I have a Combobox whose ItemsSource is an ObservableCollection of int values.
My combobox itemtemplate consists on an image and a textblock which content is given by 2 converters.
How can I set this 2 bindings? The following code does not compile:
<ComboBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Image Source="{Binding, Converter={StaticResource IntToImageConverter}}" Stretch="None" />
<TextBlock Text="{Binding, Converter={StaticResource IntToStringConverter}}" />
</StackPanel>
</DataTemplate>
</ComboBox.ItemTemplate>
You need to remove the , so:
<ComboBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Image Source="{Binding Converter={StaticResource IntToImageConverter}}" Stretch="None" />
<TextBlock Text="{Binding Converter={StaticResource IntToStringConverter}}" />
</StackPanel>
</DataTemplate>
</ComboBox.ItemTemplate>

I want to show just tree dataypes in my list view.(GeometryNode, ToolNode and StockNode). But my item source has 5 dataypes. How can I filter this datatypes?
My list view seems like that. And I want to remove or hide the items which are in top of the list view.
listview
<ListView.Resources>
<DataTemplate DataType="{x:Type treeview:MachineGeometryNodeViewItem}">
<StackPanel Orientation="Horizontal">
<Image Source="{Binding IconUri, Mode=OneWay}" Margin="0,0,5,0" Height="20" Width="20" />
<TextBlock Text="{Binding Name}"/>
</StackPanel>
</DataTemplate>
<DataTemplate DataType="{x:Type treeview:MachineToolNodeViewItem}">
<StackPanel Orientation="Horizontal">
<Image Source="{Binding IconUri, Mode=OneWay}" Margin="0,0,5,0" Height="20" Width="20" />
<TextBlock Text="{Binding Name}"/>
</StackPanel>
</DataTemplate>
<DataTemplate DataType="{x:Type treeview:MachineStockNodeViewItem}">
<StackPanel Orientation="Horizontal">
<Image Source="{Binding IconUri, Mode=OneWay}" Margin="0,0,5,0" Height="20" Width="20" />
<TextBlock Text="{Binding Name}"/>
</StackPanel>
</DataTemplate>
</ListView.Resources>
So i have ComboBox binding with my Person object list and i want to show all my object properties over my Combobox ToolTip.
Currently this is what i try:
<ComboBox
materialDesign:HintAssist.Hint="Network inteface"
materialDesign:HintAssist.IsFloating="True"
ItemsSource="{Binding Persons}"
Style="{StaticResource MaterialDesignFloatingHintComboBox}">
<ComboBox.ToolTip>
<ToolTip>
<StackPanel Orientation="Vertical">
<TextBlock Text="{Binding Path=Description}"/>
<TextBlock Text="{Binding Path=Name}"/>
<TextBlock Text="{Binding Path=Id}"/>
</StackPanel>
</ToolTip>
</ComboBox.ToolTip>
</ComboBox>
And all i can see this is empty little line of ToolTip
As I understand your issue. You have some confusion. You want to show all information in tooltip of invidual item i.e. comboboxItem, instead of comboBox. In your posted code, you are trying to get information in tooltip of combobox.
For combobox item, Please go through following code
<ComboBox ItemsSource="{Binding Persons}" SelectedValuePath="Id">
<ComboBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Name}">
<TextBlock.ToolTip>
<ToolTip>
<StackPanel Orientation="Vertical">
<TextBlock Text="{Binding Id}"/>
<TextBlock Text="{Binding Name}"/>
<TextBlock Text="{Binding Description}"/>
</StackPanel>
</ToolTip>
</TextBlock.ToolTip>
</TextBlock>
</DataTemplate>
</ComboBox.ItemTemplate>
<ComboBox.ItemContainerStyle>
<Style TargetType="{x:Type ComboBoxItem}">
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
</Style>
</ComboBox.ItemContainerStyle>
</ComboBox>
and here is result for reference
I have a TreeView and want to get the selected item from it.
The Treeview itself is populated not manually, but from data in the code. Since it is populated this way, I'm not sure how to get information out of it.
Here is the XAML:
<TreeView Name="trvFamilies" HorizontalAlignment="Left" Margin="10,10,3,3" Width="340">
<TreeView.Resources>
<HierarchicalDataTemplate DataType="{x:Type self:Scene}" ItemsSource="{Binding Characters}">
<StackPanel Orientation="Horizontal">
<StackPanel.ContextMenu>
<ContextMenu>
<MenuItem Header="New" Click="MenuItem_Click"></MenuItem>
<MenuItem Header="Remove" Click="MenuItem_Click_1"></MenuItem>
</ContextMenu>
</StackPanel.ContextMenu>
<Image Source="{StaticResource ImageSceneRegular}" Margin="0,0,5,0" Width="64" Height="64"/>
<TextBlock Text="{Binding Name}" />
<TextBlock Text=" [" Foreground="Blue" />
<TextBlock Text="{Binding Characters.Count}" Foreground="Blue" />
<TextBlock Text="]" Foreground="Blue" />
</StackPanel>
</HierarchicalDataTemplate>
<DataTemplate DataType="{x:Type self:Character}">
<Border BorderThickness="1" Background="AliceBlue" CornerRadius="8,8,3,3">
<StackPanel Orientation="Horizontal" Margin="4" Background="White">
<Image Source="{Binding Img}" Margin="0,0,5,0" Width="64" Height="64" />
<TextBlock Text="{Binding Name}" />
<TextBlock Text=" (" Foreground="Green" />
<TextBlock Text="{Binding Age}" Foreground="Green" />
<TextBlock Text=" years)" Foreground="Green" />
</StackPanel>
</Border>
</DataTemplate>
</TreeView.Resources>
</TreeView>
It is populated by data from an ObservableCollection which is populated within the code and then assigned to the ItemSource of the treeview (and it works fine).
So let's say I had a TextBlock which sat outside the TreeView and wanted to populate it with information from the selected Character (that's the type which populates the drop down part of the TreeView), I don't know how to do that, be it using XAML only or code behind.
Any help on how to do this would be very much appreciated.
I have created a WPF app.In that I have a Datatemplate as follows
<DataTemplate x:Key="ItemTemplate">
<StackPanel>
<TextBlock Text="item"/>
<TextBlock Text="{Binding Number}"/>
</StackPanel>
</DataTemplate>
I have an ItemsControl like this
<ItemsControl ItemsSource="{Binding Items}"
Grid.Column="1"
Grid.Row="3"
ItemTemplate="{StaticResource ItemTemplateWithButton}" />
where I need a itemtemplate like this
<DataTemplate x:Key="ItemTemplateWithButton">
<StackPanel>
<StackPanel>
<TextBlock Text="item"/>
<TextBlock Text="{Binding Number}"/>
</StackPanel>
<StackPanel>
<Button>
<StackPanel>
<TextBlock Text="item"/>
<TextBlock Text="{Binding Number}"/>
</StackPanel>
</Button>
</StackPanel>
</StackPanel>
</DataTemplate>
Is there any possibility of reusing the datatemplate in the new itemscontrol?
You can use ContentControl too
<DataTemplate x:Key="ItemTemplate">
<StackPanel>
<TextBlock Text="item"/>
<TextBlock Text="{Binding Number}"/>
</StackPanel>
</DataTemplate>
<DataTemplate x:Key="ItemTemplateWithButton">
<StackPanel>
<ContentControl ContentTemplate="{StaticResource ItemTemplate}" />
<Button>
<ContentControl ContentTemplate="{StaticResource ItemTemplate}" />
</Button>
</StackPanel>
</DataTemplate>
What I understand by reading this answer and what Liero mentioned in the comments is it's possible to reuse a DataTemplate by using either ContentPresenter or ContentControl. However:
ContentPresenter is more lightweight.
ContentPresenter is designed to be used inside control templates.
ContnetPresenter is designed to be used as-is while ContentControl is designed to be extended (inherited from).
As a result, here is a solution based on what you asked:
<DataTemplate x:Key="ItemTemplate">
<StackPanel>
<TextBlock Text="item"/>
<TextBlock Text="{Binding Number}"/>
</StackPanel>
</DataTemplate>
<DataTemplate x:Key="ItemTemplateWithButton">
<StackPanel>
<ContentPresenter ContentTemplate="{StaticResource ItemTemplate}"/>
<StackPanel>
<Button Content="{Binding}" ContentTemplate="{StaticResource ItemTemplate}" />
</StackPanel>
</StackPanel>
</DataTemplate>
You could create a UserControl to hold the xaml you want to reuse:
<UserControl x:Class="StackOverflow.SharedControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Grid>
<StackPanel>
<TextBlock Text="item">
</TextBlock>
<TextBlock Text="{Binding Number}"></TextBlock>
</StackPanel>
</Grid>
</UserControl>
Then use this UserControl in both templates.
<DataTemplate x:Key="ItemTemplate">
<controls:SharedControl/>
</DataTemplate>
<DataTemplate x:Key="ItemTemplateWithButton">
<StackPanel>
<controls:SharedControl/>
<StackPanel>
<Button>
<StackPanel>
<TextBlock Text="item">
</TextBlock>
<TextBlock Text="{Binding Number}"></TextBlock>
</StackPanel>
</Button>
</StackPanel>
</StackPanel>
</DataTemplate>
<ListBox Height="498" Margin="2,0,0,0" Name="listBox1" Width="879" ItemsSource="{Binding}" >
<ListBoxItem >
<StackPanel Width="418" Orientation="Horizontal">
<TextBlock Name="MedicineName" Text="Alamoxy"
FontWeight="Bold" FontSize="18"
Margin="5" Width="205" >
</TextBlock>
<TextBlock Name="ListBoxLetter" Text="Amoksilin"
FontSize="18" Margin="0" Width="255" Height="23">
</TextBlock>
</StackPanel>
</ListBoxItem>
</ListBox>
I want to bind data to the listbox.
Textblock will show seprate fields. How i can do it?
please Help me about this/
Use an ItemTemplate to make it look something like this.
<ListBox Width="400" Margin="10" ItemsSource="{Binding myItems}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding Path=MedicineName}" />
<TextBlock Text="{Binding Path=ListBoxLetter}"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
