Examples

The following code example shows how to initialize a PageContent object that includes two delegate methods. One delegate method adds additional detail information to a business object, and the other delegate method converts a business object to a DetailGroup, which is contained in a DetailColumnCollection:

protected override PageContent CreateContent()
{
    PageContent page = PageContent.Create<BusinessObject>(
        CreateListProvider(), 
        CreateListColumns(), 
        CreateTasks(), 
        GetDetails, 
        ConvertBusinessObject);

    return page;
}

private static DetailColumnCollection GetDetails(DetailBusinessObject detailObj)
{
    DetailColumnCollection columns = new DetailColumnCollection();
    DetailColumn column = new DetailColumn();
    DetailGroup group = new DetailGroup("Hardware Information");

    group.Add("Computer Name", detailObj.ComputerName);
    group.Add("CPU", detailObj.Cpu);
    group.Add("Disk", detailObj.Disk);
    group.Add("RAM", detailObj.Ram);

    column.Add(group);
    columns.Add(column);

    return columns;
}

private DetailBusinessObject ConvertBusinessObject(BusinessObject businessObj)
{
    DetailBusinessObject detailObj = new DetailBusinessObject();

    detailObj.ComputerName = businessObj.ComputerName;
    detailObj.Cpu = "2.5 GHz";
    detailObj.Disk = 350 GB";
    detailObj.Ram = "4 GB";

    return detailObj;
}
