          TData="City"
          TValue="City"
          AllowCustomTags ="true"
          @bind-Tags="@Tags">
            <TagTemplate Context="tagInfo">
                @{
                    var styleMode = tagInfo.IsCustom ? ButtonRenderStyleMode.Contained: GetModeByID(tagInfo.DataItem.CountryId);
                    var style = tagInfo.IsCustom ? ButtonRenderStyle.Dark : ButtonRenderStyle.Primary;
                    <DxButton RenderStyle="@style"
                              RenderStyleMode="@styleMode"
                              Text="@tagInfo.Text"
                              style="display:inline-block">
                        @context
                        <span @onclick="@tagInfo.RemoveTagAction">&times;</span>
                    </DxButton>
                }
            </TagTemplate>
</DxTagBox>

@code {
    List<City> DataSource { get; set; }
    IEnumerable<string> Tags { get; set; }

    ButtonRenderStyleMode GetModeByID(int countryId) {
        switch (countryId) {
            case 0: return ButtonRenderStyleMode.Contained;
            case 1: return ButtonRenderStyleMode.Outline;
            default: return ButtonRenderStyleMode.Text;
        }
    }

    protected override void OnInitialized() {
        base.OnInitialized();
        DataSource = CityData.Cities;
        Tags = new List<string>() { "Los Angeles", "Tokyo", "Moscow" };
    }
}
