Transferring data from Form2 (textbox2) to Form1 (textbox1)? [duplicate]

Answer 1

Make a public variable and pass it the value from your text box and then onto your second form.

public static string myVar;   
myVar = txtForm2.Text;

and when you return to the first form: txtForm1.Text = Form2.myVar;

Answer 2

in Form1:

public void SetTextboxText(String text)
{
    txtForm1.Text = text;
}

private void btnForm1_Click(object sender, EventArgs e)
{
    var frm = new Form2(this); // pass parent form (this) in constructor
    frm.Show();
}

in Form2:

Form _parentForm;

public Form2(Form form)
{
    _parentForm = form;
}

private void txtForm2_TextChanged(object sender, EventArgs e)
{
    _parentForm.SetTextboxText(txtForm2.Text); // change Form1.txtForm1.Text
}

Answer 3

Try this ;)

On Form1:

private void button1_Click(object sender, EventArgs e)
    {
        Form2 frm2 = new Form2(textBox1.Text);
        frm2.Show();
        this.Hide();
    }

On form2:

public partial class Form2 : Form
{
    public string textBoxValue;
    public Form2()
    {
        InitializeComponent();
    }

    public Form2(string textBoxValue)
    {
        InitializeComponent();
        this.textBoxValue = textBoxValue;
    }

    private void Form2_Load(object sender, EventArgs e)
    {
        textBox2.Text = textBoxValue;
    }

Answer 4

In your Form2 you should have some like:

private void btnForm2_Click(object sender, EventArgs e)
 {          
   this.Hide();       
 }


public String GettxtForm2()
{
    return txtForm2.Text;
}

Now in form1 you can acces that txtForm2 with something like:

Form2 form2 = new Form2();
 //on click btnForm1 show that form2 where you can edit the txtForm2
 private void btnForm1_Click(object sender, EventArgs e)
     {                
       form2.Show();       
     }
   //after you save the txtForm2 when you will focus back to form1 the txtForm1 will get the value from txtForm2
   private void Form1_Enter(object sender, EventArgs e)
        {
             txtForm1.Text = Form2.GettxtForm2();
        }

You can easy modify the events where all this logic can occur...
