  1. HI Mani,

    I need to validate a field called 'Project name' which gets created by workflow.
    This field is combination of three columns.

    I need to validate if this name already exists in the list.

    Please help

    1. Hi,

      Generally using SPUtility you can access fields which are available on the form (New/Edit), for more details about SPUtility, pls go to

      If you want to check whether particular field exists in the list then you have to go with SharePoint Client Object Model.


  2. Can I make field required only when user clicks on rejected button on a task form?

    Thanks in advance
