How to handle the current row with radio button selection???

Question

Hi Everyone,
I have one ADF page with one table and one "Find" button.
I have created one new attribute with VARCHAR2(1) in the VO and dragged that attribute as first column in the table. And changed that first column to Radio Button to select only one row at a time.
Upon clicking on the "Find" button i need to get the values of current selected row.
How can i get the values of selected row?
What code should i write to get the values of selected row in Method Binding of "Find" button?
Any suggestions will be really useful.
Thanks.

Hello Kumar,
I have some comments on your case.

1- You should create this attribute in the Entity object and then add it to the view object.
2- Do you need that only one radio button is set at a time for all rows ? If yes then you need to handle the case when the user set more than one row and clear the value of the attribute for all other rows.

How can i get all the values of current row in backing bean method(method binding of Find method)?
can u plz provide me the code for that?

If you mean by the current row is that the row with its value of the selected attribute is set (the radio button is set for that row), then you can write a method in the viewObjectImpl class and expose it to client interface and call it from your bean.
here is an example based in Department table in HR schema.
//This method is written in DepartmentsViewImpl   
public Row getSelectedRadioRow(){
            //create a second row set to not impact the row set used in ADF
            RowSet duplicateRowSet = this.createRowSet("duplicateRowSet");
            //get the current row of the table to set it back after re-executing the VO
            DepartmentsViewRowImpl currentRow = (DepartmentsViewRowImpl)this.getCurrentRow();
            Row[] filteredRows = duplicateRowSet.getFilteredRows("IsSelected", "1");
            DepartmentsViewRowImpl row=null;
            if(filteredRows.length>0){
                row = (DepartmentsViewRowImpl)filteredRows[0];
                System.out.println("Department Name " + row.getDepartmentName());              
            this.setCurrentRow(currentRow);
            duplicateRowSet.closeRowSet();
            return row;           
        }
