I have the following chunk of code:

        private void PopulateGrids()

        {



            //Get project cache

            List<ProjectEnterpriseCustomFieldContainer> list = EnterpriseCustomFieldsStorege.GetInstance().Projec tEnterpriseCustomFields[

                new Guid(application.ActiveProject.GetServerProjectGui d())];





            Dictionary<string, ProjectEnterpriseCustomFieldContainer> allFields = new Dictionary<string, ProjectEnterpriseCustomFieldContainer>();



            list.ForEach(delegate(ProjectEnterpriseCustomField Container container) { allFields.Add(container.FieldName, container); });



            List<ProjectEnterpriseCustomFieldContainer> listStartUp = GetBindingList(allFields, htStartUp);

            List<ProjectEnterpriseCustomFieldContainer> listDelivery = GetBindingList(allFields, htDelivery);

            List<ProjectEnterpriseCustomFieldContainer> listReference = GetBindingList(allFields, htReference);

            List<ProjectEnterpriseCustomFieldContainer> listSPSS = GetBindingList(allFields, htSPSS);





            if (origlistSPSS == null)

            {



                origlistSPSS.AddRange(listSPSS.GetRange(0, 23));



                origlistStartUp = listStartUp;

                origlistReference = listReference;

                origlistDelivery = listDelivery;

            }

            }

I am getting an error "Object reference not set to an instance of an object" on the line origListSPSS.AddRange.

the list origList is declared as: List<ProjectEnterpriseCustomFieldContainer> origlistSPSS;

If anybody has any ideas that would be appreciated - I cannot see why I cannot add the elements to the list?



Thanks

You can't call the AddRange method on origListSPSS until it is instantiated.

List<ProjectEnterpriseCustomFieldContainer> origlistSPSS = new List<ProjectEnterpriseCustomFieldContainer>();

I just reallized that your code will fail now, because you are checking for origlistSPSS == null. Why are you doing that? Do you mean to check that it is empty? (origlistSPSS.Count == 0)

-Peter

Doh! Please ignore - realised just as I posted the topic!

Thanks for the responses though!

Sorry
