Custom module with possibility to add modules into module to create an expander module in DNN 9.2

阅读更多关于 Custom module with possibility to add modules into module to create an expander module in DNN 9.2

问题 I'm using DNN 9.2 and searching for a possibility to create an own module that will work like the Atlassian Confluence's Expander Macro where I could add additional content. In my case I want to add other modules, which will be visible if the parent is expanded and hidden if the parent is collapsed. I thought about to use a Pane control in my module to place several other modules into it. It is an approach that imitates the Evoq's Grid module functionality, but with the additional

Collapse all the expanders and expand one of them by default

问题 I have multiple expanders, and I was looking for a way to collapse all others the expanders when one of them is expanded. And I found this solution here XAML: <StackPanel Name="StackPanel1"> <StackPanel.Resources> <local:ExpanderToBooleanConverter x:Key="ExpanderToBooleanConverter" /> </StackPanel.Resources> <Expander Header="Expander 1" IsExpanded="{Binding SelectedExpander, Mode=TwoWay, Converter={StaticResource ExpanderToBooleanConverter}, ConverterParameter=1}"> <TextBlock>Expander 1<

Simulink学习——弹球仿真三维动画模型（Simulink3D演示动画学习01）

阅读更多关于 Simulink学习——弹球仿真三维动画模型（Simulink3D演示动画学习01）

前有一期我们学习了如何进行物理世界的简单建模仿真，如弹球仿真 https://onebigsoap.blog.csdn.net/article/details/108503788 ，其中可以看到弹球的高度变化等信息。虽然数据能看到小球的高度和速度变化，但是终究是不那么直观的。因此接下来我打算进行一些Simulink动画的学习，毕竟很多时候需要动画来演示仿真结果。这一期我们先来试试为弹球仿真做一个动画来制作一个简单动画演示。模型建立这里就是弹球仿真的模型简单描述：这里我们主要需要使用Simulink® 3D Animation™工具箱中的各种模块。弹球仿真属于比较简单的模型，这里我们只需要使用一个VR Sink模块。创建VR Sink模块后，打开它会出现如下对话框，点击New创建我们的模型，或者是Browse读取已有的模型。点击New后会出现一个编辑器，然后点击file，从已有模板创建，这里我们来从已有的模板上创建我们的动画模型，demo中有个小球的模型可以参考。创建好的模型如下，模板做的比较完整，这里需要改动的不多。动画模型保存后，回到VR Sink对话框，可以看到右边多出了一些可选的参数，这里我理解center为小球中心因此Position应该输出到这个参数吧，先设置center为输入接口（后面发现是不对的，后面有演示）：

问题 I am using an Expander for showing units and chapters of a book. I am able to show the units as the Expander.Header , but the chapters under the unit is again a list. I tried like below but chapters are not able to view on UI. XAML <StackLayout BindableLayout.ItemsSource="{Binding AllItems,Mode=TwoWay}"> <BindableLayout.ItemTemplate> <DataTemplate> <Expander ExpandAnimationEasing="{x:Static Easing.CubicIn}" ExpandAnimationLength="500" CollapseAnimationEasing="{x:Static Easing.CubicOut}"

WPF - How to get only one expander expanded at any one time

阅读更多关于 WPF - How to get only one expander expanded at any one time

问题 I've got a StackPanel with a group of expanders in, how do I set it so that only expander is expanded at any one time? Cheers AW 回答1: I didn't really want to do it like this as it required putting code (C#) in the class behind file for the window (I'm trying to avoid this completely by use of ViewModels etc). Ideally I would have described this in XAML. I hooked up every Expander 'Expanded' event I was interested in and did the following: private void HandleExpanderExpanded(object sender,
