Well it's complicated for everybody; but that's what being a developer is all about.

There are lots of controls. Can you be more specific as to what you are looking for?

Telerik [^]makes many different controls and DevExpress [^]is a collection of controls also. Have you been to their websites?

I have no idea what I am wrong. Needless to say it is giving me a compiler error "Error 1 'clsWebServices' does not contain a definition for 'FindAddress' and no extension method 'FindAddress' accepting a first argument of type 'clsWebServices' could be found (are you missing a using directive or an assembly reference?)"
What do I need to do to make this Web Method / Web Reference work properly? This is for a local Access .mdb file that resides under app_Data.
This is what I have under App_Code for clsWebSerices.cs:
using Microsoft.VisualBasic;
using System;
using System.Collections;
using System.Collections.Generic;
using System.Data;
using System.Diagnostics;
using System.Data.OleDb;
using System.Web.Services;
public class clsWebServices : System.Web.Services.WebService {
public clsWebServices () {
}
public class Service1 : System.Web.Services.WebService
{
[WebMethod]
public dsAddress FindAddress(string LastName, string Path)
{
string connectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=" + Path;
string commandText = "select * from tblAddressBook where LastName like '" + LastName + "'";
dsAddress DS = default(dsAddress);
using (var connection = new OleDbConnection(connectionString))
using (var command = new OleDbCommand(commandText, connection))
{
DS = new dsAddress();
var adapter = new OleDbDataAdapter(command);
adapter.Fill(DS);
}
return DS;
}
}
}
And for clsWebServices.asmx:
<%@ WebService Language="C#" CodeBehind="~/App_Code/clsWebServices.cs" Class="clsWebServices" %>
frmAddressBook.aspx:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="frmAddressBook.aspx.cs" Inherits="frmAddressBook" %>

<asp:TextBox ID="txtPhoneNumber" runat="server" BackColor="#FFFFCC"></asp:TextBox>
</div>
</form>
</body>
</html>
The code behind:
using System;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class frmAddressBook : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnFindLastName_Click(object sender, EventArgs e)
{
lblMessage.Text = "";
try
{
clsWebServices serviceObj = new clsWebServices();
dsAddress dsFindLastName = new dsAddress();
string TempPath = Server.MapPath("~/App_Data/AddressBook.mdb");
dsFindLastName = serviceObj.FindAddress(txtFindLastName.Text, TempPath);
if (dsFindLastName.tblAddressBook.Rows.Count > 0)
{
DataRow r = dsFindLastName.tblAddressBook.Rows[0];
txtFirstName.Text = r["FirstName"].ToString();
txtLastName.Text = r["LastName"].ToString();
txtEmail.Text = r["Email"].ToString();
txtPhoneNumber.Text = r["PhoneNumber"].ToString();
}
else lblMessage.Text = "No records found!";
}
catch (Exception ex)
{
lblMessage.Text = ex.Message;
}
}
}
I have tried to add a WEB REFERENCE in VS2008 and it says :
This web service is using http://tempuri.org/ as its default namespace.
Recommendation: Change the default namespace before the XML Web service is made public.
[WebService(Namespace="http://microsoft.com/webservices/")]
public class MyWebService {
}

The error message is quite clear, and also correct. The class clsWebServices doesn't contain a method called FindAddress. That method is defined on a nested class called Service1.
Either move the method to the outer class, or change the class you're creating:
clsWebServices.Service1 serviceObj = new clsWebServices.Service1();

Richard thanks for the insight. I cleaned up things a bit to this:
clsWebServices.aspx.cs
using System.Data.OleDb;
using System.Data;
using System.Web.Services;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
[WebService(Namespace = "http://localhost:51557/Week3Lab/clsWebServices.asmx/FindAddress")]
public class clsWebServices : System.Web.Services.WebService {
public clsWebServices () {
}
[WebMethod(Description = "This method call will get the LastName and return the Dataset.", EnableSession = false)]
public dsAddress FindAddress(string LastName, string Path)
{
string connectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=" + Path;
string commandText = "select * from tblAddressBook where LastName like "+LastName ;
dsAddress DS = new dsAddress();
using (var connection = new OleDbConnection(connectionString))
using (var command = new OleDbCommand(commandText, connection))
{
var adapter = new OleDbDataAdapter(command);
adapter.Fill(DS.tblAddressBook);
}
return DS;
}
}
frmAddressBook.aspx.cs
protected void btnFindLastName_Click(object sender, EventArgs e)
{
lblMessage.Text = "";
lblMessage.Text = txtFindLastName.Text;
try
{
clsWebServices serviceObj = new clsWebServices();
dsAddress dsFindLastName = new dsAddress();
string TempPath = Server.MapPath("~/App_Data/AddressBook.mdb");
dsFindLastName = serviceObj.FindAddress(txtFindLastName.Text.ToString(), TempPath);
if (dsFindLastName.tblAddressBook.Rows.Count > 0)
{
DataRow r = dsFindLastName.tblAddressBook.Rows[0];
txtFirstName.Text = r["FirstName"].ToString();
txtLastName.Text = r["LastName"].ToString();
txtEmail.Text = r["Email"].ToString();
txtPhoneNumber.Text = r["PhoneNumber"].ToString();
}
else lblMessage.Text = "No records found!";
}
catch (Exception ex)
{
lblMessage.Text = lblMessage.Text + ex.Message;
}
}
When I submit the FORM it has this in the submit :
<form id="form1" runat="server" action="clsWebServices.asmx/FindAddress" method="post">
I am getting this though as an error:
System.InvalidOperationException: Missing parameter: LastName. at System.Web.Services.Protocols.ValueCollectionParameterReader.Read(NameValueCollection collection) at System.Web.Services.Protocols.HtmlFormParameterReader.Read(HttpRequest request) at System.Web.Services.Protocols.HttpServerProtocol.ReadParameters() at System.Web.Services.Protocols.WebServiceHandler.CoreProcessRequest()

Why? If you want to call the service from the code-behind, you need to post back to the same page. Your form is trying to post directly to the service instead.
I haven't tried it, but posting to the service might work if you use client-side controls so that the names match the parameter names precisely. You can't use the server controls, because ASP.NET will mangle the names to make them unique. However, even if it works, the result isn't going to be something you want to display to the user.
If you want to call the service from the browser without posting back, you'll need to use javascript:

Okay. I got it working 100%. I was totally over-thinking things. I made some minor changes to part of the code and took out the form submit junk I had. Thanks again for your help.

To me the best way to store a list of strings a List<String>.
Simples really!
Cheers!

use String builder . it's best one store to string and then compare to string is very fast..
Another one
- List<string> slist = new List<string>();

I have a view for import batches (headers, not details), which a link to start a new import. When the user clicks that link, I want to invoke my Import action method. Inside that standard, synchronous action method, I want to start an asynchronous task, and then redirect back to another view. That view will monitor the progress of the async task with ajax calls and update the view so the user can follow the progress.
Everything I can find goes into too much complexity with async action methods etc. which is overkill for me in the prototyping phase.
Suggestions and critique of what I want to do will be most welcome.
