Assembly: DevExpress.XtraReports.v20.2.dll


public virtual WinControlImageType ImageType { get; set; }
Public Overridable Property ImageType As WinControlImageType

Property Value

Type Default Description


A value that specifies whether to render a control inside the WinControlContainer as a bitmap or as a metafile.


This property is in effect when a control inside the WinControlContainer is rendered as an image. See the PrintMode property description for more information.

Use the ImageType property to specify whether to render a control inside the container as a metafile image or as a bitmap. A metafile's image quality is always good, but certain parts of the control may be lost. A bitmap's quality may be poorer, but a control is rendered more accurately.

The following images demonstrate how controls are rendered to metafiles or bitmaps.

System.Windows.Forms control ImageType = Metafile ImageType = Bitmap
Button WinControl.Button.Metafile.png WinControl.Button.Bitmap.png
TextBox with some text WinControl.TextBox.Metafile.png WinControl.TextBox.Bitmap.png

To ensure Microsoft Azure compatibility, set the ImageType property to WinControlImageType.Bitmap or set the AzureCompatibility.Enable property to true.


The code sample below creates a DataGridView control instance and adds this instance to a report. The sample specifies that the DataGridView control is printed as a bitmap image.

using System.Windows.Forms;
using DevExpress.XtraReports.UI;
// ...
// Create an XtraReport instance.
XtraReport report = new XtraReport() {
    Bands = {
        new DetailBand()
// Create a DataGridView control instance.
DataGridView dataGridView = new DataGridView();
// Create a WinControlContainer instance for the data grid.
WinControlContainer winControlContainer = new WinControlContainer();
// Place the data grid inside the WinControlContainer.
winControlContainer.WinControl = dataGridView;
// Specify that the WM_PAINT message is used to print the control inside the WinControlContainer.
winControlContainer.DrawMethod = WinControlDrawMethod.UseWMPaint;
// Specify that the control inside the WinControlContainer is always printed as an image.
winControlContainer.PrintMode = WinControlPrintMode.AsImage;
// Specify that the printed image is a bitmap, not a metafile.
winControlContainer.ImageType = WinControlImageType.Bitmap;
// Specify that the control should synchronize its bounds with the WinControlContainer's bounds.
winControlContainer.SyncBounds = true;
// Add the printable component container to the report.
