Remarks
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) {
images.Add(img);
}
}
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.
