Question

我正在使用ASP.NET Web应用程序，我有一个注册表单，每当我尝试键入用户Username时，此错误都会显示在浏览器中！

无效的回发或回调参数。事件验证已启用在配置中使用或＆lt;％@ Page EnableEventValidation =“true”％＆gt;在一个页面中。为了安全目的，此功能验证回发或回调的参数事件源自最初呈现的服务器控件他们。如果数据有效且预期，请使用 ClientScriptManager.RegisterForEventValidation方法注册回发或回调数据以进行验证。

我试图在if(!IsPostBack){///Your Code.... }中添加Page_Load，但它无效！我再次在EnableEventValidation="false"中尝试了web.config它没有用！请帮忙吗？

注册表格代码：

protected void Button6_Click(object sender, EventArgs e)
{
    try
    {
        SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["MyDatabase"].ConnectionString);
        conn.Open();
        string insertQuery = "insert into Users (Username,Password,Email) values (@username, @password, @email)";
        SqlCommand com = new SqlCommand(insertQuery, conn);

        com.Parameters.AddWithValue("@username", TextBoxUsername.Text);
        com.Parameters.AddWithValue("@password", TextBoxPassword.Text);
        com.Parameters.AddWithValue("@email", TextBoxEmail.Text);

        com.ExecuteNonQuery();
        conn.Close();
        Response.Redirect("Seller_Registration.aspx");
    }
    catch (Exception ex)
    { Response.Write("error"); }
}

和我的web.config代码：

<pages validateRequest="true">
        <namespaces>
        <add namespace="System.Web.Optimization" />
        <add namespace="Microsoft.AspNet.Identity" />
      </namespaces>
      <controls>
        <add assembly="Microsoft.AspNet.Web.Optimization.WebForms" namespace="Microsoft.AspNet.Web.Optimization.WebForms" tagPrefix="webopt" />
      </controls>
    </pages>
