PDF in MVC using Kendo Grid - asp.net-mvc

Question

I am using Kendo grid. In that grid first column is hyperlink column. If I click on each hyperlink, then the selected text of the hyperlink should be passed to the controller action. That hyperlink text is actually a pdf file name. So if a file name is is clicked on the grid ,then the same file should be opened in a tag is same page itself. Both the grid and tag to view PDf are in same page. How to do this?
Kendo grid: // This grid will be in Home.cshtml and also I splitted this into two . one will have this grid floating left and other will floating right with as follows
<object data=#url.action("GetPdf")></object>
#(Html.Kendo().Grid<Cutomers.Model.CustomerDataModel>()
.Name("grid")
.Columns(columns =>
{
columns.Bound(p => p.FileName).ClientTemplate( "/#= FileName #" );
columns.Bound(c => c.CreatedDate).Width(70);
columns.Bound(c => c.CreatedBy).Width(70);
})
.HtmlAttributes(new { style = "height: 350px;" })
.Scrollable()
.Groupable()
.Sortable()
.Pageable(pageable => pageable
.Refresh(true)
.PageSizes(true)
.ButtonCount(1))
.DataSource(dataSource => dataSource
.Ajax()
.Read(read => read.Action("Customers_Read", "Home"))
)
)
My controller:
public FileStreamResult GetPDF()
{
FileStream fs = new FileStream("D:/pdfSample.pdf", FileMode.Open, FileAccess.Read);
return File(fs, "application/pdf");
}
