如何从特定班级获得特定控制权 [英] How to reach specific control from specific Class

问题描述

我在名为Globle的Web应用程序项目中上课，
并假设我有一个名为Homepage的页面.

我想知道如何从Globle Class达到首页中的特定控件，如下所示:

Hi,

I make class in my web application project called Globle,
and suppose i have page called Homepage.

I want to know how to reach specific control in Homepage from Globle Class as like this:

public class Globle
    {
        public static bool myMethod(Page Homepage)
        {
            Homepage.Controls.TextBox.Text = "any thing";

            return true;
        }
    }

谢谢.

thanks.

推荐答案

是的，可以.

试试，

Yeah you can.

Try,

(HomePage.FindControl("YOU_CONTROL_ID") as TextBox).Text = "Any thing";

您可能会在运行时获取NullException，因为

You might get NullException on runtime as because

HomePage.FindControl("YOU_CONTROL_ID")

或

or

HomePage.FindControl("YOU_CONTROL_ID") as TextBox

可以为null.添加适当的null异常处理就可以了.

我不确定它是什么类型的ASP.NET项目.您可以将Page中的控件的访问修饰符更改为public，然后像在问题中所说的那样访问它是否是Web应用程序.

can be null. Add appropriate null exception handling get going with it.

I am not sure what type of ASP.NET project is it. You can change the access modifier of the control in Page to public and access like you said in your question if it is Web Application.
