Use a validation summary control somewhere on your page...

<asp:validationsummary id="valSummary" runat="server" headertext="Validation Errors:" cssclass="ValidationSummary" />`

Then to validate:

<asp:textbox id="txtPostalCode" runat="server" MaxLength="250" Width="160px" text='<%# Bind("PostalCode") %>'></asp:textbox>

<asp:requiredfieldvalidator id="reqPostalCode" runat="server" errormessage="Postal code is required." controltovalidate="txtPostalCode">*</asp:requiredfieldvalidator>

Remove the "*" if you don't want immediate feedback... the errormessage is displayed in the <asp:validationsummary> control when you submit the form.

Try this one for creating dynamic radio buttons along with required field validators... 

    TableRow trow4 = new TableRow();
    trow4.Style.Add("width", "100px");
    TableCell tcel4 = new TableCell();
    Label lb4 = new Label();
    lb4.Text = Resources.QcLabelName.Gender;
    tcel4.Controls.Add(lb4);
    CSSCell(tcel4);
    table.Rows.Add(trow4);
    RadioButtonList rblist = new RadioButtonList();
    rblist.ID = "rbtnmalendfemale";
    rblist.Items.Add("Male");
    rblist.Items.Add("Female");
    tcel4.Controls.Add(rblist);
    trow4.Cells.Add(tcel4);
    table.Rows.Add(trow4);
    rblist.Visible = true;
    RequiredFieldValidator rFV5 = new RequiredFieldValidator();
    TableCell tcl46 = new TableCell();
    rFV5.ControlToValidate = "rbtnmalendfemale";
    rFV5.ErrorMessage = "Gendor Selection Is Mandatory";
    rFV5.Style.Add("color", "Red");
    rFV5.ID = "Reqfield9";
    tcl46.Controls.Add(rFV5);
    trow4.Cells.Add(tcl46);
    table.Rows.Add(trow4);
    rFV5.Visible = true;

Set the forecolor property of the validator to the background color of your page. Then in the onclientclick of the submit button, change the css color property to the desired color:

<asp:CompareValidator ID="birthdaycheck" runat="server" ErrorMessage="" 
    Text="*Required" ControlToValidate="birthday" ValidationGroup="rfi" 
    Operator="NotEqual"  ForeColor="#F3F3E9"  />  


<asp:Button ID="btnFinish" runat="server" Text="Finish"
    CausesValidation="true" CommandName="MoveComplete" CssClass="navButton" 
    ValidationGroup="rfi" 
    OnClientClick="$('#wizard_birthdaycheck').css('color','red');" />

You could set CausesValidation="False" for the button for which you don't want validation to happen.

<asp:Button ID="btnCancel" runat="server" Text="cancel" CausesValidation="False"
                            onclick="btnCancel_Click"/>

This isn't possible when ClientScript is enabled for your validators. And the ClientScript is by default enabled for your validators. You need to disable this by settings EnableClientScript to False in your source.

Now in the event handler of your submit button call Page.Validate() and Page.IsValid to see if every validators did pass the test.

Example:

<asp:RequiredFieldValidator ID="rfvFirstName" runat="server" ControlToValidate="txtFirstName" EnableClientScript="false" Display="Dynamic" SetFocusOnError="true" />

Page.Validate();
if (!Page.IsValid)
{
     //show a message or throw an exception
}

Normally it appears only when you enter text, delete it again and then move out of the textbox. I think this is by design. Try to change EnableClientScript property.
