Hi,
It probably has something to do with my updatepanel.
- <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<cc2:Uploader ID="uplAttach" runat="server" TempDirectory="~/Library/temp_upload"
MaxFilesLimit="5" FileTooLargeMsg="Bestand is te groot! Max. 10 MB." MultipleFilesUpload="true"
ShowProgressInfo="true" ShowProgressBar="false" InsertText="Kies uw bijlagen"
MaxFilesLimitMsg="U mag maximaal 5 bijlagen uploaden">
<ValidateOption MaxSizeKB="10000" AllowedFileExtensions="pdf,doc,docx,zip,rar" />
</cc2:Uploader>
</ContentTemplate>
</asp:UpdatePanel>
But if I do not place the uploader in an uploadpanel, the complete page will postback and my info will still dissappear.
