How to save a screenshot of a WPF control?

What you want is to save an image from a single UIElementand you can do that using the RenderTargetBitmap.RenderMethod. This method takes a Visualinput parameter and luckily, that is one of the base classes for all UIElements. So assuming that you want to save a .png file, you could do this:

A simpler approach (if you can apply the word “simpler” to anything dealing with WPF and rendering) is to create a VisualBrush that contains an image of the control. Then you can fill the target bitmap with that brush so it displays the control’s image. This example takes that approach.

How would I create borderless full screen applications with WPF? Is that possible with Navigation Applications as well? the way i had to do it is to use win32 interop to create a layered window which takes up the whole screen, then make that window topmost.

One is to move the control to its parent’s origin, render its image, and then move the control back. A simpler approach (if you can apply the word “simpler” to anything dealing with WPF and rendering) is to create a VisualBrush that contains an image of the control.

The code example in this article shows how to view, stretch, rotate, and manipulate images in a WPF app using C#. 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.

Call the static Create method of the File class with the path to the output file as argument. This will create a FileStream … to which the encoded image data will be written. Create a JpegBitmapEncoder or PngBitmapEncoder.

This topic explains how to use the WPF build-in functionality to export a visual or a visual-derived object to a PNG or JPEG image. Because the code example in this topic uses xamDataChart™ you need to have basic knowledge of this control.

I want to take a screenshot of the entire desktop (i.e. all monitors) and save it as a .jpg to a specific folder with the time and date as the file name when I click the screenshot button. I was able to achieve this in my Windows Forms application, but haven’t been able to do so with my WPF application.

Also, a simple code that will allow you to draw a WPF Rectangle by MouseDown & MouseMove method, will be greatly appreciated. To capture the screen in a bimap you can do this:

In Windows Vista and later, the appearance of the non-client areas of application windows (the title bar, icon, window border, and caption buttons) is controlled by the DWM. Using the DWM APIs, you can change the way the DWM renders a window’s frame. One feature of the DWM APIs is the ability to extend the application frame into the client area.
