Export HTML Table to Excel - asp.net

Question

I have HTML table on the ASP.NET MVC View page. Now I have to export this table to Excel.
(1) I have used partial view (Inquiries.ascx) to display the table data from database (using LINQ to Entity)
(2) I also have used UITableFilter plugin to filter the records (Ex: http://gregweber.info/projects/demo/flavorzoom.html )
(3) At any point of time, I have to filter the visible records to Excel.
Appreciate your responses.
Thanks

Here is my View:
<%# Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Mvc.Master" Inherits="System.Web.Mvc.ViewPage" %>
<asp:Content ID="Content2" ContentPlaceHolderID="cphHead" runat="server">
<script src="../../Scripts/jquery.tablesorter.js" type="text/javascript"></script>
<script src="../../Scripts/jquery.uitablefilter.js" type="text/javascript"></script>
<script type="text/javascript">
//Load Partial View
$('#MyInquiries').load('/Home/Inquiries');
// To Apply Filter Expression using uiTableFilter plugin
$("#searchName").keyup(function() {
$.uiTableFilter($("#tblRefRequests"), this.value);
$("#tblRefRequests").tablesorter({ widthFixed: true, widgets: ['zebra'] });
});
//Export the HTML table contents to Excel
$('#export').click(function() {
//Code goes here
});
</script>
</asp:Content>
//Main Content
<asp:Content ID="Content1" ContentPlaceHolderID="cphContent" runat="server">
<h2 class="pageName">View All Inquiries</h2>
<input type="submit" value="Export to Excel" id="export" />
<div id='MyInquiries'></div>
</asp:Content>
Strongly Typed Partial view user control (Inquiries.ascx) to generate table:
<table>
<tr><td valign ="middle">Filter Expression: <%= Html.TextBox("searchName")%></td></tr>
</table>
<table id="tblRefRequests" >
<thead>
<tr>
<th>Tx_ID</th>
<th>TX Date</th>
<th>Name</th>
<th>Email Address </th>
<th>Products</th>
<th>Document Name</th>
</tr>
</thead>
<tbody>
<% foreach (var item in Model) { %>
<tr>
<td visible =false><%= item.RequestID %></td>
<td><%= String.Format("{0:d}", item.RequestDate) %></td>
<td><%= item.CustomerName %></td>
<td><%= Html.Encode(item.Email) %></td>
<td><%= item.ProductName %></td>
<td><%= Html.Encode(item.DocDescription)%></td>
</tr>
<% } %>
</tbody>
</table>
Here is my Controller code to load the Inquiries partial view:
[HttpGet]
public PartialViewResult Inquiries()
{
var model = from i in myEntity.Inquiries
where i.User_Id == 5
orderby i.TX_Id descending
select new {
RequestID = i.TX_Id,
CustomerName = i.CustomerMaster.FirstName,
RequestDate = i.RequestDate,
Email = i.CustomerMaster.MS_Id,
DocDescription = i.Document.Description,
ProductName = i.Product.Name
};
return PartialView(model);
}

Answer 1

Try the jQuery plugin: table2csv. Use the argument, delivery:'value', to return the csv as a string.
Here is an implementation:
Add a regular html input button and a .NET HiddenField to the page
Add an onclick event to that button called "Export"
Create a javascript function, Export, that stores the return value of table2CSV() into the hidden field, and posts back.
The server receives the hiddenfield post data (the csv as a string)
The server outputs the string to the browser as a csv file
.
// javascript
function Export()
{
$('#yourHiddenFieldId').val() = $('#yourTable').table2CSV({delivery:'value'});
__doPostBack('#yourExportBtnId', '');
}
// c#
if(Page.IsPostBack)
{
if(!String.IsNullOrEmpty(Request.Form[yourHiddenField.UniqueId]))
{
Response.Clear();
Response.ContentType = "text/csv";
Response.AddHeader("Content-Disposition", "attachment; filename=TheReport.csv");
Response.Flush();
Response.Write(Request.Form[yourHiddenField.UniqueID]);
Response.End();
}
}

download components:npm install table-to-excel
https://github.com/ecofe/tabletoexcel
var tableToExcel=new TableToExcel();
document.getElementById('button1').onclick=function(){
tableToExcel.render("table");
};
document.getElementById('button2').onclick=function(){
var arr=[
['LastName','Sales','Country','Quarter'],
['Smith','23','UK','Qtr 3'],
['Johnson','14808','USA','Qtr 4']
]
tableToExcel.render(arr,[{text:"create",bg:"#000",color:"#fff"},{text:"createcreate",bg:"#ddd",color:"#fff"}]);
};
