Prerequisite
For the purpose of testing, I had this data set of CustGroup. This can also be found on Legal Entity USRT of demo data comes with a new environment of Dynamics 365 Finance.
| Customer group | Description |
|---|---|
| 10 | Wholesale customers |
| 20 | Major customers |
| 30 | Retail customers |
| 40 | Internet customers |
| 50 | Employees |
| 80 | Wholesale customers |
| 90 | Wholesale customers |
I added two new buttons on CustGroup form:
Bulk update Desc: This button will loop through each and all records in the above table and update the Description to Description ++ Updatedexcept one containing "Employee". They will become like below.
| Customer group | Description |
|---|---|
| 10 | Wholesale customers + Updated |
| 20 | Major customers + Updated |
| 30 | Retail customers + Updated |
| 40 | Internet customers + Updated |
| 50 | Employees |
| 80 | Wholesale customers + Updated |
| 90 | Wholesale customers + Updated |
Reverse Bulk update Desc: This button will update all Description back to its original by removing the word+ Updated.

In the extension class named CustGroup_ButtonHandlers, I put these codes which will handle the event of clicking those two buttons.
tip
This type of FormControlEventHandler will only be needed when you are extending a standard form. For a totally custom form, you can add a Clicked() method method for any buttons on the form.
