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: http://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.
