问题 I am attempting to adapt a Windows Metro-style app sample slightly by binding the title text to a property defined in code-behind, but I can't seem to get it to work. Reading the blog post titled Bind from XAML to property defined in code-behind, I am trying out "Solution 1". Here is my XAML source (simplified): <UserControl x:Class="... .MainPage" x:Name="UserControlSelf" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

问题 I observe very strange exception handling behavior in any Windows 8.1 (WinRT) application.

Sometimes debugger shows it is common Exception but application works as it would be

问题 i am trying to set the slider control to value from text block's text property through {Binding} on XAML. <Slider ValueChanged="slider_ValueChanged_1" Value= "{Binding ElementName=ComponentTextBlockValue,Path=Text}" StepFrequency="25"/> Do i need an converter to set the slider's value .

Otherwise, how could the apps of Windows Phone 8 using the

问题 I'm trying to merge multiple Images into one image.
