Hi Mr.Senthil, Try This.

In ZUL..

<combobox id="cmbx_patient">
   <comboitem label="Patient1Name" value="patient1id">
   <comboitem label="Patient2Name" value="patient2id">
</combobox>

In Java Class..

cmbx_patient.addEventListener(Events.ON_SELECT, new EventListener() {
        public void onEvent(Event evt)throws Exception
        {
           cmbx_patient.setValue(cmbx_patient.getSelectedItem().getValue()+"");
        }
    });

Greetings...

M Varun.

Combobox will take the label of selected Comboitem as its value, you can use a custom comboitem to render what you want as below:

test.zul

<zk>
    <window apply="org.zkoss.bind.BindComposer"
        viewModel="@id('vm') @init('test.TestVM')">
        <combobox model="@load(vm.patientModelList)"
            value="@bind(vm.patientCode)"
            width="85px" mold="rounded"
            autodrop="true" autocomplete="true">
            <template name="model">
                <comboitem use="test.CustomComboitem" label="@load(each.code)"
                    displayLabel="@load(each.formattedName)" />
            </template>
        </combobox>
    </window>
</zk>

TestVM.java

package test;

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;

import org.zkoss.zul.ListModelList;

public class TestVM implements Serializable {
    ListModelList _patientModelList;
    private String _patientCode = "";
    public ListModelList getPatientModelList () {
        if (_patientModelList == null) {
            List<Patient> patientList = new ArrayList<Patient>();
            for (int i = 0; i < 10; i++) {
                patientList.add(new Patient("Name_" + (i+1), i+1 + ""));
            }
            _patientModelList = new ListModelList(patientList);
        }
        return _patientModelList;
    }
    public String getPatientCode () {
        return _patientCode;
    }
    public void setPatientCode (String patientCode) {
        _patientCode = patientCode;
    }
}

Patient.java

package test;

public class Patient {
    private String _name;
    private String _code;
    public Patient (String name, String code) {
        _name = name;
        _code = code;
    }
    public String getName () {
        return _name;
    }
    public String getCode () {
        return _code;
    }
    public String getFormattedName () {
        return "Formatted " + getName();
    }
}

CustomComboitem.java

package test;

import org.zkoss.zul.Comboitem;

public class CustomComboitem extends Comboitem {
    private String _displayLabel;
    public CustomComboitem () {
        setWidgetOverride ("domLabel_", "function () {\n"
                + "         return zUtl.encodeXML(this._displayLabel || this.getLabel(), {pre: 1});\n"
                + "     }\n");
        setWidgetOverride ("setDisplayLabel", "function (v) {\n"
                + "         this._displayLabel = v;\n"
                + "     }\n");
    }
    public void setDisplayLabel (String displayLabel) {
        if (displayLabel == null) {
            displayLabel = "";
        }
        if (!displayLabel.equals(_displayLabel)) {
            _displayLabel = displayLabel;
            smartUpdate("displayLabel", _displayLabel);
        }
    }
    // override
    protected void renderProperties(org.zkoss.zk.ui.sys.ContentRenderer renderer)
        throws java.io.IOException {
        super.renderProperties(renderer);
        render(renderer, "displayLabel", _displayLabel);
    }
}
