按钮拒绝工作

Question

我有一个标准的按钮应该调用一个方法，但它只是拒绝工作，我不明白为什么。

ASP代码：

<asp:FileUpload ID="FileUpload1" runat="server" /> 
     <asp:Button 
      ID="UploadButton" runat="server" onclick="UploadButton_Click" Text="Change Logo" /> 

后面的代码：

protected void UploadButton_Click(object sender, EventArgs e) 
     { 
      PasswordLabel.Visible = true; 
      PasswordLabel.Text = "TEST Before"; 
      Image_Inserting(this); 
      PasswordLabel.Text = "TEST After"; 

     } 

我刚添加的文本框方法来测试它，但它似乎并没有被回发（甚至当我删除I​​mage_Inserting通话）。所有其他按钮都可以正常工作，所以我不知道为什么这个按钮不起作用。

Answer 1

我的猜测是，它是造成其他（可能是隐藏的）验证运行。请务必设置原因验证至虚假。

Answer 2

报价整体PAGE-按钮代码： *我刚添加的文本框方法*

我想我们试图更新密码的textBox你不能。

只有：

PasswordLabel .Attributes["value"] = "aaa";
