I have a page that in the right side I have billing address (that is user control) and on the left side I have another user control that is shipping address. I have a checkbox in the page that by checking this checkbox I would like to fill out the shipping address with billing address. I usefully do this with JavaScript function but as long as here these 2 set of textboxes are user control I dont know how I can do this.

make chechbox=>Properties=>autopostback=true,
in check event

if(chechbox.checked)
{
textbox2.Text=textbox1.Text;
}
else
textbox2.Text="";

//or
if(chechbox.checked)
{
foreach (Control c in form1.Controls)
        {
            if (c.GetType().Name.ToLower() == "webusercontrol_ascx")
            {
                UserControl uc = (UserControl)c;
                TextBox txt = (TextBox)uc.FindControl("txtShiptoName");
                TextBox txt2 = (TextBox)uc.FindControl("txtShiptoName2");
                txt2.Text = txt.Text;
            }
