推荐答案

您不理解错误消息的哪一部分?很清楚.
您试图将类型为LiteralControl的对象转换为TextBox.
简单明了，您不能那样做.您可以从允许的LiteralControl文本值中设置TextBox文本值.
如果仍然不能解决问题，请发布导致您遇到困难的相关代码，以便我们进一步为您提供帮助.
干杯.

What part of the error message do you not understand? It is quite clear.
You are attempting to cast an object of type LiteralControl into a TextBox.
Plain and simple, you can''t do that. What you can do is set the TextBox text value from the LiteralControl text value which would be allowed.
If that doesn''t help, please post the relevant code which is causing you difficulty so that we can help you further.
Cheers.
