Adding pages to DocumentWindow

[Szabolcs]

Hi, I have a problem and can't find a solution for it:
I have this code that should add a new page to the ...UI.Docking.DocumentWindow on Form1. If I use it on a button on Form1 works fine, but if I try to call it from Form2 the code runs through and show's the messageBox on the end but it doesn't add the page, here's the code:

private void mNextP1_Click(object sender, EventArgs e)
{
    string txt = File.ReadAllText("c:\\1.html");
    string style = File.ReadAllText("c:\\styles.css");

    Form f = new Form();
    f.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
    f.Dock = DockStyle.Fill;
    WebBrowser wb = new WebBrowser();
    wb.DocumentText = "";
    wb.Dock = DockStyle.Fill;
    doc = wb.Document.DomDocument as IHTMLDocument2;
    doc.designMode = "On";
    doc.write(txt);
    IHTMLStyleSheet styleSheet = doc.createStyleSheet("", 0);
    styleSheet.cssText = style;

    f.Controls.Add(wb);

    DocumentWindow dw = new DocumentWindow();
    f.TopLevel = false;

    dw.Controls.Add(f);
    f.Show();
    dw.Text = "Contents";
    radDock1.AddDocument(dw);
    radDock1.ActiveWindow = dw;

    MessageBox.Show("Done");
}

This one works just fine, but here comes the problem:
I have this on my form2:

Form1 form1 = new Form1();
form1.newBlankProject();

and the code for "form1.newBlankProject();" is the same as above, but for some reason it only show's the messagebox with the text "Done2" and nothing else happens. Here's the code for that one too:

public void newBlankProject()
{
    string txt = File.ReadAllText("c:\\1.html");
    string style = File.ReadAllText("c:\\styles.css");

    Form f = new Form();
    f.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
    f.Dock = DockStyle.Fill;
    WebBrowser wb = new WebBrowser();
    wb.DocumentText = "";
    wb.Dock = DockStyle.Fill;
    doc = wb.Document.DomDocument as IHTMLDocument2;
    doc.designMode = "On";
    doc.write(txt);
    IHTMLStyleSheet styleSheet = doc.createStyleSheet("", 0);
    styleSheet.cssText = style;

    f.Controls.Add(wb);

    DocumentWindow dw = new DocumentWindow();
    f.TopLevel = false;

    dw.Controls.Add(f);
    f.Show();
    dw.Text = "Contents";
    radDock1.AddDocument(dw);
    radDock1.ActiveWindow = dw;

    MessageBox.Show("Done2");
}

Probably is just a stupid mistake on my part, but I can't figure out what the problem may be, any help or ideas are appreciated,

Thanks,

Hi Szabolsc,

Thank you for writing.

I have looked into your issue and successfully identified your problem. When you use this code into your Form2

Form1 form1 = new Form1();
form1.newBlankProject();

you create a new instance of type Form1, which is different from your original Form1. The solution is to pass the original Form1 to Form2's constructor when creating it, like this:

//Form2 Constructor
public Form2(Form1 form1)
{
    InitializeComponent();
    this.form1 = form1;
}

//Form1 Constructor and Form2 Creation
public Form1()
{
    InitializeComponent();
    this.form2 = new Form2(this);
    this.form2.Show();
}

This way you can always work with the original form and easily call its public methods. Also I am attaching a C# project which shows the complete logic.

if you need any additional help I would be glad to help.
