Required field Validation and Modal popup occurs at the same time

I have a page where there are some text box with required fields and I have a submit button in the same page for which I have the Modal Pop up. When I click the submit button without filling the text box, the pop up is displayed and the error message is also displayed near the text box. 

<asp:TextBox ID="txt_ExpiresBy"
             class="datePicker" 
             runat="server" />
<asp:RequiredFieldValidator ID="req_ExpiresBy" 
                            ValidationGroup="SM" 
                            runat="server" 
                            ControlToValidate="txt_ExpiresBy" 
                            Text="*ExpiresBy is a required field.">
</asp:RequiredFieldValidator>
<asp:Button ID="btn_Send" 
            runat="server" 
            ValidationGroup="SM" 
            Text="Send" 
            CausesValidation="true" 
            OnClick="Send_Click" />                         
<asp:ModalPopupExtender ID="ModalPopupExtender1" 
                        TargetControlID="btn_Send" 
                        PopupControlID="Pnl_ForgotPass" 
                        runat="server">
</asp:ModalPopupExtender>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:Panel ID="Pnl_ForgotPass" runat="server" 
           CssClass="cpHeader">
    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
        <ContentTemplate>
            <asp:Button ID="Btn_ViewDash" runat="server" 
                        Text="View DashBoard" />
            <asp:Button ID="Btn_SeeMessages" runat="server" 
                        Text="Messages Page" />
        </ContentTemplate>
    </asp:UpdatePanel>
</asp:Panel>

I want to display the PopUp only after all the required fields are filled, but it displays before it. How to change it.

The summit button you have in the modal pop up needs to have this property

CausesValidation="false"

this property avoids the required fields to be fired when the modal popup summit/ok button is clicked

You could do this with some javascript.

First remove the TargetControlID="btn_Send" from ModalPopupExtender1 

<asp:ModalPopupExtender ID="ModalPopupExtender1" 
                    PopupControlID="Pnl_ForgotPass" 
                    runat="server">

Then, Add those scripts at the end of the page.

<script type="text/javascript">
  function ShowPopup() {
   $find('ModalPopupExtender1').Show();
  }

  function ValidateAndShowPopup() {
    if (Page_ClientValidate('SM')) {
        ShowPopup();
    }
  }
</script>

Then, bind the the OnClientClick event to the new script. 

<asp:Button ID="btn_Send" 
        runat="server" 
        ValidationGroup="SM" 
        Text="Send" 
        CausesValidation="true" 
        OnClientClick="ValidateAndShowPopup()"  />

By the way, the OnClick="Send_Click" event was shallowed by the behavior of the ModalPopupExtender's TargetControlID, So I removed it.

I suggest you to use a hiddenfield for that purpose you can see a solution on

ModalPopupExtender and Validation Controls.
