When working with Web Page Dashlets in the Dashboard Designer, you can include a parameter reference in the Dashlet's URL. The parameter references an existing filter in another Dashlet and uses that filter to display a specific web page relevant to the filtered information.
The following example takes you through the steps for creating a simple Dashboard in the Dashboard Designer, adding a sample chart with geographic filters, and creating a Web Page Dashlet that displays a Wikipedia page for the country the sample chart is filtered on.
First, create the simple dashboard:
- From the Home page. Click Create > Dashboard. The Dashboard Designer appears, displaying the list of available content and the canvas.
- In the Existing Content section of the Available Content panel, find and select a Report.
- Click and drag the Report onto the Dashboard Canvas.
- Next, add the Filter input control to the Dashboard:
- In the Filters section, expand the folder.
- Drag the Customer Country input control onto the canvas.
Now, add the Web Page Dashlet with the parameter reference and add it to the filter:
- In the New Content section of the Available Content panel, click and drag the Web Page item onto your Dashboard. The Dashlet URL window opens.
- Enter the following URL: https://en.wikipedia.org/wiki/$P\{Customer Country}
- Click the OK button.
- Right-click the Dashlet and select Properties from the context menu.
- Change the Dashlet Name to "Wiki."
- Click the Parameter Mapping icon to open the Parameter Mapping window.
- Open a row containing the new Affected Dashlet and Filter/Parameter dropdown menus that appear.
- In the Dashlet Affected column, select "wiki" from the new Select dashlet dropdown menu.
- In the Filter/Parameter Affected column, select a field from the new Select parameter dropdown menu.
- Click the OK button.
Finally, preview the new Dashboard functionality:
- Preview the Dashboard.
- Click in the text box to display the available values.
- Select a value from the values list, and click the Apply button at the bottom of the Dashlet.
- Return to the Dashboard Designer.
- Select Save Dashboard.
- In the Save As window, change the default name and locate a folder, such as the /Dashboards folder.
- Click Save.
