A form can be used as an activity in a workflow subprocess to provide a user interface (UI) that works with a workflow task step.
Enable a form Submit button after operator interaction
You can ensure that the form's Submit button becomes active after an operator has entered data into the form. Using the IsSubmitEnable property prevents an operator from submitting a form prematurely because it does not contain data, or because the data is not valid.

    A form can be used as an activity in a workflow subprocess to provide a user interface (UI) that works with a workflow task step.
    - Extend the base form
    - Add pre-existing forms and user displays to Workflow
      This procedure is used for forms and user displays that were created outside of the Designer, in a tool such as Visual Studio.
    - Add custom submit, cancel, and enable to a form using the Designer
      The form can be configured so that the Workflow Task List Submit and Cancel buttons are not visible when the form is displayed in the Task List. You can also ensure that a form is only ready for submission after the appropriate operator interaction by enabling/disabling the Submit button.
    - Enable a form Submit button after operator interaction
      You can ensure that the form's Submit button becomes active after an operator has entered data into the form. Using the IsSubmitEnable property prevents an operator from submitting a form prematurely because it does not contain data, or because the data is not valid.
    - Declaring Parameters
      A form has input data that it processes into output data, even though it may not have a user interface. This section discusses the input and output parameters, which are passed to and from the client using the IForm interface.
    - Overriding the Base Form Methods
      Overrides are used to override the inputs and outputs of the base form and to allow you to pass inputs to and from a workflow into your form code.
    - Reading Data Internally
      In addition to input parameters, your form can have input data that is read internally; such as from a data source. This kind of data normally is received from a subscription to a Workflow service provider, and can be displayed in the form.
    - Writing Data Internally
      In addition to output parameters being used by Workflow to perform actions, your form can have output data that is written internally; for example, to a log file, or a Proficy service provider.
    - Subscribing to Events
      Your form can respond to published events.
    - Noting Form State
      Your form can note (to some extent) whether the Submit or Cancel button was clicked; such as to set the value of an output parameter.

Enable a form Submit button after operator interaction

You can ensure that the form's Submit button becomes active after an operator has entered data into the form. Using the IsSubmitEnable property prevents an operator from submitting a form prematurely because it does not contain data, or because the data is not valid.

Procedure

In either the Designer or Visual Studio:
1. Open or create an existing form.
2. From MainForm.xaml, open the MainPage.xaml.cs file.
In the code behind, add the following custom code: IsSubmitEnabled = false
The Submit button will now become enabled after the operator performs an action.
