Ninja properties grid

[traderpards]

Remember that thread where I asked for help on implementing a TreeView and together we figured it out? http://ninjatrader.com/support/forum...ad.php?t=83864

When the user clicks on a node in the tree, I want to bring up a property grid that has various properties associated with that particular tree node. I found three free ones on the web. The one that looks the nicest is the one from CodePlex and I got it to work great when you put the strategy on a chart. The properties loaded and changed and saved and did everything nicely. But when you put the same strategy on another chart, the property grid was unresponsive - no properties loaded on the second chart. The WPFPropertyGrid provided a clue. When you brought up the strategy on a second chart and invoked the GUI, you got an error message something to the effect that you can't use this control because another process owns it. I don't remember exactly but it's the same message you get when you try to implement a button on the toolbar without wrapping the calls in "this.Dispatcher.Invoke((Action)(() => }));" The one from SoftFluent works OK and even works in multiple instances but there are some annoying quirks with that one.

I'd consider buying one but it's difficult to tell if it will actually work and since none of the free ones have a color picker I'm not sure any one that I'd pay for would either.

Is there any way I can talk you into making the Ninjatrader properties grid available to someone who wants to inherit from it or outright use it? Or is it already available and I just don't know how to access it?

Hello,

There would be no need to use any other property grid as NT8 already has one implemented. You can utilize most of the same controls that are found in the platform, you would simply need to reference them in the NinjaScript side to use them.

Here is a simple test I created a while back that implements a PropertyGrid in an addon, you would likely do a similar process using any other type. This does not implement a MVVM pattern, but I am certain you could migrate it into your current code just seeing a basic use example.

To import this item:

• First open a NinjaScript editor and reference the file: C:\Program Files (x86)\NinjaTrader 8\bin64\System.Windows.Controls.WpfPropertyGrid.dl l
• Compile, ensure there are no errors and restart the platform to ensure the assembly is loaded.
• Import the zip file.
• Click New -> Sample PropertyGrid Addon
• Click New -> Chart -> Any instrument and any settings
• Add any indicator to the chart
• Now in the addon window, click Refresh. Likely you will get a "collection source can not be modified" error, ignore this and you should see the object displayed in the property grid.

This is not a complete sample and is not intended to be, this was simply a test if you could utilize a PropertyGrid which demonstrates the needed syntax.

A reference to the file C:\Program Files (x86)\NinjaTrader 8\bin64\System.Windows.Controls.WpfPropertyGrid.dl l is included as a reference, but would be required for any custom project that utilizes the property grid.

For completeness, there are some additional samples for this specific grid at this github. Some of these will work in NT8 while others may not, looking in the samples there can be additional xaml required for some of the items which may or may not be in NT8. https://github.com/DenisVuyka/WPG/tree/master/Samples

Please let me know if I may be of further assistance.

That's the ticket! And it has a color picker too!
Thanks!!!
