I tried to search for the problem in the internet and I see everyone is asking about the problem for FileUpload control inside the UpdatePanel. First of all, I am not using an UpdatePanel. Below is my code:
HTML
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" method="post" runat="server" enctype="multipart/form-data">
<div>
<asp:FileUpload ID="fuImport" runat="server" />
<asp:Button ID="btnImport" runat="server" Text="Import" />
</div>
</form>
</body>
</html>
Code Behind
Protected Sub btnImport_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnImport.Click
If (fuImport.HasFile) Then
fuImport.SaveAs(My.Settings.FileImportPath & Path.GetFileName(fuImport.FileName))
End If
End Sub
I see that fuImport.HasFile is False, but fuImport.FileName gives just the file name. For e.g., if I choose c:\1.txt, it gives just "1.txt".
Can anybody let me know why fuImport.HasFile is False though I have chosen a file?
I found the answer. The txt file I was uploading was empty. I edited the text file and then saved by typing something in it. I could not find this anywhere mentioned in the msdn or I am not sure whether I was looking at a wrong place. The suggestion by Kasys in this post helped me.
