交互设计时用户控制 [英] Interactive Design-Time User Control

问题描述

如果标题很混乱，我们深表歉意，我花了将近5分钟才终于想到这个标题的标题...

好的，你知道如何当您向表单添加 TabControl 时，Visual Studio Express，您可以单击 TabControl ，它会添加一个新的 TabPage 或删除一个？

一个用户控制，我需要人们能够在面板之间切换（我的用户控制是由几个面板组成）。我知道这是可能的，因为我在过去使用过一个功能区 Control ，您可以在Designer视图中添加新的按钮等。

有人可以提供任何建议/建议，了解我如何去实现这个目标？

谢谢

Control 的控件时，你必须使用几个属性，例如： IsDesignMode ，那么您可以构造事件处理程序，特别是在设计模式中：

 
 if（IsDesignMode）{
 //在设计模式下处理交互性，例如更改
 // Properties工具箱上的属性
} 
 

假设控件有一个事件，例如 MouseClick ，你可以这样做：

 
 private void control_MouseClick（object sender，MouseEventArgs e）{
 if（IsDesignMode）{
 //根据Designer中的Click事件b} else {
 //这是在运行时... 
} 
} 
 

另一个我可以想到的是 ShouldSerialize '之后是一个可公开访问的属性，以便将属性持久化到设计器生成的代码，假设例如一个Control有一个布尔属性 Foo

 
 public bool Foo {
 get {return this._foo; } 
 set {if（this._foo！= value）{
 this._foo = value; 
} 
} 
} 
 
 public bool ShouldSerializeFoo（）{
 return true; //该属性将保留在设计器生成的代码中
 //检入Form.Designer.cs ... 
} 
 

如果 ShouldSerializeFoo 返回false，则不会保留任何属性，如果为true，则会隐藏在Form.Designer.cs代码中...

希望有帮助，
最好的问候，
汤姆。

I apologise if the title was confusing, it took me nearly 5 minutes to finally think of a title for this one...

Okay, you know how in Visual Studio Express when you add a TabControl to the Form, and you can click on the right-arrow on the top right of the TabControl and it will add a new TabPage, or remove one?

Well, I'm creating a User Control where I need people to be able to switch between Panels (my user control is made up of several Panels). I know this is possible as I've used a Ribbon Control in the past and you could add new buttons etc in the Designer View.

Can somebody please provide any suggestions/advice on how I might go about acheiving this?

Thank you

解决方案

When you make a control that is inherited from Control, you have to make use of a couple of properties such as IsDesignMode, you can then construct event handlers especially for within Design Mode:

if (IsDesignMode){
   // Handle the interactivity in Design mode, such as changing a property on the
   // Properties toolbox
}

Suppose the control has an event such as MouseClick, you can do this:

private void control_MouseClick(object sender, MouseEventArgs e){
   if (IsDesignMode){
       // Do something here depending on the Click event within the Designer
   }else{
       // This is at run-time...
   }
}

Another I can think of is 'ShouldSerialize' followed by a publicly accessible property in order to persist the property to the designer-generated code, suppose for example a Control has a boolean property Foo

public bool Foo{
    get{ return this._foo; }
    set{ if (this._foo != value){ 
                this._foo = value; 
         }
       }
}

public bool ShouldSerializeFoo(){
    return true; // The property will be persisted in the designer-generated code
                 // Check in Form.Designer.cs...
}

If ShouldSerializeFoo returned false, no property is persisted, its the opposite when true, it will be buried within the Form.Designer.cs code...

Hope this helps, Best regards, Tom.
