Trigger A User Control Update From Another?

is there an easy way to update a user control from another user control? i have a input box and a submit button. the user inputs a code, hits sumbit and based on the code, points are applied to thier score (another user control). the points are applied to the score in the database but don't show up on the page display until i hit refresh. is there an easy way to update the control on submit?

protected void btn_Add_Coupon_Click(object sender, EventArgs e)
{
try
{
SqlDataSourceTEST.DataSourceMode = SqlDataSourceMode.DataReader;
IDataReader Reader = (IDataReader)SqlDataSourceTEST.Select(DataSourceSelectArguments.Empty);
if (Reader.Read())
{
int iPoints = 0;
iPoints = (int)Reader["Points"];
if (iPoints > 0)
{
Profile.TimesVisited = Profile.TimesVisited + iPoints;
lblcoup.Text = iPoints.ToString() + " have been added to your score!";
}
else
{
lblcoup.Text = "Coupon Code Not Valid";
}
}
Reader.Close();
Reader.Dispose();
}
catch (Exception ex)
{
}
}
