Import Excel To Datagrid

Note: If you want to give client upload facility, than first upload the file to the server. Next call the excel file from the following server location.

private void btnImportExcelToGrid_Click(object sender,
System.EventArgs e)
{
String strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" +
"Data Source=C:\\Book2.xls;" +
"Extended Properties=Excel 8.0;";

DataSet ds = new DataSet();
//You must use the $ after the object
//you reference in the spreadsheet
OleDbDataAdapter da = new OleDbDataAdapter
("SELECT * FROM [Sheet1$]", strConn);

//da.TableMappings.Add("Table", "ExcelTest");

da.Fill(ds);
DataGrid2.DataSource = ds.Tables[0].DefaultView;
DataGrid2.DataBind();
}
