RadzenDropDown Multiple

I am using the latest version 2.16.3
But the RadzenDropDown has problem when using Multiple="true" with @bind-Value= xxx where xxx is IEnumerable type.
Is it a bug of the library?

Below is the details of the error:
|Error|CS1503|Argument 2: cannot convert from 'Microsoft.AspNetCore.Components.EventCallback<System.Collections.Generic.IEnumerable>' to 'Microsoft.AspNetCore.Components.EventCallback'
|Error|CS0029|Cannot implicitly convert type 'System.Collections.Generic.IEnumerable' to 'string'
|Error|CS1662|Cannot convert lambda expression to intended delegate type because some of the return types in the block are not implicitly convertible to the delegate return type

Better check our demos how to use two-way binding with multiple selection.

Thanks for your prompt reply.
Actually I was following the example and made sure @bind-Value is a IENumerable string.
But it immediately prompted 3 errors as seen in the previous post. But when I change @bind-Value to a string variable, there is no error. But when running the program and after selecting an item, it prompts another problem--Error: System.InvalidCastException: Unable to cast object of type 'System.Linq.EnumerableQuery`1[System.String]' to type 'System.String

Oh, I found the problem. I added TValue. It should be removed
