Question

I have dynamically added a few items to my Menu Strip and triggered and event for each item added to the strip (items are added from an XML file).
What I’m trying to do next is to pass the text from each item to the event handler so I can use them in a thread. Is it possible to this? Can anyone help me with a solution please?

This is my code:

private void historyMenuItem_Click(object sender, EventArgs e){
    XmlDocument doc = new XmlDocument();  // create new xml document
    doc.Load("..\\history.xml");  // load the xml
    // create a new node list
    // and select nodes from BookItems/Book
    XmlNodeList nodeList = doc.SelectNodes("URLs/http"); 

    historyMenuItem.DropDownItems.Clear();
    foreach (XmlNode node in nodeList) {
        string page = node.Attributes["page"].Value;
        //http://msdn.microsoft.com/en-us/library/ms160990.aspx
        ToolStripMenuItem windowNewMenu = new ToolStripMenuItem(page, null, new EventHandler(MenuItemClickHandler));
        historyMenuItem.DropDownItems.Add(windowNewMenu);
    }
}

private void MenuItemClickHandler(object sender, EventArgs e){
    ToolStripMenuItem clickedItem = (ToolStripMenuItem)sender;
    ## HERE IS WHERE I NEED HELP:
    UrlTextBox = (I need value of page here!);
    this.thread = new Thread(new ThreadStart(this.httpRequestMultiThread));
    this.thread.Start();
}

I would suggest you to use Tag Property. It is object so you need to know to which type to cast it when you want to use it. Something like this

private void historyMenuItem_Click(object sender, EventArgs e)
    {
        XmlDocument doc = new XmlDocument();  // create new xml document
        doc.Load("..\\history.xml");  // load the xml
        XmlNodeList nodeList = doc.SelectNodes("URLs/http");  // create a new node list
                                                              // and select nodes from BookItems/Book
        historyMenuItem.DropDownItems.Clear();
        foreach (XmlNode node in nodeList)   // for each node in the node list
        {
            string page = node.Attributes["page"].Value;

            ToolStripMenuItem windowNewMenu = new ToolStripMenuItem(page, null, new EventHandler(MenuItemClickHandler));
            windowMenuItem.Tag = page;
            historyMenuItem.DropDownItems.Add(windowNewMenu);
        }
    }
private void MenuItemClickHandler(object sender, EventArgs e)
{
    ToolStripMenuItem clickedItem = (ToolStripMenuItem)sender;

    UrlTextBox.Text = (string)clickedItem.Tag;
    this.thread = new Thread(new ThreadStart(this.httpRequestMultiThread));
    this.thread.Start();
}
