Custom PropertyGridItemElement

[Piotr]

I created  ItemElementBlank class that is used for two separate types in the property editor. I want to display no text next to the property label. It works properly when properties are collapsed. When one of the properties are expanded seems that my display element is used in the wrong row ("Odstęp linii" instead of "Alarm"). I coloured the control to a yellow gradient for a better view.

Hello, Piotr,

According to the provided information, it is not quite clear what is the exact custom implementation that you have. Could you please elaborate?

However, I suppose that the IsCompatible method is not overridden in the custom PropertyGridItemElement.  In order to avoid reusing of the custom element for other items, you can override the PropertyGridItemElement.IsCompatible method and control whether the custom element is applicable for the specific PropertyGridItem . In addition, it is necessary to create another PropertyGridItemElement which is not compatible with your custom item. A sample approach is demonstrated in the following help article:

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
