Comparing JavaScript's style.display to .NET's visibility property

There are times when people claim that using JS .style.display = 'none'; is necessary, as opposed to using .NET .Visible = false.

What sets these two methods apart and why might one work with JS but not with .NET?

An example can be found at (last post on the page)

Appreciate any insights you can provide. Thanks!

Answer №1

  • opacity: 0 makes the element completely transparent, maintaining its dimensions, yet still present in the source code
  • Display = none eliminates the HTML element from the visible output on the webpage
  • Another solution is visibility: collapse, which conceals the element while preserving its layout space

Answer №2

The functionality of hiding elements in asp.net varies depending on the component being used. For most components, setting the controls' Visible property to false will completely prevent it from being rendered in the output stream. However, with certain custom components, the element may still be rendered but hidden using a style attribute. In the case mentioned, the ComponentArt control relies on a built-in control, so if you hide the built-in control, it could potentially affect the functioning of the ComponentArt control.

Answer №3

When you set Visible="false" for a control, it won't be displayed to the client at all. On the other hand, using style.display='none' will render the control but keep it hidden from view.
