What problems are you having with it? I politely ask you to be more specific.

 

by: mathieu_cuprykPosted on 2009-11-04 at 06:25:49ID: 25739531

It does not work with rad. Meaning When I change from up tab to another It just does not work.

I'm still not sure what you mean, but I notice that your CustomValidators are lacking the "ControlToValidate" attribute.

<asp:CustomValidator ID="valFileSize" runat="server" ErrorMessage="The image exceeds 1 MB" ControlToUpdate="FileUpload1" OnServerValidate="valFileSize_ServerValidate" Display="Dynamic" />
<asp:CustomValidator ID="valFile" runat="server" ErrorMessage="No file uploaded" ControlToUpdate="FileUpload1"  OnServerValidate="valFile_ServerValidate" Display="Dynamic" />
<asp:CustomValidator ID="valFileType" runat="server" ErrorMessage="This isn't not an image"  ControlToUpdate="FileUpload1" OnServerValidate="valFileType_ServerValidate" Display="Dynamic" />

Then why not uncomment the triggers? You do want the updatepanel to update, don't you?
