The data quality code for any tag bindings on this component.ДЄ comma separated list of columns to hide from the dropdown table, eg. Either a 1 or 2 column DataSet, with the first column being the value, and the second being the display The mouse cursor to use when hovering over this component. NOTE that the border is unaffected by rotation. This value will be set as the dropdown's Selected Label.Дraw with antialias on? Makes text smoother. The same selection rules as defined by Lenient mode, except that the dropdown itself becomes editable, allowing a user to type in their own arbitrary value. If the current selection is not present in the Data list, the read-only property Selected Index will be -1. This mode is useful to avoid race conditions that can cause problems in Strict mode when both the Data and the Selected Value properties are bound. (default) Selected values are independent of the list defined by the Data property. If the Data property is set to a list that does not contain the current selection, the current selection will be reset to the No Selection values. If an invalid selection is set (via a binding or a script), the selection will be set to the values defined by the No Selection properties. Selected values must always correlate to an option in the list defined by the Data property. These modes affect how the dropdown's current selection (defined by the values of its Selected Value, Selected String Value, and Selected Label properties) behave when the selection properties are set to values not present in the choice list, or conversely, when the choice list is set to a new dataset that doesn't contain the current selection: The dropdown component can operate in one of three Selection Modes.

Selected Label represents value from second column.

Selected String Value represents value from first column.

Dropdown displays values from second column.

Scenario 1: One column with a set of string values The 3 ways to set up the data dataset and the corresponding behavior is as follows: The data property can be set up in one of three fashions, which control how the 'selected values' properties change.

The dropdown component is perfect for such a use. So, for instance, when the user chooses 'Other' you really want to get the number 3.

But, you really want to map these choices to some numeric code which is how the choice is stored. The choices might be: 'Operator Error', 'Machine Malfunction', and 'Other'. For instance, suppose that you are selecting choices for a downtime tracking entry. It is often the case that you want to display choices to the user that are 'dressed up' versions of the actual choices. This is a dataset, which can be typed in manually in the Designer, or (more commonly) it can be populated dynamically from a property binding, often a SQL Query binding. The choices that are shown depend on the data property. The current selection is shown, and the choices are only presented when the user clicks on the dropdown button. The dropdown component is a great way to display a list of choices in a limited amount of space.
