KeyValuePair<double,double> and a List of these

I've got to display a chart with 4 series in it. I was able to make this work with my data. However, it gives a parse error (see below) when I start updating my lists of data. I.E it gives me an error before even trying to "update" the chart. Heck, I've even remove the chart from the equation and I still get the same parsing error.

Here's how my lists are declared:

public partial class MainWindow : Window
    {
List<KeyValuePair<double, double>> channel1List = new List<KeyValuePair<double, double>>();
        List<KeyValuePair<double, double>> channel2List = new List<KeyValuePair<double, double>>();
        List<KeyValuePair<double, double>> channel3List = new List<KeyValuePair<double, double>>();
        List<KeyValuePair<double, double>> channel4List = new List<KeyValuePair<double, double>>();
        List<List<KeyValuePair<double, double>>> rampsList = new List<List<KeyValuePair<double, double>>>();

In my main, I've got:

 // DEFAULT CHANNEL 1 LIST
            channel1List.Add(new KeyValuePair<double, double>(0, 0));
            channel1List.Add(new KeyValuePair<double, double>(DMIN1, 0));
            channel1List.Add(new KeyValuePair<double, double>(DMAX1, 100));
            channel1List.Add(new KeyValuePair<double, double>(30, 100));
            // DEFAULT CHANNEL 2 LIST
            channel2List.Add(new KeyValuePair<double, double>(0, 0));
            channel2List.Add(new KeyValuePair<double, double>(DMIN2, 0));
            channel2List.Add(new KeyValuePair<double, double>(DMAX2, 100));
            channel2List.Add(new KeyValuePair<double, double>(30, 100));
            // DEFAULT CHANNEL 3 LIST
            channel3List.Add(new KeyValuePair<double, double>(0, 0));
            channel3List.Add(new KeyValuePair<double, double>(DMIN3, 0));
            channel3List.Add(new KeyValuePair<double, double>(DMAX3, 100));
            channel3List.Add(new KeyValuePair<double, double>(30, 100));
            // DEFAULT CHANNEL 4 LIST
            channel4List.Add(new KeyValuePair<double, double>(0, 0));
            channel4List.Add(new KeyValuePair<double, double>(DMIN4, 0));
            channel4List.Add(new KeyValuePair<double, double>(DMAX4, 100));
            channel4List.Add(new KeyValuePair<double, double>(30, 100));


            channel1List.RemoveAt(1);
            channel1List.Insert(1, new KeyValuePair<double, double>(DMIN1, 0));


            // DEFAULT LIST OF RAMPS
            rampsList.Add(channel1List);
            rampsList.Add(channel2List);
            rampsList.Add(channel3List);
            rampsList.Add(channel4List);
            // DRAW DEFAULT CHART
            rampsChart.DataContext = rampsList;

noticed the 2 lines "channel1.RemoveAt(1)..../..." these were just to test, that I am able to remove an entry and replace it with a new one. These series are only 4 points each, and I always need to update only item 1 and 2. 0 and 3 are never updated.

Anyway, this code above works fine. It plots the charts. no parsing error.

Now, like I said I need to udpate this chart when the user is moving a slider. I've got a ValueChanged event set for this slider, which works fine for updating a couple of labels.

But if I had the SAME 2 lines:

channel1List.RemoveAt(1);
channel1List.Insert(1, new KeyValuePair<double, double>(DMIN1, 0));

then it gives me no error when building the project but gives me this error when I hit Start...

An unhandled exception of type 'System.Windows.Markup.XamlParseException' occurred in PresentationFramework.dll

I have no clue why it's doing this.

any idea? thanks Steve

I suspect that your

channel1List.RemoveAt(1);

code is executed before your

channel1List.Add(new KeyValuePair<double, double>(0, 0));
channel1List.Add(new KeyValuePair<double, double>(DMIN1, 0));
channel1List.Add(new KeyValuePair<double, double>(DMAX1, 100));
channel1List.Add(new KeyValuePair<double, double>(30, 100));

which causes this exception

Make sure that order of execution is always correct, for example by calling collection fill method from constructor.
