Good day everyone i am working on an application in c# windows form that has two usercontrol place on a form.

 

the first one is for registration i.e to register the second one is to view the registered users, to crud. and also has a datagriedview. whenever i register a new it does not show in the second usercontrol except i exit and re-run the code before it will get updated in the datagridview. please i want whenever i insert a new record it should show in the second usercontrol. not only datagridview even label thanks to get updated.

 

this is the usercontrol for registration

private void btnreg_Click(object sender, EventArgs e)
{
userprofile up = new userprofile();
if (txtempno.Text != null && txtfullname.Text != null && dob.Value != null && txtdept.Text != null && txtoccupation.Text != null && txtmaritalstatus.SelectedItem != null && txtemail.Text != null && txtpost.Text != null && txthaddress.Text != null && txtpno.Text != null && txtnation.Text != null && txtorigin.Text != null && pictureBox1.Image != null)
{
MemoryStream ms = new MemoryStream();
pictureBox1.Image.Save(ms, pictureBox1.Image.RawFormat);
byte[] img = ms.ToArray();

if (rfemale.Checked == true)
{
gender = "Female";
}
else if (rmale.Checked == true)
{
gender = "Male";
}
SqlDataAdapter da = new SqlDataAdapter("Select * FROM Registrationform where Employementnumber='" + txtempno.Text + "' or Email='" + txtemail.Text + "' ", con);
DataTable dt = new DataTable();
da.Fill(dt);
if (dt.Rows.Count >= 1)
{
MessageBox.Show("already exist");
}
else
{
con.Open();
SqlCommand cmd = new SqlCommand();
cmd.Connection = con;
cmd.CommandText = "INSERT INTO Registrationform([Employementnumber],[FullName],[Dateofbirth],[Gender],[Occupation],[Maritalstatus],[Email],[Department],[Position],[HomeAddress],[Phonenumber],[Nationality],[Stateoforigin],[image]) VALUES (@empno,@fullname,@dob,@gen,@occ,@ms,@email,@dept,@post,@haddress,@pno,@nation,@soo,@img)";
cmd.Parameters.AddWithValue("@empno", txtempno.Text);
cmd.Parameters.AddWithValue("@fullname", txtfullname.Text);
cmd.Parameters.AddWithValue("@dob", dob.Value);
cmd.Parameters.AddWithValue("@gen", gender);
cmd.Parameters.AddWithValue("@occ", txtoccupation.Text);

cmd.Parameters.AddWithValue("@pno", txtpno.Text);
cmd.Parameters.AddWithValue("@nation", txtnation.Text);
cmd.Parameters.AddWithValue("@soo", txtorigin.Text);
cmd.Parameters.AddWithValue("@img", img);
cmd.ExecuteNonQuery();
con.Close();
MessageBox.Show("data entered");
da.Fill(dt);
BindingSource bd = new BindingSource();
up.dtuserpro.DataSource = dt;
up.dtuserpro.DataSource = bd;
con.Close();
}
