How to make WPF wrappanel child items to stretch?

Use a UniformGrid rather than a WrapPanel . Just set the number of columns you want with the Columns property, and it should give you the desired result.

I'd like to create an ItemsControl where child items are placed like a WrapPanel, but child Items should take as much space as it can. So that when the window size gets larger or smaller, the child items should stretch according to a certain width:height ratio. When the child items get added or removed from the ItemsControl's ItemsSource, the WrapPanel should place linebreaks among items appropriately to keep child item's width:height ratio.

Below is what I have so far. Is it possible to do this in Xaml? Or should I create a custom control for this?

Thanks in advance! Wpf xaml custom-controls itemscontrol wrappanel link|improve this question edited Nov 16 '11 at 0:24 asked Nov 4 '11 at 4:48Daniel748415 91% accept rate.

Does unlimited vertical orientation UniformGrid serve your purpose... social.msdn.microsoft.com/Forums/en-US/w... – AngelWPF Nov 4 '11 at 6:08 I think it's somewhat different from what I need, but thanks! – Daniel Nov 4 '11 at 6:34 Wrap and stack panels intentionally take up as little space as possible. As far as I've seen you can't override that behavior, so you must use a different type of grouping control.

Have you tried the HorizontalContentAlignment="Stretch" property in the itemscontrol.

Yes, but it doesn't work. Thanks for suggesting – Daniel Nov 5 '11 at 10:07 Can you post the whole code in DataTemplate. – Tan Nov 7 '11 at 16:14 I've posted the whole code in DataTemplate, thanks – Daniel Nov 16 '11 at 0:35 as I can see HorizontalContentAlignment="Stretch" would work.

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.
