To reproduce: - Localize the palette names with the localization provider. - Change the palette with the context menu. Workaround: class MyChartDataPointElementController : ChartDataPointElementController { protected override RadContextMenu CreatePaletteMenu() { RadContextMenu menu = new RadContextMenu(); RadChartLocalizationProvider localizationProvider = RadChartLocalizationProvider.CurrentProvider; RadMenuItem paletteItem = new RadMenuItem(localizationProvider.GetLocalizedString(RadChartStringId.Palette)); menu.Items.Add(paletteItem); RadMenuItem item = new RadMenuItem(localizationProvider.GetLocalizedString(RadChartStringId.PaletteArctic)); item.Click += new System.EventHandler(item_Click); item.Tag = "Arctic"; paletteItem.Items.Add(item); item = new RadMenuItem(localizationProvider.GetLocalizedString(RadChartStringId.PaletteAutumn)); item.Click += new System.EventHandler(item_Click); item.Tag = "Autumn"; paletteItem.Items.Add(item); item = new RadMenuItem(localizationProvider.GetLocalizedString(RadChartStringId.PaletteCold)); item.Click += new System.EventHandler(item_Click); item.Tag = "Gold"; paletteItem.Items.Add(item); item = new RadMenuItem(localizationProvider.GetLocalizedString(RadChartStringId.PaletteFlower)); item.Click += new System.EventHandler(item_Click); item.Tag = "Flower"; paletteItem.Items.Add(item); item = new RadMenuItem(localizationProvider.GetLocalizedString(RadChartStringId.PaletteForest)); item.Click += new System.EventHandler(item_Click); item.Tag = "Forest"; paletteItem.Items.Add(item); item = new RadMenuItem(localizationProvider.GetLocalizedString(RadChartStringId.PaletteGrayscale)); item.Click += new System.EventHandler(item_Click); item.Tag = "Grayscale"; paletteItem.Items.Add(item); item = new RadMenuItem(localizationProvider.GetLocalizedString(RadChartStringId.PaletteGround)); item.Click += new System.EventHandler(item_Click); item.Tag = "Ground"; paletteItem.Items.Add(item); item = new RadMenuItem(localizationProvider.GetLocalizedString(RadChartStringId.PaletteLilac)); item.Click += new System.EventHandler(item_Click); item.Tag = "Lilac"; paletteItem.Items.Add(item); item = new RadMenuItem(localizationProvider.GetLocalizedString(RadChartStringId.PaletteMetro)); item.Click += new System.EventHandler(item_Click); item.Tag = "Metro"; paletteItem.Items.Add(item); item = new RadMenuItem(localizationProvider.GetLocalizedString(RadChartStringId.PaletteNatural)); item.Click += new System.EventHandler(item_Click); item.Tag = "Natural"; paletteItem.Items.Add(item); item = new RadMenuItem(localizationProvider.GetLocalizedString(RadChartStringId.PalettePastel)); item.Click += new System.EventHandler(item_Click); item.Tag = "Pastel"; paletteItem.Items.Add(item); item = new RadMenuItem(localizationProvider.GetLocalizedString(RadChartStringId.PaletteRainbow)); item.Click += new System.EventHandler(item_Click); item.Tag = "Rainbow"; paletteItem.Items.Add(item); item = new RadMenuItem(localizationProvider.GetLocalizedString(RadChartStringId.PaletteSpring)); item.Click += new System.EventHandler(item_Click); item.Tag = "Spring"; paletteItem.Items.Add(item); item = new RadMenuItem(localizationProvider.GetLocalizedString(RadChartStringId.PaletteSummer)); item.Click += new System.EventHandler(item_Click); item.Tag = "Summer"; paletteItem.Items.Add(item); item = new RadMenuItem(localizationProvider.GetLocalizedString(RadChartStringId.PaletteWarm)); item.Click += new System.EventHandler(item_Click); item.Tag = "Warm"; paletteItem.Items.Add(item); item = new RadMenuItem(localizationProvider.GetLocalizedString(RadChartStringId.PaletteWindows8)); item.Click += new System.EventHandler(item_Click); item.Tag = "Windows8"; paletteItem.Items.Add(item); item = new RadMenuItem(localizationProvider.GetLocalizedString(RadChartStringId.PaletteSun)); item.Click += new System.EventHandler(item_Click); item.Tag = "Sun"; paletteItem.Items.Add(item); return menu; } void item_Click(object sender, System.EventArgs e) { RadMenuItem item = sender as RadMenuItem; if (item != null) { this.Area.View.Palette = ChartPalette.FromKnownPalette(item.Tag.ToString()); } } } // change the controller this.radChartView1.Controllers.Add(new MyChartDataPointElementController());
