cmd.Parameters.Add("@ID", SqlDbType.VarChar).Value = _id;

protected string UploadFile()

string filepath = "C:\\Uploads";
string uploadedfile = "";
if (docLogo.PostedFile != null)
{
try
{
docLogo.PostedFile.SaveAs(filepath + "\\" + docLogo.PostedFile.FileName);
Span1.InnerHtml = "Téléchargement effectué avec succès.";
uploadedfile = filepath + "\\" + docLogo.PostedFile.FileName;
return uploadedfile;
}
catch (Exception ex)
{
Span1.InnerHtml = "Error saving file <b>C:\\" + docLogo.Value + "</b><br>" + ex.ToString();
}
}
return uploadedfile;
} |
Lorsque j'essaie d'uploadé une image, il passe à null à la ligne: if (docLogo.PostedFile != null) dans ma fonction upload. Ici utilisé dans la fonction d'update, c'est le même effet dans la fonction d'ajout.
Le débug ne m'a rien donné de congruent et mes codes sont du quasi copier coller de la page suivante: https://msdn.microsoft.com/en-us/library/aa478971.aspx aussi si vous pouviez m'aider à résoudre ce problème, ce serait super :)
Bien à vous
