Option Element (WorkflowActions)
This content is outdated and is no longer being maintained. It is provided as a courtesy for individuals who are still using these technologies. This page may contain URLs that were valid when originally published, but now link to sites or pages that no longer exist.
Used to populate DesignerType drop-down list box controls that are not data bound. Option elements contain text and value pairs that can be used to build a workflow sentence. They also contain information about their .NET data types.

Attributes
Attribute |
Description |
|---|---|
Name |
String. The value displayed in the drop-down list box control. |
TypeFilter |
String. Used only if the parent FieldBindDesignerType is Operator. The TypeFilter attribute allows options to be hidden or displayed in the workflow editor, based on the data type of the parent element. You can define multiple types for the TypeFilter attribute but they must be separated by commas. |
UnaryHides |
String. Used only if the parent FieldBindRuleDesigner type is Operator. The value specified in this attribute should be synchronized with the Field attribute of a FieldBind element. If this option is selected, then the FieldBind specified here will be hidden from the workflow editor. |
Value |
String. Represents the value of the selected drop-down list item. |
Value Attribute
The following table contains attribute values that are used with a TypeFilter attribute of Operator that performs conditional comparisons. Custom values can be substituted.
Value |
Description |
|---|---|
Equal |
Returns true if queried values are equal. Case sensitivity must match. |
EqualNoCase |
Returns true if queried values are equal. Case sensitivity does not need to match. |
NotEqual |
Returns true if queried values are not equal. Case sensitivity must match. |
NotEqualNoCase |
Returns true if queried values are not equal. Case sensitivity does not need to match. |
StartsWith |
Returns true if queried values start with a specific pattern. |
NotStartsWith |
Returns true if queried values do not start with a specific pattern. |
EndsWith |
Returns true if queried values end with a specific pattern. |
NotEndsWith |
Returns true if queried values do not end with a specific pattern. |
Contains |
Returns true if queried values contain the specified pattern. |
NotContains |
Returns true if queried values do not contain the specified pattern. |
ContainsNoCase |
Returns true if queried values contain the specified pattern. |
Matches |
Returns true if queried values match a specified regular expression. |
IsEmpty |

Example
The following XML demonstrates how to construct an Option element so that it is visible to the workflow designer.
