Prevalue Source Types Overview

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

Here is a quick overview of them:

  • 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 which Value field should be used for the value of the prevalue.

  • Select Use current page as root instead of choosing a specific root node. 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 List all Descendants of the selected root node to list all levels of descendants.

  • Select Order by from the drop-down list to display how the prevalue list should be ordered.

  • 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

    • Caption Column

  • Umbraco Data Type Prevalues

    • Choose an Umbraco Data Type to use its configured prevalue collection.
