Unable to Display List in RadzenDataGrid Column as Comma separated string

I have the following model

 public class AssetProxyWrapper
    {
        public string AssetId { get; set; }
        public IEnumerable<string> dataCodes { get; set; }
    }

I'm trying to display this as a single string with comma as separator using the following approach

<RadzenDataGrid TItem=AssetProxyWrapper

                Data=assetProxyMappings

                AllowPaging="true"

                PageSize="20"

                AllowSorting="true"

                AllowFiltering="true"

                AllowColumnResize="true"

                Count=assetProxyCount

                FilterMode="FilterMode.Simple"

                IsLoading=isLoading              

                FilterCaseSensitivity="FilterCaseSensitivity.CaseInsensitive">

    <Columns>              

         <RadzenDataGridColumn TItem="AssetProxyWrapper" Property="AssetId" Title="Asset Id" />  

        <RadzenDataGridColumn TItem="AssetProxyWrapper" Property="@string.Join(",", dataCodes)" Title="Code" />        

    </Columns>
