When I create multiple tabs and each tab has the same type of component, the OnInitialized is only running for the first one I click on.  

Here is a simplified example to demonstrate:

MAIN PAGE:

@page "/tabtest"
@using Telerik.Blazor.Components

<div>Product XYZ</div>

<TelerikTabStrip TabPosition="Telerik.Blazor.TabPosition.Top" @ref="productTabStrip" @bind-ActiveTabIndex="@ActiveTabIndex">
    <TabStripTab Title="Details">
        <div class="container sms-tab-content">
            GENERAL PRODUCT INTRO STUFF HERE
        </div>
    </TabStripTab>

    @foreach (var item in listOfWidgets)
    {
        <TabStripTab Title="@item.WidgetName" Disabled="false">
            <Widget WidgetID="@item.WidgetID" WidgetName="@item.WidgetName" />
        </TabStripTab>
    }

</TelerikTabStrip>

<div style="margin-top: 15px;">
    <div><b>Below is a flat non-tab example of repeating widgets:</b></div>
    @foreach (var item in listOfWidgets)
    {        
        <Widget WidgetID="@item.WidgetID" WidgetName="@item.WidgetName" />        
    }
</div>


@code {

    Telerik.Blazor.Components.TelerikTabStrip productTabStrip;

    public int ActiveTabIndex { get; set; } = 0;

    protected class Widget
    {
        public int WidgetID { get; set; }
        public string WidgetName { get; set; }
    }

    private List<Widget> listOfWidgets = new List<Widget>();

    protected void GetData()
    {
        listOfWidgets.Add(new Widget { WidgetID = 1, WidgetName = "Cog" });
        listOfWidgets.Add(new Widget { WidgetID = 2, WidgetName = "Wheel" });
        listOfWidgets.Add(new Widget { WidgetID = 3, WidgetName = "Bloof" });
    }

    protected override void OnInitialized()
    {
        GetData();
    }

}    

 

WIDGET COMPONENT:

@page "/widget/{WidgetID:int}/{WidgetName}"

<div>
    <div>@WidgetID</div>
    <div>@WidgetName</div>
    <div>@ExtraWidgetInfo</div>
</div>

@code {


    [Parameter] public int WidgetID { get; set; } = 0;
    [Parameter] public string WidgetName { get; set; } = "Nothing";

    private string ExtraWidgetInfo { get; set; } = "Stuff";

    protected override void OnInitialized()
    {
        if (WidgetName == "Cog")
            ExtraWidgetInfo = "This is good info about cogs.";
        if (WidgetName == "Wheel")
            ExtraWidgetInfo = "This is good info about wheels.";
        if (WidgetName == "Bloof")
            ExtraWidgetInfo = "This is good info about bloofs.";
    }

}
