Control image Export in Winform

In WinForm, to export the display of a control as a bitmap image, you can do this in two ways:

1. Using the DrawToBitmap method of the control itself

Newnew  Bitmap (Chartcontainpanel.width, chartcontainpanel.height); Chartcontainpanel.drawtobitmap (map, chartcontainpanel.clientrectangle); map. Save (fileName);

Note that DrawToBitmap is the display of the control is redrawn, if the control itself is displayed by the content is not loaded through the paint event, but by other means of drawing up, the content will be blank

2. Using the Graphics function CopyFromScreen

New==new== Chartcontainpanel.pointtoscreen (This 0 0 , s); Memoryimage.save (fileName);  

This approach is done directly to the screen
