WPF Visibility enumerations has three values : Visible, Hidden and Collapsed. I believe the link you posted is not correct.

The link above is for Silverlight, which is slightly different. The link that I believe you want is:http://msdn.microsoft.com/en-us/library/system.windows.visibility.aspx

It depends on how you define your grid. If you define your RowDefinitions to have a set height (either an actual number, or to "*"), then the row will have that height, regardless of the contents. If you set the height to Auto, it will size it to the contents.

I confirm, the link I posted is for Silverlight... I quickly googled it just to provide a link to the user... my intention was to point him towards the right direction...As @Wonko said, I guess there are other layout issues... Collapsed should ...collapse the item and "remove" the space that it occupies. If this is not happening, it means you set up the size to some fixed value somehow... Some code to look at would be great. We might provide a better hand...

Here is an example that shows what I mean in my last comment, based on clues from your question and comment. It shows how Visible, Hidden, and Collapsed work in a StackPanel, in a grid with fixed row heights, and in a grid with auto row heights.
This is pretty basic stuff, but hopefully it will help you, and any future Google searches.
