Enable/Disable Ribbon Buttons using Named Expressions?

Jan, Jon and Rod (others) are the best, aren't they? Correct you for forum etiquette, yet you still get the help you need. Too bad Bentley doesn't roll this way. I remember when they did.

Thanks Rod,

Will try this and revert back if i have any doubts.

Regrads,

If you want an example of how this is done, download our freeware macros from here.
https://envisioncad.com/freeware/microstation-resources/

After following the install instructions you will have an EnvisionCAD_gui.dgnlib file that contains custom toolboxes, ribbons, and associated Named Expressions.

If you open the dgnlib file and open the Named Expressions dialog you will see these custom assignments.

In the Customize dialog if you open the associated toolbox button you will see how the Named Expression is utilized.

Finally, if you open the EnvisionCAD_Freeware_CONNECT.cfg file in Notepad you will see the variable assignments.

Toggling those variable values between 0 and 1 will turn off/on the display of the toolbox and ribbon buttons.

I need to enable /disable ribbon menu buttons based on a variable value. When i searched in community, many suggestions was can be done through "Named Expressions".

Yours isn't a programming question.  A better place to post it would be the Administration Forum or the MicroStation Forum.

Named Expressions are discussed in MicroStation Help. 

You can use named expressions with the Customize utility to:

• define conditions under which when a tool or task is shown or hidden.
• define conditions under which a menu or menu item is shown or hidden and enabled or disabled.
• define conditions under which a menu item is marked.
• define conditions under which a contextual menu item is shown or hidden and enabled or disabled.
