DevExpress Raster Image Chooser
DevExpress Vector Image Chooser
You can choose whether to add the selected image to the report or project resources. If you add the image to project resources, you can reuse it in several reports.
Project Resources
Report Resources
End-User Report Designer
When you specify the ImageSource property in an End-User Report Designer, the Open File dialog is invoked.
The selected image is saved to the report definition .repx file.
Assign an Image from the Report’s Image Collection
You can use the report’s ImageResources collection to set PictureBox controls’ ImageSource property.
Invoke the PictureBox‘s smart tag. Click the Expression option’s ellipsis button to invoke the Expression Editor. Choose an image from the Images collection:
Bind to the Report Data Source’s Field
Invoke the control’s smart tag. Expand the Expression drop-down list and select a data field.
You can bind the ImageSource property to a database field that contains image data as Base64 encoded strings.
Refer to the PictureBox class description for more information on how to bind this control to the report data source’s field.
Use Image URL
If you want to save only a path to the image, and not the image itself, use the XRPictureBox.ImageUrl property instead.
Note
After you set the XRPictureBox.ImageUrl property’s value, the ImageSource property is set to null (Nothing in Visual Basic).
After you set the ImageSource property’s value, the XRPictureBox.ImageUrl property is set to Empty.

This example demonstrates how to create an XRPictureBox object and specify its properties.
using DevExpress.XtraPrinting;
using DevExpress.XtraPrinting.Drawing;
using DevExpress.XtraReports.UI;
using System.Drawing;
// ...
public XRPictureBox CreateXRPictureBox()
{
// Create an XRPictureBox instance.
XRPictureBox xrPictureBox = new XRPictureBox();
// Specify an image for the created XRPictureBox instance.
xrPictureBox.ImageSource = ImageSource.FromFile("Images\\Flags\\United_States_of_America.png");
// Uncomment these lines to get images from a data source.
// ExpressionBinding expressionBinding = new ExpressionBinding("BeforePrint", "ImageSource", "[Picture]");
// xrPictureBox.ExpressionBindings.Add(expressionBinding);
// Position the picture box within a document.
xrPictureBox.LocationF = new PointF(150F, 25F);
// Set the picture box size.
xrPictureBox.SizeF = new SizeF(160F, 120F);
// Set the picture box size mode.
xrPictureBox.Sizing = ImageSizeMode.AutoSize;
// Specify that the image in the picture box should use the default DPI value.
