Question

我有一个标准按钮，应该调用一个方法，但它只是拒绝工作，我无法弄清楚原因。

ASP代码：

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

代码背后：

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

        }

我刚刚添加了文本框方法来测试它，但它似乎没有回发（即使我删除了Image_Inserting调用）。所有其他按钮工作正常，所以我不知道为什么这个按钮不起作用。

我想我们试图更新你不能的密码文本框。

仅限于：

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

按钮拒绝工作
