Declaration

C#

[DefaultValue(WinControlImageType.Metafile)]
[SRCategory(ReportStringId.CatBehavior)]
public virtual WinControlImageType ImageType { get; set; }

VB.NET

<DefaultValue(WinControlImageType.Metafile)>
<SRCategory(ReportStringId.CatBehavior)>
Public Overridable Property ImageType As WinControlImageType

Property Value

Type	Default	Description
WinControlImageType	Metafile	A value that specifies whether to render a control inside the WinControlContainer as a bitmap or as a metafile.

Available values:

Name	Description
Metafile	The control is rendered as a metafile. In this case the quality of the rendered image is always good, but in some cases some details of the control may be lost.
Bitmap	The control is rendered as a bitmap. In this case the quality of the rendered image is sometimes poor, but it allows a control to be drawn more precisely.

Remarks

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
TextBox with some text

Note

To ensure Microsoft Azure compatibility, set the ImageType property to WinControlImageType.Bitmap.

Example

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.

C#

using DevExpress.XtraReports.UI;
using System.Windows.Forms;
// ...
// Create an XtraReport instance.
XtraReport report = new XtraReport()
{
    Bands = {
        new DetailBand()
    }
};
// Create a DataGrid control instance.
DataGridView dataGridView = new DataGridView();
// Create a PrintableComponentContainer instance for the data grid.
PrintableComponentContainer printableComponentContainer = new PrintableComponentContainer();
// Place the data grid inside the printable component container.
printableComponentContainer.WinControl = dataGridView;
// Specify that the control inside the printable component container is always printed as an image.
printableComponentContainer.PrintMode = WinControlPrintMode.AsImage;
// Specify that the control inside the printable component container is always printed as a bitmap.
printableComponentContainer.WindowControlOptions.ImageType = WinControlImageType.Bitmap;
// Add the printable component container to the report.
report.Bands[BandKind.Detail].Controls.Add(printableComponentContainer);

VB.NET

' Specify that the control inside the printable component container is always printed as an image.
printableComponentContainer.PrintMode = WinControlPrintMode.AsImage
' Specify that the control inside the printable component container is always printed as a bitmap.
printableComponentContainer.WindowControlOptions.ImageType = WinControlImageType.Bitmap
' Add the printable component container to the report.
report.Bands(BandKind.Detail).Controls.Add(printableComponentContainer)
