Hi. I have a code like that:
FileUpload img = (FileUpload)fuLogo;
byte[] logo;
if (img.HasFile && img.PostedFile != null)
{
HttpPostedFile File = fuLogo.PostedFile;
logo = new Byte[File.ContentLength];
File.InputStream.Read(logo, 0, File.ContentLength);
}
I send "logo" as an sp parameter. When i have no file to upload, i get a "parameter 'XXX', which was not supplied" error. So i say logo = null in the code but then it updates logo as null.
I don't want to update logo value when i don't select a new logo. What should i do?
Go to the complete details ...
