,本来开始的想法是改这个函数,后来发现其实它还有个可配置的路径接口,还是先配置吧!
于是在web.config加入以下节
<configSections>
<section name="MicrosoftWebControls" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
</configSections>
<MicrosoftWebControls>
<add key="CommonFiles" value="/web/treepath/"></add>
</MicrosoftWebControls>
<section name="MicrosoftWebControls" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
</configSections>
<MicrosoftWebControls>
<add key="CommonFiles" value="/web/treepath/"></add>
</MicrosoftWebControls>
注意:configSections一定要放在第一个子节最前面.
剪切默认网站的webctrl_client目录到虚拟目录web/treepath/下,运行程序,树型界面出现了,只是前面的加减号出现问题,再右键查看WEB代码,发现SystemImagesPath属性还是指到webctrl_client目录下,看了SystemImagesPath的代码,把treeview控件的SystemImagesPath设置为空,再次运行程序,OK!全部通过,treeview的图片目录再也不需要依赖默认网站的图片目录了,打包也变的方便了,如果是几个网站在一个机器上,你也可以设置自己独立的treeview图片风格了,嘿嘿,再此写下这些供大家参考
