Coolite ComboBox数据绑定

　　　　<div>
        <ext:Store ID="Store1" runat="server" AutoLoad="true">
            <Reader>
                <ext:jsonreader readerid="employee_no">
                <%--<ext:ArrayReader>--%>
                    <Fields>
                        <ext:RecordField Name="employee_no">
                        </ext:RecordField>
                        <ext:RecordField Name="employee_display_name">
                        </ext:RecordField>
                    </Fields>
                    <%--</ext:ArrayReader>--%>
                </ext:JsonReader>
            </Reader>
        </ext:Store>
        <ext:ComboBox ID="ComboBox1" runat="server" StoreID="Store1" Width="250" Editable="false"
            TypeAhead="true" Mode="Local" ForceSelection="true" TriggerAction="All" SelectOnFocus="true"
            EmptyText="Please choose..." >
        </ext:ComboBox>
    </div>
    <ext:ScriptManager ID="ScriptManager1" runat="server">
    </ext:ScriptManager>

 CS代码：

            foreach (DataRow r in ds.Tables[0].Rows)
            {
                ComboBox1.Items.Add(new Coolite.Ext.Web.ListItem(r[1].ToString(), r[0].ToString()));
            }

用这种方式时，页面使用jsonreader或ArrayReader均可；

或者以下方式绑定：

  　　　　　 Store1.DataSource = ds.Tables[0];
            Store1.DataBind();
            ComboBox1.ValueField = "employee_no";
            ComboBox1.DisplayField = "employee_display_name";
            //ComboBox1.StoreID = Store1.ClientID;
             ComboBox1.DataBind();

 用这种方式时，页面使用jsonreader；StoreID 如果页面指定，则此处可不加ComboBox1.StoreID = Store1.ClientID;
