Overview of the Prevalue Source Types

There are some default prevalue source types that can be used.

In Umbraco Forms version 8, for each prevalue source you setup, a json file will be generated in ~/App_Data/UmbracoForms/Data/prevaluesources.

Here is a quick overview of the default types:

• Get values from textfile

  Upload a textfile that contains the prevalues. Each prevalue should have its own line in the file. Once the file has been uploaded, you can find it in ~/wwwroot/App_Data/UmbracoForms/Data/PreValueTextFiles/{GUID} where the {GUID}is replaced with the pre-value ID.

• Umbraco Documents

  Allows to use content nodes from a specific source as prevalues. You can define the root node by either

  • Choosing a node directly from the Content tree or

  • Using XPath

    

    Additional settings can be applied:

    • Select Use current page as root instead of choosing a specific root node. Note that the preview is not available when this setting is enabled.
    • Select a specific Document type, if the selected root node contains a different document type.
    • Select to include Grand children of the selected root node.

• SQL Database

  Connect to a OleDB compatible database table and construct a prevalue source from it. Once selected, it will be editable from the Forms interface.

  The following configurations need to be set:

  • Connection string (either choose one from your web.config or add another from a textfield)
  • Connection String from configuration
  • Table Name
  • Key Column
  • Value Column

• Umbraco Data Type Prevalues

  Choose an Umbraco data type to use its configured prevalue collection.

  In the example below, the prevalue collection from a data type called Home - Font - Radio button is used:
