DevExpress GridView MVC-设置数据不触发

Question

我目前正在测试DevExpress GridView组件的可能性。我已经创建了一个自定义数据映射，但是在更改行/单元格后似乎未触发e.IsSetData事件。

返回的对象总是像

DataRowModel {ID =“ SomeValue”，Properties = NULL};

非常感谢您的帮助。

请在下面找到网格逻辑和模型对象。

先谢谢了。 康斯坦丁

settings.CustomUnboundColumnData += (s, e) =>
        {
            var dynamicProperties = Model.DataRowModels[e.ListSourceRowIndex].Properties;

            if (dynamicProperties != null)
            {
                var propertyIdString = e.Column.FieldName;
                var currentValueColumn = dynamicProperties.SingleOrDefault(p => p.PropertyId.ToString().Equals(propertyIdString));

                if (currentValueColumn != null)
                {

                    if (e.IsGetData)
                    {
                        if (currentValueColumn == null)
                        {
                            return; 
                        }

                        switch (currentValueColumn.RenderType)
                        {
                            case RenderType.String:
                                e.Value = currentValueColumn.StringValue;
                                break;
                            case RenderType.Integer:
                                e.Value = currentValueColumn.IntValue;
                                break;
                            case RenderType.Boolean:
                                e.Value = currentValueColumn.BooleanValue;
                                break;
                            case RenderType.DateTime:
                                e.Value = currentValueColumn.DateTimeValue;
                                break;
                            default:
                                e.Value = currentValueColumn.StringValue;
                                break;
                        }
                    }

                    if (e.IsSetData && e.Value != null)
                    {
                        currentValueColumn.StringValue = e.Value.ToString();
                    }
                }
            }
        };


  public class DataRowModel
{
    public int Id{ get; set; }                     -----> The correct value
    public List<DataProperty> Properties { get; set; }  ------> This is always null
}
