Exporting and importing custom item property values in Gantt Chart Light Library

In my application (that references Gantt Chart controls from Gantt Chart Light Library) I have defined a CustomGanttChartItem object type inheriting from GanttChartItem adding custom properties to be displayed in the grid and/or referenced in custom task templates. However, I loading and saving Project XML files doesn't support loading and saving the custom item type and the custom values by default. Is there a way I can inject code to handle these situations?

If you want to import and/or export Project XML files from Gantt Chart components when you are using a CustomGanttChartItem object type inheriting from GanttChartItem and defining your own custom properties, you need to:

• Create an instance of GanttChartDataGrid.ProjectXmlSerializer or GanttChartView.ProjectXmlSerializer, referring your component instance as a constructor parameter;
• Handle ProjectXmlSerializer.GanttChartItemLoading and/or ProjectXmlSerializer.GanttChartItemSaving to inject code for loading and saving the custom items;
• Use e.GanttChartItem, e.SourceElement, and/or e.OutputXml to read and write data from and to XML or custom item object instances, as necessary:

var loader = new GanttChartDataGrid.ProjectXmlSerializer(GanttChartDataGrid);
loader.GanttChartItemLoading +=
    delegate(object sender, GanttChartView.ProjectXmlSerializer.GanttChartItemLoadingEventArgs e)
    {
        // Implement method yourself:
        // CustomGanttChartItem GetNewItem(GanttChartItem partialItem, XElement sourceXml);
        e.GanttChartItem = GetNewItem(e.GanttChartItem, e.SourceElement);
    };
loader.Load(stream);

var saver = new GanttChartDataGrid.ProjectXmlSerializer(GanttChartDataGrid);
saver.GanttChartItemSaving +=
    delegate(object sender, GanttChartView.ProjectXmlSerializer.GanttChartItemSavingEventArgs e)
    {
        // Implement method yourself:
        // string GetXml(string partialXml, CustomGanttChartItem item);
        e.OutputXml = GetXml(e.OutputXml, e.GanttChartItem as CustomGanttChartItem);
    };
saver.Save(stream);
