    Combobox in GridPanel show value when DoubleClick for Editing

    I have a problem with a ComboBox in a GridPanel.
    The Combobox is populated at in:

    protected void Page_Load(object sender, EventArgs e)
            this.ComboBox2.Items.Add(new Ext.Net.ListItem("Text1", "1"));
            this.ComboBox2.Items.Add(new Ext.Net.ListItem("Text2", "2"));
            this.ComboBox2.Items.Add(new Ext.Net.ListItem("Text3", "3"));
    In the GridPanel, in the aspx file, the comboBox is defined as:

    <ext:Column ID="Column4" runat="server" DataIndex="Profilo" Text="Profilo">
                            <Renderer Fn="nameRenderer"/>  
                                    <ext:ComboBox ID="ComboBox2" runat="server" DisplayField="Text" ValueField="Value">
                                            <ext:Store ID="Store2" runat="server">
                                                    <ext:Model ID="Model2" runat="server" IDProperty="Value">
                                                            <ext:ModelField Name="Text" />
                                                            <ext:ModelField Name="Value" />

    The render function named "nameRenderer" is defined as:

    var nameRenderer = function (value) {
                    var itemCombo = Ext.getCmp('ComboBox2');
                    var r = itemCombo.getStore();
                        if (this.columns[3].initialConfig.editor.field.mergeItems != null) {
                        var conto = this.columns[3];
                        var r = this.columns[3].initialConfig.editor.field.mergeItems;
                        for (i = 0; i < conto; i++) {
                            var valore = r[i][0];
                            var testo = r[i][1];
                            if (valore == value) {
                                return testo;
                    return value;

    The problem is when I DoubleClicking on the Combobox for editing because in the combox text I see the "value" of the Combobox and not the "text":
    EG: (in this sample I want to see "Text3" and not the value "3")
