A tab page can include other DevExpress Blazor components. The following code creates a tab page with the DxGrid component.

<DxTabs style="width:950px">
    <DxTabPage Text="Description">
        <div class="p-3">
            <b>7-Day Weather Forecast</b>
        </div>
    </DxTabPage>
    <DxTabPage Text="Forecast">
        <div class="py-3">
