NinjaScriptProperty - Not working as expected...

[benjamin$]

Hello,

I recently built an indicator with 21 NinjaScriptProperty's and under the "Display" attribute each has been given a separate "Order" variable starting with 1 and ending with 21. They are then grouped together in sets of 3 using the "GroupName" variable beginning with "Line One" and ending with "Line Seven."

By doing this I expect to see them listed in the GUI with Line One at the top and Line Seven at the bottom but instead they are listed in alphabetical order according to their "GroupName." So they appear in the following order:

Line Five
Line Four
Line One
Line Seven
Line Six
Line Three
Line Two

Is this the expected behavior for the "Order" and "GroupName" variables?

Here is a copy and paste of the first two sets of property's:

// Property Settings...
#region Properties

// Line one properties...
[NinjaScriptProperty]
[Display(Name="Time Frame", Description="Line One's time frame parameter.", Order=1, GroupName="Line One: ")]
public CandleSelection.Time TimeFrameOne
{
get { return timeFrameOne; }
set { timeFrameOne = value; }
}

[NinjaScriptProperty]
[Display(Name="Candle Position", Description="Line One's position parameter.", Order=2, GroupName="Line One: ")]
public CandleSelection.Position CandlePositionOne
{
get { return candlePositionOne; }
set { candlePositionOne = value; }
}

[NinjaScriptProperty]
[Display(Name="Bars Ago (0 is current bar)", Description="Line One's historical bars parameter.", Order=3, GroupName="Line One: ")]
public int BarsLookBackOne
{
get { return barsLookBackOne; }
set { barsLookBackOne = value; }
}

// Line two properties...
[NinjaScriptProperty]
[Display(Name="Time Frame", Description="Line Two's time frame parameter.", Order=4, GroupName="Line Two: ")]
public CandleSelection.Time TimeFrameTwo
{
get { return timeFrameTwo; }
set { timeFrameTwo = value; }
}

[NinjaScriptProperty]
[Display(Name="Candle Position", Description="Line Two's position parameter.", Order=5, GroupName="Line Two: ")]
public CandleSelection.Position CandlePositionTwo
{
get { return candlePositionTwo; }
set { candlePositionTwo = value; }
}

[NinjaScriptProperty]
[Display(Name="Bars Ago (0 is current bar)", Description="Line Two's historical bars parameter.", Order=6, GroupName="Line Two: ")]
public int BarsLookBackTwo
{
get { return barsLookBackTwo; }
set { barsLookBackTwo = value; }
}

It continues like this for all seven lines...

Thank you for your help! NT provides EXCELLENT service on these forums.

Hi Ben, thanks for writing in. We use an open-source property grid manager to make this control. By default, the categorized properties are listed alphabetically. The most straightforward solution is to add alphanumerically order labels e.g. GroupName="1. Line One: " GroupName="2. Line Two: ". There may be a way to change this, but you would need to look through the Wiki for this tool to see if that would be possible:

Thank you, I'll give it a look!

benjamin$ This should do what you want: https://ninjatrader.com/support/help...rattribute.htm

For example:

    [Gui.CategoryOrder(XXGroupName, 0)]   // XXGroupName is just a string with a group name in it, starting with, e.g., the letter X
    [Gui.CategoryOrder(AAGroupName, 1)]   // AAGroupName is just a string with a group name in it, starting with, e.g., the letter A

The XX group will be listed first, then the AA group. You don't need to use string variables, but it does make it easier. You could just use string constants, if you prefer.

Thanks.

I was hopeful this would work but after implementing it as described I get an error (CA0592) that says, "Attribute 'Gui.CategoryOrder' is not valid on this declaration type. It is only valid on 'class, interface' declarations."

Seems like some room for improvement in this area since correct GUI order is kind of important.

Hi benjamin, you apply it to the class, not the properties. I attached my test script for reference. jeronymite thanks for finding that for us.
