并在 NavMenu.razor 文件中使用它。然后我收到以下错误。 'SfSidebar.Toggle()' is obsolete: 'This method is deprecated and will no longer be used. Use the IsOpen property to achieve this case.'然后我改变了

public void Toggle()
{
    this.Sidebar.Toggle();
}

如下，

public void Toggle()
{
    this.Sidebar.IsOpen();
}

然后我收到以下错误消息:- Non-invocable member 'SfSidebar.IsOpen' cannot be used like a method.如果你能帮我解决这个问题，我非常感激。
谢谢你。

Answer 1

我们已经检查了您报告的侧边栏组件问题。 IsOpen 是 属性(property)侧边栏组件。您已经定义了 isOpen 属性，就像调用方法一样。这可能是您报告的问题的原因。
有关 IsOpen 属性的定义，请参阅以下代码片段。

 <SfSidebar Width="220px" DockSize="72px" EnableDock="true" @bind-IsOpen="isOpen" Position="@Position" @ref="Sidebar" HtmlAttributes="@HtmlAttribute"> 
           <ChildContent> 
               <div class="dock"> 
               </div> 
           </ChildContent> 
       </SfSidebar> 
@code { 
public bool isOpen { get; set; } 
public void Toggle() 
   { 
       if (isOpen) 
       { 
           isOpen = false; 
      } 
       else 
       { 
           isOpen = true; 
       } 
   } 
}
