fileupload issue

Hi,

i'm using DNN 6.1.3, .net framework 4 and i have a problem with fileupload.
When i try to use fileupload control this don't get the filename selected.
here the simple HTML code:

<table>
<tr>
<td>
<asp:FileUpload ID="FileUpload1" runat="server" />
<asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</td>
</tr>
</table>

and here the codebehind:

protected void Button1_Click(object sender, EventArgs e) {
HttpPostedFile flname = FileUpload1.PostedFile;
Label1.Text = flname.FileName;
Label1.Text = FileUpload1.FileName;
}

the FileName property is always empty and if i try to use the property FileUpload1.HasFile it is always set to false.

Thanks for the help

Re: fileupload issue

That's a typical issue if you forget or don't realize that the asp:fileupload control requires a full postback for the upload to occur. If your "Button1" is wrapped in an AJAX update panel - either of your own creation or one that is applied by the DNN framework when a module control's "Supports Partial Rendering" option is enabled, only an AJAX callback will occur. The solution is to either not use an Update panel or to register Button1 as a postback control:

DotNetNuke.Framework.AJAX.RegisterPostBackControl(Button1);

Rather than creating your own file upload code, it would also be well to look into using either the DotNetNuke Url control or (my preference) the DotNetNuke.Web.UI.WebControls.DnnFilePicker control which will not only perform the upload but will properly add the file metadata to the DNN database tables.

Re: fileupload issue

William thank you very much for the solution!
i have no ajax function on my page and uncheck the support partial rendering on the page is enough.
