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 Microsoft .NET data types.

<RuleDesigner>
  <FieldBind>
        <Option />
        <DataSourceRef />
  </FieldBind>
</RuleDesigner>

Attributes

Attribute	Description
Name	String. The value displayed in the drop-down list box control.
TypeFilter	String. Used only if the parent FieldBind DesignerType is Operator. The TypeFilter attribute enables 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 FieldBind RuleDesigner type is Operator. The value that is specified in this attribute should be synchronized with the Field attribute of a FieldBind element. If this option is selected, the FieldBind specified here is 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 have 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 have 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	Specifies empty string.

示例

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

<RuleDesigner Sentence="%1">
   <FieldBind Field="MyParameter1" 
              Text="text" Id="1"       
              DesignerType="Operator" 
              OperatorTypeFrom="MyParameter1">
        <Option Name="equals" Value="Equal"/>
        <Option Name="not equals" Value="NotEqual"/>
        <Option Name="is greater than"

        <Option Name="is greater than or equal to"
