Hi, If you are using ASP.NET Web Form then please add 3 textbox and a button. Now paste the below code in .aspx.cs button click event and put your DB connection string. This is how, you can add 3 values in a table. protected void btnInsert_Click(object sender, EventArgs e) { var cnnString = "Your DB ConnectionString"; var cmd = "insert into TableName values(@Name,@Address,@Phone)"; using (SqlConnection cnn = new SqlConnection(cnnString)) { using (SqlCommand cmd = new SqlCommand(cmd, cnn)) { cmd.Parameters.AddWithValue("@Name",txtName.Text); cmd.Parameters.AddWithValue("@Address",txtAddress.Text); cmd.Parameters.AddWithValue("@Phone",txtPhone.Text); cnn.Open(); cmd.ExecuteNonQuery(); } } }
