My XAML Codefrom this page looks like this: <Page x:Class="ExampleApp.myPage2"> <Grid x:Name="Content" Height="651" Width="941" Background="White"> ... ... </Grid> </Page> I know that I can load a resource from a page with this Code: protected override DataTemplate SelectTemplateCore(object item, DependencyObject container) { var contentControl = (ContentControl)container; return (DataTemplate) contentControl.Resources

问题 I'm trying to bind a ContentControl's Content to a UserControl I have instantiated in my ViewModel. I cannot use the method with binding to a ViewModel and then have the UserControl be the DataTemplate of the ViewModel, as I need the Content of the ContentControl to be able to change frequently, using the same instance of the UserControls/Views, and not instantiate the views each time i re-bind.

问题 I'm currently trying to achieve the functionality of a tabcontrol with hidden tabs by using a ListView (as tabs) and a ContentControl with Binding the Content Property.

问题 I have this in XAML <ControlTemplate TargetType="{x:Type Button}"> <Image ...> </ControlTemplate> I want to achieve same in C# code. How can I achieve this? ControlTemplate ct = new ControlTemplate();.. Image img = new Image();.. Now how to assign this Image to Control template? Can we do this or Am I missing any concept here? 回答1: Creating template in codebehind is not a good idea, in theory one would do this by defining the ControlTemplate.VisualTree which is a FrameworkElementFactory.

问题 I am deserializing a XML file into a class and then trying to display some XAML (stored in a property in the class) in a ContentControl. Here is my XML: <CallSteps> <CallStep> <StepID>20</StepID> <StepName>Intro</StepName> <StepXaml> <![CDATA[<StackPanel xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:uc="clr-namespace:CallTracker.Library.UserControls.BaseUserControls;assembly=CallTracker.Library"> <uc:LabelValueControl Label="TestLabel" Value="356733" /> </StackPanel>

问题 I try to make a customized ListView which fills each list item with some stuff and an initial Checkbox if the concrete inheriting class wishes so. Currently no Checkbox is displayed so I guess my code of the ContentControl stuff is somehow erroneous. <UserControl x:Class="local:MyListView" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="some/path/here"> <ListView> <ListView.View> <GridView> <GridViewColumn>

问题 I am trying to create a dynamic UI for polynomial function. Since I do not know the order beforehand, I want to create it dynamically. I am setting my coefficient list as a items source of items control and planned to change data template based on the index. The template should work like this if (index > 1) { (coefficient text box) + *x ^ (index) + //Polynomial2 } else if (index == 1) { (coefficient text box) + *x + //Polynomial 1 } else if (index == 0) { (coefficient text box) //Polynomial }

问题 what is wrong about the following code? I get this error during compilation: The property 'TargetName' does not represent a valid target for the 'Setter' because an element named 'cc' was not found. Make sure that the target is declared before any Setters, Triggers or Conditions that use it. How do I have to refactor my code so I can compile it without error? I just want to switch a datatemplate with DataTrigger bound to a value in my PersonViewModel! <ContentControl x:Name="cc" Grid.Column=

问题 I am pretty new to WPF, (using it for 3 weeks now), so I might be missing something stupid or not understanding what I am doing! I am trying to create a modal type popup window that would cover either the whole application or current control it is in. I want this control to be semi transparent so the user can still see the content behind but not be able to use it.
