You must use the required attribute with your server control not with a validation control
<form id="form1" runat="server">
Your name:<br />
<asp:TextBox runat="server" id="txtName" required="required"/>
<asp:RequiredFieldValidator runat="server" id="RequiredFieldValidator1" controltovalidate="Your_Name" ForeColor="Red" errormessage="Please enter your name!" />
<br /><br />
<asp:Button runat="server" id="btnSubmitForm" text="Ok" onclick="btnSubmitForm_Click" />
</form>
In the event handler of the CodeBehind file:
protected void btnSubmitForm_Click(object sender, EventArgs e)
{
if(Page.IsValid)
{
btnSubmitForm.Text = "My form is valid!";
}
}
