Downloading all the selected attachments

Question

Hi,

I have a gridview where in all the details regarding a product are listed out. The right most column of the grid is the attachment column where in the attachments are displayed if any. Currently, when the user clicks on this attachment the user is directed to 3rd party tool wherein this attachment details are visible.e.g if the document is attached and if the user clicks on it the user is navigated to this 3rd party tool where in the details of this document are displayed.

 

Now, my requirement is, I will add an ability for the user to select the attachments which user wishes to download. When a user clicks on the download button then all the attachments selected should be downloaded locally / or on the path provided.

 

Question is how can I achieve this? Is there any way for the same?

 

Can anyone please help me with this? 

 

Thanks in anticipation!
