用戶控件使用不同的aspx，但實現相同

Question

我想區分usercontrol的視覺方面，但使用相同的代碼隱藏。 即我想要兩個用戶控件用.ascx文件：

代碼隱藏=「Uploader.ascx.cs」繼承=「Comptech2.moduli.uploader.Uploader」

這樣我可以改變視覺方面不改變背後的代碼。

感謝 阿爾貝託

您的用戶控件創建一個基類，最終用戶控件（* .aspx文件）從基類派生。

// base class with common functionality 
public class MyUserControlBase : UserControl { 
    // derived class will initialize this property 
    public TextBox TextBox1 {get;set;} 
    // derived class will initialize this property 
    public Button Button1 {get;set;} 

    /* some code of usercontrol */ 
} 

/* ... elsewhere ... */ 
// final class with *.aspx file 
public class MyUserControlA : MyUserControlBase { 
    protected override OnInit(EventArgs e) { 
     // "this.txtUrl" is generated from *.aspx file 
     this.TextBox1 = this.txtUrl; 
     // "this.btnSubmit" is generated from *.aspx file 
     this.Button1 = this.btnSubmit; 
    } 
} 

/* ... elsewhere ... */ 
// final class with *.aspx file 
public class MyUserControlB : MyUserControlBase { 
    protected override OnInit(EventArgs e) { 
     // "this.txtTitle" is generated from *.aspx file 
     this.TextBox1 = this.txtTitle; 
     // "this.btnOk" is generated from *.aspx file 
     this.Button1 = this.btnOk; 
    } 
}
