Color as a parameter

[DaveS]

Hi.
I want to be able to set bar color from an input parameter. I have tried -

variables
private Color buyBarColor = Color.Blue;

Properties
[Description("Color for Buy Bars")]
[GridCategory("Parameters")]
public Color BuyBarColor
{
get { return buyBarColor; }
set { buyBarColor = value; }
}

I get a nice blue colored box in the indicator parameters section, and the
bars are colored blue by BarColor = BuyBarColor;. Any color can be chosen at this point but when Ninja is closed and re-opened, the blue setting (or whatever color was set) has been lost.
Is there any solution to this please?
Dave

Hello DaveS,

Thank you for your post.

There is a second segment of code that would need to be used for these to serialize property when saving your workspace.

Please try adding the following below your current code:

[Browsable(false)] 
public string BuyBarColorSerialize
{      
get { return NinjaTrader.Gui.Design.SerializableColor.ToString(buyBarColor); }      
set { buyBarColor = NinjaTrader.Gui.Design.SerializableColor.FromString(value); }

 }

Please see our Reference Sample on User Definable Color Inputs for more information:

Color as Parameter

Hallo, I' m sorry but this code doesn't work:
/// <summary>
/// </summary>
[XmlIgnore]
[Description("Select Color for TargetLineColor")]
[Category("Parameters")]
[Gui.Design.DisplayName("TargetLineColor")]
public Color TargetLineColor
{
get { return targetLineColor; }
set { targetLineColor = value; }
}

// Serialize Color object
[Browsable(false)]
public string TargetLineColorSerialize
{
get { returnNinjaTrader.Gui.Design.SerializableColor.ToS tring(targetLineColor);}
set { targetLineColor = NinjaTrader.Gui.Design.SerializableColor.FromStrin g(value); }
}

Thanks Rolf Theus

Hello RolfTheus,

Welcome to the NinjaTrader Support Forums!

I see a few formatting errors that may be causing issues.

}

Thanks Rolf Theus

There are a few spaces and one in need of a space that will be causing issues. You may see the following code below:

		[XmlIgnore]
		[Description("Select Color for TargetLineColor")]
		[Category("Parameters")]
		[Gui.Design.DisplayName("TargetLineColor")]
		public Color TargetLineColor
		{
		get { return targetLineColor; }
		set { targetLineColor = value; }
		}

		// Serialize Color object
		[Browsable(false)]
		public string TargetLineColorSerialize
		{
		get { return NinjaTrader.Gui.Design.SerializableColor.ToString(targetLineColor);} 
		set { targetLineColor = NinjaTrader.Gui.Design.SerializableColor.FromString(value); }
		}

Coding is very case and format sensitive, you may view the following link from our Help Guide that goes over some tutorials and concepts at the following link.

Let us know if we can be of further assistance.

Thank you for answering, but the spaces are product of copying. I tried to format the code in the Messagearea. I could compile my code. I have copied your code, and now it works fine. But what is the difference except the spaces ? I don't know.

Thanks

Hello RolfTheus,

I did not change anything inside the code that you posted besides add a space between "return" and "NinjaTrader.Gui(...)", remove the space between the "ToS" and "tring" in the same line, and remove the space between "FromStrin" and "g" in the next line.
