Hi,

I'm trying to use the latest version (V1.1.0) of DropDownList with a GUID key, the original conversation is in this thread: https://www.telerik.com/forums/dropdownlist---run-code-when-select-item-changes.

My understanding is this should now work, but I'm having problems binding the current value. My code looks like this:

      <TelerikDropDownList Data="@_viewItems" TValue="Guid"
                             TextField="Name"
                             ValueField="Id"
                             bind-Value="@CurrentViewId" PopupHeight="120" />

 

    private List<NameAndId> _viewItems;

    public class NameAndId
    {
        public string Name { get; }
        public Guid Id { get; }

        public NameAndId(string name, Guid id)
        {
            Name = name;
            Id = id;
        }

        public override string ToString()
        {
            return Name;
        }
    }

    private Guid CurrentViewId
    {
        get => _currentViewId;
        set => _currentViewId = value;
    }

This gives me the following compiler error:

Severity    Code    Description    Project    File    Line    Suppression State
Error        The attribute names could not be inferred from bind attribute 'bind-Value'. Bind attributes should be of the form'bind', 'bind-value' or 'bind-value-change'    TestApp    C:\Source\TestApp.Blazor\TestApp.Blazor\Pages\View.razor    17    
Error    RZ9991    The attribute names could not be inferred from bind attribute 'bind-Value'. Bind attributes should be of the form'bind', 'bind-value' or 'bind-value-change'    TestApp  C:\Source\TestApp.Blazor\TestApp.Blazor\Pages\View.razor    17    

Thanks,

Nick.

Ignore that - I figured it out. It was missing the using statement:

@using Telerik.Blazor.Components.DropDownList

Unfortunately resharper shows it as redundant so I must have deleted it accidentally.
