Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)
Syntax 
public void SetCategoryHidden(
	ElementId categoryId,
	bool hide
)

Parameters

categoryId ElementId
The ID of the category.
hide Boolean
True to make elements of this category invisible, false to make them visible.
Exceptions
Exception Condition
ArgumentException categoryId does not correspond to a Category. -or- Category cannot be hidden.

Remarks
This affects only if the category is set visible or invisible individually. Other Revit mechanisms may also affect the visibility of elements of this category, including:
  • The category classes settings for model categories, annotation categories, import categories or analytical model categories.
  • View filters.
  • Elements hidden individually in the view.
Thus setting this value may not affect the actual visibility of elements of this category in the view.
