Hello guys. I have created an asp.net core application which in, I have used the RadZen dropdown. everything is ok and the component is rendered successfully but when the user clicks on the item and selects them, I am not able to get the selected values. Here is a brief of my code :

this is the razor file which the RadZen dropdown exists there.

here is also my .cshtml file which I have wrapped in the razor file in order to use it somewhere else.

I called it this way:

as you can see in this image, everything is ok 👍

but when I try to get Model.SelectedValues (that I have bonded it in the razor file) when the form is submitted. nothing there on the list.

I also read that the selected items data type and data list should have the same data type as well so I have changed the selected items data type, unfortunately, it did not work.

I am not sure if Blazor components support your scenario. You can try using the built-in InputSelect and see if it makes a difference. Also I see you have opened a forum thread as well - will close this issue as I don't think there is anything actionable on our side.
