Parameters

connectionId

Type: ContentStudioConnectionId
A value that identifies the web site

sessionId

Type: ContentStudio.SecuritySessionId
A value that identifies the user's session. This value usually originates from a call to OpenSession(ConnectionId).

categoryId

Type: ContentStudio.DocumentCategoryId
The category to save

documentType

Type: ContentStudio.DocumentDocumentTypes
The document type of the category. Document types can be saved but this is generally not recommended. If you set the document type to None the document type will not be changed.

searchable

Type: SystemBoolean
Indicates that the category can be used in unit-wide full-text search operations.

useServersideValidation

Type: SystemBoolean
Set this parameter to true to use the built in server side validation of EPT-data.

startDocumentId

Type: ContentStudio.DocumentDocumentId
The document that is used as start document of the Category. This parameter can be zero to remove the start document or -1 to ignore updates of this value.

defaultTemplateId

Type: ContentStudio.DocumentDocumentId
This is the template document that acts as the default template of the category. This must be an existing document template document. This parameter can be zero to remove the default template or -1 to ignore updates of this value.

bodyProperties

Type: SystemString
Data that will be placed in the body tag of the containing documents. The parameter cannot exceed MAX_BODYPROPERTIES_SIZE characters in length but can be null to ignore updates of this data.

description

Type: SystemString
A short string description of the category. This parameter cannot exceed MAX_DESCRIPTION_SIZE characters in length.

useMetaSecurity

Type: ContentStudio.DocumentCategoryManagerUseMetaSecurity
Set to true to use meta data security with this category. False turns off this functionality

editTemplateId

Type: ContentStudio.DocumentDocumentId
If the document is an ept-document then you can set this to an edit template document id. Otherwise set to 0.

customViewUrl

Type: SystemString
Defines a custom view to use in cs-admin

maxContentSize

Type: SystemNullableInt32
Defines (in bytes) the maximum allowed content size of a document, zero indicates no limit. Pass null to keep the current value. This parameter cannot be negative.

allowedFileTypes

Type: SystemString
Defines an array of file extensions that can be used for documents in this category. The file extension must start with a period (.). Use the value *. to allow any file extension. If any of the entries contains .* all other items will be discarded. This parameter can be null (Nothing in Visual Basic) to keep the current value. This parameter cannot be an empty array and at least one array member must contain a valid file extension or be empty. Internally this array is joined to a comma delimited string of file extensions and the size of this internal value cannot exceed MAX_ALLOWED_FILETYPES_SIZE number of characters, thus always keep in mind the extra comma added to each file extension when checking the text length of all elements in the array.
For categories that stores EPT documents, this value is always set to a hard coded value since only the .xml and .ept extensions are allowed.

namingConvention

Type: ContentStudio.DocumentFolderBaseDocumentFileNamingConvention
Tells how CS should name the file name for documents in the category.
