I'm trying to upload files with the HtmlInputFile control, 
and I keep getting an "Object reference not set to an 
instance of an object." error, when calling 
UserFile.PostedFile.SaveAs()...code is as follows:


<INPUT id="UserFile" type="file" runat="server">

(and later...)

<input class="InputButton" id="btnUpload2" type="submit" 
value="Upload" runat="server">

In my codebehind, I have the following:

this.btnUpload2.ServerClick += new System.EventHandler
(this.btnUpload2_ServerClick);

private void btnUpload2_ServerClick(object sender, 
System.EventArgs e)
{
if(!ValidatePage())
	return;
string UploadPath = strServerPath + @"\Uploads\" + 
UserID.ToString() + @"\";
if(!Directory.Exists(UploadPath))
{
	Directory.CreateDirectory(UploadPath);
}
string strClPath = UserFile.Value;			
string strFileName = strClPath.Substring
((strClPath.LastIndexOf(@"\")+1));
UploadPath += strFileName;			
UserFile.PostedFile.SaveAs(UploadPath);		
}

Anyone have any suggestions?  Thanks...

Figured it out, needed the correct enctype in the <FORM> tag. :D
