Referencing the Value

@fieldname@

@fieldname.combovalue@

or

@#fieldid#@

@#fieldid.combovalue#@

When trying to reference the values of this custom field type, you must use @fieldname@ or @fieldname.combovalue@, depending on how the field is setup. Typically, you can use @fieldname@ but there is a special case where you must use @fieldname.combovalue@ when the values in the combo box are 1=Yes;2=No;3=Maybe.

Using @fieldname@ will return the Yes, No, or Maybe. But using @fieldname.combovalue@ will return 1, 2, or 3.

Using @fieldname.value@ will display the full HTML of the field; in other words, a dropdown box containing the values of the field will be displayed.

Notes

The best practice when creating a combo box with a --Select One--is to use store-value=display-value syntax with a space as the stored value:

 =--Select One--;Option 1;Option 2;Option 3;Option 4

This ensures that the database won't store the value "--Select One--" which may cause security issues based on specific security settings.

If you want the value stored in a Dropdown List field to be different from what is displayed in the combo box, you can use the following syntax in the Values section of the custom field settings:

StoreValue1=DisplayValue1;StoreValue2=DisplayValue2;StoreValue3=DisplayValue3;

• The value before the equals sign, known as the stored value, will be stored.
• The value after the equals sign, known as the display value, is what will be displayed in the combo box (or check boxes), but does not get saved.

By default, the stored value is shown when fields are referenced in List Views. Selecting the Show Display Value in List Views option in the custom field settings will display the display value.

• The first value listed will be the default value when a new record is created.
• This technique is important when translating to other languages. The StoreValue must be the same in all languages. See here for further information.

Allow Empty

Because the values in a Combo Box Custom Field are restricted to the semi-colon delimited list in the Values field, the Allow Empty field has a slightly different behaviour than usual. It controls whether or not the record can be saved with the default value (which is the first value listed in the Values section):

• If Allow Empty is checked, the record can be saved with the default value.
• If Allow Empty is not checked, the record cannot be saved with the default value. In this way you can force the user to select a value different from the default value.
• Important: Because the record cannot be saved with the default value, the first item listed in the Value section should be either a space followed by a semi-colon (if you want the field to start out blank) or an instruction to the user such as -----Select One-----; Please choose; or similar. You do not want an actual value as the first item, since the record can never be saved with the first value if Allow Empty is deselected.

Retired Options

If you need to hide options which are no longer being used but need to be retained for historical value, you can use the following syntax:

<ssRetiredOptions> </ssRetiredOptions>

Make sure there are semi-colons before and after the syntax.

Example: 1;2;3;<ssRetiredOptions>5;6</ssRetiredOptions>;7;8

When using this method, the retired options must not be the first options in the list. If the first option(s) in the list are to be retired, simply move them to the end of the list so that Option1;Option2;Option3 becomes Option2;Option3;<ssRetiredOptions>Option1</ssRetiredOptions>;
