sharepoint column default value settings not applied via content type

Problem:

Created Document library and associated custom content type with a site column containing default value. Say a numeric field with default value 1.

But when i upload document and select my custom content type, default value does not appear and is always blank.

Reason and solution:

Thanks to¬†SWEE CHING’s article, that i found the solution. Reason was that my custom content type was not set as default content type. If you want your default values to appead pre-selected, you have to set your custom content type as default.

Hope it will help someone!
