-1 Thanks I displayed image sucessfully
-1 PostedFile.SaveAs(strFilename) takes physical path whereas Image2.ImageUrl accepts virtual path.
Try the following code.
String filename = FileUpload1.PostedFile.FileName;
string strFilename = Server.MapPath("Sample") + "\\" + filename;
FileUpload1.PostedFile.SaveAs(strFilename);
//Show Image
Image2.ImageUrl= "~/Sample/" + filename ;
// Here I am asuming that 'Sample' folder is directly under the application root. Otherwise change the path accordingly.
