CreateContextMenuItem

Create a custom ContextMenuItem object to insert into the WebView context menu.

public HRESULT CreateContextMenuItem(LPCWSTR Label, IStream * iconStream, COREWEBVIEW2_CONTEXT_MENU_ITEM_KIND Kind, ICoreWebView2ContextMenuItem ** value)

CoreWebView2 will rewind the icon stream before decoding. There is a limit of 1000 active custom context menu items at a given time. Attempting to create more before deleting existing ones will fail with ERROR_NOT_ENOUGH_QUOTA. It is recommended to reuse ContextMenuItems across ContextMenuRequested events for performance. The returned ContextMenuItem object's IsEnabled property will default to TRUE and IsChecked property will default to FALSE. A CommandId will be assigned to the ContextMenuItem object that's unique across active custom context menu items, but command ID values of deleted ContextMenuItems can be reassigned.
