<div class="context-menu"
     @oncontextmenu:preventDefault>
    <span class="fw-600">RIGHT-CLICK TO SHOW THE CONTEXT MENU</span>
</div>

<DxContextMenu @ref="ContextMenu"
               PositionTarget=".context-menu">
    <Items>
        <DxContextMenuItem Text="Open" />
        <DxContextMenuItem Text="Copy" />
        <DxContextMenuItem Text="Delete" />
    </Items>
</DxContextMenu>

@code {
    DxContextMenu ContextMenu { get; set; }
}

.context-menu {
  margin-top: 15px;
  height: 50px;
  width: 200px;
  border: 1px solid black;
}
