i am trying to do some people administration application and i would like to use own component. I have a listBox with actions and i would like to show people who are in list in selected action. There is no problem for me to show just their names in another list, but i would like to have a pane where would be a card (my component) for every person asociated with that action. That card should look like
<WrapPanel HorizontalAlignment="Left" Height="296" Margin="668,59,0,0" VerticalAlignment="Top" Width="230">
<Image x:Name="image" Height="124" Width="226"/>
<TextBlock x:Name="textBlock_Copy5" TextWrapping="Wrap" Text="Name: " FontSize="18"/>
<TextBox x:Name="textBox_Copy2" Height="25" TextWrapping="Wrap" Width="151"/>
<TextBlock x:Name="textBlock_Copy6" TextWrapping="Wrap" Text="Surname: " FontSize="18"/>
<TextBox x:Name="textBox_Copy3" Height="25" TextWrapping="Wrap" Width="145"/>
<TextBlock x:Name="textBlock_Copy7" TextWrapping="Wrap" Text="Birthday: " FontSize="18"/>
<DatePicker Width="136" DisplayDate="2016-06-27" DisplayDateStart="1950-01-01" FirstDayOfWeek="Monday" SelectedDate="{Binding Selected.DatumOdjezdu}"/>
</WrapPanel>
So there are two problems for me.
How to create own component.
How to create a pane(it can be scrollable), where would be as many those cards as needed.
Thanks for any hint.
WPF offers more than one way to achieve your goal.
It depends on your Application, what fits your needs the most.
You can reach this by
DataTemplates
UserControl
CustomControl
Here some more Info about the Differences of UserControl and CustomControl
Depending on your posted Code, i'd suggest a DataTemplate in your case.
I was trying to use the settings flyout in phone 8.1 runtime to produce a settings screen for an app. However the compiler is throwing an error and I dont no why. This would have worked fine in phone 8.0 but not 8.1 runtime it seems.

My base class is just the same as other pages
Note 2
public partial class Settings : Page
I changed above to settings and it compiled but the flyount did not work or popup so it didnt any idea as to why it didnt.
Note 2
To Avoid confusion I dont want a base page of page I wanted to be able to use the settingsflyout that was part of 8.0 apparently microsoft have dicthced this though for 8.1 UAP
The exception tells you everything you need to know.
Look at your xaml. Here's the top two lines of your file:
<SettingsFlyout
x:Class="popcornpk.Settings"
This says that you're declaring a new class called popcornpk.Settings (btw, namespaces should be PascalCased) that extends the base class SettingsFlyout.
When you add a new xaml file to your application, it actually creates three files--the .xaml file, a .xaml.cs file that you edit, and a mysterious ephemeral .g.i.cs file that holds designer-generated code (e.g., the implementation of InitializeComponent()).
The .xaml.cs and .g.i.cs files are partial class files, and are combined by the compiler. Note what the exception message says--
Partial declarations of 'Settings' must not specify different base classes
What are these different base classes?
Well, from the xaml, we can see the first one--SettingsFlyout.
From your snippet,
public partial class Settings : Page
We see the other base class--Page.
Not sure how you screwed that up, but the simple fix is to remove the base class declaration from your .xaml.cs file:
public partial class Settings
{
// snip
Apart from what Will has said about partial classes, which will surely solve the error, you probably won't be able to use SettingsFlyout on Phone - following the remarks:
Caution SettingsFlyout is supported only for use with the SettingsPane in Windows 8. While the SettingsFlyout type is visible in Windows Phone projects, SettingsPane is not present on Windows Phone, so use of SettingsFlyout is not supported.
Porting an iOS app and I may be abusing the hub control; but I have a very simple app where I'd like a form to be in a hub section. However it seems like it must be wrapped in a DataTemplate and once it is the form's TextBox controls do not show up in the code behind C# file?
<HubSection x:Uid="HubSection1" Header="SETTINGS"
DataContext="{Binding Groups[2]}" HeaderTemplate="{ThemeResource HubSectionHeaderTemplate}">
<DataTemplate>
<StackPanel VerticalAlignment="Top" Margin="0,0,20,0">
<TextBlock Text="api base uri" FontSize="21" TextWrapping="NoWrap"/>
<TextBox Name="apiBaseUriTextBox" Margin="0,0,0,10" TextWrapping="Wrap" PlaceholderText="api base uri" VerticalAlignment="Stretch"/>
<TextBlock Text="api key" FontSize="21" TextWrapping="NoWrap" Margin="0,0,0,10"/>
<TextBox Name="apiKeyTextBox" Margin="0,0,0,10" TextWrapping="Wrap" PlaceholderText="api key" VerticalAlignment="Stretch"/>
<TextBlock Text="api secret" FontSize="21" TextWrapping="NoWrap"/>
<TextBox Name="apiSecretTextBox" Margin="0,0,0,10" TextWrapping="Wrap" PlaceholderText="api secret" VerticalAlignment="Stretch"/>
<Button Click="SettingsSaveClickHandler"
Content="Save" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="0,20,0,0"/>
</StackPanel>
</DataTemplate>
</HubSection>
If you want to put the form directly in the HubSection's DataTemplate then the best way to access the values is by data binding the TextBoxes to properties in your DataContext. The other option would be to crawl the visual tree by calling the VisualTreeHelper from your button's SettingsSaveClickHandler
Another option would be to create your form as a UserControl and then host the completed form in the HubSection's DataTemplate. Again, you can bind it to the DataContext to connect to the underlying data.
I have a bunch (currently) HyperlinkButtons on my main web page. I want to have 2 versions for the image of each button: selected and unselected. This way when the users enters a page the corresponding button will change to the "selected" image.
Here is an image of what I want to accomplish:
This seems to me like something trivial, but so far I have been running into a stone wall.
I would prefer to do everything from the XAML (but I will be grateful for any solution).
Here is a little of my XAML:
<ScrollViewer x:Name="NavScrollViewer" Margin="-5,12,5,-12" ScrollViewer.VerticalScrollBarVisibility="Visible" IsEnabled="True"
Style="{StaticResource ContentViewerStyle}">
<StackPanel x:Name="ToolboxPanel" Orientation="Vertical" d:LayoutOverrides="Width" Height="Auto">
<HyperlinkButton x:Name="DashboardButton"
Content="Assets/icon_dashboard.png"
Style="{StaticResource ToolStyle}"
TargetName="ContentFrame"
NavigateUri="/Dashboard"
Height="50"
/>
<TextBlock Text="Dashboard" HorizontalAlignment="Center" Height="20" Style="{StaticResource ComponentNameStyle}"/>
<HyperlinkButton x:Name="ConfigurationButton"
Content="Assets/icon_dashboard.png"
Style="{StaticResource ToolStyle}"
TargetName="ContentFrame"
NavigateUri="/CRSConfiguration"
Height="50"
/>
<TextBlock Text="Configuration" HorizontalAlignment="Center" Height="20" Style="{StaticResource ComponentNameStyle}"/>
<HyperlinkButton x:Name="ScanEnginestionButton"
Content="Assets/icon_dashboard.png"
Style="{StaticResource ToolStyle}"
TargetName="ContentFrame"
NavigateUri="/ScanEngines"
Height="50"
/>...
You need to have a toggle button and set its IsChecked property to toggle among its visual states. You may go through this post Using Toggle Button
Scenario:
Currently I have this XAML code:
<Button Content="_Cancel" IsCancel="True" Command="{Binding Path=CancelCommand}" Margin="5">
<Button.ContentTemplate>
<DataTemplate>
<TextBlock Margin="10,0,10,0" />
</DataTemplate>
</Button.ContentTemplate>
</Button>
Obviously the accesskey (the 'c' key: _Cancel) doesn't work in combination with the TextBlock. I actually think the TextBlock should be a ContentPresenter (below), but this crashes my Visual Studio 2010 instance every time.
<ContentPresenter Margin="10,0,10,0" RecognizesAccessKey="True" />
Question:
What's the best solution to use accesskeys on a WPF Button with a ContentTemplate?
Thanks in advance!
Instead of TextBlock use AccessText thus:
<Button Content="_Cancel" IsCancel="True" Command="{Binding Path=CancelCommand}" Margin="5">
<Button.ContentTemplate>
<DataTemplate>
<AccessText Margin="10,0,10,0" Text="{Binding}"/>
</DataTemplate>
</Button.ContentTemplate>
</Button>
PS. ContentPresenter should be used inside a ControlTemplate to display content according to a DataTemplate. If you use it within a DataTemplate it causes infinite recursion as the DataTemplate is invoked over and over again.
