ボタンのOnClickイベントには、次のコードは、私のASP.NETページです

Question

を発生しません：

<MdsMenu:MenuItem Text="Button" Href="#"> 
    <asp:Button ID="Button1" runat="server" Text="Button 01" OnClick="Button_Click" /> 
    <asp:Button ID="Button2" runat="server" Text="Button 02" OnClick="Button_Click" /> 
</MdsMenu:MenuItem> 

Button_Clickイベントは発生しませんなぜ私にはわかりません！

protected void Button_Click(object sender, EventArgs e) 
{ 
    Button senderButton = sender as Button; 
    Label1.Text = senderButton.ID.ToString(); 
} 

MdsMenu：MenuItemのは私のカスタムWebBrowserコントロールです。 MdsMenu：MenuItemタグからButtonコントロールを挿入するとうまくいきますが、MdsMenu：MenuItemタグ内に挿入しても関連するメソッドは起動しません。 私のコードで何が問題になっていますか？

ありがとうございました。

Answer 1

ステップ1：コントロールのの外側にある希望のOnClick の非表示ボタンが.aspxページ自体にあります。

<asp:Button ID="Button1" runat="server" OnClick="Button_Click" style="display: none;" /> 

ステップ＃2：このように、コントロール内のボタンにOnClientClickを持っている：

<asp:Button ID="SomeIdHere" runat="server" Text="Button 01" OnClientClick="return MakeRealClick('Button1');" /> 

「MakeRealClick」関数の引数として「本物」ボタンのIDを入れていることを確認してください。

ステップ＃3：ページにこのJavaScriptコードを持っている：

<script type="text/javascript"> 
    function MakeRealClick(sButtonID) { 
     var arrInputs = document.getElementsByTagName("input"); 
     for (var i = 0; i < arrInputs.length; i++) { 
      var oCurInput = arrInputs[i]; 
      if (oCurInput.type == "submit" && (oCurInput.id == sButtonID || EndsWith(oCurInput.id, "_" + sButtonID))) 
       oCurInput.click(); 
     } 
     return false; 
    } 

    function EndsWith(s1, s2) { 
     return (s1.length >= s2.length) && (s1.substr(s1.length - s2.length, s2.length) == s2); 
    } 
</script> 

これをクリックすると、メニュー内のボタンは、メニューの外にある他のボタンを探しますので、まだ本当の「持っていることが発生します"OnClickをクリックし、それを自動クリックすると、最終結果は隠しボタンをクリックした場合と同じになります。

確かに良い方法がありますが、私が言ったように：コードの変更を最小限に抑えた迅速な修正。
