DetailsView image updating problem

Question

I have DetailsView with users Info (Name, Email, Picture). That DetailsView control can be edited. Values are from DataBase

 protected void DVUserInfoShow_ItemUpdating(object sender, DetailsViewUpdateEventArgs e)
{


    FileUpload EditAvatar = (FileUpload)DVUserInfoShow.FindControl("EditAvatar");
    if (EditAvatar.HasFile)
    {
        string image_path = "~/images/user_images/" + EditAvatar.FileName;
        EditAvatar.SaveAs(Server.MapPath(image_path));
        e.NewValues["Avatar"] = EditAvatar.FileName;

    }

    else
    {
        e.NewValues["Avatar"] = e.OldValues["Avatar"];
    }



}

The problem is with e.NewValues["Avatar"] = e.OldValues["Avatar"];, when user updates his name and email, the picture value is set to null. And that code doesn't work. What I'm doing wrong?

OldValues collection is only available when DetailView is bounded with a declarative DataSource, otherwise OldValues collection will contain null in ItemUpadting event.

What you can do is inside DVUserInfoShow_ItemUpdating event, get current data from database and save in some local variables.

Now i know the answer, i used declarative DataSource, but it didn't work anyway.. The problem was that i didn't set DataKeyNames.. – RaShe Feb 08 '12 at 01:59
