Another upgrade issue, I've looked in the documentation and cannot find any help.

I've upgraded from EJ2.Blazor v17.3.0.29-beta to v17.4.0.44 and it seems the "ItemSelected" event no longer works...

Example Razor

<EjsDropDownButton ItemSelected="ShowArchiveModal" Content="Archive As" Items="@CategoryButtonItems" />

Example void

void ShowArchiveModal(Syncfusion.EJ2.Blazor.SplitButtons.MenuEventArgs args)
collapsemaincontainer = true;

var modalparameters = new ModalParameters();
modalparameters.Add("InboxFileID", intInboxFileID);
modalparameters.Add("CategoryID", Int32.Parse(args.Item.Id));

var modaloptions = new ModalOptions()
DisableBackgroundCancel = true,
HideCloseButton = true

BlazoredModalService.OnClose += ArchiveModalClosed;
BlazoredModalService.Show<ArchiveInboxFileModal>("Archive File - " + args.Item.Text, modalparameters, modaloptions);

I get a browser breaking issue at runtime

System.InvalidOperationException: Object of type 'Syncfusion.EJ2.Blazor.SplitButtons.EjsDropDownButton' does not have a property matching the name 'ItemSelected'.

This worked in the beta and i'd followed Syncfusion code examples to get this working, what am i doing wrong?

Many thanks,

Hi Dean 
Thank you for contacting Syncfusion support 
We have checked your reported issue we would like to let you know that Event initialization has been changed in 17.4.39 version. Now, you need to specify events using the DropDownButtonEvents component. Please find the below code snippet: 
@using Syncfusion.EJ2.Blazor.SplitButtons 
<EjsDropDownButton  Items="@ddlItems" IconCss="e-ddb-icons e-profile"> 
    <DropDownButtonEvents ItemSelected="ShowArchiveModal"></DropDownButtonEvents> 
        public List<Syncfusion.EJ2.Blazor.SplitButtons.DropDownButtonItem> ddlItems { get; set; } = new List<Syncfusion.EJ2.Blazor.SplitButtons.DropDownButtonItem> 
            new Syncfusion.EJ2.Blazor.SplitButtons.DropDownButtonItem { Text = "Dashboard", IconCss = "e-ddb-icons e-dashboard" }, 
            new Syncfusion.EJ2.Blazor.SplitButtons.DropDownButtonItem { Text = "Notifications", IconCss = "e-ddb-icons e-notifications" }, 
            new Syncfusion.EJ2.Blazor.SplitButtons.DropDownButtonItem { Text = "User Settings", IconCss = "e-ddb-icons e-settings" }, 
            new Syncfusion.EJ2.Blazor.SplitButtons.DropDownButtonItem { Text = "Log Out", IconCss = "e-ddb-icons e-logout" } 
        public void ShowArchiveModal(MenuEventArgs args) 
            Console.WriteLine("select event triggered"); 
Please find the release notes link: 
Could you please check the above code snippet and get back to us if you need further assistance on this?
