Namespace : DevExpress.XtraBars.Navigation

Assembly : DevExpress.XtraBars.v25.2.dll

NuGet Package : DevExpress.Win.Navigation

Declaration

csharp

[Browsable(false)]
public int ImageIndex { get; set; }

<Browsable(False)>
Public Property ImageIndex As Integer

Property Value

Type	Description
Int32

The index of the image displayed in the element header.

Remarks

The ImageIndex property specifies the index of the required image in the image collection (AccordionControl.Images).

It’s also possible to assign an image to the element using the AccordionControlElementBase.Image property.

If images are specified via both the ImageIndex and Image properties, the image assigned to the Image property will be used.

By default, the auto-height feature is enabled for element headers. It adjusts the header height to accommodate the contents (image, text, custom control and context buttons) in their entirety. The AccordionControlElementBase.ImageLayoutMode property allows you to limit the image display height and specify the way the assigned image is scaled.

Tip

You can also assign an image by its name in the collection.

C#
VB.NET

csharp

// The image collection is created and populated with images at design time.
barItem.ImageOptions.Image = imageCollection1["technology_32x32"]; 
// Assign an SVG image in the SvgCollection
// barItem.ImageOptions.SvgImage = svgCollection1["technology_32x32"];

' The image collection is created and populated with images at design time.
barItem.ImageOptions.Image = imageCollection1("technology_32x32")
' Assign an SVG image in the SvgCollection
' barItem.ImageOptions.SvgImage = svgCollection1["technology_32x32"];
