I am unable to enter the data into database.

Hello Friends,

I am a beginner in ADO.net. I have a simple form with three text field and a submit button. Now i am trying to enter the text field values into database. I have database name: "ashish" with a table name "ashish1". Now what i did, i created a connection through wizard. And that connection generate a connection string "Data Source=.\SQLEXPRESS;AttachDbFilename="C:\Program Files\Microsoft SQL Server\MSSQL.2\MSSQL\Data\ashish.mdf";Integrated Security=True;Connect Timeout=30;User Instance=True". And on botton event i am entering this code:

private void button1_Click(object sender, EventArgs e)
/*SqlConnection con = new SqlConnection();
con.ConnectionString = "Data Source=SQLEXPRESS;Initial Catalog=ashish;Integrated Security=True;Connect Timeout=30;User Instance=True";
string quary = "insert into ashish1(name, address, phone) values(@name, @address, @phone)";
SqlCommand cmd= new SqlCommand();
cmd.CommandText = quary;
cmd.CommandType = CommandType.Text;
cmd.Parameters.AddWithValue("@name", textBox1.Text.ToString());
cmd.Parameters.AddWithValue("@address", textBox2.Text.ToString());
cmd.Parameters.AddWithValue("@phone", textBox3.Text.ToString());
catch (Exception ed)

Now when i click upon submit button, system is showing me an error. Error message is:

System.InvalidOperationExection: ExecuteNonQuery: Connection property has not been initialized.
at System.Data.SqlClient.SqlCommand.ValidateCommand(String method, Boolean async)
at System.Data.SqlClient.SqlCommand.InternalExecuteNonQuery(DbAsyncResult result, String methodName, Boolean sendToPipe)
at System.Data.SqlClient.SqlCommand.ExecuteNonQuery()
at WindowsApplication1.form2.button1_click(...) in ..\form2.cs

Please guys guide me how do i insert the data.

Re: I am unable to enter the data into database.

For that I will do the following. In a table of the DB files are saved the personal taste of candidates. With the form xxx1 you can capture the person or change data. As can be seen, the fields are not numeric or delimited by apostrophes Boolean. Of course, it is essential to fill in all fields of the record. Of course, it may be that certain fields are required. These fields are required can be defined when we built our table using the database.
