推荐答案

您的意思是Textbox.text为空白吗?

如果您使用asp.net文本框，则在将表单回发到服务器时(例如，单击提交按钮时)，该值将可用.

What do you mean Textbox.text is blank?

If you use an asp.net textbox the value will be available when the form is posted-back tot he server, such as when a submit button is clicked.

看看本文:
Web应用程序的ClientCallback自定义控件 [

Have a look at this article:
ClientCallback custom control for web applications[^]
This passes the nodeID to Stored Proc and get backs data.

You have to access the textbox in your Javascript. Associate any event like, onchange or onblur to the callback and in the javascript method, use the value to pass on to server side to get data.
