Add OpenFileDialog to Indicator

[habibalex]

How do I add that open file dialog box to an NT8 indicator?

Hello habibalex,

Thanks for your post.

In NT8 you would need to use a property editor. Here is an example that will provide a field in the UI that will display the default sound file (that you assign in State.SetDefaults) and if you move the mouse over property, the field will then show "Choose file". When you left click on the field, a standard windows explorer will open to the sounds folder.

[Display(Name="CrossAbove sound", Description="Enter Up sound file path/name", Order=2, GroupName="Cross Detection Actions")]
[PropertyEditor("NinjaTrader.Gui.Tools.FilePathPick er", Filter="Wav Files (*.wav)|*.wav")]
public string UpSoundFile
{ get; set; }

For your convenience, I have attached the file SamplePropertyEditorforFiles.zip that will demonstrate.

Hello PaulH, great example, thank You.
Is there a similar way to choose folder?

Hello fx.practic,

Thanks for your post.

If you change the filter from Filter="Wav Files (*.wav)|*.wav") to Filter=""), does that meet your needs?

Sorry, it not works:
1. Not showing default value in grid property.
2. Dialog still shows "File name".
3. If to remove "File name" - no reaction when clicking OK button.

Here is a brief video: https://www.screencast.com/t/Uljk251f

I did exactly this:

[NinjaScriptProperty]
[Display(GroupName="03. Use_ML",  Order=1)]
[PropertyEditor ("NinjaTrader.Gui.Tools.FilePathPicker" , Filter= "" )]
public string MlDataFilePath  { get ; set ; }

Hello fx.practic,

Thanks for your reply and for testing that.

I don't have an answer for you on a folder picker property editor.

If I run across something I will post it here.

Will be waiting, thank You.
