Hi eru,

The initializecomponent issue occur when either your namespace is wrong or partial class name is wrong. Here in your code, the XAML is pointing to "SilverlightDB.Page" where "SilverlightDB" is the namespace and the class it is pointing to is "Page". The code behind file it is using "MainPage". Hence it is unable to find the actual code behind to load the components.

Rename the entry in the XAML to point to "SilverlightDB.MainPage" and save the file. It will definitely work. Let me know.

First of all, your xaml is incorrect. Remove this "xml" from your xaml.

Next, are you looking for a sample on how to insert data into a database?

You have paster this code in your xaml.
But have you changed the name and namespace of your class file (the code behind file) to the same name i.e. SilverlightDB.Page?

here is code behind

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;

    public partial class MainPage : UserControl
        public MainPage()
          //  InitializeComponent();
        private void SubmitRegister_Click(object sender, RoutedEventArgs e)

            RegisterClient webservice = new RegisterClient();

            webservice.InsertDataAsync(txtFirstName.Text, txtEmailID.Text, txtPhoneno.Text, txtLoginName.Text, txtPassword.Text);
