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.
Explaination:
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.

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.
Resources
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;
else
PhoneApplicationService.Current.ApplicationIdleDetectionMode = IdleDetectionMode.Enabled;
}

Many a times, when we do a XNA game, we will want it to be full screen and hide the battery indicator. We will not want to show the battery indicator like this.
With Battery Indicator
You can change it to remove the battery indicator by adding this line of code at the constructor where the game is initialized.
graphics.IsFullScreen = true;
Without Battery Indicator
You can download and view the sample here.

Recently I blogged about Error reporting for Windows Phone 7 : Little Watson but when I was using it for the Slime Sweeper V2 , i realised its not as simple as copying and paste the framework over to XNA and use it. We have to introduce some extra stuffs.
I built the XNA version for it. Appreciated the help given by Konaju Games on MSDN forum here and Andy Pennell who have written the original version of Little Watson.
We have to add Microsoft.Phone and System.Windows references into the project. The codes are similar but we do not have native MessageBox.Show and Application.Current.UnhandledException in the project like what we have on Silverlight project and hence we have to add them differently to the project.
In the constructor of the game, we have to add this code.
Application.Current.UnhandledException += (s, e) =>
{
if (!System.Diagnostics.Debugger.IsAttached)
{
try
{
LittleWatson.ReportException(e.ExceptionObject, GetType().Assembly.FullName);
}
catch
{
// We do not want to throw exceptions in our exception handler
}
}
};
and as for MessageBox.Show, I am using Guide.BeginShowMessageBox method.

Guide.BeginShowMessageBox
You can download the sample code which I have built here, the button will crash the application and when you try to go into the application again from the emulator, a messagebox will appear :
