Here, we have a custom tree view web part for SharePoint 2010 document libraries which is having the option to select the views in custom properties. Here we have only two views, one is for show only folder structure(will not show any files over there in that folder) and user based filtration of the document library(Only shows the folders or files which is created by the currently logged user). These above two custom properties can be set by the admin by checking the "Only Folder Structures" and "Related Login User" check boxes and the document library name can be put over there in the "Document Library Name" section in Custom settings of web part property window. Below images are showing the exact structure of the tree view with property section. This is a thoroughly tested and its working fine for my project.
Created Platform: Visual studio 2010, Sharepoint 2010 Foundation/Standard/Enterprise Versions.
Note:This is created based on the code from some other sites, but i have modified the codes as per my requirement.
