Hi,

the cell value in an pragramatically created Cell of type boolean is always false, even, if the grafically shown value is true.

this is the creation code (bold marked cells ar programmatically added, the other columns are initialized by DataSource:

        private void ultraTreeRequirements_ColumnSetGenerated(object sender, ColumnSetGeneratedEventArgs e)
        {
            switch (e.ColumnSet.Key)
            {
                case " ":
                    e.ColumnSet.Columns["ID"].Visible = false;
                    break;
                case "RequirementsList":
                    // e.ColumnSet.Columns["ID"].Visible = false;
                    e.ColumnSet.Columns["hardwareName"].Visible = false;
                    e.ColumnSet.Columns["GroupType_ID"].Visible = false;
                    e.ColumnSet.Columns["Type_ID"].Visible = false;
                    e.ColumnSet.Columns["ECU_Requirement_Items"].Visible = false;
                    e.ColumnSet.Columns["ECU_Deliverys"].Visible = false;
                    e.ColumnSet.Columns.Add("Check").DataType = typeof(bool);
                    e.ColumnSet.Columns["Check"].AllowCellEdit = AllowCellEdit.Full;
                    e.ColumnSet.Columns["datumLieferdatum"].Visible = false;
                    e.ColumnSet.Columns["datumStichtag"].Visible = false;
                    e.ColumnSet.Columns["Owner"].Visible = false;
                    break;
                case "":
                case "ChildWorkpiecesGroupList":
...

                  break;
            }
        }

Now i try to read the cell value as follows:

        private void ultraTreeRequirements_CellValueChanged(object sender, CellValueChangedEventArgs e)
        {
            if ((!e.Node.IsBandNode) && (e.Node.BandName == "RequirementsList") && (e.Cell.Column.Key == "Check"))
            {
                bool cellValue = (bool)e.Cell.Value;
                return;
            }
        }       

Even, if the shown value at the GUI is true, the readed value by code in cellValue is always false. What is my Problem?

Thanks and Greatings: Rudy
