Extraction list to filter different records from db in asp.net mvc

Question

Hi Team

 

I have a button, but i want to know how can i extract the list of records from the button itself when clicked

public IList < ScheduleManModel > GetScheduleManList()
{
DbAccessContext db = new DbAccessContext();
var scheduleList = (from e in db.ScheduleMan join d in db.ScheduleTbl on e.ScheduleId equals d.YearTblId select new ScheduleManModel {
Year = e.Year,
Week = e.Week,
250 Buck = (int) e.250 Buck,
RACS = e.RACS,
YBR250 = d.YBR250
}).ToList();
return scheduleList;
}
public ActionResult ExtractionToExcel() {
var gv = new GridView();
gv.DataSource = this.ScheduleManList();
gv.DataBind();
Response.ClearContent();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment; filename=DemoExcel.xls");
Response.ContentType = "application/ms-excel";
Response.Charset = "";
StringWriter objStringWriter = new StringWriter();
HtmlTextWriter objHtmlTextWriter = new HtmlTextWriter(objStringWriter);
gv.RenderControl(objHtmlTextWriter);
Response.Output.Write(objStringWriter.ToString());
Response.Flush();
Response.End();
return View("Index");
}
}
}

@using (Html.BeginForm("ExportToExcel", "Schedule", FormMethod.Post))
{
<br />
<br />
<h2>

<table style="background-color: white; width: 100%;">

<th style="border: 2px solid black; text-align: center; width: 20%">

</tr>
@foreach (var itm in Model)
{
<tr>
<td colspan="4">
<br />
<br />
<input type="submit" value="Extraction" class="button" />
</td>
</tr>
</table>

Using asp.net mvc to export them as excel, has anyone ever worked on that before?
