Auto Complete In MVC.
1.Write Code in Aspx Page As Below:-
2.Add JavaScript As Below
function SearchData() //eVERY TIME IT GO TO DATABASE
{
//where Home IS Controller And Search Is Method,SearchValue IS argument
$.getJSON("/Home/Search",
{ SearchValue:document.getElementById("listSearch").value},
function(result)
{
$("#SearchResult").empty();
$.each(result, function(i,temp) {
$("#SearchResult").append("
");});
});
}
var NameList;
$(document).ready(function()
{
//where Home IS Controller And Search Is Method,SearchValue IS argument
$.getJSON("/Home/Search",
{ SearchValue:""},
function(result)
{
NameList=result;
$.each(NameList, function(i,temp) {
$("#SearchResult2").append("
");});
});
});
function Search1() //IT DO AT LOCAL
{
$("#SearchResult2").empty();
var listSearch2=document.getElementById("listSearch2");
var txt=new RegExp(listSearch2.value,"i");
$.each(NameList, function(j,temp) {
if(temp.EmployeeName.search(txt)!=-1)
{
$("#SearchResult2").append("
");}
});
}
3. Code In Controller Will Be like This:-
{
string EmpNameList = "";
List<Employee> li = new List<Employee>();
EmployeeDAL empDal = new EmployeeDAL();
li = empDal.SearchEmployee(SearchValue);
return Json(li);
}

SQL Data Base Connection in C#
1. Connection with Your Database in Your Code, Data source is IP of data server:-
SqlConnection conn;
conn = new SqlConnection("Data Source=192.168.100.44;
Initial Catalog=DataBaseName;
Persist Security Info=True;
User ID=scoat;
Password=tiger");
conn.Open();
1.1 Connection Using WebConfig, Add this in webconfig:-
<connectionStrings>
<add name="SampleConnectionString"
connectionString="data source=192.168.100.44;
Initial Catalog=DataBaseName;
Persist Security Info=True;
User ID=scoat;
Password=tiger" providerName="System.Data.SqlClient"/>
<connectionStrings>
1.2 Add This In your code:-
SqlConnection conn = New SqlConnection
(ConfigurationManager
.ConnectionStrings["SampleConnectionString"].ConnectionString);
2.Spiecify store procedure Want To Use:-
SqlCommand cmd = new SqlCommand("ProcedureName", conn);
cmd.CommandType = CommandType.StoredProcedure;
3.Pass Parameter To Store Procedure:-
SqlParameter parameterObj = cmd.Parameters.Add("@ProcedureVariable",SqlDbType.Int);
parameterObj.Value = DataToPass;
4. Execut Procedure And Close Connection:-
SqlDataReader thisReader = cmd.ExecuteReader();
thisReader.Close();
conn.Close();
