Commented Unassigned: Copy image of Xceed DataGridControl to bitmap [21900]

I'm using Xceed WPF Toolkit (Community Edition) DataGridControl, and I would like to create a bitmap from the control (either to put on the clipboard or save to a png).

I have tried using a RenderBitmapTarget, but it will only copy the control as it is rendered on the screen (my grid is bigger than the screen).

My RenderBitmapTarget code looks like this:

```
RenderTargetBitmap rtb = new RenderTargetBitmap((int)control.ActualWidth, (int)control.ActualHeight, 96, 96, PixelFormats.Pbgra32);
rtb.Render(control);
PngBitmapEncoder png = new PngBitmapEncoder();
png.Frames.Add(BitmapFrame.Create(rtb));
MemoryStream stream = new MemoryStream();
png.Save(stream);
Image image = Image.FromStream(stream);
```

I've tried specifying a larger size (both in the RenderTargetBitmap constructor, and specifying new width/height for the control, but both just yielded the same image on a larger canvas.

Any thoughts?

By using the following code:

tempWidth = myControl.ActualWidth;
tempHeight = myControl.ActualHeight;

myControl.Width = double.NaN;
myControl.Height = double.NaN;

myControl.UpdateLayout();

RenderTargetBitmap rtb = new RenderTargetBitmap((int)myControl.ActualWidth, (int)myControl.ActualHeight, 96, 96, PixelFormats.Pbgra32);

rtb.Render(myControl);

PngBitmapEncoder pbe = new PngBitmapEncoder();
pbe.Frames.Add(BitmapFrame.Create(rtb));
MemoryStream stream = new MemoryStream();
pbe.Save(stream);
image = (System.Drawing.Bitmap)System.Drawing.Image.FromStream(stream);

CEGrid.Width = tempWidth;
CEGrid.Height = tempHeight;

I get the control rendered at the correct size, but the cells that were off the screen are blank. How do it get it to update those cells?
