Ext.net調用與選擇處理程序一DirectMethod在組合框中

內線標記Ext.net調用與選擇處理程序一DirectMethod在組合框中

<Listeners> 
    <Select Handler="Ext.net.DirectMethods.loadcombo2();" /> 
    </Listeners>

C＃

[DirectMethod] 
protected void loadcombo2() 
{ 
    this.ComboBox2.AddItem("List1", "L1"); 
    this.ComboBox2.AddItem("List2", "L2"); 

}

如何調用與組合框小區改變的直接方法？

即時得到一個錯誤這

Uncaught TypeError: Object #<Object> has no method 'loadcombo2'

嘗試設置公衆，而不是保護的loadcombo2

你可以試試這個代碼，它工作正常，我：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 

<script runat="server"> 
    protected void Page_Load(object sender, EventArgs e) 
    { 
     if (!X.IsAjaxRequest) { 
      this.Store1.DataSource = new object[] { 
       new object[] {"AL", "Alabama", "The Heart of Dixie"}, 

      }; 

      this.Store1.DataBind(); 
     } 

    } 

    [DirectMethod] 
    public void LoadCombo2() { 
     this.ComboBox1.AddItem("List1", "L1"); 
     this.ComboBox1.AddItem("List2", "L2"); 
    } 

</script> 

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

     <ext:Store ID="Store1" runat="server">

       <ext:ArrayReader> 
        <Fields> 
         <ext:RecordField Name="abbr" /> 
         <ext:RecordField Name="state" />

        </Fields> 
       </ext:ArrayReader> 
      </Reader>    
     </ext:Store> 

     <h2>Not Editable:</h2> 

     <ext:ComboBox 
      ID="ComboBox1" 
      runat="server"

      </Listeners> 

      </ext:ComboBox> 
    </form> 
</body> 
</html>

我認爲這裏的最佳做法是使用Select直接事件。

替換爲您現有的直接法：

protected void LoadCombo2(object sender, DirectEventArgs e) { 
    this.ComboBox1.AddItem("List1", "L1"); 
    this.ComboBox1.AddItem("List2", "L2"); 
}

，取而代之的監聽器：

<DirectEvents> 
    <Select OnEvent="LoadCombo2" /> 
</DirectEvents>
