Specifying the data source for a Timeline control
To identify the events to display on the timeline, you specify the data source — property or data page — for the events. At run time, the list is automatically refreshed with new items whenever the property or data page value changes.
-
In the Source field on the General tab of the Properties panel, specify the data source for the control:
Property
-
Select this option and in the corresponding List field, press the Down Arrow key to select the property to use as the source of the events.
Data page
-
Select this option and in the corresponding Data page field, press the Down Arrow key to select the data page to use as the source of the events.
-
If the data page has parameters, press the Down Arrow key in the Value fields to specify the values that you want to pass to the data page.
-
-
Set the Visibility option to determine when the timeline is displayed.
-
Select Always to display the timeline unconditionally.
-
Select Condition (expression) to make the visibility dependent on an expression. In the field that is displayed, select a condition or click the Open condition builder icon to open the Condition Builder.
-
Select Condition (when rule) to make the visibility dependent on a when condition rule. Click the Open icon to create a when condition or review an existing one.
-
If you selected an expression or a When rule, select the Reserve space when hidden check box to reserve space on the screen when the timeline is hidden.
