Adding button in Parameter window

[WHICKED]

I am looking to put a button in the parameters that someone can click on and it would then open up a URL link.

Is that possible?

Hello WHICKED,

Thank you for your post.

This is possible, however it is not officially supported. We do have an unsupported example that you can reference:

https://forum.ninjatrader.com/forum/ninjatrader-8/strategy-development/1182871-how-to-add-button-on-settings-panel-in-ninjatrader-8?p=1182878#post1182878

Note: This requires a reference to C:\Program Files\NinjaTrader 8\bin\System.Windows.Controls.WpfPropertyGrid.dll

This thread will remain open for any users who may want to assist or provide an unsupported solution.

here is the code that I came up with:

public class ShowHelp : System.Windows.Controls.WpfPropertyGrid.PropertyEditor
    {
        public ShowHelp()
        {
            InlineTemplate = CreateTemplate();
        }
    
        System.Windows.DataTemplate CreateTemplate()
        {
            const string xamlTemplate = @"
                <DataTemplate xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation'
                              xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml'>
                    <Grid>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width='*'/>
                        </Grid.ColumnDefinitions>
    
                        <Button x:Name='helpButton' Grid.Column='0' Content='Click here for help'
                                HorizontalAlignment='Center' VerticalAlignment='Center'/>
                    </Grid>
                </DataTemplate>";
    
            var context = new ParserContext();
            context.XmlnsDictionary.Add("", "http://schemas.microsoft.com/winfx/2006/xaml/presentation");
            context.XmlnsDictionary.Add("x", "http://schemas.microsoft.com/winfx/2006/xaml");
    
            System.Windows.DataTemplate template = (System.Windows.DataTemplate)System.Windows.Markup.XamlReader.Parse(xamlTemplate, context);
    
            // Add event handler dynamically after the template is loaded
            template.LoadContent(); // This loads the content defined by the DataTemplate
            if (template.LoadContent() is FrameworkElement rootElement && rootElement.FindName("helpButton") is Button helpButton)
            {
                helpButton.Click += OnHelpButtonClick;
            }
    
            return template;
        }
    
        private void OnHelpButtonClick(object sender, System.Windows.RoutedEventArgs e)
        {
            string url = "http://google.com";
            try
            {
                System.Diagnostics.Process.Start(url);
                System.Diagnostics.Debug.WriteLine("Browser launched successfully.");
            }
            catch (Exception ex)
            {
                System.Diagnostics.Debug.WriteLine("Failed to launch browser: " + ex.Message);
            }
        }
    }​

but when clicking on the button - nothing happens

Hello WHICKED,

As this code is unsupported, we unfortunately cannot provide support for debugging however this thread will remain open for any forum users who may want to assist.

Hello WHICKED,

While undocumented and not officially supported, i've slightly modified the example linked by Gaby.
