Remarks

This property is in effect when a control inside the PrintableComponentContainer 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 meta file’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 controlImageType = MetafileImageType = 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.

csharp
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
Imports DevExpress.XtraReports.UI
' ...
' Create an XtraReport instance.
Dim report = New XtraReport()
Dim band = New DetailBand()
report.Bands.Add(band)
' Create a DataGrid control instance.
Dim dataGridView As New DataGridView()
' Create a PrintableComponentContainer instance for the data grid.
Dim printableComponentContainer As 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)
