[Question] Property for limiting items to display

[Tenjim]

Hi guys,

Is it possible to have a property to limiting the number items you want to display ? I use that control to display several images and I want to have only two images display and the rest below and accessible by scrolling down.

Kinds Regards, Tenjim

Hi,

I don't understand what exactly you are trying to achieve. Could you give me more information on how the scenario you describe would look like.

Hi @sbaeumlisberger,

I use the VirtualizingWrapPanel with images as itemsource. I just want to know if there is a way to limit the number of object with a property (here images) to be displayed and not virtualized.

For example: I want to display only two images and scroll down to display the next two images from the itemsource.

Thank in advance, Tenjim

Hi Tenjim,

the items (in your case images) that fit into the viewport (the area visible in the UI) are always realized. For items not yet visible there are different caching settings. See here and here for some documentation. You can also have a look into the sample application, there you can try it out. If you have further questions about caching feel free to ask.

In you case it might be enough to limit the size of the control so that only two images fit into the viewport. The caching can also be disabled entirely.

If I misunderstand you and you want to achieve something else, let me know. In that case it would be helpful if you could provide a sample or mockup so that I can understand you scenario.
