PivotViewer ItemsLoaded event

Here is an example of the PivotViewer extended to feature an ItemsLoaded event.

This event fires when all the item data templates/trading cards have finished rendering.

Application Library Caching with PRISM

Your main Shell project xap file will reference all your application dependencies with Copy Local = true, which ensures your application has the DLL available.

For each referenced library, if it has been signed and a *.extmap.xml file is found in the same directory as the DLL then a zip file will be created for it in the Web Server ClientBin folder. If not then the DLL will be be copied directly into the Shell.xap.

All your “Module” project / xap files should reference their dependencies with Copy Local = false. This will let Visual Studio build each module project xap files but not copy the referenced libraries into the xap.

For example this is the Prism extmap.xml file:

<?xml version="1.0"?>
<manifest>
  <assembly>
    <name>Microsoft.Practices.Prism</name>
    <version>4.1.0.0</version>
    <publickeytoken>31bf3856ad364e35</publickeytoken>
    <relpath>Microsoft.Practices.Prism.dll</relpath>
    <extension downloadUri="Microsoft.Practices.Prism.zip" />
  </assembly>
</manifest>

AppManifest.xaml

This file is contained within each xap file and lets Silverlight know whether dependencies can be found within the xap or externally.

The “Deployment.Parts” section contains the libraries with Copy to Local = true.

The “Deployment.ExternalParts” section contains libraries with Copy to Local = false.

Note: When PRISM loads modules it does not automatically download ExternalParts, see here. Here is an example of an AppManifest.xaml file:

<Deployment xmlns="http://schemas.microsoft.com/client/2007/deployment" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" EntryPointAssembly="PivotViewerDemo" EntryPointType="PivotViewerDemo.App" RuntimeVersion="5.0.61118.0">
  <Deployment.Parts>
    <AssemblyPart x:Name="PivotViewerDemo" Source="PivotViewerDemo.dll" />
    <AssemblyPart x:Name="System.Xml.Serialization" Source="System.Xml.Serialization.dll" />
    <AssemblyPart x:Name="System.Xml.Linq" Source="System.Xml.Linq.dll" />
  </Deployment.Parts>
  <Deployment.ExternalParts>
    <ExtensionPart Source="System.Windows.Controls.zip" />
    <ExtensionPart Source="System.Windows.Controls.Pivot.zip" />
  </Deployment.ExternalParts>
</Deployment>

Configuring Silverlight application projects (Xap files)

Don’t forget to switch on application library caching for all your Silverlight applications (Shell and module projects).

How to cache your own Silverlight libraries

Simply sign the library (Project > Properties > Signing) by creating a new key file which requires a password then manually create an extmap.xml file:

Where to find the extmap.xml files

If you don’t have access to the extmap.xml files just create them yourself.

You’ll need to know the assembly version number, right click on the file in Windows Explorer, select properties then click the Details tab.

To find out the public key token use the sn.exe (strong name) application that comes with Visual Studio:

See earlier in this blog post for an example of an *.extmap.dll file.

I want to store copies of each of my references within my code base, where can I find the DLLs

While many people use Nuget nowadays you may still wish to store the DLLs files yourself. Here is a quick lust of locations so you can find them.

The Silverlight “core” libraries do not have to be included in either xap or zip files and can always be set to Copy Local False and do not need to be stored within your code base.

Other Microsoft and third party libraries can be added to a libraries (libs) folder within your solution, don’t forget to include the extmap.xml files. Once the files are installed the Microsoft SDK files can be found here:

PRISM libraries can be downloaded from CodePlex: http://compositewpf.codeplex.com/

Expression libraries can be downloaded from Blend SDK, Blend Service Pack, Silverlight Tools SP1, VS 2010 SP1.

Sorting PivotViewer Silverlight5

There is a sort property on the PivotViewerProperty but that’s used to sort the filter on the left hand side of the page (see sector is sorted by quantity, then A-Z on sector).

To sort within a group you need to implement an IComparable interface on an aggregate property. Here’s what I mean:

You’ll see this data is “sorted” by Sector, which actually groups but within each group the data is sorted by coupon (the big number in the middle). Here’s how I did it:

private string sector;
public string Sector
{
    get { return sector; }
    set { sector = value; NotifyProperty("Sector"); }
}

private ValueSortByCoupon sectorSort;
public ValueSortByCoupon SectorSort
{
    get { return sectorSort ?? (sectorSort = new ValueSortByCoupon(Sector, CouponToday)); }
}

....

public class ValueSortByCoupon : IComparable
{
    private string Value { get; set; }
    private decimal Coupon { get; set; }

    public ValueSortByCoupon(string sector, decimal coupon)
    {
        this.Value = sector;
        this.Coupon = coupon;
    }

    public int CompareTo(object rhs)
    {
        var other = (ValueSortByCoupon)rhs;
        var result = this.Value == other.Value
                    ? other.Coupon.CompareTo(this.Coupon)
                    : this.Value.CompareTo(other.Value);
        return result;
    }

    public override string ToString()
    {
        return Value;
    }
}

<pivot:PivotViewer>
    <pivot:PivotViewer.PivotProperties>
        <pivot:PivotViewerStringProperty Id="SectorSort"
                                            DisplayName="Sector"
                                            Options="CanFilter,CanSearchText"
                                            Binding="{Binding SectorSort, Mode=OneWay}" />
    </pivot:PivotViewer.PivotProperties>

Creating Excel file in C#

Before you start you’ll want to install Open XML SDK 2.0 for Microsoft Office:

http://www.microsoft.com/en-us/download/details.aspx?id=5124

Now create a new C# console app and add a reference to the DocumentFormat.OpenXml assembly.

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Spreadsheet;

namespace CreatingExcelFile
{
    class Program
    {
        static void Main(string[] args)
        {
            // Make a copy of the template file.
            File.Copy(@"blank.xlsx", @"generated.xlsx", true);

            // Open the copied template workbook. 
            using (SpreadsheetDocument myWorkbook = SpreadsheetDocument.Open(@"generated.xlsx", true))
            {
                // Access the main Workbook part, which contains all references.
                WorkbookPart workbookPart = myWorkbook.WorkbookPart;

                // Get the first worksheet. 
                WorksheetPart worksheetPart = workbookPart.WorksheetParts.ElementAt(2);

                // The SheetData object will contain all the data.
                SheetData sheetData = worksheetPart.Worksheet.GetFirstChild<SheetData>();

Creating a Metro PivotViewer

using System.Windows.Controls;
using System.Windows.Controls.Pivot;

namespace PivotViewerDemo
{
    public class MetroPivotViewer : PivotViewer
    {
        public override void OnApplyTemplate()
        {
            base.OnApplyTemplate();
            
            // an alternative to changing style is to do magic here...
        }
