I am trying to change the background colors of individual bars to red and green
TryCast(RadHtmlChart1.PlotArea.Series(0), BarSeries).SeriesItems(0).BackgroundColor = System.Drawing.Color.Red.
Chart works great and I am binding to a datatable
RadHtmlChart1.DataSource = DifferenceDT
The error is on SeriesItems (Out of Range) and count is 0 when I inspect.
Am I doing something wrong?
Here is my .aspx code
