Grey Out Properties Options for User Based on ENUM

[happypappy]

I have created an ENUM in the properties menu, I want to disable or grey out other user properties if the ENUM selects one. So if I pick EMA for example disable DynamicPT so they user can't change it from the default.

Has anyone done this before?

 
public enum type{SMA,EMA};
 
#region Properties
[Description("Profit target")]
[GridCategory("Parameters")]
public int PT
{
get { return pt; }
set { pt = Math.Max(1, value); }
}
[Description("Dynamic profit target")]
[GridCategory("Parameters")]
public bool Dynamicpt
{
get { return DynamicPT; }
set { DynamicPT = value; }
}
[Description("Type one for entry chart, type two for hedge chart")]
[GridCategory("Parameters")]
public strat StratType
{
get { return stratType; }
set { stratType = value; }
}
#endregion

Hello happypappy,

Thank you for your post.

I am not sure how you would gray out the option, but you could check for the enum in the OnBarUpdate() or OnStartUp() and then set the parameters per the enum option thus overriding what the user has set.

Thanks I found an old thread with a similar question.

http://www.ninjatrader.com/support/forum/showthread.php?t=50261

I also found this example, if anyone else ever ask the questions. I should be able to tie events to a GET/SET which is what I want, example below.

public class MyClass 
{ 
  private int _myHeight; 
  public event EventHandler Changed;

  protected void OnChanged() {
    if (Changed != null) Changed(this, EventArgs.Empty);
  }

  public int myHeight 
  { 
    get { return myHeight; } 
    set {
      myHeight = value; 
      OnChanged();
    } 
  }
  // Repeat the same pattern for all other properties
}

However is it possible at all to set these?
[Browsable(true)] - this is default
[Browsable(somevariable)] - can I use a variable?

I assume OnStartUp() occurs when the strat is enabled?

Hello happypappy,

Thank you for your response.

It would not be possible to set the bool for browsable. The OnStartUp() method is called when the strategy is enabled.

Wow man perfect thank you, Ill take a look Ill get it to set and see if I can make it refresh and remove them based on the selection, cheers again. Ill post the code here since it seems to be an ongoing issue.

Wow man this is a heap of code for such a simple function. Never the less it's been a question asked consistently. This code is from the link provided below by Baruch, I made changed to get my hidden functionality to work. I've got to split this into a few posts, I've attached the images and a few core functions here.

I've uploaded my test start, Ill break down the code into chunks. You add this to the top of the strategy.

Add this function to your class, I couldn't get the UpdateDisplayName to work but it was listed in the code I got from the link so it may be useful for someone.

In the Properties section, the name of the variable is the targeted properties name, so MyInput0 or Start in this case. You need [RefreshProperties(RefreshProperties.All)] next to the properties that control the actions.

The rest of the code is far to much to post, download the ZIP file and grab the 3 regions. Like from the picture attached.

Copy and paste this entire section, this creates the event handlers references at the top, and associates it to the function we added at the start. I really hope this helps a few people

Nice. One quibble. Your UpdateHiddenStatus() method will toggle every boolean attribute of the property it handles. You might want to make the method more restrictive to the particular attributes.
