var fieldCombo = new Ext.form.ComboBox({
    id: 'fieldNameCombo,
    name: 'columnName',
    typeAhead: false,
    displayField:'GRPBYNAME',
    valueField:'GRPBYID',
    queryMode:'local',
    width:140,
    allowBlank: false,
    emptyText: 'Select search field',
    renderTo: 'fieldNameBox',
    store:{
        xtype:'Store',
        fields:[
            {
               type:'string',
               name:'GRPBYID'
            },
            {
               type:'string',
               name:'GRPBYNAME'
            }
        ],
        data:[
            {
               'GRPBYID':'TEXT',
               'GRPBYNAME':'Name'
            },
            {
               'GRPBYID':'TEXT',
               'GRPBYNAME':'Address'
            },
            {
               'GRPBYID':'DATE',
               'GRPBYNAME':'Date'
            },
            {
               'GRPBYID':'NUMBER',
               'GRPBYNAME':'Number'
            },
            {
               'GRPBYID':'DATE',
               'GRPBYNAME':'Time'
            }
        ]
    }
});

I have the above code,In that code i assigned GRPBYID as the value field. The data which comes from server has same GRPBYID value for different display names.The problem is that when i try to select different display name with same value combo box is not selecting the new display field.

Please suggest if there is any mistake in the code.

You can't have the value in your valueField repeated across multiple records. It has to be unique within that store.
