Remarks

You can apply CustomItemImageAttribute to a CustomItemMetadata object when you create metadata for a custom dashboard item. The attribute identifies an icon for a custom item’s bar in the Ribbon. The file that is used for an icon must be embedded to an assembly where the file is located. Make sure the file’s Build Action property is set to Embedded Resource.

The way in which you can specify an icon depends on the icon file’s location:

• The icon is located in the same assembly where the CustomItemMetadata object is defined.

  Pass a path to the file as an argument to the CustomItemImageAttribute constructor.

  C#

  using DevExpress.DashboardCommon;
  
  namespace CustomItemsSample {
    [CustomItemImage("CustomItemsSample.Images.Funnel.svg")]
    public class CustomFunnelMetadata : CustomItemMetadata {
      //...
    }
  }
  

  VB.NET

  Imports DevExpress.DashboardCommon
  
  Namespace CustomItemsSample
    <CustomItemImage("Funnel.svg")> _
    Public Class CustomFunnelMetadata
      Inherits CustomItemMetadata
    '...
    End Class
  End Namespace
  

• The icon is located in another assembly.

  To identify another assembly, pass both a path to the file and any class type from the assembly where the file is located to the CustomItemImageAttribute constructor.

  C#

  using DevExpress.DashboardCommon;
  
  namespace CustomItemsSample {
    [CustomItemImage("CustomImages.Images.CustomItemImage.svg", typeof(CustomerType))]
    public class CustomFunnelMetadata : CustomItemMetadata {
      //...
    }
  }
  

  VB.NET

  Imports DevExpress.DashboardCommon
  
  Namespace CustomItemsSample
    <CustomItemImage("CustomImages.Images.CustomItemImage.svg", GetType(CustomerType))> _
    Public Class CustomFunnelMetadata
      Inherits CustomItemMetadata
    '...
    End Class
  End Namespace
