tabitem

问题 I have a TabControl, and I apply a style to it in order for my TabItems' header to have no background nor border. My problem is that if I add a trigger for the selected one, the corresponding panel get styled as well. So if I choose to set the selected TabItem's foreground to Red, the panel's textblocks become red as well. Fun fact: it doesn't apply to Labels. I'm quite lost. Here's the XAML, that tests pretty fast in Kaxaml: <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml

问题 This is an attempt to expand on this question. In my WPF program I've been cloning tabItems by using an XamlWriter in a function called TrycloneElement . I originally found this function here, but the function can also be viewed in the link to my previous question. Now that I am beginning to worry about functionality inside my program, I found that the TrycloneElement function does not replicate any code-behind functionality assigned to the tabItem that it is cloning. Because of High Core's

问题 i have a Tabcontrol with Datatemplate for its TabItems and a ItemContainerStyle for the style of the TabItem. The TabControl: <TabControl Name="MainTabCtrl" Margin="0" Padding="0" BorderThickness="0" Background="Transparent" IsSynchronizedWithCurrentItem="True" ItemsSource="{Binding Path=TabViewModels}" ItemTemplate="{StaticResource ClosableTabItemTemplate}" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" ItemContainerStyle="{StaticResource ContainerStyle}"> The

问题 I am testing the shinydashboard package and I just can't figure out what is happening in a particular case. My dashboard has 4 tabItems (sorry it's in Dutch): Programma Deelnemers Notulen Overige The dashboard loads properly, but the content of tabItem four ("Overige") is shown beneath the content of "Notulen". The code of the App is as follows: library(shiny) library(shinydashboard) library(markdown) library(DT) # Simple header -----------------------------------------------------------

问题 I have the need to clone all of the contents of a tab to reflect the current state of a WPF TabItem, fully preserving all the bindings. The requirement is that each Tab should function independently with its own group of identical controls. I've so far only managed to create blank tabs. MSDN suggests this isn't possible. Seems like pretty basic functionality for MS to miss, so is this possible? // locate the TabControl that the tab will be added to TabControl itemsTab = (TabControl) this

问题 I have created TabItems in silverlight where each tab display some text. When i change the text then it show asterisk at the Header of TabItem with header name. Now what i want to achieve is : suppose i made a change on the current TabItem text display then when i switch from the one tab to another tab item then it must show a pop up saying "do you wanna save the changes done ?" Does silverlight provide any facility in TabItem to notify when there is change in the TabItem (I mean when

问题 All, I am adding a TabItem to a TabControl dynamically using MVVM. The new TabItems load fine, but I want the added tab to gain focus automatically. That is, I add a tab and I do not want to have to click on that tab to give it focus. The XAML for the TabControl look like <TabControl ItemsSource="{Binding Path=Workspaces}" IsSynchronizedWithCurrentItem="True" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"

问题 I'm sure there is something simple that I am missing, but I must confess that at this point I am at a loss. I am programmatically adding TabItems to my main TabControl, one for each account that the user chooses to open. Before creating and adding a new TabItem I would like to check if the user already has the account open in another tab. I do not want to end up with two identical tabs open. Here is the code that I originally wrote. Hopefully it gives you an idea of what I am trying to

问题 I have a TabControl. The header of each TabItem contains a StackPanel with an icon and a Label. <TabControl> <TabItem> <TabItem.Header> <StackPanel Orientation="Horizontal"> <Image Source="/LoginPanel;component/Icons/icoLogin.ico"</Image> <Label VerticalContentAlignment="Center">Login</Label> </StackPanel> </TabItem.Header> </TabItem.Header> <!--some further code here--> <TabItem> <!--some further code here--> <TabControl> Each icon in each non-selected TabItem is displayed as expected. The

问题 I have a TabControl with many TabItems binding to a ViewModel that has properties for each TabItem's Visibility. <sdk:TabControl> <sdk:TabItem Name="Inventory" Header="Inventory" Style="{StaticResource TabItemStyle}" Visibility="{Binding Permissions.Inventory, Converter={StaticResource PermissiveVisibilityConverter}, ConverterParameter='Viewer'}" DataContext="{Binding VM}" /> </sdk:TabControl> All TabItems are defaulted to a Visibility of collapsed. But when the VM changes a TabItem to
