When you create and modify parameter names, follow the rules below:

  • A name can contain letters, numbers, and underscores.

  • The dashboard cannot contain parameters with the same name.
  • Names are case-sensitive. For example, you can create the names Parameter and PARAMETER.

The following limitations apply to parameters with multi-selection enabled:

  • Use the Is any of or Is none of operators to pass a multi-select parameter to a filter criteria or to the Expression format condition.
  • Use the In or Not In operators to pass a multi-select parameter to a calculated field expression.
  • Custom SQL queries do not support multi-select parameters out of the box. For more information, refer to the following article: Use Query Parameters.
  • Stored procedures used in SQL and Entity Framework data sources do not support multi-select parameters out of the box. For more information, refer to the following article: Use Query Parameters.

The corresponding property: Parameter.allowMultiselect

Select All Values

Specifies whether all parameter values should be selected in the initial state of the dashboard.

Note that this option is in effect when the Allow Multiselect setting is enabled.
