推荐答案

vashikhan，

首先，您必须在form2中创建一个重载的构造函数，并在form1中创建一个全局对象，您已经存在的默认构造函数为:

Hi vashikhan,

first you must create an overloaded constructor in form2 and a global object of form1 , your already existing default constructor is :

public Form2()
{
     InitializeComponent();
}

全局对象和重载的构造函数代码将是:

The global object and the overloaded constructor code will be :

public static Form1 Frm1 = new Form1();

public Form2(Form1 form)
{
     InitializeComponent();
     Frm1 = form;
}

现在，您可以在form1的修饰符中将datagridview设置为public.

然后在点击添加按钮事件中，您将插入以下代码以打开form2:

Now you can set your datagridview in form1 ''s modifier to public .

Then in the click add button event you will insert this code for opening form2 :

Form2 Frm2 =new Form2(this);
Frm2.show();

希望对您有帮助，
祝你好运

I Hope this help you ,
Good luck
