Applying Web Actions to a Label

A label in a page report that is created using query resources or in a library component can be bound with web actions. This allows you to customize a label to make it respond to interactive events, and execute corresponding actions such as sorting and filtering. For example, you can insert a label in Logi JReport Designer and associate an action with the label's onclick event. Then at runtime when end users run the report and select the label, the defined operation will be executed.

The following table lists the events that can be used to trigger web actions:

To bind web actions to a label:

1. Right-click the label and select Display Type from the shortcut menu.
2. In the Web Behaviors box of the Display Type dialog, choose an event from the Events column, then select in the Actions column and select that appears in the text box.
3. In the Web Action List dialog, select the required action and then select OK.

   

   • If the selected web action is Filter, Sort, Parameter, Property, SendMessage or Customized Control, the corresponding web action builder dialog appears. Specify the settings according to your requirements.
   • If Customized Control from Lib is selected, the Customized Control Manager dialog is displayed, which shows all the customized control files in the customized control library. Select the one you want and select OK.
   • If the selected action needs no parameter, the Web Action List dialog is closed.
   • If the selected web action needs parameters, the Parameters dialog appears for you to input the parameter values. For parameters that refer to instance name, you can input the mapping name of the instance, or the display name plus the prefix "&" as the parameter value.
4. Select in the Display Type dialog and repeat the above steps to add more web actions. If a web action is not required, select to remove it.
5. Adjust the order of the added web actions by selecting or . Then, when an event that has been bound with more than one action happens, the upper action will be triggered first.
6. Select OK to apply the settings and close the Display Type dialog.

Then, at runtime, when any of the specified events occurs on the label, the web action defined on the event will be triggered.
