I've created a WPF application which has a Canvas on which I place UserControls which are moveable and resizeable by the user (just like a Windows-Window). Now I have detected that this can be very slow on older PC's which is a problem.
As a solution I thought about generating a graphic showing the UserControl and show this while resizing/dragging the Control, to prevent WPF from recalculating all Elements permanently. The only problem is that I have no idea how to generate this image.
Is there perhaps something like a function which does this in .Net? Or how could I do this on my own?

The Image class in C# represents an image control in WPF that is used to load and display an image. The Image control displays .bmp, .gif, .ico, .jpg, .png, .wdp and .tiff files. If a file is a multiframe image, only the first frame is displayed.

You can render a WPF control to a bitmap using RenderTargetBitmap, then this image can be copied to the clipboard, saved to a file, or used as part of your GUI Beware with this that you can hit problems when parts of the control you are trying to render are not visible (within a scroll viewer perhaps)
To do this, you must create a dependency property in the code behind of your control and in the xaml file of your control you must assign a binding from image's Source property to your control Source property. <!-- Set a name for your control. We need to refer it.
Click on the Browse button to browse the files and the selected file will be displayed in the Viewer. Figure 2. How to view an Image in WPF? The Image element in XAML represents a WPF Image control and is used to display images in WPF.
