#region Methods
public new SalBoolean DataSourcePopulateIt(SalNumber nParam)
{
	#region Local Variables
	// TODO
	#endregion

	#region Actions
	// TODO Logic

	bOk = base.vrtDataSourcePopulateIt(nParam);
	
	// TODO Logic
	
	return bOk;
	#endregion
}

#region Overrides
public override SalBoolean vrtDataSourcePopulateIt(SalNumber nParam)
{
	return this.DataSourcePopulateIt(nParam);
}
#endregion

Example:

#region Methods
public new SalBoolean DataSourcePopulateIt(SalNumber nParam)
{
	#region Local Variables
	SalBoolean bOk = false;
	#endregion

	#region Actions
	using (new SalContext(this))

			DataSourceUserWhere(Ifs.Fnd.ApplicationForms.Const.METHOD_Execute, i_lsUserWhere.ToHandle());
		}
	   else
		{
			i_lsUserWhere = "";
			DataSourceUserWhere(Ifs.Fnd.ApplicationForms.Const.METHOD_Execute, i_lsUserWhere.ToHandle());
		}
	}

	bOk = base.vrtDataSourcePopulateIt(nParam);
