Adding a Drop-down control
Use the Dropdown control to display a list of options, from which the user can select a single option. The list of options can be defined in a list bound to a property, or a clipboard page, a data page, or a report definition.
When the source is a clipboard page, data page, or a report definition, you can categorize items within the drop-down list.
When a drop-down list is bound to a data page or report definition that accepts parameters and the parameter value uses a property reference, the drop-down list automatically refreshes with new items whenever the property value changes. No additional configuration is required. This can be used to set up cascading drop-down menus or any combination of controls.
You can style the drop-down control in your application skin; see Skin form — Components tab — Controls — Dropdowns.
Upgrading to use the pxDropdown control
The Dropdown control in the Pickers list replaces the deprecated Select control. As a best practice, upgrade PromptSelect and DynamicSelect controls to drop-down controls.
If a section contains PromptSelect, DynamicSelect, or another control for which there is an improved alternative, a warning displays, along with an Update Controls button. Click Update Controls to automatically update deprecated controls in the section.
