When designing input controls for a dashboard, keep these guidelines in mind:
|•||Consider the ramifications of designing input controls to use radio buttons. A report’s input control that displays as a radio button set appears as drop-down on a dashboard.|
|•||To pass a value to an external URL, the URL Parameter Name you give to the input control must match the name of a parameter that the URL can accept. The value of the input control must also be a value the URL can accept. The target URL is likely to have additional requirements and limitations. For example, the name of the parameter may be case-sensitive; in this case, the value you enter in the URL Parameter Name field is also case-sensitive. This is the case for Bing’s q parameter that is referenced in Adding a Custom URL to a Dashboard.|
The input control must pass data that the URL can accept. Otherwise, the server may be unable to retrieve the correct data from the external URL.
