I have two dropdowns. The second dropdown should change when a new option is selected in the first dropdown but it does not.

[Brian Collings]

I have two dropdowns on a razor page. 

The first displays financial periods and the second should display the financial years linked to the selected financial period.

However the second dropdown displays the financial years linked to the first financial period no matter what financial period is selected.

I cannot figure out why it isn't working.

I have attached the application, a backup of the database and a word document with more details of the problem.

I hope someone can help me fix this.

Based on the details provided, it seems that you are looking to configure cascading functionality in the ASP.NET Core Dropdown List Control. Unfortunately, we were unable to access the sample that you have shared as it requires a login to view the application page.

For detailed guidance on configuring cascading in the Dropdown List Control, you can refer to the documentation linked below. Additionally, the online demo will provide you with a practical example of how to implement this feature.
