Beginners Guide to Silverlight 4 PathListBox Control (Part–II)

In my previous article “Beginners Guide to Silverlight 4 PathListBox Control (Part-I)” I described about creating your very first PathListBox control in your Silverlight application followed by creating a Circular path to position the items in the circular edge. From that article, I think you are now familiar with it.

 

In this post, I will demonstrate you guys how to animate the items in a specific direction. This not only guide you for animation in PathListBox but also will help you understanding the StoryBoard creation (if you are very new to Silverlight). Read the whole article and at the end don’t forget to leave your comments.



Beginners Guide to Silverlight 4 PathListBox Control (Part–I)

Have you ever heard of PathListBox introduced in Silverlight 4 as Expression Blend 4 namespace? Yes, it is a new control added in the “http://schemas.microsoft.com/expression/2010/controls” namespace. You can use this to position your data, text, images or other controls in the way of a single or multiple path controls. You can use your jig-jag path to set your contents or you can use circular or rectangular path to organize your content.

In this article, I will guide you to understand the functionality of this control. Also, I will guide you step-by-step to create your first PathListBox control demo application. Here we will create the above two samples where the collection of texts will position them in proper location on the edge of the circular path.

 

Readout the complete post to learn about it and at the end, if you have any queries or comments, please let me know. I will try to answer your queries as soon as possible.


How to pass values to Silverlight application from ASPX page using InitParameter?

Here I will discuss on the InitParams and tell you how to use it to pass value from your .aspx page to your Silverlight application. Read the complete post and if you have any queries, don’t hesitate to ask me.


How to use new Rupee Symbol of India in Silverlight?

File:Indian Rupee symbol.svgIn July 2010, Indian Cabinet selected a new Symbol for the Indian Rupee which looks like as the snapshot shown at the left side. In this post, I will describe you how to integrate the same symbol in Silverlight application.


As the Unicode is not present for that till now, hence we need to use some font to write the letter using that. Fordian Technologies has the font and you can download it from their official Blog. The latest version of the font is available here: Rupee Font Version 2.0.


Let us have a quick tutorial on it to create a Silverlight application with the new Rupee Symbol of India in it.


How to Create a Silverlight OOB Installer Wrapper UI Library?

Before starting with the next part of the discussion, let me ask you some questions. Are you a Silverlight developer? If “Yes”, how many times you create a Silverlight Out-of-Browser application? For that, how many times you create an UI and write code to instruct the user to install the application as OOB application. I think the answer will be “Many Times”.

To solve this, we will create a Custom UI Wrapper (like the above snapshot) which will have all the codes necessary to guide the user. Once this is done, we don’t have to write the same installation code again and again over the applications. Read through the description and don’t forget to leave your comments and suggestions.

Silverlight 4: Text to Speech application using COM API

imageHave you ever heard of Text to Speech engine? “Yes” I think. Yes, it is not a new thing in the Computer World. It was available since Windows 98 (as much as I can recall) but it is completely new in Silverlight. You can now use the Silverlight application to give an API call to the SAPI Engine which will convert the text to voice. Sounds Good? This is achievable using the COM APIs only.

 

Here I will describe you how to use COM API to give a TTS call to the SAPI Engine. After reading this topic here, you will be able to write your own code to develop your own application having the Text to Speech functionality in Silverlight 4.


Text Trimming in Silverlight 4

Have you ever tried Trimming your Text in Silverlight 2 or Silverlight 3? If yes, just recall the lines of code you wrote for trimming your text content and showing an Ellipsis (i.e. “…” three dots) at the end of the text. If you didn’t try it earlier, then just imagine what you have to do and how you will do. Also imagine the no. of lines you have to write. Confused smile

In this post, I will show you how I can implement this feature the easy way. Stop!!! I will not write here a huge code nor I will use any library to do that. Microsoft has added this functionality in Silverlight 4. You just have to set the Enum value to the TextBlock property. Surprised smile Wao!!!

So, how to do that? Let us try it.

A Simple Application using Silverlight Physics Helper Library

Recently I was interested to work with the Physics Helper for Silverlight. I saw couple of demos on net which uses the Physics library for Silverlight to create good animations with Friction logic. Yeah, friction. You can drop a ball on a surface which will bounce over that surface. I found it very interesting and thought to create a Simple Demo for it.

Here I will demonstrate you creating a Sample Application using Expression Blend. You don’t have to write a Single line of Code using Visual Studio. Surprised smile Is it? Yes, lets start doing that.

Silverlight 4: Interoperability with Windows 7 Taskbar using COM

Microsoft released Windows 7 last year which has lots of functionalities including a nice UI. Among those features one of the most user friendly feature is Pin/Unpin application to Taskbar. You can develop WPF or Windows Forms applications in which you can implement this feature. But do you know that this is also possible in Silverlight? Yes, Silverlight 4 has the power to talk with any other application using the COM API. You can read one of my earlier article [Silverlight 4: Interoperability with Excel using the COM Object].

In this Article I will show you how we can talk with the Windows 7 Taskbar. Read the complete Article and provide your feedbacks or suggestions.



Silverlight 4: Interoperability with Excel using the COM Object

Silverlight 4 has the capability of accessing the COM object using the COM API. You can access any program installed in your PC using those APIs in Silverlight. You can open Notepad, Word, Excel or Outlook from Silverlight application.

 

Here I will demonstrate you the step-by-step tutorial on opening an Microsoft Excel book followed by data sharing between the Silverlight application and the Excel Sheet. Here we will use a DataGrid which will load some customer information. Then we will pass the data to the Excel Sheet and then we will modify the data in the external application (i.e. inside the Excel sheet). You will see that, the modified data will reflect automatically to the Silverlight Application.

Drag and Drop Operation in Silverlight ListBox

In this article, I am going to discuss with you regarding the Drag and Drop functionality inside a Silverlight ListBox control. This article will also cover the Drag and Drop operation between two ListBox control. We will use here the Silvelright 4 Toolkit to implement the feature.


Drag & Drop functionality is not present in Silverlight ListBox by default. Hence, there was a big problem implementing the feature. We had to write a huge code for this feature. But using Silvelright Toolkit you can do it very easily. You can download the Silverlight 4 Toolkit from the CodePlex Silverlight Toolkit site.


How to work with the Silverlight BusyIndicator?

Silverlight BusyIndicator is not a new thing in Silverlight. It was first added in Silverlight 3 Toolkit in November 2009 release (if I am not wrong). In this post I will describe about this for those who wants to know about it.

So, What is this Busy Indicator? Busy indicator is a tool which you can add in your Silverlight application to show a loading indication to your user while saving some sort of operation in database. Generally it is useful when you calling your WCF Service to store something in server or retrieving some data from server.


Silverlight Tutorials Chapter 3: Introduction to Panels

In my last chapter i.e. "Silverlight Tutorials Chapter 2: Introduction to Silverlight Application Development" we discussed on how to create a new Silverlight project, the structure of the project solution and later in this chapter we discussed on UserControls and various ways of development.

Command Binding in Silverlight 4 (Step-by-Step)

Silverlight 4 now came up with the support of Command Binding. Using Command binding you can easily develop your Silverlight MVVM (Model-View-ViewModel) applications where your view will not know about data. In this article, I will describe you the Command binding feature in Silverlight 4 Step-by-Step.

In this example, I will create a Customer View which will load the customer information from the code behind once we click the button “Load Customers”. The button will have a command associated with it to load the records instead of loading on click event. This ensures that the view will have less code & no relation with the data.
