下面的代码用于控件的下拉列表属性页
public class storedprocedurenameconverter
inherits stringconverter 存储过程 有兴趣可以添加你自己的存储过程 要用下拉列表编辑属性 
public overrides function getstandardvaluessupported(byval context as itypedescriptorcontext) as boolean
return true
end function 这个override返回下拉列表项。 public overrides function getstandardvalues(byval context as itypedescriptorcontext) as standardvaluescollection dim stringarray as arraylist = new arraylist() stringarray.add("sys_quicksortpaging") stringarray.add("sys_sortdatapager") return new standardvaluescollection(stringarray) end function return true的话只能选，return flase可选可填 public overrides function getstandardvaluesexclusive(byval context as itypedescriptorcontext) as boolean return true end function
end class
public class controltodatabindconverter inherits stringconverter 列出可以绑定的控件 要用下拉列表编辑属性 public overrides function getstandardvaluessupported(byval context as itypedescriptorcontext) as boolean return true end function 这个override返回下拉列表项。 public overrides function getstandardvalues(byval context as itypedescriptorcontext) as standardvaluescollection dim stringarray as arraylist = new arraylist() dim i as long dim objcontrol as controlcollection objcontrol = ctype(context.container.components(0), page).controls for i = 0 to objcontrol.count - 1 if typeof objcontrol(i) is gridview or typeof objcontrol(i) is datalist then stringarray.add(objcontrol(i).clientid) end if next return new standardvaluescollection(stringarray) end function return true的话只能选，return false可选可填 public overrides function getstandardvaluesexclusive(byval context as itypedescriptorcontext) as boolean return false end function end class文章整理：西部数码--专业提供域名注册、虚拟主机服务
