WPF Scroll View Delema

I've created开发者_运维百科 a UserControl that contains a ScrollViewer panel that contains a data bounds ItemsControl. When I add this UserControl into a Grid's cell in the parent Window, the ScrollViewer expands to contain all of the items in the ItemsControl rather than constraining to the dimensions of the cell. Because of this, it won't scroll the items.

A little more code would be helpful to see exactly what you are doing...

One thing to check is the "HorizontalScrollBarVisibility" (or "VerticalScrollBarVisibility" depending on orientation) property of the ScrollViewer, it should default to "Auto", but in your user control this may be getting overridden at a higher level in the visual tree; try setting it explicitly:

<ScrollViewer VerticalScrollBarVisibility="Auto">

I figured it out. I had my layout a little bit messed up. Somehow I had a ListBox inside a ScrollView and so the two ScrollViewers messed each other up.

Sorry; WPF is very new to me. Still getting a feel for it.
