Creating a Dropdown Control

Scenario

You want to draw and configure the dropdown command control that allows you to set the Alarm Value property to Active or Inactive from within your graphic.

There are two methods of doing this:

• You can gather object type information for a data point and then draw and configure a customized command symbol or graphical element, such as a button, that allows you to send commands from within a graphic.
• You can drag an existing default command symbol from a project library to a graphic. To add a default command symbol from a project library, proceed directly to Designating and Adding a Default Command Symbol to a Graphic.

Additionally,

• For overall background information, see Command Control Configuration.
• For Command Control and Navigation properties background information, see Command Control Properties and Command and Navigation Properties.
• For symbols background support when creating command control symbols, see Symbol Property Substitution.
