Usercontrol與不同的aspx，但相同的實現

Question

我想區分用戶控件的視覺方面，但使用相同的代碼隱藏。 即我想在.ascx文件中使用兩個usercontrol：

CodeBehind =“Uploader.ascx.cs”Inherits =“Comptech2.moduli.uploader.Uploader”

通過這種方式，我可以在不改變背后的代碼的情況下改變視覺方面。

謝謝Alberto

為usercontrol創建一個基類，最終的usercontrols（* .aspx文件）將從基類派生。

// 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;
    }
}
