How to hide webpart in sharepoint only for specific user or case

Question

I have PublishingLayoutPage and depends on query params i should hide few webparts.

But i dont now how to do this. Because if i understand problem correctly SPLimitedWebPartManager will hide webpart for all users!

            using (SPLimitedWebPartManager mgr = file.GetLimitedWebPartManager(PersonalizationScope.Shared))
                        {
                            try
                            {
                                SPLimitedWebPartCollection webparts = mgr.WebParts;
                                foreach (System.Web.UI.WebControls.WebParts.WebPart wp in webparts)
                                {
                                    if (wp is MyWebpart && !isShowWebpart)
                                    {
wp.Hidden=true;
                                        mgr.SaveChanges(wp );
                                    }
                                }

How to hide webpart and doesnot allow to render content only for specific case on page?

Answer 1

It sounds like you could place this in your Load/PreRender/wherever is appropriate:

    List<string> webPartTitlesToHide = new List<string>();
    webPartTitlesToHide.Add("Long Title");
    webPartTitlesToHide.Add("Long Content");
    webPartTitlesToHide.Add("Long Footer");


    if (Request["view"] == "short")
    {
        WebPartManager wpm = WebPartManager.GetCurrentWebPartManager(this);
        foreach (WebPart wp in wpm.WebParts)
        {
            if (webPartTitlesToHide.Contains(wp.Title))
            { 
                wpm.CloseWebPart(wp);
            }
        }
    }

Obviously, you probably have a better way of selecting which webparts to hide, but this is just an example.
