You can implement some interfaces in your tool or your tool control to extends its capability in XrmToolBox. The list of interfaces can be found below

IGitHubPlugin interface

Implement this interface in PluginControlBase derived class

Implements this interface to add a menu in XrmToolBox when your plugin is opened and visible. This menu allows to redirect the user to the Issues page of the specified GitHub repository.

#region IGitHubPlugin implementation

public string RepositoryName => "GithubRepositoryName";

public string UserName => "GithubUserName";

#endregion IGitHubPlugin implementation

IPayPalPlugin interface

Implement this interface in PluginControlBase and/or in PluginBase derived class

If you implement the interface in the PluginControlBase class, it adds a menu in XrmToolBox when your plugin is opened and visible



if you implement the interface in the PluginBase class, it allows your tool to be listed in tools that accept donation when a user click on a general link to make a donation (coming in February 2021).

#region IPayPalPlugin implementation

public string DonationDescription => "paypal description";

public string EmailAccount => "paypal@paypal.com";

#endregion IPayPalPlugin implementation

IHelpPlugin interface

Implement this interface in PluginControlBase derived class

Implements this interface to add a menu in XrmToolBox when your plugin is opened and visible. This menu allows to redirect the user to a web help page.

#region IHelpPlugin implementation

public string HelpUrl => "http://www.google.com";

#endregion IHelpPlugin implementation

IStatusBarMessenger interface

Implement this interface in PluginControlBase derived class

Implement this interface to allow your plugin to send process progress information to XrmToolBox main application. This information can be displayed as text, progress bar or both in the XrmToolBox status bar.
The event needs implementing in your derived class too, as shown.

public event EventHandler SendMessageToStatusBar;

private void SomeMethod()
{
	// If you want to notify the user of progress, through the
	// status bar, use the following method
	SendMessageToStatusBar?.Invoke(this, new StatusBarMessageEventArgs(50, "progress at 50%"));
}

private void SomeFinalMethod()
{
	// If you want to clear the message in the status bar use a blank argument like below
	SendMessageToStatusBar(this, new StatusBarMessageEventArgs(string.Empty));

}


IDuplicatableTool interface
Implement this interface in PluginControlBase derived class

Implement this interface to allow your tool to be duplicated when right clicking on its tab header. You can pass state from the source tool instance to the new opened instance

#region IDuplicatableTool implementation

public event EventHandler DuplicateRequested;

public void ApplyState(object state)
{
    txtState.Text = state.ToString();
}

public object GetState()
{
    return txtState.Text;
}

private void tsbDuplicate_Click(object sender, EventArgs e)
{
    DuplicateRequested?.Invoke(this, new DuplicateToolArgs("My custom state", true));
}

#endregion IDuplicatableTool implementation


IShortcutReceiver interface
Implement this interface in PluginControlBase derived class

Implements this interface to allow your tool to receive user keyboard inputs

#region Shortcut Receiver implementation

public void ReceiveKeyDownShortcut(KeyEventArgs e)
{
    //   MessageBox.Show("A KeyDown event was received!");
}

public void ReceiveKeyPressShortcut(KeyPressEventArgs e)
{
    // MessageBox.Show("A KeyPress event was received!");
}

public void ReceiveKeyUpShortcut(KeyEventArgs e)
{
    //MessageBox.Show("A KeyUp event was received!");
}

public void ReceivePreviewKeyDownShortcut(PreviewKeyDownEventArgs e)
{
    //MessageBox.Show("A PreviewKeyDown event was received!");
}

public void ReceiveShortcut(KeyEventArgs e)
{
    MessageBox.Show(e.ToString());
}

#endregion Shortcut Receiver implementation


IMessageBusHost interface
Implement this interface in PluginControlBase derived class

Implement this interface to allow cross tools communication. See documentation from Jonas Rapp

IAboutPlugin interface
Implement this interface in PluginControlBase derived class

Implements this interface to display an About menu for your tool in XrmToolBox Help menu. Do whatever you want when this menu is clicked

#region IAboutPlugin implementation

public void ShowAboutDialog()
{
    MessageBox.Show(@"This is a sample tool", @"About Sample Tool", MessageBoxButtons.OK, MessageBoxIcon.Information);
}

#endregion IAboutPlugin implementation


ISettingsPlugin interface
Implement this interface in PluginControlBase derived class

Implements this interface to add a Settings menu for your tool in XrmToolBox Configuration menu

#region ISettingsPlugin implementation

public void ShowSettings()
{
    MessageBox.Show(@"Settings should be displayed instead of this dialog");
}

#endregion ISettingsPlugin implementation


IPrivatePlugin interface
Implement this interface in PluginControlBase derived class

Implements this interface to instruct XrmToolBox to not report tool opening to Application Insights

INoConnectionRequired interface

Implement this interface in PluginBase derived class

Implement this interface if your plugin does not need a connection before being opened.
