VS 2013的用戶，可以透過 NuGet加入這個套件就能解決

myTextBox.Attributes.Add("onchange", "this.style.backgroundColor = 'yellow';");

TextBox1.Attributes.Add("OnClick", "this.value = '';");

SqlConnection conn = new SqlConnection(WebConfigurationManager.ConnectionStrings["schoolConnectionString"].ConnectionString);
conn.Open();

ViewState["prevUrl"] = Request.UrlReferrer.ToString();

假設我們的網址為http://demo.tc/Default3.aspx?id=1019&uu=77
