can anyone tell me how to connect to sql database using c# and do simple transactions such as insert update delete and search ...but it shud be fully code based.

if possible please provide a sample.....

Friend, if you search on MSDN you'll find a lot of articles there. and you can post here specific question say, when you connect on SQL Server your application releases exception lmlmlma, so the question is "what's the error, friends..."
Best of luck with http://msdn.com

Just as MSDN is a fine source of information so is Google. Typed in ADO.NET, look what I found!

Hi,

First add Using System.SqlClient; namespace to your cs file.

Then write connection string like this

//Connection String
SqlConnection conn = new SqlConnection("data source=<NameOfYourSqlServerInstance>;Initial catalog=<NameOfYourDataBase>; username = <UserName>; password =<Password>;Integrated Security=True");

//Insert Method
SqlConnection conn = new SqlConnection("data source=<NameOfYourSqlServerInstance>;Initial catalog=<NameOfYourDataBase>; username = <UserName>; password =<Password>;Integrated Security=True");
SqlCommand cmd = new SqlCommand("InsertQuery",conn);
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();

//Update Method
SqlConnection conn = new SqlConnection("data source=<NameOfYourSqlServerInstance>;Initial catalog=<NameOfYourDataBase>; username = <UserName>; password =<Password>;Integrated Security=True");
SqlCommand cmd = new SqlCommand("UpdateQuery",conn);
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();

//Delete Method
SqlConnection conn = new SqlConnection("data source=<NameOfYourSqlServerInstance>;Initial catalog=<NameOfYourDataBase>; username = <UserName>; password =<Password>;Integrated Security=True");
SqlCommand cmd = new SqlCommand("DeleteQuery",conn);
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();
