Solution 1

Use fileuploader(asp.net) to upload a file
below is the code to validate only .pptx file
 
if (FileUpload1.HasFile)
        {
                string strFileExtension = Path.GetExtension(FileUpload1.PostedFile.FileName);
                if (strFileExtension != null)
                {
                    string validFileExtension = strFileExtension.ToLower();
                    if (validFileExtension == ".pptx")
                    {
                            string filepath = Server.MapPath("~/Images");
                            if (!Directory.Exists(filepath ))
                            {
                                Directory.CreateDirectory(imagePath);
                            }
                            string fileName = Guid.NewGuid().ToString().Replace("-", "") + strFileExtension; //to generate unique file name
                           FileUpload1.SaveAs(filepath  + "/" + fileName);
 
                    }
                    else
                    {
                        lblMessage.Text = "upload only pptx file";
                        return;
                    }
              }
    }

Hi, im sorry but I wanted to ask, why did you use the "UploadIcon" in the IF statement? By the way, here are the following information that I believe would contribute:
 
ID: FileUpload1
Database Data Type: varbinary(MAX)
 
The FileUpload will only accept pptx file, and when uploaded, it must appear in the GridView1.
 
Thank you Azziet, I appreciate your help :)
Thanks for the upcoming answers! Thanks alot!
