gridview inside update panel:

<asp:updatepanel id="upmain" runat="server" updatemode="conditional">     <contenttemplate> ............... .............. </contenttemplate>  </asp:updatepanel>

when through rowcommand check fileuploader.hasfile , , shows false although has file.

i tried having postbacktrigger grid fileuploader.

but not of use.

how can deal problem?

please guide me.

have tried adding :

page.form.attributes.add("enctype", "multipart/form-data");

on page load

file upload not work partial post back. add line @ page load

scriptmanager.getcurrent(this).registerpostbackcontrol(this.yourgridviewid);

or use postbacktrigger.

<triggers>             <asp:postbacktrigger controlid="yourgridviewid" /> </triggers>

or need special asyncfileupload control defined in ajaxcontrol toolkit.

<ajaxtoolkit:asyncfileupload onclientuploaderror="uploaderror"      onclientuploadcomplete="uploadcomplete" runat="server"      id="asyncfileupload1" width="400px" uploaderstyle="modern"      uploadingbackcolor="#ccffff" throbberid="mythrobber" />
