C# Telerik WinForms RadGridView创建和填充运行时

我的问题与此非常相似

但是我不想创建数据表

这是网格视图

 GridView = new RadGridView
            {
                    AutoSizeRows = true,
                    BeginEditMode = RadGridViewBeginEditMode.BeginEditProgrammatically,
                    Location = new Point(0, 130),
                    Name = "GridView",
                    ShowRowErrors = false,
                    Size = new Size(390, 100),
                    TabIndex = 0,
                    Visible = false
            };

此方法在运行时创建列

 private List<GridViewTextBoxColumn> InitializeColumns()
    {
        var result = new List<GridViewTextBoxColumn>();

        {
            var columnId = new GridViewTextBoxColumn
                {
                    Name = "RecordID",
                    HeaderText = "ID",
                    FieldName = "RecordID",
                    MaxLength = 50,
                    Width = 50,
                    DataType = typeof(int)
                };
            result.Add(columnId);
        }

        {
            var columnInformation = new GridViewTextBoxColumn
                {
                    Name = "RecordInformation",
                        HeaderText = "Information",
                        FieldName = "RecordInformation",
                        MaxLength = 50,
                        Width = 250,
                        DataType = typeof(string)
                };
            result.Add(columnInformation);
        }

        {
            var columnRowType = new GridViewTextBoxColumn
            {
                Name = "RecordType",
                HeaderText = "Type",
                FieldName = "RecordType",
                MaxLength = 50,
                Width = 250,
                DataType = typeof(string)
            };
            result.Add(columnRowType);
        }

        return result;
    }

因此，我将列表绑定到网格视图。列显示良好，但不显示数据。必须有一个记录。我错过了什么？

这是我放在表单上的全部代码，效果很好：

    {
        base.OnLoad(e);

            Location = new Point(0, 130),
            Name = "GridView",
            ShowRowErrors = false,
            Size = new Size(390, 100),
