Currently I am implementing an app using HamburgerControlMenu from Mahapps.Metro toolkit.
I need to focus a specific HambugerMenu Item by code, after an event.
This is the WPF code:
<Grid.Resources>
<DataTemplate x:Name="aa" x:Key="MenuItemTemplate" DataType="{x:Type viewModels:MenuItem}">
<Grid x:Name="gridMain" Height="48">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="48" />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<ContentControl Grid.Column="0"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Foreground="White"
Focusable="False"
Content="{Binding Icon}"/>
<TextBlock x:Name="txtBlockMenu"
Grid.Column="1"
VerticalAlignment="Center"
FontSize="16"
Foreground="White"
Text="{Binding Text}" />
</Grid>
</DataTemplate>
</Grid.Resources>
<controls:HamburgerMenu x:Name="HamburgerMenuControl"
Foreground="White"
PaneBackground="#FF444444"
IsPaneOpen="False"
ItemsSource="{Binding Menu}"
OptionsItemsSource="{Binding OptionsMenu}"
ItemClick="HamburgerMenuControl_OnItemClick"
OptionsItemClick="HamburgerMenuControl_OnItemClick"
ItemTemplate="{StaticResource MenuItemTemplate}"
OptionsItemTemplate="{StaticResource MenuItemTemplate}"/>
Little help would be great.
Set the SelectedIndex or SelectedItem property. The following will for example select the second item at index 1:
HamburgerMenuControl.IsPaneOpen = true;
HamburgerMenuControl.SelectedIndex = 1;
you can set it using :
this.*yourHamburgerControlName*.SelectedIndex = *InsertHere the position of your HamburgerMenuItem in the ItemSource*;

Here is my code:

</Grid.ColumnDefinitions>
<TextBlock Visibility="Visible" Name="quantity" Grid.Column="0" Foreground="{DynamicResource GrayTextDonaTotaBrush}" HorizontalAlignment="Center" VerticalAlignment="Center" TextWrapping="Wrap" Text="{Binding amount}"/>
<TextBlock Margin="10,0,0,0" Grid.Column="1" Foreground="{DynamicResource GrayTextDonaTotaBrush}" HorizontalAlignment="Left" VerticalAlignment="Center" TextWrapping="Wrap" Text="{Binding ing.name}"/>

</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
I add data to the ListView viewTicket, but depending of a property I would like to change the ItemSource Binding of the ListView viewTicketIngs. In other words, is there anyway that I can use an if expression on the binding? Something like ItemsSource="{Binding IF(mode == 0) {ingredients} else {plates}}"
Change the Binding by a DataTrigger in a Style:
<ListView ...>
<ListView.Style>
<Style TargetType="ListView">
<Setter Property="ItemsSource" Value="{Binding plates}"/>
<Style.Triggers>
<DataTrigger Binding="{Binding mode}" Value="0">
<Setter Property="ItemsSource" Value="{Binding ingredients}"/>
</DataTrigger>
</Style.Triggers>
</Style>
</ListView.Style>
</ListView>
As I understand it, you sometimes dispaly plates, sometimes ingredients. Now there are triggers conditional display. WPF actually has a pretty wide support.
However what might be better is to have 2 different ViewModel classes and two (how I call them) "type targetting data tempaltes". Say you have these clases:
abstract class ViewModelItem { }
class Plate : ViewModelItem { }
class IngredientsList : ViewModelItem { }
The propety you exposie this in, would be set to ViewModelItem. In realtiy you would assign either a Plate or IngredientsList Instance.
Now you define two DataTemplates. A interesting thing about WPF is that if you do not specify a explicit Template, the Code will go out of it's way to try to find one. And it will do the matching via the DataType property of the Template (TargetType for Styles and similar). It works similar to what CSS does, with somebodies code going out of it's way to find a template to apply.
I need to binding objects of the lists below in a ItemsControl binded in a ScrollViewer in wpf .
I Provand assigning a path but I still can not binding, maybe I'm wrong ? In the subject of the first level the bind is successful , but when I go down in the lists below of the same object bind will not work.
Xaml Scrollviewer:
<surface:SurfaceScrollViewer Grid.Row="2" VerticalScrollBarVisibility="Hidden" Background="#fff" PanningMode="VerticalOnly">
<ItemsControl x:Name="scrollViewerFolderItemsSource" ItemsSource="{Binding Path=companies}">
<ItemsControl.ItemTemplate>

</Grid.RowDefinitions>
<Grid Grid.Row="0" Background="#fff"></Grid>
<Image Grid.Row="0" Grid.Column="0" Width="32" VerticalAlignment="Center" HorizontalAlignment="Center" Source="{Binding ImageFolder}"></Image>

</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</surface:SurfaceScrollViewer>
CodeBehind view list binded:
My target is binding Text="{Binding companies.Attachment.Name}"
If i print Text="{Binding Attachment}" my result print on deploy is "(Collection)", why print Attachment.Name ?
Attachments is a Collection, to visualize a collection you should use a ListBox and use this binding ItemsSource="{Binding companies.Attachment}", you also need to define the ItemTemplate for the ListBox.
With the ListBox you are able to visualize all the element, but if you want to show just the first attachment name you can use this binding Text="{Binding companies.Attachment[0].Name}"
or another solution could be to create a new property called AttachmentToShow of type Attachment and use this binding
Text="{Binding AttachmentToShow.Name}"
with this solution updating AttachmentToShow will result on an UI update.
Each list item must be
TextBlock 1 fill first row with 100% width;
TextBlock 2,3,4 must fill 33% each on separate row;
Why TextBlock 2,3,4 not strech?
<ListView.ItemTemplate><DataTemplate><StackPanel>
<TextBlock Text="{Binding Name}" />
<Grid HorizontalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"></ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<TextBlock TextAlignment="Right" Grid.Row="0" Grid.Column="0"
HorizontalAlignment="Stretch" VerticalAlignment="Center"
Text="{Binding Rest}" FontSize="28"/>
<TextBlock TextAlignment="Right" Grid.Row="0" Grid.Column="1"
HorizontalAlignment="Stretch" VerticalAlignment="Center"
Text="{Binding Currency.Name}" FontSize="25"/>
<TextBlock TextAlignment="Right" Grid.Row="0" Grid.Column="2"
HorizontalAlignment="Stretch" VerticalAlignment="Center"
Text="{Binding FullRest}" FontSize="22"/>
</Grid>
</StackPanel></DataTemplate></ListView.ItemTemplate>
P.S.
How i can add 1...x rows in list view in design time?
Use ListView.ItemContainerStyle
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
</Style>
</ListView.ItemContainerStyle>
This code (with normal values, because I don't have the underlying data structure) works fine for me.
Different rows can have different widths however. That can be fixed by setting the Width of the StackPanel to the ActualWidth - margins of the listview.
You can find some info about how to add mock data, for usage in the designer, here: How to get mock data into listview during design time and real data at run time in WPF
I used a ListBox to bind my data in similar way.
You will need to give stackpanel specific width
And you will have to set textwrapping property to 'no wrap'
<ListBox x:Name="listbox" >
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Width="480">
<TextBlock Text="{Binding main}" />
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<TextBlock TextWrapping="NoWrap" Text="{Binding one}"/>
<TextBlock TextWrapping="NoWrap" Text="{Binding two}" Grid.Column="1"/>
<TextBlock TextWrapping="NoWrap" Text="{Binding thr}" Grid.Column="2"/>
</Grid>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
This Works perfectly for me!
I'm updating my project from .NET Framework 3.5 to .NET Framework 4.5.1. Everything works, except my databinding to a ComboBox. The ComboBox is part of a Itemscontrol. The XAML code:
<ItemsControl x:Name="AfmetingenLijst" BorderBrush="{DynamicResource {x:Static SystemColors.ActiveBorderBrushKey}}" BorderThickness="0" VerticalContentAlignment="Bottom" >
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid Margin="5,5,5,5">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="2*" />
<ColumnDefinition Width="2*" />
<ColumnDefinition Width="2*" />
<ColumnDefinition Width="2*" />
<ColumnDefinition Width="2*" />
<ColumnDefinition Width="1*" />
</Grid.ColumnDefinitions>
<TextBox Grid.Column="0" Text="{Binding Lengte}" Tag="{Binding LID}" Margin="5,5,5,5" TextChanged="UpdateList"/>
<TextBox Grid.Column="1" Text="{Binding Breedte}" Tag="{Binding BID}" Margin="5,5,5,5" TextChanged="UpdateList"/>
<TextBox Grid.Column="2" Text="{Binding Hoogte}" Tag="{Binding HID}" Margin="5,5,5,5" TextChanged="UpdateList"/>
<TextBox Grid.Column="3" Text="{Binding Naam}" Margin="5,5,5,5" />
<ComboBox Grid.Column="4" ItemsSource="{Binding Path=items}" SelectedIndex="{Binding geselecteerdProduct}" SelectedValuePath="Code" DisplayMemberPath = "Naam" SelectionChanged="UpdateList" Height="25" HorizontalAlignment="Stretch" VerticalAlignment="Center"></ComboBox>
<Button Tag="{Binding ID}" Grid.Column="5" Margin="5,5,5,5" Content="{Binding Title}" Click="Afmeting_handler" />
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
In C# a list is filled with the databinding values:
afm = new List<Afmeting>();
if (afm.Count == 0)
{
afm.Add(new Afmeting() { ID = "+", LID = "L+", BID = "B+", HID = "H+", Title = "+", items = items });
afm[afm.Count - 1].geselecteerdProduct = 0;
afmetingen_counter++;
}
AfmetingenLijst.ItemsSource = afm;
The items in the ComboBox exists, I can select them by mouse. But by default SelectedIndex = -1. But in the list "geselecteerdProduct" (the databinding to SelectedIndex) is set to 0.
In .NET 3.5 it is working perfect, but in 4.x SelectedIndex and the value in "afm" is automatically set to -1.
Items is not empty, there are +- 5 items in the list.
Can someone help me?
I think this is a bug for WPF.
When ComboBox is nested in ItemsControl, and set SelectedIndex and SelectedValuePath at the same time, ComboBox's OnSelectionChanged will be fired tiwce at initialize, but SelectionChanged only once.
WPF ComboBox SelectedIndex debug:
To solve the problem is simple, just remove SelectedValuePath from the ComboBox.
XAML:
<ItemsControl x:Name="AfmetingenLijst" BorderBrush="{DynamicResource {x:Static SystemColors.ActiveBorderBrushKey}}" BorderThickness="0" VerticalContentAlignment="Bottom" >
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid Margin="5,5,5,5">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="2*" />
<ColumnDefinition Width="2*" />
<ColumnDefinition Width="2*" />
<ColumnDefinition Width="2*" />
<ColumnDefinition Width="2*" />
<ColumnDefinition Width="1*" />
</Grid.ColumnDefinitions>
<TextBox Grid.Column="0" Text="{Binding Lengte}" Tag="{Binding LID}" Margin="5,5,5,5" TextChanged="UpdateList"/>
<TextBox Grid.Column="1" Text="{Binding Breedte}" Tag="{Binding BID}" Margin="5,5,5,5" TextChanged="UpdateList"/>
<TextBox Grid.Column="2" Text="{Binding Hoogte}" Tag="{Binding HID}" Margin="5,5,5,5" TextChanged="UpdateList"/>
<TextBox Grid.Column="3" Text="{Binding Naam}" Margin="5,5,5,5" />
<ComboBox Grid.Column="4"
ItemsSource="{Binding Path=items}"
SelectedIndex="{Binding geselecteerdProduct}"
DisplayMemberPath = "Naam"
SelectionChanged="UpdateList"

I read many tutorials from MSDN about WPF styling and datatemplating and contenttemplating but no success.
I need to make same TabItems in my TabControl and I made manually TabItem which i want to use as host for Style and ContentTemplate for other TabItems in TabControl
<TabItem Header="1.semestar">
<Grid x:Name="GridSemestra">
<Grid.DataContext>
<ViewModel:PredmetVM/>
</Grid.DataContext>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition MinWidth="100"/>
<ColumnDefinition MinWidth="30"/>
</Grid.ColumnDefinitions>
<Grid.Children>
<ListBox x:Name="PredmetiLW" Grid.Row="0" BorderThickness="0" Grid.Column="0" ItemsSource="{Binding Predmeti}" HorizontalAlignment="Center" VerticalAlignment="Center" >
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Naziv}" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<ListBox x:Name="RadioLW" Grid.Row="0" Grid.Column="1" BorderThickness="0" ItemsSource="{Binding Predmeti}" HorizontalAlignment="Center" VerticalAlignment="Center" >
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Ocjena}"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<Label Content="Prosjek Semestra :" HorizontalAlignment="Right" VerticalAlignment="Center" Grid.Row="1" Grid.Column="0" />
<Label x:Name="_prosjekSemestra" Grid.Row="1" Grid.Column="1" ContentStringFormat="F2" Content="{Binding _prosjek, Mode=OneWay}" HorizontalAlignment="Center" VerticalAlignment="Center" />
<Label Content="Ostvareni ECTS-ovi :" HorizontalAlignment="right" VerticalAlignment="Center" Grid.Row="2" Grid.Column="0" />
<Label x:Name="_ectsSemestra" Grid.Row="2" Grid.Column="1" Content="{Binding _ectsovi, Mode=OneWay}" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Grid.Children>
</Grid>
</TabItem>
This is how you define a style for any TabItem. In the example I created a white border and a black background for the Header content of the TabItem:
<Style TargetType="{x:Type TabItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Border BorderBrush="White" BorderThickness="5" Margin="2">
<Grid Width="100" Height="100" Background="Black">
<ContentPresenter x:Name="ContentSite"
VerticalAlignment="Center"
HorizontalAlignment="Center"
ContentSource="Header"
RecognizesAccessKey="True"/>
</Grid>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
If you want your items to render with same template set the ItemTemplate for your TabControl like below:
<TabControl ItemsSource="{Binding MyTabItems}">
<TabControl.ItemTemplate>
<DataTemplate>
<Grid x:Name="GridSemestra">
<Grid.DataContext>
<ViewModel:PredmetVM/>
</Grid.DataContext>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition MinWidth="100"/>
<ColumnDefinition MinWidth="30"/>
</Grid.ColumnDefinitions>
<Grid.Children>
<ListBox x:Name="PredmetiLW" Grid.Row="0" BorderThickness="0" Grid.Column="0" ItemsSource="{Binding Predmeti}" HorizontalAlignment="Center" VerticalAlignment="Center" >
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Naziv}" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<ListBox x:Name="RadioLW" Grid.Row="0" Grid.Column="1" BorderThickness="0" ItemsSource="{Binding Predmeti}" HorizontalAlignment="Center" VerticalAlignment="Center" >
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Ocjena}"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<Label Content="Prosjek Semestra :" HorizontalAlignment="Right" VerticalAlignment="Center" Grid.Row="1" Grid.Column="0" />
<Label x:Name="_prosjekSemestra" Grid.Row="1" Grid.Column="1" ContentStringFormat="F2" Content="{Binding _prosjek, Mode=OneWay}" HorizontalAlignment="Center" VerticalAlignment="Center" />
<Label Content="Ostvareni ECTS-ovi :" HorizontalAlignment="right" VerticalAlignment="Center" Grid.Row="2" Grid.Column="0" />
<Label x:Name="_ectsSemestra" Grid.Row="2" Grid.Column="1" Content="{Binding _ectsovi, Mode=OneWay}" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Grid.Children>
</Grid>
</DataTemplate>
</TabControl.ItemTemplate>
</TabControl>
Doing this, for all the items in property MyTabItems, TabItems will be generated
