Answer 7

No, I have 2 forms

The UserControl have the datagrid with a DataSet and another things.

I use the XForm to insert a new row in the UserControl.
The data comes from the text boxes in the XForm

Answer 8

So you have 3 forms, user control, formX and Xform.
user control and Xform are already open ?
You want  Xform textbox.text to be entered into database by clicking button on formX

Answer 9

I need the XForm because otherwise I will have many controls on the Control.

There is only 1 TextBox are like 15 ...

Button 1 on formX is private - so you can't access it from form 1
Can you explain why you need to click FormX.button1 from form1

Oh sorry but doesn't work because the button have's another instructions... I forget it

I edit the code:

    public partial class Expedientes : UserControl
    {
        FormX AddNewForm = new FormX();

 private void button1_Click(object sender, EventArgs e)
{
AddNewForm.button1.Click+= new EventHandler(XEvent);
AddNewForm.Show();
}

  private void button2_Click(object sender, EventArgs e)
{
AddNewForm.Close();
}

private void XEvent(object sender, EventArgs e)
{
this.textBox1.Text="Some Word";
}
}

  public partial class Expedientes : UserControl

//FormX AddNewForm = new FormX();//1*  move to button event

 private void button1_Click(object sender, EventArgs e)
{
FormX AddNewForm = new FormX();
AddNewForm.Show();
}

private void button2_Click(object sender, EventArgs e)
{
AddNewForm.Close();//2*  or use AddNewForm.Hide()
}
}
