DashboardPalette | A DashboardPalette object that specifies a palette used to color dashboard item elements. |
Remarks
DevExpress Dashboard uses a set of 20 unique colors from the default palette. On the server, you can use the following events to create your own palette with custom colors:
Use the static read-only DashboardPalette.Default field to get the default palette.
The following example illustrates how to substitute the default palette with a custom palette for a specified dashboard. Create and initialize the DashboardPalette class instance and assign the resulting object to the e.Palette
event parameter:
using DevExpress.DashboardCommon;
using DevExpress.DashboardWeb;
using System.Drawing;
void Default_CustomPalette(object sender, CustomPaletteWebEventArgs e) {
if (e.DashboardId == "SalesByCategory") {
// Create a new custom palette.
List<Color> customColors = new List<Color>();
customColors.Add(Color.LightBlue);
customColors.Add(Color.Aquamarine);
customColors.Add(Color.SkyBlue);
customColors.Add(Color.LightCoral);
customColors.Add(Color.Tomato);
customColors.Add(Color.IndianRed);
customColors.Add(Color.Violet);
customColors.Add(Color.Plum);
customColors.Add(Color.MediumOrchid);
// Assign a newly created custom palette to the Web Dashboard.
e.Palette = new DashboardPalette(customColors);
}
}
