Predefined Images

The following code snippet demonstrates how you can specify the PredefinedImages property.

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

//...

Dictionary<string, Image> images = new Dictionary<string, Image>();
foreach (var file in Directory.GetFiles("Images/Flags/", "*.png")) {
        Image img = Image.FromFile(file);
        if (img != null) {
                string imageName = Path.GetFileNameWithoutExtension(file);
                images.Add(imageName, img);
        }
};
ImageEditorOptions imageEditorOptions = new ImageEditorOptions() {
        AllowLoadImage = false,
        AllowChangeSizeOptions = false,
        AllowDraw = false,
        AllowClear = true
};
foreach (var image in images)
        imageEditorOptions.PredefinedImages.Add(new ImageCollectionItem(image.Value, image.Key));
EditingFieldExtensionsWin.Instance.RegisterImageEditor("Nationality", "Nationality", imageEditorOptions);

Do not specify image captions or set the AllowSearchPredefinedImages property to false if search within the image collection is not required.

If you want to allow end users to only choose an image in the predefined collection, you can use the RegisterImageCollectionEditor method instead of the RegisterImageEditor(String, String, ImageEditorOptions) method. The RegisterImageCollectionEditor method takes an image collection directly, as a parameter.
