[RESOLVED] [3.0/LINQ] Get Value from Other Form

Hi, I've tried a lot of manipulations to get the current data in a textbox from other form but it always return an empty. How to get the recent value? below is part of the code i hv started:

Code:

---

--code in Form2
Form1 frm1 = new Form1();
frm2txtbox.text=frm1.frm1txtbox.text;

---

i keep changing the text value of frm1txtbox at run time, but still frm2txtbox.text still empty. i've already set the modifier of the frm1txtbox into Public. need ur advise..

Hey,

By default, TextBox are set to private in C#, so in order to access the control on another form, you either have to change the protection level of the form, or create a public property that will set and get the text.

The code that you have above will always return null, since you are creating a new instance of Form2, which will always reset the Text Property of the form. However, I am going to assume that above it not all of the code.

Here is one way of doing it, but bear in mind there are other ways:

Main Form Code:

Code:

---

    public partial class MainForm : Form
    {
        public MainForm()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            SecondForm secondForm = new SecondForm();
            secondForm.Owner = this;
            secondForm.Show();
        }

        public string TextBoxText
        {
            get
            {
                return this.textBox1.Text;
            }
            set
            {
                this.textBox1.Text = value;
            }
        }
    }

---

Second Form Code:

Code:

---

    public partial class SecondForm : Form
    {
        public SecondForm()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            MainForm mainForm = (MainForm)this.Owner;
            mainForm.TextBoxText = this.textBox1.Text;
        }
    }

---

Here I have used the Owner Property to expose a reference to the first form from the second one.

That make sense?
