Filtering the data(record) based on selected Input in Ax

For filtering a particular record    :

1.First create a table  i.e TableName   with fields name , Ids(Base enum) ,  Phno , Age

2.Create a form and drag the table TableName into data source.
in design take a grid and a combo box   give enum type as baseenum 

3.In class:
       public class FormRun extends ObjectRun
       {
             QueryBuildRange qbr2;  //  declartion of range variable
       }

4.In Data source level . Override a method init()

1. public void init()
   {
         super();
        qbr2 = this.query().dataSourceName(“Datasourcename”).addRange(fieldNum(TableName, BaseEnum1));
   }

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

6.Create a range by  overriding method executequery() in data source level: 
       public void executeQuery()
       {
           qbr2.value(comboboxName.valueStr());
           super();
       }

Note

     Set Auto Declaration :Yes for Combo box
