Text not showing in text box

orderNo is increased by 1 everytime the createOrder form is opened. The orderNo is not displaying in the textbox11. I have to enter something into the textbox for it to change automatically to the counter.

public int orderNo;

private void textBox11_TextChanged(object sender, EventArgs e)
{
    textBox11.Text = Convert.ToString(orderNo);
}

EDIT - put code into form_load, but the counter seems not to change once createOrder form is opened.

Josh is correct if you want to make the functionality you wish on Load_Form event add:

textBox11.Text = Convert.ToString(orderNo);

or add a second textbox and set:

textBox2.Text=orderNo.ToString();
textBox2.Visible=False;
private void textBox2_TextChanged(object sender, EventArgs e)
{
    textBox11.Text = Convert.ToString(orderNo);
}

The reason is that textBox_TextChanged is not going to be called by the text box until user (or other piece of code) changes it's contents. Wherever you set orderNo should update the text. Do something like the following

private int orderNo;
public int OrderNo
{
    get { return this.orderNo; }
    set { this.orderNo = value; textBox11.Text = Convert.ToString(orderNo); }
}

And then in your code, everywhere you set orderNo, change it to use OrderNo to set it through a property.
