#Property Value
Type | Default | Description |
---|---|---|
Int32 | -1 | An integer value that specifies the image by its zero-based index within the source collection; -1 displays no image. |
#Remarks
The ImageIndex property specifies the index of the required image in the collection of images. The source of images is specified by the ColumnView.Images property.
It is also possible to assign an image to a column header directly using the GridColumn.ImageOptions.Image
property.
The image below shows examples of band header and column header images.
Tip
You can also assign an image by its name in the collection.
// 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"];
