Export excel data to sharepoint list in sharepoint 2010

Here i will given a simple way to export the data to sharepoint list from excel file which is in documnet library in sharepoint.The data table"Exceldata" has used to get the excel data then bind this data to SPlist.Here first we get the path of the excel file in documnet library ,then using this path in connection string.

string ExcelfileName = Path.GetFileName("http://url/Test.xls");
string ExcelileLocation = Server.MapPath(Excelfilename);                
String Con = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source="+ ExcelfileLocation +;Extended Properties=Excel 8.0;";  
OleDbConnection objCn = new OleDbConnection(con);  
DataTable ExcelData= new DataTable();
oleDbDataAdapter Oda = new OleDbDataAdapter("select * from[Sheet1$]", Con);   
oda.Fill(ExcelData); 
SPList ExcelDataList = w.Lists["ExcelDataList"];
for (int j = 0; j <= ExcelData.Rows.Count - 1; j++)
{
SPListItem ExcelDataistItem = ExcelDataList.Items.Add();
for (int i = 0; i <= ExcelData.Columns.Count - 1; i++)
{
string ColName = ExcelData.Rows[0][i].ToString();
ExcelDataistItem[ColName] = ExcelData.Rows[j][i].ToString();

SQL Server 2012:Complete details of New functions in SSIS

In this post i will give brief explanation about new functions in SSIS.In this version we have four new functions .Those are
LEFT:In previous versions there is no LEFT option in SSIS.In this version it will introduces as one of the string function In ssis and it will be use instead of SUBSTRING function.So by using this we can get left part of string

ex:SELECT LEFT(Full name, 3) 
FROM orders

REPLACENULL:It will use to replace the null values.

ex:REPLACENULL(city, "Hyderabad")

TOKEN:By using this function we can return a substring by using delimiters to separate a string into tokens

ex:TOKEN("Bhaskar developer"," ",1) 
give result as bhaskar

TOKENCOUNT:This function will give the count of tokens in the string which is already convert to token from string using delimiters

Ex:TOKENCOUNT("My name is bhaskar"," ")
The count this token is 4

Bind data to dropdownlist in Asp.net MVC4

In previous articles we have seen how to bind data to dropdownlist in gridview in asp.net,How to create entity data model in MVC,Give the reference to css/java script file in ASP.NET MVC,.In this post i will give an example for binding data to drop downlist with static data and dynamic data(From DataBase) in MVC.To assign the items to drop downlist statically,First we have to put the items into SelectListItem array  in controller.Then we can bind those items to drop down in View
Model:

using System.Web;
using System.Web.Mvc;
using System.Configuration;

namespace Dropdown.Models
{
public class Dropdwon
{
public SelectListItem[] sli { set; get; }
}
}

Controller:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using Dropdown.Models;

namespace Dropdown.Controllers
{
public class DropdownController : Controller
{
// GET: /Dropdown/
public ActionResult Index()
{
var sli = new[]{
new SelectListItem {Text = "India"},
new SelectListItem {Text = "US" },
new SelectListItem {Text = "UK" },
new SelectListItem {Text = "Australia" }
};
ViewData["ddlcountryname"] = sli;
return View(sli);
}

}
}

Index.cshtml

@{

    ViewBag.Title = "This is my test";

}

<h2>Bind data to dropdown list in mvc4</h2>

@Html.DropDownList("ddlcountryname")

Using Entity model To bind data:
I have used entity model to bind the data to dropdown from database.Whenever we create a connection we can get  model with our data base.Then we can write LINQ query to get the desired data.Finally we need to convert the data to SelectList from query data

using System;
using System.Collections.Generic;
using System.Data;
using System.Data.Entity;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using Dropdown.Models;

namespace Dropdown.Controllers
{
public class CityController : Controller
{
private Test_KrishnaEntities db = new Test_KrishnaEntities();
 
// GET: /City/

public ActionResult Index()
{
List x = new List(); 
var city = from contact in db.Contacts orderby contact.Name
                         select contact.Name;
x.AddRange(city.Distinct());
ViewData["ddlcountryname"] =new  SelectList(x);
return View();
}
}

}

Sqlserver 2012:Details about New T-SQL commands

In sqlserver 2012 come up with three new T-SQL commands.Those are TRY_CONVERT(),OFFSET / FETCH,FORMAT().

Detailed Description with Examples:
TRY_CONVERT():
The main advantage of using this command is  we can return NULL values with out exception even if the data type does not match in column.In previous versions when we try to get the numbers as char or chars to numbers we used to get exception.

SELECT TRY_CONVERT(INT,age) from table where ISNUMERIC(age) = 25;

OFFSET / FETCH:
The main thing here is to avoid fetching the entire data from table instead it only provides us up to the required limit.Previously this option is only available in MYSQL

SELECT * FROM emp ORDER BY name OFFSET 0 ROWS FETCH NEXT 5 ROWS ONLY;

FORMAT():
BY using this string function we can show the output in desired format.Here i have a simple example to get the money format

SELECT FORMAT(12345.00,‘c’,‘en-us’);

output:12,345.00

Description:
This is the basic concept of the data binding to data source controls in asp.net.Now i would like to explain and given example on bind data to drop down list in grid view,In this post i will explain how to bind the data to grid view example in asp.net.Here the stored procedure has been used to get the data from sql database.In the same way we can see how to call a stored procedure in this example

<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
<title>Bind data to gridview in asp.net</title>

protected void Page_Load(Object Sender, EventArgs E) 
{
SqlConnection con=new SqlConnection("Data Source=Test;Initial Catalog=binddata;Integrated Security=true")
SqlCommand cmd = new SqlCommand("fiilldocgridview", con);
cmd.CommandType = CommandType.StoredProcedure;con.Open();
SqlDataAdapter ad = new SqlDataAdapter(cmd);DataSet ds = new DataSet();
try
{
da = new SqlDataAdapter(cmd);
da.Fill(ds, "DoctorsTable");
grvdoc.DataSource = ds;
grvdoc.DataBind();
