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:

  • Value Column

  • Caption Column
