Hi All,
I have one .aspx page and integrating to payment gateway in asp.net.

I have four hidden field and one button control. form tag has action attribute has been set as URL of sagepay and method="post". When I click on button control, server code is not executing and it redirects to sage pay. I need to execute button click event so before redirecting user to sagepay website, I need to store order information in database table.

I already tried with Response.Redirect this one not working.
can anybody know how to fix this issue? Or any other way to integrate sagepay in asp.net.

.aspx page:
<form id="form2" action="https://test/gateway/test.jsp"
method="post">
<input type="hidden" name="VPSProtocol" value="2.23" />
<input type="hidden" name="TxType" value="PAYMENT" />
<input type="hidden" name="Vendor" value="vendorname" />
<input type="hidden" name="Crypt" value="orderInfo" />
<asp:Button ID="btnTest" runat="server" Text="Test SagePay" runat="server" OnClick="onclick_click" />
</form>

Thanks
Nagaraj

ASP.NET

<form id="form1" runat="server" method="post">    
    <asp:button id="btnTest" runat="server" text="Test SagePay" onclick="btnTest_click" xmlns:asp="#unknown" />
</form>

and

C#

protected void btnTest_click(object sender, EventArgs e)
        {
            //Code to save values into DB;
            Response.Redirect("https://test/gateway/test.jsp");
        }

Hope it helps.

As I already mentioned in question Response.Redirect will not post data to gateway. Please read question once again.

Well you didn't mention that you want to post data to Sagepay.

I don't have direct experience with Sagepay, so not sure if they accept query strings etc. But a form's action attribute will post the form before it can go to server side code.

The gateway will not accept query string. Thanks for your support.
