Add a datagridview collumn from another form

Anonymous User 1802 18-Aug-2014

I have two forms and a datagridview which is in the form1.Im trying to add a new column by clicking in a button from form2.Like that:

 Form2

    private void button1_Click(object sender, EventArgs e)
    {
        Form1 form1 = new Form1();
        form1.dataGridView1.Columns.Add("test" , "test");
    }

How can I do that?

Hi Jay, 

Form1 form1 = new Form1();

This will not work as your real form1 is already there, I pressume. Instead create a reference to it in form2 and load it in form2's constructor!

Here are the steps:

the local reference to form1 in form2's variables:  Form1 form1

When opening form2 pass a reference to form1 in the constructor:

form2 = new Form2(this);

Store it in the local refence in the constructor on form2:

public Form2(Form1 form1_)
{
    InitializeComponent();
    form1 = form1_;
}
