I'm trying to post an XML file using an html form for the inflight payment process but I get a "system unavailable" error. Is there any sample code for performing an XML post?
@using (Html.BeginForm(null, null, FormMethod.Post, new { @action = Model.PostUrl }))
{
@Html.HiddenFor(m => m.XmlData)
<row>
<div style="text-align: center">
<button type="submit" class="btn btn-success" style="width: 80px;">Post</button>
</div>
</row>
}
