    I would like to do pattern fills in chart series bars rather than just colors. I gather that this is something that could probably be done with custom rendering but I was hoping you might have thought about this and have some sample code that you could show rather than me trying to reinvent the wheel.

    Hello Steve,

    Thank you for writing.

    By default, the bar fill supports a 4 color gradient, for example, you can set it like this:
    private void radButton1_Click(object sender, EventArgs e)
    {
        foreach (BarPointElement item in radChartView1.Series[0].Children)
        {
            item.NumberOfColors = 4;
            item.GradientStyle = Telerik.WinControls.GradientStyles.Linear;
            item.BackColor = Color.Red;
            item.BackColor2 = Color.Green;
            item.BackColor3 = Color.Blue;
            item.BackColor4 = Color.Black;
        }
    }

    If this is not sufficient for your case, you will need to use the custom rendering and manually paint the fill. 

    I hope this will be useful.
