FileExplorer against UNC paths

I'd really like to use the File Explorer to allow user's to access and modify files in the home directory when they are off site. However, it appears that the File Explorer only allows you to view files and folders that are a part of your web application. Is it possible to get the File Explorer to access files outside of the web application and through a UNC path?

Radgrid enable/disable button column on child and/or parent

I have a radgrid control (with detail tables) on an aspx page . I have button column on the parent and the child(detail

tables) as well.

Based on some criteria I have to disable/enable the button column on parent and/or the child.
what is the best way to do it?

To explain further, the parent display the order and when click on the order it shows the order items for the order.
the button column is to duplicate an order. the button on the parent duplicates the whole order. the button on the child

(order items) duplicates an order with that particular order item.
Please advise the best solution,
Thanks

uploadprogess in listbox row?

hi,
i'm wanting to use the multiple file upload feature, but instead of the uploadprogress showing above the "input" button. I'd like to move it inside a listbox item row.

ideally if i added multiple files, i'd like to see each progress for each file show up in its own listbox row.

is this possible, and if so can someone give me some guidance?

thanks
