XRControl.ToImage() Method

Returns a graphical representation of a control.

Namespace: DevExpress.XtraReports.UI

Assembly: DevExpress.XtraReports.v18.2.dll

Declaration

C#

public virtual Image ToImage()

VB.NET

Public Overridable Function ToImage As Image

Returns

Type	Description
Image	A Image object which represents a graphical representation of a control.

Remarks

Use the ToImage method to obtain an image from any report control. Later this image can be used either for a Web representation of the control, or saved to a file for future use.

Note

A control can’t be saved to an image if it doesn’t belong to a report. Therefore, if you’re creating a separate report control, first add the control to any report to call the ToImage method.

Example

The following code demonstrates how to use the ToImage method. It first creates a label, sets a couple of its properties, adds it to the label, and then creates an image of the label and saves it to a file.

C#

using System.Drawing;
using DevExpress.XtraReports.UI;
// ...

public void CreateControlImage() {
    // Create a label and adjust its properties.
    XRLabel label = new XRLabel();
    label.BackColor = Color.Red;
    label.Text = "XRLabel";

    // Create an empty report and add a label to it.
    XtraReport report = new XtraReport();
    report.Bands.Add(new DetailBand());
    report.Bands[0].Controls.Add(label);

    // Create an image from the label and save it to a disk.
    Image img = label.ToImage();
    img.Save("C:\\output.jpg");
}

VB.NET

Imports System.Drawing
Imports DevExpress.XtraReports.UI
' ...

Public Sub CreateControlImage()
    ' Create a label and adjust its properties.
    Dim label As New XRLabel()
    label.BackColor = Color.Red
    label.Text = "XRLabel"

    ' Create an empty report and add a label to it.
    Dim report As New XtraReport()
    report.Bands.Add(New DetailBand())
    report.Bands(0).Controls.Add(label)

    ' Create an image from the label and save it to a disk.
    Dim img As Image = label.ToImage()
    img.Save("C:\\output.jpg")
End Sub
