设置多个值组合框

我与多选选项的组合框，我想从代码隐藏设置的倍数值，这里是我的商店：设置多个值组合框

<ext:Store ID="StoreT" runat="server" PageSize="10"> 
     <Model> 
      <ext:Model ID="Model3" runat="server"> 
       <Fields> 
        <ext:ModelField Name="name" /> 
        <ext:ModelField Name="code" /> 
       </Fields> 
      </ext:Model> 
     </Model> 
</ext:Store> 

<ext:ComboBox ID="ComboBoxT" MultiSelect="true" StoreID="StoreT" DisplayField="name" ValueField="code"> 
</ext:ComboBox>

我想传递给setValues方法多码的选择与此同时。

请使用ComboBox的SelectedItems。

<%@ Page Language="C#" %> 

<script runat="server"> 
    protected void Page_Load(object sender, EventArgs e) 
    { 
     if (!X.IsAjaxRequest) 
     { 
      Store store = this.ComboBox1.GetStore(); 
      store.DataSource = new object[] 
      { 
       new object[] { "1", "Item 1" }, 
       new object[] { "2", "Item 2" }, 
       new object[] { "3", "Item 3" }, 
       new object[] { "4", "Item 4" } 
      }; 
     } 
    } 

    protected void SetValues(object sender, DirectEventArgs e) 
    { 
     this.ComboBox1.SelectedItems.Clear(); 
     this.ComboBox1.SelectedItems.Add(new Ext.Net.ListItem { Value = "2" }); 
     this.ComboBox1.SelectedItems.Add(new Ext.Net.ListItem { Value = "4" }); 
     this.ComboBox1.UpdateSelectedItems(); 
    } 
</script> 

<!DOCTYPE html> 

<html> 
<head runat="server"> 
    <title>Ext.NET v2 Example</title> 
</head> 
<body> 
    <form runat="server"> 
     <ext:ResourceManager runat="server" /> 

     <ext:Button runat="server" Text="Set 2 and 4" OnDirectClick="SetValues" /> 

     <ext:ComboBox 
      ID="ComboBox1" 
      runat="server" 
      DisplayField="text" 
      ValueField="value" 
      MultiSelect="true"> 
      <Store> 
       <ext:Store runat="server"> 
        <Model> 
         <ext:Model runat="server"> 
          <Fields> 
           <ext:ModelField Name="value" /> 
           <ext:ModelField Name="text" /> 
          </Fields> 
         </ext:Model> 
        </Model> 
        <Reader> 
         <ext:ArrayReader /> 
        </Reader> 
       </ext:Store> 
      </Store> 
      <SelectedItems> 
       <ext:ListItem Value="1" /> 
       <ext:ListItem Value="3" /> 
      </SelectedItems> 
     </ext:ComboBox> 
    </form> 
</body> 
</html>
