Hello,
I'm trying to use a custom palette for the series in my bar chart because the Telerik-skin seems to contain only 6 default colors.
But when I create a custom palette the way shown below, the first 7 bar series are getting the default colors. Only series 8 and 9 are in the colors I created.
With a pie chart (1 series with 9 items) everything works fine.
Does anybody know this problem?

Best regards
Rayko

Hello Rayko,

You need to set
RadChart.SkinsOverrideStyles = false;

That should do the trick.

All the best,

Hello Joshua,
Unfortunately that doesn't work. I've already tried it before.

Hello Rayko,

Please, configure the series palette before creating the series. That is -- move the call to SetSeriesColors() method before the call to CreateBar().

Hello Ves,

I've set SkinsOverrideStyles="false" and SetSeriesColors() before CreateBar(). With no effect. The first 7 colors of the bar chart are still from Telerik skin (7th same as first).

Best regards

Hi Rayko,

Please, use this code:

ColorBlend[] seriesColors = new ColorBlend[] {
                new ColorBlend(new Color[] { Color.Red, Color.Red}),
                new ColorBlend(new Color[] { Color.Yellow, Color.Yellow}),
                new ColorBlend(new Color[] { Color.Black, Color.Black}),
                new ColorBlend(new Color[] { Color.Blue, Color.Blue}),
                new ColorBlend(new Color[] { Color.White, Color.White}),
                new ColorBlend(new Color[] { Color.Green, Color.Green}),
                new ColorBlend(new Color[] { Color.MediumPurple, Color.MediumPurple}),
                new ColorBlend(new Color[] { Color.Brown, Color.Brown}),
                new ColorBlend(new Color[] { Color.Orange, Color.Orange}),
                new ColorBlend(new Color[] { Color.Gray, Color.Gray})

Hello Ves,
Thank you. That was it!
It doesn't matter if I set SkinsOverrideStyles or use SetSeriesColors() before CreateBar(). All I have to do is using ColorBlend ;-}

Best regards
