public virtual bool RegisterImageCollectionEditor(
    string name,
    string displayName,
    IEnumerable<Image> images,
    bool sizeOptionsEnabled


Name Type Description
name String

The name of the registered image collection editor.

displayName String

The display name of the registered image collection editor.

images IEnumerable<Image>

The editor’s image collection.

sizeOptionsEnabled Boolean

true if the editor allows end users to set up the image’s size and alignment options; otherwise, false.


Type Description

true if the image list has been successfully registered; otherwise, false.


Use this method to register an image editor with a collection of predefined images in the application.

using System.Collections.Generic;
using System.Drawing;
using System.IO;
using DevExpress.XtraPrinting.Preview;

List<Image> images = new List<Image>();
foreach (var file in Directory.GetFiles("../../Flags/", "*.png")) {
    Image img = Image.FromFile(file);
    if (img != null) {
EditingFieldExtensionsWin.Instance.RegisterImageCollectionEditor("Nationality", "Nationality", images, false);

To use this editor for image editing in Print Preview, set a XRPictureBox control’s EditOptions | Enabled property to true and the EditOptions | EditorName property - to the registered editor’s name.

Set image edit options in the end-user Report Designer’ Property Grid.


The following sample demonstrates how to do this in code.

using DevExpress.XtraReports.UI;
XtraReport1 report = new XtraReport1();
XRPictureBox pictureBox = report.Bands["ReportHeader"].FindControl("xrPictureBox1", true) as XRPictureBox;
pictureBox.EditOptions.Enabled = true;
pictureBox.EditOptions.EditorName = "Nationality";

When an end user clicks the Picture Box in Print Preview, the assigned editor activates. This editor allows end users to choose a predefined image, set up its size and alignment, and reset the initial image.



Use the RegisterImageEditor(String, String, ImageEditorOptions) method instead if you need to add the Brush Options and/or Load Image menu items as well.
