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 : http://msdn.microsoft.com/en-us/library/windowsphone/develop/ff769552(v=vs.92).aspx#BKMK_BrushResources

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 : http://silverlight.codeplex.com/releases/view/75888) 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;

AppHub had just created 22 scenario focused web pages for developers. It provides a comprehensive view of all the resources available for Windows Phone 7 development. I figured that this will be interesting and useful for developers like you and me.

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