How to pass value from Form to UserControl?

Question

I need to pass a value from Form to UserControl.

I have tried to: 1.(and i make basketBox public) Form:

UserControlBasket us1 = new UserControlBasket();
public void button1_Click(object sender, EventArgs e)
{
    us1.basketBox.Text = g1.Name;
}

2. Form:

UserControlBasket us1 = new UserControlBasket();
public void button1_Click(object sender, EventArgs e)
{
    us1.Txt = g1.Name;
}

UserControl:

public string Txt
{
    get { return basketBox.Text; }
    set { basketBox.Text = value; }
}

3. And i have tried to do like here: Pass value from Usercontrol to Form

I expect that in basketBox(it is a textBox) will be value from a g1.Name;

Answer 1

I just add a Controls.Add(us1) and it solved my problem.

Answer 2

I am just summarizing the comments (from @Jimi) with my answer here. Both the number 2 and 3 Solutions are acceptable and correct by design principles. It seems that a different object of user control was accessed here instead of using the one that placed the from.

Answer 3

In your case, you should better use textbox, which is attached to page and dont use a UserControl.
