Series starting with null value


Recommended Posts


I get NullReferenceException when I bind an array of nullable intergers which starting with a null value. For instance:

 myChart.DataSourceSettings.DataSource = new ListProvider(new int?[] { null, 1, 2, 3, 4 }); // NullReferenceException thrown. 

Is there any way to walk around this problem? I do want that null value as a placeholder.

The ListProvider does not support nullable value type at this point.

You will need to pass an array of doubles like this:

myChart.DataSourceSettings.DataSource = new ListProvider(new double[] { Chart.Hidden, 1, 2, 3, 4 });

Or you can use the Data API to pass the values one by one.

We will fix issue this in the next Service Pack.
