Calculate value based on aggregate result value.

My column footers are summed using an aggregate (SumFunction).
I need to calculate the percent of a grand total represented by the sum of each column. The grand total is calculated as a sum function too.

Essentially I'm looking to do the following: (think Excel)

B5/E5 C5/E5 D5/E5 etc...where E5 is the grand total in the totals column and B5, C5 etc are the sums for their respective columns.

I'm following the pattern for creating a custom aggregate. Here is what I have so far. What I need is a way to pass the grand total value to the Percent method. Or if that isn't possible some other approach?

public static double Percent<TSource>(IEnumerable<TSource> source, Func<TSource, int?> selector)
{
  return (source.Select(selector).Aggregate(0, (t1, t2) => t1 + (int)t2) * .01);
}

WPF Dowloads

A couple of questions:

1) The *TRIAL* download page for WPF controls list the following options:

WPF 3.5 - Automatic Installation (msi, 199 MB)
WPF 3.5 - Manual Installation (zip, 193 MB)
WPF 3.5 - DLLs only (zip, 19 MB)
WPF 4 - Manual installation (msi, 92 MB)
WPF 4 - Manual installation (zip, 193 MB)
WPF 4 - DLLs only (zip, 19 MB)

As you can see, There is no "Automatic" installation for the WPF 4 controls? Is that just a typo? is the "WPF 4 - Manual installation (msi, 92 MB)" really supposed to be named "WPF 4 - Automatic installation (msi, 92 MB)"? The link for the payed version appears to label them correctly.

2) the download page also list hot fixes for both 3.5 and 4.0 versions. Do i still have to apply the hot fixes or are they included on the latest full download?

3) If I installed the 3.5 version by mistake and now want to install the 4.0 version. Will the WPF 4.0 installer ask me if I want to upgrade my 3.5 dlls to 4.0 or do I have to do all this manually. If I have to do it manually is there a link that show the steps to follow to make this as painless of a process as possible?

Thank you.

RadGridView SortMemberPath does not update dynamically?

When setting the RadGridView.SortMemberPath = "SomeMemberName", when the model object raises an INotifyPropertyChanged for SomeMemberName, the grid doesn't seem to re-sort.

Is this the expected behavior?

I'm trying to display dynamically updated data in the grid, where I want to sort the column on some arbitrary member property in the model (e.g. display CPU history in a column and sort on the 10 second average).

How can I make sure that the grid automatically re-sorts when a member in the model is updated?

Thanks,
Alex

Grouping By Date

The following code produces a bar chart showing average request amount grouped by year and type:

List<RequestData> produceList = new List<RequestData>();

produceList.Add(new RequestData("2", 132, DateTime.Today, "Cash Grants"));

produceList.Add(new RequestData("1", 145, DateTime.Today.AddYears(1), "Cash Grants"));

produceList.Add(new RequestData("3", 149, DateTime.Today.AddYears(1).AddDays(1), "Cash Grants"));

produceList.Add(new RequestData("4", 187, DateTime.Today, "Cash Grants"));

produceList.Add(new RequestData("5", 186, DateTime.Today.AddYears(1), "Matching Gifts"));

produceList.Add(new RequestData("6", 131, DateTime.Today, "Dinners & Events"));

produceList.Add(new RequestData("7", 173, DateTime.Today.AddYears(1), "Dinners & Events"));

produceList.Add(new RequestData("8", 172, DateTime.Today, "Matching Gifts"));

produceList.Add(new RequestData("9", 140, DateTime.Today.AddYears(1), "Cash Grants"));

produceList.Add(new RequestData("10", 129, DateTime.Today, "Dinners & Events"));

produceList.Add(new RequestData("11", 158, DateTime.Today, "Matching Gifts"));

produceList.Add(new RequestData("12", 164, DateTime.Today.AddYears(1).AddDays(1), "Dinners & Events"));

SeriesMapping seriesMapping = new SeriesMapping();

seriesMapping.SeriesDefinition = new HorizontalBarSeriesDefinition();

seriesMapping.GroupingSettings.GroupDescriptors.Add(new ChartGroupDescriptor("Type"));

seriesMapping.GroupingSettings.GroupDescriptors.Add(new ChartYearGroupDescriptor("RequestDate"));

seriesMapping.ItemMappings.Add(new ItemMapping("RequestAmount", DataPointMember.YValue, ChartAggregateFunction.Sum));

seriesMapping.ItemMappings.Add(new ItemMapping("RequestDate", DataPointMember.XCategory));

radChart.SeriesMappings.Add(seriesMapping);

radChart.ItemsSource = produceList;

radChart.DefaultView.ChartArea.AxisX.DefaultLabelFormat = "yyyy";

However, if I change the order of the data so that item 12 comes directly after item 3 like so:
