<div class="form-group">
<label for="warehouse" class="col-sm-2 control-label">Transaction type</label>
<div class="col-sm-7">
#Html.TextBoxFor(m => m.vwint0, ViewBag.action_flag == "Create" ? (object)new { #class = "form-control", style = "width : 120px", #maxlength = 10 } : new { #disabled = "disabled", style = "width : 120px" })
#Html.ValidationMessageFor(m => m.vwint0)
</div>
</div>
<div class="form-group">
<label for="code" class="col-sm-2 control-label">Customer code</label>
<div class="col-sm-7">
#Html.DropDownListFor(m => m.vwstring1, ViewBag.cus as SelectList, "Select", new { #class = "form-control" })
</div>
</div>
<div class="form-group">
<div class="col-sm-9 col-sm-offset-3">
<button type="submit" class="btn btn-primary" name="update" value="headsub">Submit</button>
</div>
</div>
</form>
<form class="form-horizontal" role="form" method="post" id="details">
<div class="form-group">

<div class="col-sm-9">
#Html.TextBoxFor(m => m.vwint0, new { #class = "form-control", style = "width : 80px", maxlength = 10 })
</div>
</div>
<div class="form-group">
<label for="email" class="col-sm-2 control-label">Quote sequence</label>
<div class="col-sm-9">
#Html.TextBoxFor(m => m.vwstring9, new { #class = "form-control", style = "width : 80px", maxlength = 10 })
</div>
</div>
<div class="form-group">
<label for="password" class="col-sm-2 control-label">Item code</label>
<div class="col-sm-9">
#Html.DropDownListFor(m => m.vwstring10, ViewBag.item as SelectList, "Select", new { #class = "form-control" })
</div>
</div>
<div class="form-group">
<div class="col-sm-9 col-sm-offset-3">
<button type="submit" class="btn btn-primary" name="update" value="detailsub">Submit</button>
</div>
</div>
</form>
</div>
In my controller, I tried this but my controller isn't even recognizing the button name.
if (update == "headsub")
{
AR_002_SALES gdoc = new AR_002_SALES();
gdoc.sale_sequence_number = glay.vwint0;
gdoc.customer_code = glay.vwstring1;
gdoc.currency_code = glay.vwstring2;
}
else
{
AR_002_QUOTE = new AR_002_QUOTE();
AR_002_QUOTE.sale_sequence_number = glay.vwint0;
AR_002_QUOTE.quote_sequence = glay.vwstring9;
AR_002_QUOTE.item_code = string.IsNullOrWhiteSpace(glay.vwstring10) ? "" : glay.vwstring10;
AR_002_QUOTE.quote_qty = glay.vwdclarray0[0];
AR_002_QUOTE.price = glay.vwdclarray0[1];
}

Instead of using <form class="form-horizontal" role="form" method="post" id="head">
use #using (Html.BeginForm("ActionMethod", "Controller", FormMethod.Post, new { #class = "form-horizontal" ,#id="head" }))
to submit a form and action method will process that form and does stuff.Similarly you can do for another form also.
In your .cshtml it looks like it will not hit any action method of that controller.
