Embed custom palette in the default ContextMenu

[Travis]

Something like chartview-customization-palettes but not quite. I can define a custom palette simple enough. However, how do we embed it in the default Palettes ContextMenu?

Hi Michael,

Thank you for writing.

To do that you need to capture the ContextMenuOpening event of RadChartView, where you can add your custom item:

radChartView1.ChartElement.ContextMenuOpening += ChartElement_ContextMenuOpening;

...........

void ChartElement_ContextMenuOpening(object sender, ChartViewContextMenuOpeningEventArgs e)
{
    RadMenuItem item = new RadMenuItem();
    item.Text = "Custom palette";
    item.Click += item_Click;
    e.ContextMenu.Items.Add(item);
}

void item_Click(object sender, EventArgs e)
{
    this.radChartView1.Area.View.Palette = new CustomPalette();
}

public class CustomPalette : ChartPalette
{
    public CustomPalette()
    {
        this.GlobalEntries.Add(Color.Yellow, Color.Red);
        this.GlobalEntries.Add(Color.Yellow, Color.Blue);
    }

I hope that you find this information useful. Should you have any other questions, do not hesitate to contact us.
