Hi Mike,

i have seen this example http://devcenter.infragistics.com/Support/KnowledgeBaseArticle.aspx?ArticleID=10019 but it does not satisfy my req. I'll make an example to explain better: Suppose you have to sum some(or all) cells on a grid and the result sum with a value on an ultranumeric editor and last divide it by a number. Can i do this calcs using only an ultracalcmanager? for example create a named reference1 that holds the sum value of the cell, then create another named reference2 that holds the value of the first namedRef plus the value of the ultranumeric editor...

thank you.

ps.I dont want to use summaries to get the value sum of the cells

Good point. You really would not be able to fix it in a case like that unless you knew the name of the reference that the CalcReference for the grid is using interally. I think it goes something like: "_band_0". Like I said, this is almost certainly a bug.

Fortunately i'm using datatable, but how can i fix this problem if i have a custom List of object as a datasource of the grid? something like this

public class Person
    {
        private String _Name;
        private double _Salary;

        public double Salary
        {
            get { return _Salary;}
            set { _Salary = value; }
        }

        public string Name
        {
            get { return _Name; }
            set { _Name = value; }
        }
    }

        ultraGrid2.DataSource = TestData2();

        public List<Person> TestData2()
        {
            List<Person> persons = new List<Person>();

            Person ps = new Person();
            ps.Salary = 1500;
            ps.Name = "John";

            Person ps1 = new Person();
            ps1.Salary = 2100;
            ps1.Name = "Jim";

            persons.Add(ps);
            persons.Add(ps1);

            return persons;
        }

ps:I have submited a new incident.

Hi Mike,

perhaps its a syntax problem on the formula. I have made a simple example and attached to this discussion. It is a form that has a wingrid with 1 column and an ultranumericeditor. Basically i want to sum all cells of this column and the result multiplied by 2, finally show this result on the ultranumericeditor.

thank you.

Hi Walter.

This all sounds like a pretty simple case of using formulas to me. I'm having a hard time understanding what you are asking for here. Are you having trouble with the syntax? Or setting up a NamedReference? Or applying a formula to an UltraNumericEditor?

Personally, I would use a NamedReference for anything you don't need to display to the user. It doesn't make sense to use a control just to calculate a formula that is never displayed.

To sum grid column in a NamedReference, you would use the Sum function and pass in the grid column reference.
