How to use VirtualizingWrapPanel where the items in the panel are of different sizes

[Rajani]

Hi,

I want to use the VirtualizingWrapPanel for a thumbnail view (similar to the File explorer view) that I'm building. However the thumbnails that the panel holds will not all be of the same size. Now the problem I'm facing is that the VirtualizingWrapPanel requires me to specify the ItemWidth. I cannot provide the ItemWidth because the width of the thumbnails are not always the same.. Is there any way to provide something similar to "auto" for ItemWidth? Any suggestions?

Currently I'm using the WPF VirtualizingStackPanel and it seems to work great but I'm wasting a lot of UI space and therefore want to use VirtualizingWrapPanel instead.

Thank you,
Rajani.

Hi Rajani,

Unfortunately the VirtualizingWrapPanel is designed to show equal sized items only. May I ask what exactly are you trying to achieve so we can suggest an alternative solution or suggest a viable workaround?

Hope to hear from you soon!

I have this same problem. I'm trying to duplicate the "List" view from File Explorer. In that situation, all items have the same height but the widths are different depending on the file name. This means when oriented to grow horizontally that the number of "columns" should be known and a horizontal scrollbar should be viable. However, the user would not accept truncated file names in the view, nor do I know of a way to get the maximum visual width of any item to dynamically increase the common item width of the VirtualizingWrapPanel.

Hello,

I am afraid that our VirtualizingWrapPanel does not support items of different size. It is designed to show equal sized items only. Unfortunately, I can not suggest you an alternative control from our WPF suite.
