The dialog is displayed when you click the button 
while specifying parameter values. It helps you to specify multiple values for a parameter. See the dialog.
Available Values
Lists all predefined parameter values for selection. When the parameter is bound with a column, but the Display Column is different from the Bind Column, values of the Display Column are listed here.
Selected Values
Lists the values selected. The selected values are case sensitive.
Adds the selected values from the Available Values box to the Selected Values box.
Removes the selected values from the Selected Values box.
Adds all the selected values from the Available Values box to the Selected Values box.
Removes all the selected values from the Selected Values box.
Enter Values
This option is available when the parameter's Allow Type-in of Value was set to true while it was created in JReport Designer.
Enter a value manually in the text box and then click the button next to add the value to the Selected Values box. When the parameter is bound with a column, but the display column is different from the bind column, make sure the value you enter is that of the bind column.
All
If selected, it means that the parameter value result is all the values in the DBMS. This option is available when the parameter's Enable the "All" Option was set to true while it was created in JReport Designer. This is translated in SQL to remove the parameter which may select more values than listed in the available values list.
For example, when the parameter query is:
SELECT CUSTOMERS.CUSTOMERID,CUSTOMERS.CUSTOMERNAME FROM CUSTOMERS where CUSTOMERS.CUSTOMERID>0 and CUSTOMERS.CUSTOMERID<4
When you click to add 1, 2 and 3 as the parameter values, which are all the available values, the SQL is:
(CUSTOMERS.CUSTOMERID IN ( 1,2,3))
Run the same report again and this time check the All checkbox in the Enter Values dialog, the query is then:
( 1 = 1)
In this case, you will get more customers even though available values are only 1 – 3.
Note: When a multi-value parameter is inserted as a field into a report and All is selected as the value, the field will show the string "All" which represents all the values in the DBMS.
OK
Applies the selected values to the parameter and closes the dialog.
Cancel
Does not retain any changes and closes the dialog.
