How to: Fill Resource Headers with Specific Colors

Dec 17, 2020

This example demonstrates how to fill all resource headers with specific colors obtained from the ASPxScheduler.ResourceColorSchemas collection by handling the ASPxScheduler.CustomizeElementStyle event.

C#
VB.NET

csharp

using DevExpress.Web.ASPxScheduler;
// ...

protected void ASPxScheduler1_CustomizeElementStyle(object sender, CustomizeElementStyleEventArgs e) {
    if (e.ElementType == WebElementType.VerticalResourceHeader) {
        int id = ASPxScheduler1.Storage.Resources.Items.IndexOf(e.Cell.Resource);
        e.Style.BackColor = ASPxScheduler1.ResourceColorSchemas[id % ASPxScheduler1.ResourceColorSchemas.Count].Cell;
    }
}

Imports DevExpress.Web.ASPxScheduler
' ...

Protected Sub ASPxScheduler1_CustomizeElementStyle(ByVal sender As Object, _
                                                   ByVal e As CustomizeElementStyleEventArgs)
    If e.ElementType = WebElementType.VerticalResourceHeader Then
        Dim id As Integer = ASPxScheduler1.Storage.Resources.Items.IndexOf(e.Cell.Resource)
        e.Style.BackColor = ASPxScheduler1.ResourceColorSchemas(id Mod ASPxScheduler1.ResourceColorSchemas.Count).Cell
    End If
End Sub

As a result, resource headers will be colored as time/date cells associated with corresponding resources.
