c# - 复制面板及其所有控件

转载作者：太空宇宙更新时间：2023-11-03 13:27:51

我正在做一个项目，我想生成一个包含三份副本的收据 - 学生副本，帐户副本，办公室副本。所有这些副本将具有相同的数据，除了标题。所以我所做的是生成一个面板并填充它并为三个副本制作了三个不同的 div。现在在填充面板后的后端，我在运行时制作了三个具有不同名称的面板并将该面板传递给它们，然后将这三个面板添加到它们各自的 div。通过这样做我只收到一次收据，而且是在最后一个 div 中。请帮助我如何实现这一点。

代码

public void generatereceipt()
{ //pnlreceipt is the main panel built in aspx page
    divstudent.Controls.Add(pnlreceipt);
    divpnlreceipt.Visible = true;
    divstudent.Visible = true;
    divoffice.Visible = true;
    divaccounts.Visible = true;
    Panel pnlstudent = new Panel();
    pnlstudent = pnlreceipt;
    divstudent.Controls.Add(pnlstudent);
    Panel pnloffice = new Panel();
    pnloffice = pnlreceipt;
    divoffice.Controls.Add(pnloffice);
    Panel pnlaccounts = new Panel();
    pnlaccounts = pnlreceipt;
    divaccounts.Controls.Add(pnlaccounts);
    divoffice.Visible = true;
    divaccounts.Visible = true;
}
