Getting any error message?
before doing cmd.executeNonQuery get the sql statement and try to run in sql server
so you will come to know any syntax error or somethng.

Improper SQL statement.

cmd.CommandText = "INSERT INTO contactus1(Name,Telephone,Email,Enquiry) values ('" + TextBox4.Text + "','" + TextBox3.Text + "','" + TextBox2.Text + "','" + TextBox1.Text + "')";

Use Parameters instead of hard-coded sql statement.

SqlCommand cmd = new SqlCommand();
 cmd.CommandText = "INSERT INTO contactus1 (Name,Telephone,Email,Enquiry) values (@name,@tel,@email,@enq)";
 cmd.Connection = conn;
 cmd.Parameters.AddWithValue("@name",TextBox4.Text);
 cmd.Parameters.AddWithValue("@tel",TextBox3.Text);
 cmd.Parameters.AddWithValue("@email",TextBox2.Text);
 cmd.Parameters.AddWithValue("@enq",TextBox1.Text);

Check the following criterias

1. First check the UserId you are using to connect to SQL Server has got enough privileges to peform insert action.

2. Check the data length of all the columns. Check whether your data fits within the specified data limit. If not increase the datalength and try again.
