code-behind

问题 I’m learning C# and building a UI that reads and writes integers to an XML config file. The UI uses a variety of custom user controls. I have a 3 radiobutton user control that binds to a single int variable (control returns 0,1,2). The control uses an event to trigger the update. It looks at the 3 isChecked properties to determine the new int value. But I don’t know how to update the original binding value from the code behind. It's once removed so to speak because there are two binds..one in

问题 In xaml it is : <View:BaseWindow.Icon> /VBDAdvertisement;component/Images/logoVBD.png </View:BaseWindow.Icon> I want to convert it into code behind. Thanks 回答1: Something like myWindow.Icon = new BitmapImage(new Uri("/VBDAdvertisement;component/Images/logoVBD.png")); You may need to qualify the path more though.

问题 I've got some code-behind that opens like this: namespace MyNamespace { public partial class _Default : Page { public DropDownList DDL_Reporting_RunForDaily; public bool _retrievedData = false; I want to use _retrieveData in a session variable, so I'm setting it to false from the start.

But yes i have tick marked " Place code in separate file " checkbox when creating this website in VS 2010. Thanks in advance

Currently I've done this: if (parameter != null && parameter is System.Windows.Media.Animation.Storyboard) { if (!(bool)value) { (parameter as System.Windows.Media.Animation.Storyboard).Begin(); return Visibility.Visible; } else { (parameter as System.Windows.Media.Animation.Storyboard).Stop(); return Visibility.Collapsed; } } I
