Dynamic scrolling in a WPF application with ItemsControl object

In my xaml, I have some object made by me. I put them in row and, if the window is too little for all, I go in a new line.

The problem is when the window is so little that, also in a new line, the elements can't be all shown. The solution is simple: scroll bar!! But, if I set the Vertical/HorizontalScrollBarVisibility to auto, it doesn't go to a newline anymore.

This is my xaml:

<ScrollViewer CanContentScroll="True" VerticalScrollBarVisibility="Disabled" HorizontalScrollBarVisibility="Disabled" >
     <ItemsControl Name="ItemGroups" ItemsSource="{Binding NotifyItemUI}" />
</ScrollViewer>

and this is a screenshot what I need as my goal:

enter image description here

For example, if I resize my area vertically, and I have 3 rows of objects, in this way I can't see the third row if the window becames too little. In this case, I'd like to see a vertical scrollbar to scroll it.

Same thing horizontally: if I have too many elements for one single row, I have to scroll it horizontally.

What you describe looks like a WrapPanel, but the way you write about it suggests it is a custom control, so we cannot see what your ItemsControl is doing for layout.

However, ScrollViewer can have tricky interaction with a Panel. If the Panel measures to infinity, it will always consider itself big enough, and never tell the ScrollViewer it is out of room. The result is that the ScrollViewerdoes no know the scrollbar is needed. If this is your problem, then setting the Width and Height properties, or maxima as @Sheridan said, ought to fix it.
