Can I display document versions in a paging grid

Question

I have a paging grid that will display a list of documents based on a entity_id 
 I need to be able to select a document within that grid and display the uploaded date and version number for each version. The file should also be available for download. Is there a way to do this?

Hello Jawara, 
 
I am not sure what do you mean with "entity_id" if it is a table like "student_id" then you will need to add a column named something like "documentId", then this way you can relate the document to your entity_id, if it is many to many, then add a many t many relationship. 
 
1) To get the list of version 
 You can use the plugin "Get Document Versions Metadata Information", you will get all the versions of a document, then just present the "List of Dictionaries" in a paging grid. 
* community.appian.com/.../get-document-version-metadata 
Specifically this part of the question was already answered 
* community.appian.com/.../how-to-get-all-document-version-from-selected-document

2) to create the paging grid with links you can refer to the documentation and recipes (when clicking to see more detail look at the recipies) 
* docs.appian.com/.../Paging_Grid_Component.html 
* docs.appian.com/.../recipe_use_links_in_a_grid_to_show_more_details_and_edit_data.html 
* Other quick way to see this is create a new interface and in the "design view" select the "Master -Detail " template. 
 
3) The file able to download is available i am not 100% this is the best solution, but i know you can create this link 
* https://{your_server}/suite/contents/GetContent.do?id=11111&version=28 
 
I hope this helps 
 
Best regards 
Jose

Hi Jawara J as per my understanding, if you want to deal with versions of a document, in such case you should go for implementing your own content management system in appian, where you can add , delete, update the document and their respective versions. 
 Where you can map your entityId and their respective entityTypeId with the document while uploading it into Appian through your implemented content management system. 
 And I believe it shouldn't be that difficult to build your own custom content management system, if time permits. 
 Hope this will help you.
