Put this code to the Image where you want to render and apply as source

var writeableBitmap = new WriteableBitmap((int)YourLongListSelector.RenderSize.Width, (int)LongListSelector.RenderSize.Height); writeableBitmap.Render(YourLongListSelector, new ScaleTransform() { ScaleX = 1, ScaleY = 1 }); writeableBitmap.Invalidate(); image.Source = writeableBitmap;

This work fine if the longlistselector is totally visible, but fail when if there are some elements those not are visible. UI Elements are not in visual tree wont be set in the image =(

@Lu1zZz Is not it helpful? why do you want to make it invisible?

yeah, this is so helpful, I mean "not visible" when the longlistselector have scrollview elements , do you know how can include them in writeableBitmap?
