示例1: Export

{
System.Drawing.Bitmap bitmap = null;
try
{
System.Drawing.Size size = grid.RangeToSize(rangeToExport);
bitmap = new System.Drawing.Bitmap(size.Width, size.Height);
using (System.Drawing.Graphics graphic = System.Drawing.Graphics.FromImage(bitmap))
{
Export(grid, graphic, rangeToExport, new System.Drawing.Point(0, 0));
}
}
catch (Exception)
{
if (bitmap != null)
{
bitmap.Dispose();
bitmap = null;
}

}
return bitmap;

public virtual void Export(GridVirtual grid, System.Drawing.Graphics graphics,
