使用ContentEditable保存到DB与ASP.NET？

Question

我试图创建一个用户可以编辑文本的网页，当他们完成后，他们点击保存并输入的新文本保存到数据库中。

我没有在我的代码中发现任何错误，但由于某种原因，旧文本只是被重写入数据库而不是新文本。

这里是我的代码隐藏：

protected void saveBtn_Click(object sender, EventArgs e) 
{ 
    string newName; 
    string newIntro; 
    string newEduc; 
    string newWork; 

    h1New.Text = h1.Text; 

    newName = h1New.Text; 
    newIntro = intro.Text; 
    newEduc = educ.Text; 
    newWork = employ.Text; 

    string connectionInfo = ConfigurationManager.ConnectionStrings["ApplicationServices"].ConnectionString; 

    using (SqlConnection connection = new SqlConnection(connectionInfo)) 
    { 

     connection.Open(); 
     SqlCommand myCommand = new SqlCommand("UPDATE simpleContent SET userName = @newName, infoContent = @newIntro, educContent = @newEduc, workContent = @newWork WHERE userID = @userName", connection); 

     try 
     { 

      string username = HttpContext.Current.User.Identity.Name; 
      myCommand.Parameters.AddWithValue("@userName", username.ToString()); 
      myCommand.Parameters.AddWithValue("@newName", newName.ToString()); 
      myCommand.Parameters.AddWithValue("@newIntro", newIntro.ToString()); 
      myCommand.Parameters.AddWithValue("@newEduc", newEduc.ToString()); 
      myCommand.Parameters.AddWithValue("@newWork", newWork.ToString()); 
      myCommand.ExecuteNonQuery(); 
      connection.Close(); 
     } 
     catch 
     { 
      Response.Redirect("http://www.google.co.uk"); 
     } 


    } 
} 

我将不胜感激，你可能有任何指针。

尽量把你的格式代码：

protected void saveBtn_Click(object sender, EventArgs e) 
{  
// add variables 
    string connectionInfo = (...) 
    string commandText = (...) 

    using (...){ 
     SqlCommand myCommand = (...) 
     // add parameters 

    try 
    { 
     connection.Open(); 
     myCommand.ExecuteNonQuery(); 
     connection.Close(); 
    } 

    catch (Exception ex) 
      { 
       (...) 
      } 
}
