Getting the BlogGroupID from the current CSContext

I am trying to do a Server Control that needs to be aware of the current blogs
BlogGroupID. So if the control is put in i.e the Skin-BlogSideBar.ascx, the
control should know which BlogGroupID the current blog belongs to.

I have been using CSContext.Current.BlogGroupID for that, but it seems to give
me a value of -1 regardless of which blog I go to. Is there a different way I
should do this?

The code in BaseBlogPage, that looks up the "current" blog is:

 

        protected virtual Weblog WeblogLookUp()
        {
            if(_weblog == null)
            {
                CSContext context = CSContext.Current;

                if(context.SectionID > 0)
                {
                    _weblog = Weblogs.GetWeblog(context.SectionID,true,false);
                    SetCookie(_weblog);
                }
                else
                {
                    HttpCookie cookie =
context.Context.Request.Cookies[CreateApplicationCookieName(context,"weblog
")];
                    if(cookie != null)
                    {
                       
if(!Globals.IsNullorEmpty(cookie.Values["BlogID"]))
                        {
                            int bid =
Int32.Parse(cookie.Values["BlogID"]);
                            try
                            {
                                _weblog = Weblogs.GetWeblog(bid,true,false);
                            }
                            catch{}
                        }
                    }
                }
                        
                if(_weblog == null)
                {
                    ArrayList blogs = Weblogs.GetWeblogs(true,false,false);
                    blogs =
Sections.FilterByAccessControl(blogs,Permission.Post,context.User);

                    if(blogs != null && blogs.Count == 1)
                    {
                        _weblog = blogs[0] as Weblog;
                        SetCookie(_weblog);
                    }
                }

                if(_weblog == null)
                    Response.Redirect("switch.aspx");

            }

            return _weblog;
        } 

 

 

And from there you can query the GroupID of the blog.

I am not sure what you mean, I am not going to edit the source code, but are
going to query the API, in this case CSContext.Current.BlogGroupID to get the
blogID.

The question is, is there a way to use the CSContext class to get the blog group
of the current blog?

Is your control being used on a Blog page?  
Is your control inheriting WeblogThemedControl?

In WeblogTemplatedWebControl the following code gets the current blog from
CSContext.Current.


 


                    string appKey = CSContext.Current.ApplicationKey;
                    if(appKey == null)
                        appKey = WeblogConfig.DefautApplicationKey;

                    weblog = Weblogs.GetWeblog(appKey,true);

 

 BlogGroupID in CSContext is just an alias for
Request.QueryString["blogGroupID"], which returns -1 if no
querystring/ value is present.
