update images(multiple Images) to database using file upload

Question

I have got 10 images with 10 file uploads on my update.aspx page. What I want to do is the client can change any current image to be replaced by new image using file upload. I can do that for a single file upload by using update button for each , but that will lead to 10 updateimage buttons , I want to acheive that by single update click which should check which fileupload images have been used and replace those with current image in the db.

Any help or suggestion will be appreciated.

You are going to want to handle the files using the HttpFileCollection class.

On the update button click event:

protected void Update_Click(object sender, EventArgs e)
{
   string filepath = "C:\\Uploads";

   //HttpFileCollection class initialization
   var filesToBeUploaded = Request.Files;

   for (int i = 0; i < filesToBeUploaded.Count; i++)
   {  
      //HttpPostedFile class initialization
      var postedFile = uploadedFiles[i];

      try
      {    
         if (postedFile.ContentLength > 0 )
         {    
            postedFile.SaveAs(filepath + "\\" + 
               System.IO.Path.GetFileName(postedFile.FileName));
         }    
      } 
      catch (Exception Ex)
      {    
         Label1.Text += "Error: <br/>" + Ex.Message;    
      }    
   }    
}

Mr A Over a year ago

but there are 10 file uploads, therefore i need 10 if, which will be a mess , is there any other wayof doing it

Govind Malviya Over a year ago

you can set name FileUpload1,FileUpload2,FileUpload3 and use FindControl in loop so u can achieve with single block

Mr A Over a year ago

u mean imgUpLoad = ((FileUpload)e.Item.FindControl("FileUpload1"));

Govind Malviya Over a year ago

yup.. and concat loop variable value with ID imgUpLoad = ((FileUpload)tbl1.FindControl("FileUpload"+i));

I think it is not a proper solution.
