Hi Mark,

Arthur is right.

You need to reset the object to the Ribbonbar control. You can refer to the code below:

RibbonCategoryItem lr_Category

rbb_1.GetItemByTag ("CategoryOrderTest", lr_Category)

lr_Category.visible = false

rbb_1.setcategory(lr_Category.itemhandle , lr_Category)

 

Following are the related documents for your references.

The RibbonBar control is a container. The RibbonBar control, as well as the item controls it contains, have a hierarchical relationship. The item controls cannot exist independently and must be placed on top of the parent object; therefore, to get an item control, you need to search from the top level (RibbonBar control), or to search by tag. The control you get is a copy (not a reference), and after the copy is modified, it needs to be set back to the parent object, and then to the RibbonBar control, for the change to take effect.

Hi 

you have to set it as well.

RibbonCategoryItem lr_Category
rbb_1.GetItemByTag ("CategoryOrderTest", ref lr_Category)
lr_Category.visible = false

rbb_1.SetItem( lr_Category )
