Easiest way to create a custom dialog box which returns a value?

I want to create a custom dialog box for my C# project. I want to have a DataGridView in this custom dialog box, and there will also be a button. When the user clicks this button, an integer value is returned to the caller, and the dialog box then terminates itself.

How can I achieve this?

    public partial class DialogFormDisplay : Form
{
    public DialogFormDisplay()
    {
        InitializeComponent();
    }
    string dialogcode;
    public void Display(string code, string title, string description)
    {
        dialogcode = code;
        switch (code)
        {
            case "YesNo":
                btnLeft.Text = "Yes";
                btnLeft.BackColor = Color.ForestGreen;
                btnLeft.ForeColor = Color.White;
                btnRight.Text = "No";
                btnRight.BackColor = Color.Red;
                btnRight.ForeColor = Color.White;
                break;
            default:
                break;
        }
        displayTitle.Text = title;
        displayMessage.Text = description;
    }

    private void btnLeft_Click(object sender, EventArgs e)
    {
        dialogResultLeft(dialogcode);
    }

    private void btnRight_Click(object sender, EventArgs e)
    {
        dialogResultRight(dialogcode);
    }
    void dialogResultLeft(string code)
    {
        switch (code)
        {
            case "YesNo":
                DialogResult = DialogResult.Yes;
                MessageBox.Show("You pressed " + DialogResult);
                break;
            default:
                break;
        }
    }
    void dialogResultRight(string code)
    {
        switch (code)
        {
            case "YesNo":
                DialogResult = DialogResult.No;
                MessageBox.Show("You pressed " + DialogResult);
                break;
            default:
                break;
        }
    }
}

  1. On your button set the DialogResult property to DialogResult.OK
  2. On your dialog set the AcceptButton property to your button
  3. Create a public property in your form called Result of int type
  4. Set the value of this property in the click event of your button

  5. Call your dialog in this way 

    using(myDialog dlg = new myDialog())
{
    if(dlg.ShowDialog() == DialogResult.OK)
    {
        int result = dlg.Result;
        // whatever you need to do with result
    }
}

There is no prompt dialog box in C#. You can create a custom prompt box to do this instead. 

  public static class Prompt
    {
        public static int ShowDialog(string text, string caption)
        {
            Form prompt = new Form();
            prompt.Width = 500;
            prompt.Height = 100;
            prompt.Text = caption;
            Label textLabel = new Label() { Left = 50, Top=20, Text=text };
            NumericUpDown inputBox = new NumericUpDown () { Left = 50, Top=50, Width=400 };
            Button confirmation = new Button() { Text = "Ok", Left=350, Width=100, Top=70 };
            confirmation.Click += (sender, e) => { prompt.Close(); };
            prompt.Controls.Add(confirmation);
            prompt.Controls.Add(textLabel);
            prompt.Controls.Add(inputBox);
            prompt.ShowDialog();
            return (int)inputBox.Value;
        }
    }

Then call it using:

 int promptValue = Prompt.ShowDialog("Test", "123");
