Hi all,

I recently encountered an issue with the breadcrumb control of DotNetNuke (to be found under /admin/skins). I am using the DPS payment on the site and when this redirects to the original site it uses a get-variable with the name "userid" this causes an issue with breadcrumb because of the property "ProfileUserId" which is also referring to the very same variable name. (The DPS-UserId is a string whereas the ProfileUserId is of type Int32 which results in a cast exception).

Here is how I fixed it:

        public int ProfileUserId
        {
            get
            {
                var userId = Null.NullInteger;
                if (!string.IsNullOrEmpty(Request.Params["UserId"]))
                {
                    // Original below
                    //userId = Int32.Parse(Request.Params["UserId"]);
                    // *** FIX START ***
                    // Fixed as the original could lead to an exception when the 
                    // request string is not a number (int32)
                    if (!Int32.TryParse(Request.Params["UserId"], out userId))
                        userId = Null.NullInteger;
                    // *** FIX END ***
                    
                }
                return userId;
            }
        }

As the original line (" userId = Int32.Parse(Request.Params["UserId"]); ") could allways result in an exception causing a page not to load, I would suggest to alter this to the provided code above.

Cheers
