showRowKey functionality

How to create showRowKey functionality in ADF (ADF table rowkey/RowKey)

If you want to create a showRowKey functionality in ADF through managed bean, here is the way :

showRowKey is a cool functionality which leverage the user to easily navigate to a particular row within the table. If the table consist of thousand of rows, user can easily navigate to row which he is interested on.

As a first step, you  have to populate the table with rows using TreeModel. Then, use the below code to implement the showRowKey functionality.

  public void displayRowKey(ActionEvent event)
  {
    UIComponent parentComponent = event.getComponent().getParent();
    UIComponent table =  parentComponent.findComponent("<table_id>");
    // clear out the displayRow first
    _setCurrentDisplayRow(null, table);
    EditableValueHolder edit = (EditableValueHolder)
                  parentComponent.findComponent("rowKeyValue");
    Object rowKey = edit.getValue();
    if(rowKey != null)
    {
      if(table instanceof RichTable)
        ((RichTable)table).setDisplayRowKey(new Integer(rowKey.toString()));
      else
      {
        String[] keys = rowKey.toString().split(",");
        List<Integer> treeKeys = new ArrayList<Integer>(keys.length);
        for(String key: keys)
        {
          treeKeys.add(new Integer(key));
        }
        if(table instanceof RichTreeTable)
          ((RichTreeTable)table).setDisplayRowKey(treeKeys);
        else if(table instanceof RichTree) {
            ((RichTree)table).setScrollTop(100);
            ((RichTree)table).setScrollTopRowKey(treeKeys);
          ((RichTree)table).setDisplayRowKey(treeKeys);
          
        }
      }
    }
  }

  private void _setCurrentDisplayRow(String displayRow, UIComponent table)
  {
    if(table instanceof RichTable)
    {
      ((RichTable)table).setDisplayRowKey(null);
      ((RichTable)table).setDisplayRow(displayRow);
    }
    else if(table instanceof RichTreeTable)
    {
      ((RichTreeTable)table).setDisplayRowKey(null);
      ((RichTreeTable)table).setDisplayRow(displayRow);
    }
    else if(table instanceof RichTree)
    {
      ((RichTree)table).setDisplayRowKey(null);
      ((RichTree)table).setDisplayRow(displayRow);
    }
  }

ADF MODEL - VIEW CRITERIA (VC)

Image
ADF View Criteria: VIEW CRITERIA is nothing but a "Where" clause to the SQL query with some special functions". It will be used to refine the query results. View Criteria Types: =============== 1. Implicit View Criteria: Renders all the areas in the VO as a filter field. (Default) 2. Named View Criteria: Selected fields are participating in the filter fields section as per the configuration.    Key Technical Term: -------------------------- What is RowMatch :             RowMatch is nothing but "in-memory row filtering" OR CACHE What is Mode : [Filtering Option]            Query/Database - Use query's where clause. [Default]            Cache - In memory filtering            Both  - Use query or memory filtering. What is Bind Variables:           Parameters applied to querie...

Best Practices

Best Practices & Notes:  =================== please watch every day update : ------------------------------------- ADF - TABLE : Primary Key While working with table, ADF always expects a predefined primary key for the table.  We can create a primary key using DB sequence or other alternative options. If you do not have a PK for a table, during scrolling or selecting a row within the table or creating an empty row and scrolling to next set of rows, we will get a weird result. Example for Sequence PK: (Groovy Expression) (new oracle.jbo.server.SequenceImpl("TEST_SEQ",adf.object.getDBTransaction())).getSequenceNumber() Just a note: ADF - TABLE : Custom Partial Trigger We can add table selection listener programmatically with declarative component using the following snippets  of code : _getTable().addSelectionListener(new SelectionListener(){             @Override ...
