Quick note on Web.config file

A quick note on Web.config file in the ASP.NET project. It is worth noting that the file is a XML File (read this for more info – )

One issue that hindered my process earlier was that the content in the value has special character it in, particularly, one of my SQL server’s password has a special character in it.

I would have to go and replace them accordingly. For instance, my password is <Password1& (note that < and ” is inclusive), i would have to change it to

Windows Phone 7 – Textbox On Focus Color

Was browsing around Stackoverflow and saw a question that someone asked, (WP7DEV) Textbox background changes when typing

Thought it will be useful for someone who needs it.

By default, a textbox on Windows Phone 7 will look at the one you see in the screenshot on the left, below, but when you were to focus on it, it will turn into slightly white-ish, as seen on the right.

Some of the scenarios for your development do not allow that and requires them to be the same. Written this quick guide in case someone needs it.

1. Attach a GotFocus event handler to the textbox you want to have the effect on.
2. Add this code in the method.

textBox2.Background = (SolidColorBrush)Resources[“PhoneTextBoxBrush”];
textBox2.BorderBrush = (SolidColorBrush)Resources[“PhoneTextBoxBrush”];

*Please remember to change textBox2 to the correct id of the textbox that you want the effect on.

For those of you who are curious where I get the Resources from, you can view a list of the available resources here :

Using Toggle Control to disable/enable idle detection – Windows Phone 7

Saw a question on Dream Build Launch on how can one use toggle control to disable / enable idle detection and from there, enable/disable it idle detection accordingly.

I believe he needed it in his setting page. Did up a quick demo.
















1. I used the toggle control from the silverlight toolkit for Windows Phone on codeplex (Can be found here : for the toggle control.

2. Do read this msdn article for

Things I did
1. Added the toggle controls in the toolkit into Visual Studio (if you have yet to do so)
2. Pull in the toggle controls and attached the checked event handler onto the control.
3. Add the following code (I included the method signature here).

private void toggleSwitch1_Checked(object sender, RoutedEventArgs e)

if (toggleSwitch1.IsChecked == true)
PhoneApplicationService.Current.ApplicationIdleDetectionMode = IdleDetectionMode.Disabled;
PhoneApplicationService.Current.ApplicationIdleDetectionMode = IdleDetectionMode.Enabled;

Remove Title Bar from your WPF application

Recently, one of my friends was asking me how can him remove the title bar from his WPF Application. He dont know what the keyword he can use, I thought its interesting so I am posting here so in case if any one needs it in the future.

There are a few ways to do it.
1. Do through coding ( Code Behind ).

this.WindowStyle = WindowStyle.None;

2. Do through XAML. Add in the WindowStyle attribute to the Window Tag
Window WindowStyle="None">

3. Editing through the properties ( Ultimately, this changes the XAML )

Detecting theme on Windows Phone 7

This blog post is going to teach you how do we detect if we are on dark or light theme on Windows Phone 7. I realised that this will be useful because I have quite some friends who are asking me about it because they didn’t get the right resources online. If you happened to come across a resource that asks you to get from App.xaml, that doesnt work anymore as its removed after the RC build.

Based on Theme Resources for Windows Phone, under Theme Visibility and Opacity.
By checking Resources, I am able to check if its Visible or Collapsed for the dark or White theme by doing this

Visibility isLight = (Visibility)Resources[“PhoneLightThemeVisibility”]; // for light theme
Visibility isDark = (Visibility)Resources[“PhoneDarkThemeVisibility”]; // for dark theme

Then we use if else to check,

if (isLight == System.Windows.Visibility.Visible)
//We are on light theme

Light Theme


if (isDark == System.Windows.Visibility.Visible)
//We are on dark theme

Dark Theme

Attached is a sample code to show how do I detect Windows Phone 7 theme, before the Mango buuild ( I am unsure if there is a change after Mango ).
