一般我们使用这个treeview控件时都是在虚拟目录下复制webctrl_client目录到默认网站的根目录下,其实这对开发人员只是很简单的一个步骤,但是在打包部署的时候确碰到了问题,假设你的网站是安装在虚拟目录下,你怎么使你的安装程序自动复制这个目录到相应的地方去呢,这是个问题
.于是google,下载了
http://www.microsoft.com/china/MSDN/library/archives/library/DNAspp/html/aspnet-usingtreeviewieWebcontrol.asp里wencontrols的代码并安装,查看treeview.cs,终于找到主要是AddPathToFilename这个函数来控制目录得,而这个函数在BaseRichControl.cs的抽象类里定义
//
--------------------------------------------------------------------
//
Common Files
//
--------------------------------------------------------------------
/**/
/// <summary> /// Adds the common file path to the filename. /// </summary> /// <param name="filename">The filename to qualify with the common path.</param> /// <returns>The full path of the filename with the common path.</returns>
protected
string
AddPathToFilename(
string
filename)
{ return AddPathToFilename(Context, filename); }
/**/
/// <summary> /// Static version of AddPathToFilename so that classes not deriving from /// BaseRichControl can still find the common files path. /// </summary> /// <param name="context">The context from which to get the configuration.</param> /// <param name="filename">The filename to qualify with the common path.</param> /// <returns>The full path of the filename with the common path.</returns>
internal
static
string
AddPathToFilename(HttpContext context,
string
filename)
{ return FindCommonPath(context) + filename; }
/**/
/// <summary> /// Finds the path for client files used be server controls. /// </summary> /// <param name="context">The context from which to get the configuration.</param> /// <returns>The path name.</returns>
private
static
string
FindCommonPath(HttpContext context)
{ // Look at the current configuration for the path if (context != null) { NameValueCollection table = (NameValueCollection)context.GetConfig(ConfigName); if (table != null) { string path = (string)table[CommonFilesKey]; if (path != null) { return CleanupPath(path); } } } // Return the default path with version number Assembly assembly = typeof(BaseRichControl).Assembly; Version version = assembly.GetName().Version; return DefaultCommonFilesRoot + version.Major.ToString() + "_" + version.Minor.ToString() + "/"; }
,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
>
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
