How to: Format Text in LabelControl Using HTML Tags

• Oct 25, 2019

The following example shows how to format a LabelControl‘s text using HTML tags. HTML formatting is enabled with the LabelControl.AllowHtmlString property. To respond to end-user clicks on a hyperlink, the LabelControl.HyperlinkClick event is handled. The image below shows the result:

C#

labelControl1.Text = "<size=14>Size = 14<br>" +
                     "<b>Bold</b> <i>Italic</i> <u>Underline</u><br>" + 
                     "<size=11>Size = 11<br>" + 
                     "<color=255, 0, 0>Sample Text</color></size>" +
                     "<href=www.devexpress.com>Hyperlink</href>";
labelControl1.AllowHtmlString = true;
labelControl1.Appearance.TextOptions.WordWrap = DevExpress.Utils.WordWrap.Wrap;
labelControl1.Appearance.Options.UseTextOptions = true;
labelControl1.AutoSizeMode = DevExpress.XtraEditors.LabelAutoSizeMode.Vertical;

private void labelControl1_HyperlinkClick(object sender, DevExpress.Utils.HyperlinkClickEventArgs e) {
    System.Diagnostics.Process.Start(e.Link);
}

VB.NET

labelControl1.Text = "<size=14>Size = 14<br>" + _
                     "<b>Bold</b> <i>Italic</i> <u>Underline</u><br>" +  _
                     "<size=11>Size = 11<br>" + _
                     "<color=255, 0, 0>Sample Text</color></size><br>" + _
                     "<href=www.devexpress.com>Hyperlink</href>"
labelControl1.AllowHtmlString = True
labelControl1.Appearance.TextOptions.WordWrap = DevExpress.Utils.WordWrap.Wrap
labelControl1.Appearance.Options.UseTextOptions = True
labelControl1.AutoSizeMode = DevExpress.XtraEditors.LabelAutoSizeMode.Vertical

Private Sub LabelControl1_HyperlinkClick(sender As Object, e As DevExpress.Utils.HyperlinkClickEventArgs) Handles LabelControl1.HyperlinkClick
    System.Diagnostics.Process.Start(e.Link)
End Sub

Note

The TextOptions.Trimming option, specified within the control’s Appearance.TextOptions section, has no effect if the caption is HTML-formatted text.
