I have a dotnet 3.1 Razor page with three buttons with asp-page-handler parameters inside the same form. The first and last one work (i.e., they go to the webpage with a handler query parameter equal to the string in the asp-page-handler parameter). The third one does not get the handler query parameter added.
Here's a code snippet (cshtml page):
@page
@model RMP.Pages.Client.SurveySetNameModel
@{
ViewData["Title"] = "SurveySetName";
Layout = "~/Pages/Shared/_Layout.cshtml";
}
<div class="breadcrumb">
<a class="breadcrumb-item" href="/Client/SurveyList/@Model.intUserId.ToString()">Surveys</a>
<span class="breadcrumb-item" id="breadcrumbText">Create New Survey</span>
</div>
<h1>Name your survey</h1>
<p>The name is for your purposes only, it will not be visible to people taking the survey.</p>
<form method="post">
<div>
<input asp-for="sinSurveyName" requried="required" placeholder="Survey Name" class="form-control frmInpt" />
<span asp-validation-for="sinSurveyName"></span>
</div>
<br />
<h2>Select a Type</h2>
<div class="card-deck">
<div class="card">
<div class="card-body">
<h5 class="card-title">Standard</h5>
<p>
Use our survey to find out some information.
</p>
<p>
Cost: 1 Standard credit
</p>
</div>
<div class="card-footer text-center">
@if (Model.dctTypeAvailability[1])
{
<input type="submit" class="btn btn-primary" value="Standard" asp-page-handler="Stan" />
}
else
{
<p>
<b>Not enough credits for this survey. Contact your sales rep.</b>
</p>
}
</div>
</div>
<div class="card">
<div class="card-body">
<h5 class="card-title">Standard + Custom</h5>
<p>
In addition to the standard do this
</p>
<p>Cost: 1 Standard credit and 1 Custom credit</p>
</div>
<div class="card-footer text-center" ">
@if (Model.dctTypeAvailability[3])
{
<input type="submit" class="btn btn-primary" value="Standard + Custom" asp-page-handler="StanCust" />
}
else
{
<p>

</p>
}
</div>
</div>
<div class="card">
<div class="card-body">
<h5 class="card-title">Custom</h5>
<p>
Write up to 10 questions
</p>
<p>Cost: 1 custom credit</p>
</div>
<div class="card-footer text-center" ">
@if (Model.dctTypeAvailability[2])
{

So, when clicking on the button that says "Standard", I get a post to the page with ?handler="Stan" appended and when clicking on the button that says "Custom", I get a post to the page with ?handler-"Cust" appended. However, when I click on the button that says "Standard + Custom", i get a post to the page with no query parameter appended.
What gives?
What am I doing wrong?
Thanks, Owen
