Impossible to use RadioList when TValue is not string

[jasniec]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

I'd like to use RadioList with SelectedItem, however RadioList.Items does not allow to use generic version of SelectedItem.
SelectedItem does not inherrit SelectedItem which (I assume) would be the simplest solution.

Expected Behavior

I'm able to use it like below:

<RadioList TValue="MyDto" Items="MyGenericItems" bind-Value="Result"/>

@code {
    private SelectedItem<MyDto>[] Items { get; set; } = [ ... ];
    private MyDto? Result { get; set; }
}

Interactive render mode

Interactive WebAssembly (Client-side rendering (CSR) using Blazor WebAssembly)

@jasniec I don't understand your intention, this issue is classified as a bug but the description seems to be the intention. Please provide more information

[jasniec]

Since I see class SelectedItem and I'm able to add a generic parameter to RadioList, I consider it a bug, because I can't combine both together.

It seems someone forgot to handle generic SelectedItem in RadioList when doing generic version

@jasniec could you please submit a PR to fix this issue?

the title is not true, I have tried int?, it works, please be more specific.

[ArgoZhang]

@ice6 I didn't quite understand what he was trying to say so I couldn't react properly. I guess that it may be related to the generic model.

@jasniec could you try the RadioListGeneric<TValue> component? this is a new component maybe meet your requirement.

[ice6]

@ArgoZhang any docs for the RadioListGeneric component, I found nothing from the doc web site's search box.

[ArgoZhang]

@ice6 Yes. There is no relevant documentation yet, but it will be improved later. Currently, you can only learn about it through the source code.
