Welcome to the documentation for Microsoft Dynamics 365 for Operations on docs.microsoft.com. We are migrating our content here from the Dynamics 365 for Operations Help Wiki.
This article provides information that will help you select the best form pattern for the forms that you migrate.
The selection of a form pattern is an important step in the process of migrating a form. A pattern that is a good fit for the target form reduces the amount of migration work that is required. By contrast, a pattern that isn't a good fit can cause wasted time and effort. Therefore, it's important that you do some investigation, so that you can select the best form pattern for the form that you're migrating. Here is some guidance and tips for determining the appropriate pattern for a form:
- Investigate the form’s metadata in the form designer. Pay close attention to the following details:
- Form name
- Control names
- The way that the controls are organized
- The number and names of the data sources
- Investigate the form’s visuals by running the form and looking at the way information is displayed.
Selecting a form pattern via metadata
Use Form.Design.Style for guidance
The Form.Design.Style property often contains the name of the pattern that was previously targeted for the form. If the Style property correctly matches the metadata, you can use the following table to find a pattern that is likely to be a good fit for the form.
|Form.Design.Style value||Corresponding pattern|
|FormPart, where there are just fields||Form Part FactBox Card|
|FormPart, where there is a grid||Form Part FactBox Grid|
|SimpleListDetails, where there are 2–3 fields in the navigation list (recommended)||Simple List Details – List Grid|
|SimpleListDetails, where there are and 4–5 fields in the navigation list||Simple List Details – Tabular Grid|
|SimpleListDetails, where there is a tree (rare)||Simple List Details – Tree|
|TableOfContents||Table of Contents|
|Auto, where there is an Overview tab, a General tab, and a single data source||Task Single|
|Auto, where there are two sets of Overview tabs, General tabs, and/or headers plus lines||Task Double|
|Auto, where there is focus on a single record||Simple Details|
|Auto, where the form name ends in “Lookup”||Lookup|
|Auto, where there is a single tab control and Next/Previous buttons||Wizard|
|Auto, where the form name ends in “Wizard”||Wizard|
|Auto, where there is just a grid and some buttons||Simple List|
When a form doesn't match the Style property
Sometimes, a form has an incorrect Form.Design.Style property value.
|Form.Design.Style value||What the form might actually be|
|DetailsFormMaster||DetailsFormTransaction, if there is lines detail, or if controls have names that contain “lines"|
|SimpleList||SimpleListDetails, if there is more than just a grid and some custom filter fields|
|SimpleListDetails||SimpleList, if there is just a grid and some custom filter fields|
|SimpleList||ListPage, if there are numerous FactBoxes in the Parts node, or if the form has a corresponding Details Form|
Selecting a form pattern via visuals
Although this approach is less useful than looking at the form metadata, you can get a lot of information about a form by running and examining it. Use the form visuals as an additional data point to help you select a form pattern. Look through the screen shots of migrated forms to find a form that looks like the target form. Additionally, make sure that the description or intent of the pattern matches the description/intent of the form.

Finding forms that currently use a particular form pattern
For a full list of forms that are currently using a particular form pattern, generate the Form Patterns report from within Microsoft Visual Studio. On the Dynamics 365 menu, expand the Add-ins option, and click Run form patterns report. A background process generates the report. After several seconds, a message box appears in Visual Studio to indicate that the report has been generated and inform you about the location of the Form Patterns report file. You can filter this file by pattern to find forms that use a particular pattern.
Form pattern visuals and descriptions
For each form pattern class, information is provided about each variant. This information includes a short description and an illustration of an example form.
Details Master[Default] This form pattern is used to display the details of a complex entity on FastTabs. It includes a grid view and a details view.
Details Master w/ Standard Tabs Use this Details Master variant when your form has a large number of FastTabs (>15) that can be grouped into categories.
Details Transaction Use this form patter to show the details of a complex transaction entity and its lines (for example, an order and its lines).
Dialog – Basic[Default] This form pattern is used to gather or show a set of information.
Dialog – Read Only Use this Dialog variant when your Dialog just displays information that can't be edited. It has only a Close button.
Dialog – FastTabs Use this Dialog variant when your Dialog content is grouped into FastTabs.
None currently in product.
Dialog – Tabs Use this Dialog variant when your Dialog content must be grouped into tabs.
Dialog – Double Tabs Use this Dialog variant when your Dialog content has two tabs that are stacked on top of each other.
Drop Dialog[Default] This form pattern is used to initiate actions when the number of fields is small (less than five).
Drop Dialog – Read Only Use this Drop Dialog variant when the fields in the Drop Dialog aren't editable. No OK/Close button is modeled.
No example currently exists in the product.

Finding containers that require that a subpattern be applied on a form
When a form is open in the Visual Studio designer, you can easily search for containers that must still have subpatterns applied by searching for “unspecified” in the control search box at the top of the designer (as shown in the following screen shot).
