Hello, Bertha,

You can find below a sample code snippet demonstrating how to export a RadBarcode as an image without actually showing it on the form:

private void radButton1_Click(object sender, EventArgs e)

{

RadBarcode radBarcode1 = new RadBarcode();

Telerik.WinControls.UI.Barcode.Symbology.Code39Extended code39Extended1 = new Telerik.WinControls.UI.Barcode.Symbology.Code39Extended();

radBarcode1.Symbology = code39Extended1;

radBarcode1.Value = "123456";

radBarcode1.LoadElementTree();

string fileName = @"..\..\exported.png";

Image img = radBarcode1.ExportToImage();

img.Save(fileName, System.Drawing.Imaging.ImageFormat.Png);

Process.Start(fileName);

}

I hope this information helps. If you need any further assistance please don't hesitate to contact me.

Hello, Stefan,

The ExportToImage method has several overloads which allow you to specify the size of the exported image. Thus, you can control how big the bar code image will be.

If I understand your question correctly you would like to specify the size of the RadBarcode itself. To achieve this you can use the Width and Height properties:

RadBarcode radBarcode1 = new RadBarcode();
radBarcode1.Width = 50;
radBarcode1.Height = 50;

I hope this helps. Should you have other questions please let me know.

Hi, Stefan,

I have attached a sample project for your reference. The following image is obtained on my end:
