答
尝试lbl.Caption += textbox.Text;
Abhinav建议的是一种服务器端方式，该方式需要回发才能生效.
我建议您继续使用Javascript.使用文本框onchange或onblurr事件.将它们附加到JS方法.在JS方法中，获取文本框的值并将其分配给所需的标签.
试试吧！
What Abhinav suggested is a server side way that would need a postback to take affect.
I would suggest you to go ahead with Javascript. Use textboxonchangeoronblurrevent. Attach them to a JS method. In the JS method, get the value of textbox and assign that to the desired label.
Try!
