I heed to create wizard and in the wizard I have tab control which have to call to the user control according to the context,I need to create the wizard which will able to invoke
different pages according to the user selection ,currently I call to the pages as follows which I think is not the right way,any Idea how should I do it via code (not in the xaml )i.e. according to some decision invoke the suitable page to the tab control.
this is the xaml:
<Border Grid.Column="1" Name="MainBorder">
<TabControl x:Name="MainTabControl" Height="638" VerticalAlignment="Bottom">
<TabItem Visibility="Collapsed" >
<Frame Source="page1.xaml" />
</TabItem>
<TabItem Visibility="Collapsed" >
<Frame Source="page2.xaml"/>
</TabItem>
<TabItem Visibility="Collapsed" Header="Step 3">
<TextBlock Text="Page 3"/>
</TabItem>
<TabItem Visibility="Collapsed" Header="Step 4">
<TextBlock Text="Page 4"/>
</TabItem>
</TabControl>
</Border>
UPDATE
I was tried in the main window like the following without success
create new tab by code and add to it the page 1 and then add it to the MainTabControl
TabControl tabControl = new TabControl(new Page1());
MainTabControl.add..
.
there is no add in the main tab control
For this scenario, I would use a Frame rather that tabs. The frame allows you to manage the flow of it's content via the NavigationService. You can use Uri's to display a page via the Frame.Source property, or a FrameworkElement via the Frame.Content property. Both are DependencyProperties and can therefore be bound to.
Paul Stovel wrote an excellent blog on this called WPF Navigation. Everything you need to create a wizard from a frame can be found in this blog, including passing values between pages and templating of the Frame to simply handle the display of navigation buttons.
I would agree with Mark, it is a lot easier to use NavigationWindows than TabControls.
I've worked on a lot of interfaces like this and written up some of the basic things with,
WPF Wizards, Part 1
WPF Wizards, Part 2
Then more recently I worked out how to get the styling just right
Styling Wizards
In fact I've released the styling and examples as open source at
WinChrome
There is some simple example code including use of a navigation list to the left with,
WinChrome.Win7Demo
Hope this helps

I'm using dragablz:TabablzControl in a project of mine and I have the need of hide/show some tabs dinamically.
The fact is the control is not respecting the property Visibility of the TabItem.
I've tried with and without binding, like this:
<dragablz:TabablzControl Grid.Row="2" BorderThickness="0" FixedHeaderCount="20">
<TabItem Header="Additional Info" Visibility="{Binding ShowAdditionalInfoTab, Converter={StaticResource BooleanToVisibilityConverter}}">
<controls:AdditionalInfoControl />
</TabItem>
<TabItem Header="Additional Info" Visibility="Collapsed">
<controls:AdditionalInfoControl />
</TabItem>
</dragablz:TabablzControl>
But none is working. Change the "FixedHeaderCount" does not affect the result.
The tab remains always visible.
Is there any other way that I can achieve the result I need?
I've received a response from the development team, and I'm leaving it here for anyone who has the same problem.
Yeah, obviously there’s since changes to the standard tab control to support all of the extra features, and currently that’s not supported. You’d have to temporarily remove your hidden item from the source.
I would like to know if there's a way to implement a responsive Master/Detail page using only one. What I want is something exactly like the Project here:
https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/XamlMasterDetail
Except for the detail that instead of using two pages and navigating from one to another I would only use one page.
Is there a way to do it? If so, could you link me a working example?

After going through the project, I found it implemented a responsive master/detail experience based on the size of the screen. When the app view is sufficiently wide, the master list and detail view should appear side by side in the same app page. However, on smaller screen sizes, the two pieces of UI should appear on different pages, allowing the user to navigate between them. From my point of view, I think this is a good solution for implementing a responsive master/detail experience.
Is there a way to do it? If so, could you link me a working example?
The project already shows how to implement responsive Master/Detail in UWP using only one page, but it implements more and that makes it a little complex to understand. So I make a simple example which directly shows how to implement responsive Master/Detail in UWP using only one page.
Following is the main steps:
First, create a ListView to show master information in xaml page:
<!--Master VIEW-->
<ListView x:Name="ItemListView" Margin="0,0,0,8">
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel HorizontalAlignment="Left" Margin="10,8,0,0">
<TextBlock Text="{Binding Title}" FontSize="25" Width="400" />
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
Second, specify the details view that shows the details item related to the selection on the master list in the same xaml page:
<!--DETAILS VIEW-->
<StackPanel Grid.Column="1" x:Name="ContentPanelDetail" Margin="10,0,0,0" DataContext="{Binding SelectedItem, ElementName=ItemListView}">
<TextBlock Text="{Binding Title}" MaxHeight="80" FontSize="30" HorizontalAlignment="Left" Margin="0" />
<TextBlock x:Name="DetailTextBlock" FontSize="35" Text="{Binding Content}" HorizontalAlignment="Left" Margin="0,18,40,0" Width="500" Height="Auto" TextWrapping="Wrap" />
</StackPanel>
Then, set the ItemsSource for the ListView in code behind:
public MainPage()
{
this.InitializeComponent();
//set the ItemsSource for the ListView
ItemDetails messageData = new ItemDetails();
ItemListView.ItemsSource = messageData.Collection;
ItemListView.SelectedIndex = 0;
}
Last but not least, put Master View and Details View into a SplitView and use VisualStateManager to make it more responsive.
Here is the simple example and the output for your reference.
To implement Master/Detail pattern on your page, you don't have to do it yourself. Instead you can use MasterDetailsView control from UWP Community Toolkit, it does a lot work for you + it is well documented.
Note: For details section of the control, do not set background to null (NoSelectionContent will be visible).
I currently have a tab control containing multiple tab items, where each tab item contains different custom user control. I would like the tab headers to turn red when the associated tab contains a validation failure. My validations are implemented as ValidationRules on the appropriate bindings (moving to IDataError or another validation approach is not a feasible solution). Each tab specific control tracks it's errors through the bubbling ValidationErrorsEvent and exposes a count.
I am currently using x:Name on the tab specific controls & ElementName in the TabItem headers to bind the count exposed by the tab specific controls to the color of the text in the header (via a converter).
<TabControl>
<TabItem>
<TabItem.Header>
<TextBlock Text="Tab 1" Foreground="{Binding Errors.Count, ElementName=_tabOne, Converter={StaticResource ErrorCountToColorConverter}}" />
</TabItem.Header>
<AdornerDecorator>
<my:CustomTabOneControl x:Name="_tabOne" />
</AdornerDecorator>
</TabItem>
<TabItem>
<TabItem.Header>
<TextBlock Text="Tab 2" Foreground="{Binding Errors.Count, ElementName=_tabTwo, Converter={StaticResource ErrorCountToColorConverter}}" />
</TabItem.Header>
<AdornerDecorator>
<my:CustomTabTwoControl x:Name="_tabTwo" />
</AdornerDecorator>
</TabItem>
</TabControl>
Due to the lazyness of WPFs tab control, the validation of each tab does not occur until it is opened. As such the headers for tabs containing invalid fields do not turn red until the tab has been opened (after that they remain correct).
Can anyone suggest a way of resolving this issue, or an alternative approach to achieve the same tab highlighting?
Have a look at this post and answer; it is a lot of work and possibly maintenance but it does work by using a multitrigger that sets the header template based on the HasError property of the controls. Unfortunately it requires you to add a condition to the trigger for each control that should influence the state of the header.
You could try combine this with the answer to this post: Detecting WPF Validation Errors
that walks the visual tree to find Validation Errors. Thereby making it dynamic and less dependent on maintaining the trigger conditions when building the UI.
I'm looking for a way to create an application layout for a little tool that looks like the ESET Antivirus UI:
I thought, that I take a TabControl and do a complete Restyling on this whole thing. I created a basic tab layout:
<Grid Background="White" Grid.Row="1" >
<TabControl TabStripPlacement="Left">
<TabItem Header="Dashboard">
<Grid>
</Grid>
</TabItem>
<TabItem Header="Projects">
<Grid>
</Grid>
</TabItem>
<TabItem Header="Settings">
<Grid>
</Grid>
</TabItem>
<TabItem Header="Help & Info">
<Grid>
</Grid>
</TabItem>
</TabControl>
</Grid>
However, I don't have the slightest clue how to get the tabs the way I'd like them to be. I tried a lot with Blend to get the Tabs look the image above, but I don't get it. The triangle would be a nice to have, but the highlighting should be adapted.
Any advice?
Whenever you are having trouble with trying to make WPF UI elements look exactly the way you want, you should go find the default <style> XAML from microsoft and try modifying that directly in your project until you get the desired result.
In case that wasn't clear, you you need to do is follow the links below, copy the style from the pages and put them into the Resources section of your window (or App.xaml, its really up to you). Then fiddle with them until you get it to look the way you want.
The two styles you'll need to play with are TabControl and TabItem
I'd think to a MVVM approach, instead.
Before all, shape the model of the data, as well as the business layer (commands, functions, etc.).
Then, you can "wear" your model (by leveraging a ViewModel) with a ListBox, for the left selector, and a simple ContentControl for the main part.
The selected item of the ListBox should be fed into the content of the body, and a DataTemplateSelector (for instance) will choose the proper visual fragment.
It's just a suggestion. Personally, I've found a bit tricky the TabControl and I seldom use it.
Cheers
An old trick is to have 2 different sets of images - one for clicked and one for passive (maybe one for mouseover) but clicked image will have the triangle in it.
This uses static images for buttons, which is very easy to use, but hard to modify on the fly.
I'm making application in .NET C#.
It is not my choice but it has to be "multi-tab" application.
I have one window with tab control with many tabs.
There are many controls on every tab. Now all my event handlers and stuff is in main window file.
How to manage this program.
Is there any way to keep content of every tab in separate file (maybe class)?
Can use a frame and reference a page or user control
<TabControl>
<TabItem Header="Tab1 Page">
<Frame Source="TabPage.xaml" NavigationUIVisibility="Hidden" />
</TabItem>
<TabItem Header="Tab2 User Control">
<Frame Source="UserControl1Tab.xaml" />
</TabItem>
</TabControl>
A User Control is probably cleaner but I use Page out of habit.
They both have code behind for event handlers.
If you need to pass data then can do it in the ctor (but then you cannot assign the Source in XAML).
