Silverlight recognizes three types of button controls: the familiar Button, the CheckBox, and the RadioButton. All of these controls are content controls that derive from ButtonBase. The ButtonBase class includes only a few members. It defines the obviously important Click event and adds the IsFocused, IsMouseOver, and IsPressed read-only properties. Finally, the ButtonBase class adds a ClickMode property, which determines when a button fires its Click event in response to mouse actions. The default value is ClickMode.Release, which means the Click event fires when the mouse is clicked and released. However, you can also choose to fire the Click event mouse when the mouse button is first pressed (ClickMode.Press) or, oddly enough, whenever the mouse moves over the button and pauses there (ClickMode.Hover). You ve already seen how to use the ordinary button. In the following sections, you ll take a quick look at the more specialized alternatives that Silverlight provides.

In this example, the XPath expression for BusinessEntityID is the wildcard character, *. The second column is defined as ',' + EmailAddress and the column is not given a name. Both of these columns are turned into inline content immediately below the row element, as shown in Figure 12-3. This is particularly useful functionality when creating lists within your XML data, or when your XML data conforms to a schema that looks for combined, concatenated, or list data in XML text nodes.

javascript OCR API - Stack Overflow
I see this is an old post, but the topic is still open and there are some new players now. You could use the OCR API from HP Haven OnDemand.

Like the HttpApplicationState type, the HttpSessionState may hold any System.Object-derived type, including your custom classes. For example, assume you have a new web application (SessionState) that defines a class named UserShoppingCart: Public Class UserShoppingCart Public desiredCar As String Public desiredCarColor As String Public downPayment As Single Public isLeasing As Boolean Public dateOfPickUp As DateTime Public Overrides Function ToString() As String Return String.Format("Car: {0}<br>Color: {1}<br>" & _ "$ Down: {2}<br>Lease: {3} <br>Pick-up Date: {4}", _ desiredCar, desiredCarColor, downPayment, _ isLeasing, dateOfPickUp.ToShortDateString()) End Function End Class Within the Session_Start() event handler, you can now assign each user a new instance of the UserShoppingCart class: Sub Session_Start(ByVal sender As Object, ByVal e As EventArgs) Session("UserShoppingCartInfo") = New UserShoppingCart() End Sub As the user traverses your web pages, you are able to pluck out the UserShoppingCart instance and fill the fields with user-specific data. For example, assume you have a simple *.aspx page that defines a set of input widgets that correspond to each field of the UserShoppingCart type and a Button used to set the values and two Labels that will be used to display the user s session ID and session information (see Figure 27-7).

The ordinary Button control is simple enough you click it, and it fires a Click event that you handle in code. But what about the other variants that Silverlight offers

The server-side Click event handler is straightforward (scrape out values from TextBoxes and display the shopping cart data on a Label type): Partial Class _Default Inherits System.Web.UI.Page Protected Sub btnSubmit_Click(ByVal sender As Object, _ ByVal e As System.EventArgs) Handles btnSubmit.Click ' Set current user prefs. Try Dim u As UserShoppingCart = _ CType(Session("UserShoppingCartInfo"), UserShoppingCart) u.dateOfPickUp = myCalendar.SelectedDate u.desiredCar = txtCarMake.Text u.desiredCarColor = txtCarColor.Text u.downPayment = Single.Parse(txtDownPayment.Text) u.isLeasing = chkIsLeasing.Checked lblUserInfo.Text = u.ToString() Session("UserShoppingCartInfo") = u Catch ex As Exception lblUserInfo.Text = ex.Message End Try End Sub End Class

As you saw in the previous examples, FOR XML PATH groups together nodes that have the same parent elements. For instance, the First, Middle, and Last elements are all children of the Name element. They are grouped together in all of the examples because of this. However, as shown in Listing 12-4, this is not the case when these elements are separated by an element with a different parent element. Listing 12-4. Two Elements with a Common Parent Element Separated SELECT p.BusinessEntityID AS "@ID", e.EmailAddress AS "@EmailAddress", p.FirstName AS "Person/Name/First", pp.PhoneNumber AS "Phone/BusinessPhone", p.MiddleName AS "Person/Name/Middle", p.LastName AS "Person/Name/Last"
