如题

这个是系统自带文档，按照这个步骤也不行呀

1. Internal Resources - All the images, javascript and xml can be streamed from inside
  the FreeTextBox.dll. In ASP.NET 2.0 these files are automatically pulled from
  the FreeTextBox.dll. In ASP.NET 1.x, you need to add the following httpHandler to web.config:

  <?xml version="1.0" encoding="utf-8" ?>
  <configuration>
  <system.web>
    <httpHandlers>
    <add verb="GET" path="FtbWebResource.axd" type="FreeTextBoxControls.AssemblyResourceHandler, FreeTextBox" />
    </httpHandlers>
  <system.web>
<configuration>

If you are attempting to use this method and having trouble, please view the source code of your page
and see where FtbWebResource.axd is being referenced. If it appears incorrect, please set
FreeTextBox.AssemblyResourceHandlerPath to the appropriate directory where you have set your web.config.


2. External Files - If you prefer not to use the internal JavaScript and image resources
  you can also have FreeTextBox link to external files which default to
  ~/aspnet_client/FreeTextBox/.
 
  To use this, you need to do the following:

  - Tell FreeTextBox which kind of files to look for external resources: JavaScriptLocation=ExternalFile, ToolbarImages=ExternalFile, ButtonImagesLocation=ExternalFile
  - Set the SupportFolder property of your FreeTextBox instance to the directory where you copied the files. For example, if your website is stored at www.mysite.com/FreeTextBoxFiles/, you should set SupportFolder="/FreeTextBoxFiles/".

  <FTB:FreeTextBox id="FreeTextBox1" SupportFolder="~/myfolder/FreeTextBox"
JavaScriptLocation="ExternalFile"
ToolbarImages="ExternalFile
ButtonImagesLocation="ExternalFile"
runat="server" />

Using FreeTextBox
*********************************************

To add FreeTextBox to an ASP.NET page, do the following:

1. Add the following line to the top of your page:

  <%@ Register TagPrefix="FTB" Namespace="FreeTextBoxControls" Assembly="FreeTextBox" %>

2. Add the following code between <form runat="server"> tags:

  <FTB:FreeTextBox id="FreeTextBox1" runat="Server" />
