Examples

The following example demonstrates how to use the XRControl.HtmlItemCreated event to customize the content of an XRLabel control, when a report is exported to HTML. In the event handler, create two custom HTML elements, which will display a check box and a hyperlink on a Web page, and add them to the control's content using the HtmlEventArgs.ContentCell property of the event parameter.

For this example to work correctly, do the following.

  1. Start Microsoft Visual Studio 2010, 2012, 2013, 2015 or 2017, and create a new Windows Forms Application or open an existing one.
  2. Add a new report (named XtraReport1) to the application.
  3. Drop an XRLabel control onto a report and handle its HtmlItemCreated event as follows.

    using DevExpress.XtraPrinting.HtmlExport;
    using DevExpress.XtraPrinting.HtmlExport.Controls;
    using DevExpress.XtraReports.UI;
    // ...
    
    private void xrLabel1_HtmlItemCreated(object sender, HtmlEventArgs e) {
        // Clear content of the currently processed item.
        e.ContentCell.Controls.Clear();
    
        // Create a check box. 
        DXHtmlGenericControl checkBox = new DXHtmlGenericControl(DXHtmlTextWriterTag.Input);
        checkBox1.Attributes["checked"] = "true";
        checkBox1.Attributes["type"] = "CheckBox";
    
        // Create a hyperlink. 
        DXHtmlAnchor hypLink = new DXHtmlAnchor();
        hypLink.InnerText = "XtraReports Web Page";
        hypLink.HRef = "https://www.devexpress.com/Subscriptions/Reporting/";
    
        // Add the created elements to the item's content. 
        e.ContentCell.Controls.Add(checkBox);
        e.ContentCell.Controls.Add(hypLink);
    }
    

Then, to export a report to HTML, you can use code similar to the following.

using System;
using System.Windows.Forms;
using System.Diagnostics;
// ...

private void ExportToHTML() {
    XtraReport1 report = new XtraReport1();
    report.ExportToHtml("Test.html");
    StartProcess("Test.html");
}

public void StartProcess(string path) {
    Process process = new Process();
    try {
        process.StartInfo.FileName = path;
        process.Start();
        process.WaitForInputIdle();
    }
    catch { }
}
