I have a div containing gridview and table, need to convert this div to an Image which will be sent in mail and printed. What are the best possible solutions for it.
// create the HTML to Image converter
HtmlToImage htmlToImageConverter = new HtmlToImage();
// set browser width
htmlToImageConverter.BrowserWidth = int.Parse(textBoxBrowserWidth.Text);
// set HTML Load timeout
htmlToImageConverter.HtmlLoadedTimeout = int.Parse(textBoxLoadHtmlTimeout.Text);
// set whether the resulted image is transparent
htmlToImageConverter.TransparentImage =
(dropDownListImageFormat.SelectedValue == "PNG") ?
checkBoxTransparentImage.Checked : false;
// set triggering mode
// for WaitTime mode set the wait time before convert
switch (dropDownListTriggeringMode.SelectedValue)
{
case "Auto":
htmlToImageConverter.TriggerMode = ConversionTriggerMode.Auto;
break;
case "WaitTime":
htmlToImageConverter.TriggerMode = ConversionTriggerMode.WaitTime;
htmlToImageConverter.WaitBeforeConvert = int.Parse(textBoxWaitTime.Text);
break;
case "Manual":
htmlToImageConverter.TriggerMode = ConversionTriggerMode.Manual;
break;
default:
htmlToImageConverter.TriggerMode = ConversionTriggerMode.Auto;
break;
}
// get the image buffer in the selected image format
byte[] imageBuffer = GetImageBuffer(imageObject);
// the image object rturned by converter can be disposed
imageObject.Dispose();
// inform the browser about the binary data format
string mimeType = imageFormatName == "jpg" ? "jpeg" : imageFormatName;
HttpContext.Current.Response.AddHeader("Content-Type", "image/" + mimeType);
// let the browser know how to open the image
HttpContext.Current.Response.AddHeader("Content-Disposition",
String.Format("attachment; filename={0};
size={1}",
imageFileName, imageBuffer.Length.ToString()));
// write the image buffer to HTTP response
HttpContext.Current.Response.BinaryWrite(imageBuffer);
// call End() method of HTTP response
// to stop ASP.NET page processing
HttpContext.Current.Response.End();
public void ConvertHtmlToImage()
{
Bitmap m_Bitmap = new Bitmap(400, 600);
PointF point = new PointF(0, 0);
SizeF maxSize = new System.Drawing.SizeF(500, 500);
HtmlRenderer.HtmlRender.Render(Graphics.FromImage(m_Bitmap),
"<html><body><p>This is a shitty html code</p>"
+ "<p>This is another html line</p></body>",
point, maxSize);
m_Bitmap.Save(@"C:\Test.png", ImageFormat.Png);
}

I think it is part of the iTextSharp library.

i would suggest you check out the link for details:
Convert HTML string to image [closed]
Codes as shown below:
public void ConvertHtmlToImage() { Bitmap m_Bitmap = new Bitmap(400, 600); PointF point = new PointF(0, 0); SizeF maxSize = new System.Drawing.SizeF(500, 500); HtmlRenderer.HtmlRender.Render(Graphics.FromImage(m_Bitmap), "<html><body><p>This is a shitty html code</p>" + "<p>This is another html line</p></body>", point, maxSize); m_Bitmap.Save(@"C:\Test.png", ImageFormat.Png); }Member

The best thing to do is to create html mail instead of taking image.
