Hi Sachin,
If you want to include your own Web parts into MonoX module gallery, you need to place their DLLs into the main /bin folder. The ASCX files can go anywhere you like; there is a setting in web.config
<
add
key
=
"ModuleGalleryPath"
value
=
"/MonoX/ModuleGallery, /MonoX/Samples/WebPartSample"
/>
that defines where MonoX looks for its parts. You can add your own paths there.
