第三方控件如何加载以及调用？

<%@ Register TagPrefix="myCompany" TagName="CarCtl" Src="Car.ascx" %>
[C#]
    // Add other code here.

    // Binds the car object to the control declared
    // in the following code.
    myCarCtl.Car = car;
    myCarCtl.DataBind();

    // Add other code here.

    <%-- Control declaration --%>
    <myCompany:CarCtl id="myCarCtl" runat="server" />
如果愿意，也可以使用 LoadControl 方法取代 @ Register 指令，如以下代码所示。
[C#]
// Use the LoadControl method.
    CarCtl = LoadControl("Car.ascx")
    Form.Controls.Add(CarCtl);
    // Insert the remainder of the previous code here.
