How to pass a dashboard parameter to a filter string in code

The following example demonstrates how to create a new dashboard parameter and pass it to a dashboard item filter string.

In this example, the dashboard data source contains two queries - the SalesPerson query is used for data visualization while the Categories query provides values for the dashboard parameter.

After the dashboard parameter is created, it is passed to a dashboard item's filter strings. So, the dashboard displays data according to the selected values.
