Call this method to show the context menu in relation to the target element. Use the PositionTarget property to specify this element. If you do not specify the PositionTarget property value, this method displays the context menu at the top left corner of a web page.

The following example displays the context menu at the top of the <div> element:

<style>
    .context-menu-container {
        margin-top: 100px;
        height: 50px;
        width: 200px;
        border: 1px solid black;
    }
</style>

<DxButton Text="Show Context Menu" 
          Click="() => ContextMenu.ShowAsync(ContextMenuPosition.Top)" />

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

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

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

To execute custom code when the context menu is displayed, handle the Shown event. Call the HideAsync() method to hide the context menu.
