Modify a form

Applies To: Microsoft Dynamics AX 2012 R3, Microsoft Dynamics AX 2012 R2

Microsoft Dynamics AX for Retail POS introduces a new way to customize forms by using the Interaction service. This enables multiple developers to customize one or more forms in one service. If there are multiple customizations, the Interaction service loads only the first customization it finds for a form. The following list of forms use this new pattern and their implementations are included in the InteractionDefaults service.

• ExtendedLogOnForm

• ExtendedLogOnScanForm

• frmBarcodeSelect

• frmDimensions

• frmInput

• frmPayCash

• frmPayCurrency

• frmPayCustomerAccount

• frmReturnTransaction

• LogbookForm

• LogOnForm

• ManagerAccessForm

• RegisterTimeForm

• ViewTimeClockEntriesForm

• ProductDetailsForm

• ProductInformationForm

How to customize a form

You customize a form by overriding the form and then changing its functionality and its look and feel. In the following example, you customize the LogOnForm form and change the background color.

To customize an interaction form

1. In the folder where you installed the Retail POS SDK, open the Microsoft Dynamics AX for Retail POS Plug-ins folder. For more information on installing Retail POS Plug-ins, see Install the Retail SDK.

2. Open the Services folder and double-click the Services Visual Studio solution file.

3. Right-click the InteractionDefaults Visual Studio project name and rename the assembly.

   Warning

   When customizing Retail POS Plug-ins, it is recommended that you give the modified assemblies new names, so that the original assemblies remain available if you need to revert back to them.

4. In this step, you override the LogOnForm form, which has a dependency on the ManagerAccessForm. Remove the other forms from the InteractionDefaults project. This enables other users to override the excluded forms. override
