我正在尝试使用来自代码隐藏的ID UserName的文本框中的值，但这不起作用：

UserName.Text

Answer 1

您可以使用[ID of the CreateUserWizard].UserName访问用户名。 CreateUserWizard控件公开用于访问输入到字段

中的值的属性

 string username = RegisterUser.UserName;
 string email = RegisterUser.Email;
 ... etc

您也可以从代码隐藏

设置它

 RegisterUser.UserName = "John Doe";

更新：如果您需要查找控件，请使用

TextBox usernameTextBox = RegisterUser.CreateUserStep.ContentTemplateContainer.FindControl("UserName") as TextBox;
string username = usernameTextBox.Text;

Answer 2

你可以使用这个：

TextBox UserName = (TextBox)"StepNameHere".FindControl("UserName");

您正在访问的控件当前未在您正在使用的事件上创建。我想这会有所帮助。

无法从代码隐藏中获取文本框值
