asp.net C# Fileupload always returns false
I am working with a fileuploader to upload a picture. However, evertyime i select the file and click the upload button it says that the fileuploader.file returns a value of false and does not run the next lines of code. All i can find is that it has to be in in a seperate form and that the method has to be "post", but that did not fix the problem.
here is my codebehind.
if (FileUploadControl.HasFile)
{
try
{
string filename = Path.GetFileName(FileUploadControl.FileName);
FileUploadControl.SaveAs(Server.MapPath("~/") + filename);

}
catch (Exception ex)
{
StatusLabel.Text = "Upload status: The file could not be uploaded. The following error occured: " + ex.Message;
}
}
here is my front end code.
<form id="form2" action="CompProfile.aspx" method="post" enctype="multipart/form-data">
<asp:FileUpload id="FileUploadControl" runat="server" />
<asp:Button runat="server" id="UploadButton" text="Upload" onclick="UploadButton_Click" />
<asp:Label runat="server" id="StatusLabel" text="Upload status: " />
</form>
If you are testing with a 0 byte sized file it will return false. Make sure the file actually isn't empty.
Your form should have runat="server"
instead of method="post"
and action="..."
