Example

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.

Follow the steps below to create a sample project.

1. Start Visual Studio 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.

   C#

   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);
   }
   

   VB.NET

   Imports DevExpress.XtraPrinting.HtmlExport
   Imports DevExpress.XtraPrinting.HtmlExport.Controls
   Imports DevExpress.XtraReports.UI
   ' ...
   
   Private Sub xrLabel1_HtmlItemCreated(sender As Object, e As HtmlEventArgs)
       ' Clear content of the currently processed item.
       e.ContentCell.Controls.Clear()
   
       ' Create a check box. 
       Dim checkBox As New DXHtmlGenericControl(DXHtmlTextWriterTag.Input)
       checkBox1.Attributes("checked") = "true"
       checkBox1.Attributes("type") = "CheckBox"
   
       ' Create a hyperlink. 
       Dim hypLink As 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)
   End Sub
   

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

C#

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 { }
}

VB.NET

Imports System
Imports System.Windows.Forms
Imports System.Diagnostics
' ...

Private Sub ExportToHTML()
    Dim report As New XtraReport1()
    report.ExportToHtml("Test.html")
    StartProcess("Test.html")
End Sub

Public Sub StartProcess(ByVal path As String)
    Dim process As New Process()
    Try
        process.StartInfo.FileName = path
        process.Start()
        process.WaitForInputIdle()
    Catch
    End Try
End Sub
