Check the Content type before saving the file to a particular location using

FileUpload1.PostedFile.ContentType

ishamputra,

String ext=System.IO.Path.GetExtension(FileUpload1.FileName).ToUpper();

if(ext==".TXT") 
  {
    String content=System.Text.Encoding.ASCII.GetString(FileUpload1.FileBytes)
    String []ar=content.Split(';');
    GridView1.DataSource=ar;
    GridView1.DataBind();
  }
