binding

问题 I am trying to host the same service inside the same website using two endpoints one HTTP and the other HTTPS. The problem is I can happily call one service (whichever I call first works) but then call to the other fails until I iisreset and try again. SO I can happily call both but one at a time until a process recycle. I have exhausted (or I think I have) all relevant Q&A and documents that I could find and none of them seem to help me. The level of documentation of MSDN regarding these

问题 I have an error dialog (shown simplified below). I display the Report object in a ContentControl to which I have defined a Template simpleErrorTemplate . There is a CheckBox on the Window that I would like to use to change the template to/from detailedErrorTemplate . What is the best way to achieve this? <Window x:Class="Core.ErrorDialog" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <Window.Resources>

问题 I remember reading a couple of weeks ago that it sometimes doesn't work inside templates, and I recently tried to bind things in two different windows and it couldn't find the name declarations, so I assumed that it was local to the namespace of the class and just bound by setting the datacontext instead. However, I'm really curious when I am able to use binding elementname and when I cannot, because it's far more convenient when it is possible. edit: In reading that article, I found this to

问题 I want that the SaveButton from my form to dissapear when the form is disabled. I do that this way: this.formStackPanel.IsEnabled = someValue; if(this.formStackPanel.IsEnabled) { this.saveButton.Visibility = Visibility.Visible; } else { this.saveButton.Visibility = Visibility.Collapsed; } Isn't there a way of binding those properties in the XAML? Is there a better way of doing that? 回答1: Yes. You should be able to bind the stackpanel's IsEnabled to your button's Visibility property. However,

问题 I'm using the WPF DataGrid to bind to a collection of a custom class. Using AutoGenerateColumns="True" in the grid XAML, the grid is created and populated just fine, but the headings are the property names, as one would expect. I tried specifying <Display(Name:="My Name")> from the System.ComponentModel.DataAnnotations namespace and that has no effect. I also tried <DisplayName("My Name")> from the System.ComponentModel name space but still the headings are not affected. Is there no way to
