Adding a custom property in DataSeries grid for a new Bar Type

[rforteza]

Hi,

I would like to add a new property for a custom Bar Type of my own.

Please give a sample code for say a new boolean property using the standard bolean type converter.

The result will be to have a new Check Box inserted into the Data Series grid.

Thanks

Hello rforteza,

In general it would only be possible to use the existing inherited variables Value and Value2. This may be possible by creating a custom PropertyDescriptor, however this is not something that would be documented or that we would have samples for. PropertyDescriptor's are a C# concept, you can find an example of one in the following public link: https://stackoverflow.com/q/11892064 This is not something I am aware has been done, so this would certainly need tested and explored if this is something you wanted to do.

A BarsType is not as simple as an Indicator where only a public property is needed. In a BarsType, this works with properties collection directly.

Generally it is suggested to modify one of the existing inherited properties like the other BarsTypes do, however there are no bool inherited properties you can use. You would instead use a value like 0 and 1 to denote false and true.

The PointAndFigure is a good example of using the existing properties, you can see how this is done in its code:

SetPropertyName("Value",    Custom.Resource.NinjaScriptBarsTypePointAndFigureBoxSize);
SetPropertyName("Value2",    Custom.Resource.NinjaScriptBarsTypePointAndFigureReversal);

Value and Value2 are generic properties which can be used for any purpose your BarsType needs.


I look forward to being of further assistance.
