ext.net combobox 的初始化

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)
