Hide entire datalist item based on a property

I have a datalist which is populated with values from a database. When the user clicks a checkbox, I want to loop through all of the datalist items and hide all of the items that have the property isActive = false (which is displayed as “Disabled” in a text label). The item template consists of a table that contains multiple other items, buttons etc, which have not been included below. I therefore want to hide all elements that are found under the itemtemplate of a specific item.

Uploading large video file

I would like to build a webpage(simple form) where users can submit media files, most likely video files.
The video files will be anywhere from 100mb – 500mb(or possibly more, depending on the file compression)
I was wondering if you could recommend any hosting plan(or company) that may fit my requirement.
