Adding data separate data grid view

问题

I want to add data in 2 data gridview but they are in separate form how will i do it? The datagridview1 is in form1 and the datagridview2 is in form2. Because in form1 they cant see the data gridview2 because it is on the other form.

You can do it like this ... In form 1 create a property

private static Form1 instance1;
public string propertyForm1;
public static Form1 Instance1
{
    get
    {
        if (instance1 == null)
            instance1 = new Form1();

        return instance1;
    }
}

And, in Form2

private static Form1 instance2;
public string propertyForm2;
public static Form2 Instance2
{
    get
    {
        if (instance2 == null)
            instance2 = new Form2();

        return instance2;
    }
}

Now you can access this property in either of any Form1 or Form2 or any Forms/Classes within your project like this...

Form1.Instance.propertyForm1 = "your assigned value from form2";
Form2.Instance.propertyForm2 = "your assigned value from form1";

Hope this helps you. And, dont forget to mark as answer if this worked for you.
