                obj.Do_Transaction(sql_insert);
                ScriptManager.RegisterStartupScript(this, this.GetType(), "key", "alert(' Order done Successfully')", true);

推荐答案

如果你能够访问标签的内容，那么你的名字可能有问题文本框而不是TxtQuantity，它可能是txtQuantity

if u r able to access the content of the label, then there could be problem in the name of ur textbox like Instead of "TxtQuantity" , it could be "txtQuantity"
