how would I incorporate print to print the WriteableBitmap? and setting the image to fit a single page?

I can't implicitly convert a WriteableBitmap to a System.Windows.UIElement

Is it possible to do something like this?

private void Button_Click_Print(object sender, RoutedEventArgs e)
{
WriteableBitmap writablebmp = new WriteableBitmap(gridContainer, null);

writablebmp.Invalidate();

int width = (int)this.gridContainer.ActualWidth;
int height = (int)this.gridContainer.ActualHeight;

PrintDocument dlChart = new PrintDocument();

dlChart.PrintPage += (s, args) =>
{
args.PageVisual = writablebmp;

};
dlChart.Print("Chart");

}

I tried the same as of Sample in my project but i am getting some errors:

1. i can't found  System.Drawing under reference, in order to add it

2. getting error for      RenderTargetBitmap

3. getting error for      PixelFormats

4. getting error for      FormatConvertedBitmap

5. getting error for      BmpBitmapEncoder

6. getting error for      BitmapFrame

7. getting error for      PointF

8.getting error for       Process

Can you help me to solve the same.Thanks in advance.

I am using Infragistic v12.1 and SL5
