FilePathPicker

[cls71]

When I use the NinjaTrader.Gui.Tools.FilePathPicker in the properties of an indicator, I get an exception when click the field.

Are there any restrictions for use this PropertyEditor?

Thanks

Hello cls71,

Thank you for writing in. I am currently investigating this and will update you tomorrow morning.

Thank you for your patience in the meantime.

What is the skinny on this please? I need to be able to to have a standard Windows File picker window pop up for the user.

Hello,

Using this file picker requires a filter. For example:

[PropertyEditor("NinjaTrader.Gui.Tools.FilePathPicker", Filter="Any Files (*.)|*.")]

It also defaults to the sounds folder as this is the only instance in which it is used.

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

Capital, but for a few errors in your supplied code, and the default location. Your code as supplied will never show files, only folders. Correct is:

[PropertyEditor("NinjaTrader.Gui.Tools.FilePathPicker", Filter="Any Files (*.*)|*.*")]

Of course, one can use any filter, such as Wav Files (*.wav)|*.wav" instead.

It defaults not to the sounds folder, but to the NT User Folder, C:\Users\userName\Documents\NinjaTrader 8.

Regardless, thanks for showing me the path forward!

Edit: Interestingly enough, if one uses

[PropertyEditor("NinjaTrader.Gui.Tools.FilePathPicker", Filter="Wav Files (*.wav)|*.wav")]

it does default to the sounds folder. I have not tested any other file extensions.
