如何申请CSS来ASP：FileUpload控件 [英] How to Apply CSS to ASP:FileUpload Control

问题描述

究竟是如何做到我这个风格控制？

How exactly do I style this control?

我也试过，但它不能正常工作。

I have tried this but it doesn't work.

<asp:FileUpload id="upload_tb" runat="server" />

#upload_tb
{
  width: 500px;
}

另外我怎么能风格，带有该控件的浏览按钮？如果它是不可能有其他的选择吗？

Also how can I style the browse button that comes with this control? If it is not possible are there other alternatives?

编辑：

我检查了生成的源代码和asp.net给出了控制这个ID ctl00_main_content_upload_tb

I checked the generated source and asp.net gives the control this id ctl00_main_content_upload_tb

我改变了的CSS

#ctl00_main_content_upload_tb
{
  width: 500px;
}

，但它不画出控制。它增加了填充的控制权。任何想法？

but it does not stretch the control. It adds padding to the right of the control. Any ideas?

推荐答案

您不能正式样式类型文件（*）（这是FileUpload控件呈现在页面上什么）的输入，但也有使用位方式使用Javascript和放大器; /或CSS - 见 http://www.quirksmode.org/dom/inputfile。 HTML 或 http://tiagoe.blogspot.com /2010/01/css-style-typefile-tags.html - 但它是不平凡的。

You can't officially style an input of type file (*) (which is what the FileUpload control renders on the page) but there are ways using a bit of Javascript &/or CSS - see http://www.quirksmode.org/dom/inputfile.html or http://tiagoe.blogspot.com/2010/01/css-style-typefile-tags.html - but it isn't trivial.

（*）这是一个安全措施

(*) It's a security measure
