Why does WrapPanel wrap TextBlocks horizontally but UserControls vertically?

In your second sample, try to use the WrapPanel inside a ItemsPanelTemplate for the ItemsControl, otherwise the ItemsControl uses a StackPanel by default and your WrapPanel doesn't do anything as there is nothing to wrap.

This is happening because the ItemsControl, by default uses a StackPanel in vertical orientation to layout it child objects. So the wrap panel is actually only laying out one child which is the ItemsControl. What you wan't to do is set the ItemsControl's ItemsPanel property so that is uses a WrapPanel for layout.

Your code would look like this.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
