filtering the data(record) based on selected Input

For filtering a particular record    :

1.First create a table  i.e tabcust  with fields name , ids(baseenum) ,  phno , height , weight
2.create a form and drag the table tabcust into data source.
in design take a grid and a combo box   give enum type as baseenum1;

1. In class:

public class FormRun extends ObjectRun
{
QueryBuildRange qbr2;  //  declartion of range variable
}

1. In Data source level . Override a method init()
   public void init()
   {
   super();
   qbr2 = this.query().dataSourceName(“tabcust”).addRange(fieldNum(Tabcust , BaseEnum1));
   }

5.in combo box – in methods override a selectionchange method()
public int selectionChange()
{
int ret;
ret = super();
Tabcust_ds.executeQuery();
return ret;
}

1. Create a range by  overriding method executequery() in data source level: 

public void executeQuery()
{
qbr2.value(combobox.valueStr());
super();
}
