =
(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding dcItteratorBindings =
bindings.findIteratorBinding("EventCalendarVOIterator");
// Get an object representing the table and what may be selected within it
ViewObject eventCalVO = dcItteratorBindings.getViewObject();
// Remove selected row
eventCalVO.removeCurrentRow();
it is removing first row from table still. Main problem is not giving the selected row as current row. Any one point out where is the mistake?
We have tried the below code as well in deleteCurrentRow() method
RowKeySet rowKeySet = (RowKeySet)this.getT1().getSelectedRowKeys();
CollectionModel cm = (CollectionModel)this.getT1().ggetValue();
for (Object facesTreeRowKey : rowKeySet) {
cm.setRowKey(facesTreeRowKey);
JUCtrlHierNodeBinding rowData = (JUCtrlHierNodeBinding)cm.getRowData();
rowData.getRow().remove();
The same behavior still.
Thanks in advance.

JDev 11.1.1.5.3 sounds like you are using oracle apps as this not a normal jdev version.
as it works in 11.1.1.5.0 you probably hit a bug which you should file with support.oracle.com...
Somehow you get the first row instead of the current row (i guess). You should debug your code and make sure you get the current selected row in your bean code and not the first row.
This might be a problem with the bean scope too. Do you have the button (or table) inside a region? Wich scope does the bean have?
Anyway you can try to remove the iterator row you get
public void deleteCurrentRow (ActionEvent actionEvent) { DCBindingContainer bindings =
(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding dcItteratorBindings =
bindings.findIteratorBinding("EventCalendarVOIterator");
dcItteratorBindings.removeCurrentRow();Timo

Need sample code to get handle of Selected rows from ADF Table

Hi,
I am new to ADF. I have an ADF table based on VO object.On some button action,I need to get handle of selected rows in application module.
If anybody is having sample code to do this then please share with me.
Thanks,
ashok

wow now link http://blogs.oracle.com/smuenchadf/examples/#134 is working.thanks a lot.
also the link http://baigsorcl.blogspot.com/2010/06/deleting-multi-selected-rows-from-adf.html is very useful. Thanks a lot for Sameh Nassar too.He made it clear that in 11g Select column is not available for a ADF table and provided a solution to get Select column.

Please suggest me how to proceed.
Please provide me some sample code.Its not working
I tried with these code:-Its not working-->

                         Insert Colum , in that column, next insert celleditor , of type text view , bind the property text -- to "name " of Table node of the context
           Insert Colum , in that column, next insert celleditor , of type text view , bind the property text -- to "no " of Table node of the context
// create a action "removeElement"
// create a button "Remove Element " --> Event action -- removeElement
// under the action write down the code :
public void onActionremoveElement(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionremoveElement(ServerEvent)
    // before removing display elements
    wdComponentAPI.getMessageManager().reportSuccess("Before deletion :");
