Try from this link: http://www.dotnetcurry.com/ShowArticle.aspx?ID=138In one video of learning Linq I saw this tag but not remember this perfectly. But I test this, also you can make table with your linq code.Have good time!

Try this code to import excel to Gridview:
using System.Data;
public partial class _Default : System.Web.UI.Page
{
DataTable dt = new DataTable();
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
//Check file is available in File upload Control
if (FileUpload1.HasFile)
{
//Store file name in the string variable
string filename = FileUpload1.FileName;
//Save file upload file in to server path for temporary
FileUpload1.SaveAs(Server.MapPath(filename));
//Export excel data into Gridview using below method
ExportToGrid(Server.MapPath(filename));
}
}
void ExportToGrid(String path)
{
OleDbConnection MyConnection = null;
DataSet DtSet = null;
OleDbDataAdapter MyCommand = null;
//Connection for MS Excel 2003 .xls format
MyConnection = new OleDbConnection("provider=Microsoft.Jet.OLEDB.4.0; Data Source='" + path + "';Extended Properties=Excel 8.0;");
//Connection for .xslx 2007 format
// MyConnection = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source='" + path + "';Extended Properties=Excel 12.0;");
//Select your Excel file
MyCommand = new System.Data.OleDb.OleDbDataAdapter("select * from [Sheet1$]", MyConnection);
DtSet = new System.Data.DataSet();
//Bind all excel data in to data set
MyCommand.Fill(DtSet, "[Sheet1$]");
dt = DtSet.Tables[0];
MyConnection.Close();
//Check datatable have records
if (dt.Rows.Count > 0)
{
GridView1.DataSource = dt;
GridView1.DataBind();
}
//Delete temporary Excel file from the Server path
if(System.IO.File.Exists(path))
{
System.IO.File.Delete(path);
}
}
}

One of the main visible problem is your Excel spreadsheet has sub tables (for example, Cargo Qty). In 'pure' html, this can be done using COLSPAN or ROWSPAN, but with the GridView, it's not that easy, unless you create sub gridviews, like this:
<asp:GridView runat="server" ...>
<Columns>
<asp:BoundField HeaderText="MyHeader" DataField="MyField1"... />
...
<asp:TemplateField HeaderText="MySubGridHeader">
<asp:GridView runat="server" ...> // need to databind this
<Columns>
<asp:BoundField HeaderText="MySubHeader1" DataField="MyField2"... />
<asp:BoundField HeaderText="MySubHeader2" DataField="MyField3"... />
</Columns>
</asp:GridView>
</asp:TemplateField>
</Columns>
</asp:GridView>
Otherwise I suggest you go for commercial packages which can display advanced grids, such as this one for example: SPREAD (note: I'm not affiliated and I have not tested it).
