GetCurrentSelections() returns a list of the current selections in the app. If the selections are instead made using a search string in a search box, GetCurrentSelections() returns the search string.
If options are used, you will need to specify record_sep. To specify a new line, set record_sep to chr(13)&chr(10).
If all but two, or all but one, values, are selected, the format 'NOT x,y' or 'NOT y' will be used respectively. If you select all values and the count of all values is greater than max_values, the text ALL will be returned.
Syntax:
GetCurrentSelections ([record_sep [, tag_sep [, value_sep [, max_values [, state_name]]]]])
Return data type: string
Arguments:
| Arguments | Description |
|---|---|
| record_sep | Separator to be put between field records. The default is <CR><LF> meaning a new line. |
| tag_sep | Separator to be put between the field name tag and the field values. The default is ': '. |
| value_sep | The separator to be put between field values. The default is ', '. |
| max_values | The maximum number of field values to be individually listed. When a larger number of values is selected, the format 'x of y values' will be used instead. The default is 6. |
| state_name |
The name of an alternate state that has been chosen for the specific visualization. If the state_name argument is used, only the selections associated with the specified state name are taken into account. For more information, see Using alternate states for comparative analysis. |
