Adding rows to a grid. Loading saved file.

Hi all, I am facing two problems. What am i looking for is:

1)Adding row to a grid(with no DS). I have this procedure that starts working when a button "Add" pressed.Then a dialog shows up and there are several fields to fill (like this one govPartAddInfoPanel.govName)

procedure addGovInfoToGrid is
    v_govName varchar2(50);
    v_eventName varchar2(50);
    v_eventDate varchar2(50);
  begin
    v_govName:=FORMSPIDER.api_component.getvaluetx('govPartAddInfoPanel.govName');
     FORMSPIDER.api_component.setvalue('govPartPanel.govGridName',v_govName);
  end;

Here is a grid:

    <grid scrollBarPolicy="WhenNeeded">
      <column headerLabel="№" width="25">
        <textLabel/>
      </column>
      <column headerLabel="Name">
        <textLabel name="govGridName"/>
      </column>
      <column headerLabel="Event name">
        <textLabel/>
      </column>
      <column headerLabel="Date" width="50">
        <textLabel/>
      </column>
    </grid>

For the beginning i want to fill in "name" column. It works, but it fills all the rows in a grid column but i need only one value to append to the grid.

2)Is there any possibility to load saved file in FS in order to let user edit previously filled fields and radio-buttons/checkboxes?
