Hi friend,

Little enhancement to the above code give by Micke.

foreach(Control ctl in Form.Controls)
{
   if(ctl is TextBox)
   {
      sb.Append(((TextBox)ctl).Text);
   }
}

txtBox_all_together.Text = sb.ToString();

Hope it helps you.

Use System.Text.StringBuilder class concatenate them:

System.Text.StringBuilder sb = new System.Text.StringBuilder();

sb.Append(txtBox1.Text);
sb.Append(txtBox2.Text);
sb.Append(txtBox3.Text);
sb.Append(txtBox4.Text);
sb.Append(txtBox5.Text);
sb.Append(txtBox6.Text);
sb.Append(txtBox7.Text);
sb.Append(txtBox8.Text);
sb.Append(txtBox9.Text);
sb.Append(txtBox10.Text);

txtBox_all_together.Text = sb.ToString();
