Private images As New Dictionary(Of String, Image)()
For Each file In Directory.GetFiles("../../Flags/", "*.png")
    Dim img As Image = Image.FromFile(file)
    If img IsNot Nothing Then
        Dim name As String = Path.GetFileNameWithoutExtension(file)
        images.Add(name, img)
    End If
Next file
EditingFieldExtensionsWin.Instance.RegisterImageCollectionEditor("Nationality", "Nationality", images)

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.

C#
VB.NET

csharp

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";

Imports DevExpress.XtraReports.UI
'...
Private report As New XtraReport1()
Private pictureBox As XRPictureBox = TryCast(report.Bands("ReportHeader").FindControl("xrPictureBox1", True), 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 or reset to the initial image.

Note

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