How can I make a loop to repeat my method for each item? - asp.net-mvc-3

Question

there is my issue. In a controller, I have this method which export my view in a file when I click a button.
public ActionResult Export(string searchString, int searchOrder = 0)
{
var user = from m in db.Orders select m;
if (!String.IsNullOrEmpty(searchString))
{
user = user.Where(s => s.ClientID.Contains(searchString));
}
Response.AddHeader("Content-Type", "application/vnd.ms-excel");
return this.View(user);
}
My Index view :
#model IEnumerable<MyApp.Models.Order>
#{
ViewBag.Title = "Index";
}
<h2>Orders Historic</h2>
<div id="orderDiv">
#using (Html.BeginForm("Export", "Historic", FormMethod.Get))
{
<p>
Generate Order with ClientID :&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp
#Html.TextBox("searchString")
<input type="submit" value="GENEREMOI" />
</p>
}
</div>
And my Export view :
#model IEnumerable<KrysGroup.Models.Order>
<table cellpadding="3" cellspacing="3">
<tr>
<td width="12%" align="center">
Client Name/ID
</td>
<td width="15%" align="center">
N° Order
</td>
OTHER TD....
</tr>
#foreach (var item in Model)
{
TimeSpan result = DateTime.Now - item.OrderDate;
if (result.Days < 31)
{
<tr border="1" bgcolor="#Odd">
<td> #Html.DisplayFor(modelItem => item.Username) </td>
<td> #Html.DisplayFor(modelItem => item.OrderId) </td>
<td>
<ul style="list-style-type:none; padding:0; margin:0">
#if (item.OrderDetails != null)
{
foreach (var o in item.OrderDetails)
{
if (o.Pack == null)
{
<li> #Html.DisplayFor(modelItem => o.Product.Name) </li>
}
else
{
<li> <text>Pack</text> #Html.DisplayFor(modelItem => o.Pack.Name) </li>
}
}
}
</ul>
</td>
OTHER TD...
</table>
So, in my view, I inform in a textbox a ClientID and when I click the button, it export in a file all the fields in my table with this ClientID.
I would like to automate this action, that is to say I would like write a method or something for, when I click on the button, it executes this export() method for each clientId it meet in my table.
I hope I was clear enough, sorry for my english..
Thanks for your answers, links, tips whatever.

Answer 1

You can write a partial view typed to a list of Id's that loads when you click the button.
So in the controller you have a method converts what you want and returns a view that is typed to the conversion of your model.
In your main view you have a div that will be populated with a partial view after the click-event of the original button.
#Ajax.ActionLink("Name", "NameOfTheAction", "NameOfTheController",
new { id = itemId },
new AjaxOptions { HttpMethod = "Get", UpdateTargetId = "divInMainView", OnSuccess = "Do Something (js)" },
new { html-props })
How to populate is up to you, in your view
