1 建立一个Store

Dim objStore As New Ext.Net.Store
Dim objModel As New Ext.Net.Model

objModel.Fields.Add("myID")
objModel.Fields.Add("myName")
objStore.Model.Add(objModel)

2 给Store 设立数据源

Dim objList As New List(Of MyClass1)
Dim objClass1 As New MyClass1
Dim objClass2 As New MyClass1

objClass1.myID = "jimmyID"
objClass1.myName = "jimmyName"
objClass2.myID = "hardenID"
objClass2.myName = "hardenName"

objList.Add(objClass1)
objList.Add(objClass2)

objStore.DataSource = objList
If (Not Ext.Net.X.IsAjaxRequest) Then
objStore.DataBind()
End If

3 将相应的store 绑定到comboBox

Dim objComboBox As New Ext.Net.ComboBox

objComboBox.Store.add(objStore)

注释： 前两步还可以设置为GridPanel的数据源，只是在第三步绑定有些许的改变而已。比如改为 objGridPanel.store.add( objStore)
