Hello,

 If I want to add the formula Dynamically without using the Formula builder it does not calculate the Formula. I am using the latest version of the product, that is 8.3. I wonder if there is a hotfix or I am doing anything wrong.

 Here is what I am doing:

I added a WinGrid on a form then added these codes:

//To fiil the first column when loaded

        private void Form1_Load(object sender, EventArgs e)
        {
            DataTable table = new DataTable();
            table.Columns.Add("Age", typeof(int));
            this.ultraGrid1.DataSource = table;

            DataRow row = table.NewRow();
            row["Age"] = 12;
            table.Rows.Add(row);
            row = table.NewRow();
            row["Age"] = 13;
            table.Rows.Add(row);
            row = table.NewRow();
            row["Age"] = 14;
            table.Rows.Add(row);
            row = table.NewRow();
            row["Age"] = 15;
            table.Rows.Add(row);

//add a caculated UnBound column

            UltraGridColumn newColumn = this.ultraGrid1.DisplayLayout.Bands[0].Columns.Add( "Age2");
            newColumn.Formula = "[Age]*2";

        }

It adds the column but without any data.
