Original Pull Request: https://github.com/radzenhq/radzen-blazor/pull/1696

State: closed
Merged: No

The issue:
On an app I have a dropdown component that uses RadzenDropdown and searchs on database for the options based on the Value type.
On a specific page of mass creation I have about 100 dropdowns that search on the dabase in generic ways, so it triggers about 100 SQL's in a very short time, what causes the database license to return an error for too many users.

The solution:
In order to not have to handle it manually every time I have this kind of scenario, I added a LoadDataOnOpen parameter to RadzenDropdown that basically does not trigger the LoadData on the dropdown initialization and runs it on the first time that the popup is oppened.

Also created a Demo for test on "/dropdown-load-data-on-open"
