Hi,

I assume you are referring to using the control in a form ? If so you will need to expose the TextBox as a public property of the UserControl:

 public TextBox MyTextBox
        {
            get { return txtMyEntry; }
            set { txtMyEntry = value; }
        }

Then, in the form you can reference it as MyUserControlName.MyTextBox.Text etc. But you might consider only exposing those properties of the TextBox that you want to be accessible in this way - the above may be too flexible
