What is not actually validating. Whether it is displaying message or not validating at all even if you are not entering any value to the textbox. Please go through below link:

Solution 1

Two things, the first should fix your problem.

1) You need to add ValidationGroup to your web controls, such as: <asp:TextBox ID="txt_r_confirmpwd" runat="server" ValidationGroup="register" TextMode="Password" CssClass="txt_register">

2) It is best practice to use the Page.IsValid method when submitting a form, because it will force the validation controls to run on the server side too.

Page.Validate();
        if (!Page.IsValid)
        {
            Literal1.Text = "* Form is incomplete";
        }
        else
        {
            //insert data
        }

The button click event.

jgakenhe 8-Dec-15 1:23am

protected void btn_r_submit_Click(object sender, EventArgs e)
{
Page.Validate();
if (!Page.IsValid)
{
lbl_registermessage.Text = "* Form is incomplete";
}
else
{
con.Open();
string strid = "select count(*) from tbl_user_register";
SqlCommand cmdid = new SqlCommand(strid, con);
int count = Convert.ToInt16(cmdid.ExecuteScalar()) + 1;
string struserid = count.ToString();

string strquery = "insert into tbl_user_register values('"+struserid+"','" + txt_fname.Text + "','" + txt_dob.Text + "','" + txt_r_loginid.Text + "','" + txt_r_pwd.Text + "','" + txt_r_confirmpwd + "','" + txt_r_email.Text + "','" + txt_r_mobile.Text + "')";

SqlCommand cmdregister = new SqlCommand(strquery, con);
if (cmdregister.ExecuteNonQuery()>0)
{

Response.Write("<Script>alert('Successfully Registered in GVK Academy..')</Script>");

con.Close();
}
else
{
try
{
con.Open();
}
catch (Exception ex)
{
Response.Write(ex.Message);
//return false;
con.Close();
}
}
}
}

Solution 2

There are couple of possibility of your problem
1. You should check Page.IsValid before code execution on button click.
2. if you are using 'asp:Button' and .CS file for code behind then you should fire Serverclick event
