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'm about to design a DropDown in WPF using XAML. If my text gets longer than the Width my DropDown element of the ComboBox is larger than the TextBox (as shown by the red arrow). Texts beeing to long are handled by an elllipsis (...).
Any ideas how to correct this?
This is my current XAML code:
<ItemsControl x:Name="ItemsControl"
ItemsSource="{Binding FilterUiModels}">
<ItemsControl.ItemTemplate>
<DataTemplate x:Name="UiModelTemplate">
<ComboBox x:Name="FilterComboBox"
ItemsSource="{Binding AvailableItems}"
SelectedItem="{Binding FilterItem}"
ScrollViewer.CanContentScroll="False"
Width="200">
<ComboBox.ItemTemplate>
<DataTemplate>
<TextBlock Width="{Binding ActualWidth, ElementName=FilterComboBox}"
Text="{Binding}"
TextTrimming="CharacterEllipsis">
</TextBlock>
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
Bind the Width of the Popup to the Width of the ComboBox and set the ScrollViewer.HorizontalScrollBarVisibility attached property to false to hide any horizontal scrollbar:
<ComboBox x:Name="FilterComboBox"
ItemsSource="{StaticResource localTimeList}"
SelectedItem="{Binding FilterItem}"
ScrollViewer.CanContentScroll="False"
ScrollViewer.HorizontalScrollBarVisibility="Disabled"
Width="200">
<ComboBox.Resources>
<Style TargetType="Popup">
<Setter Property="Width" Value="{Binding ActualWidth, ElementName=FilterComboBox}"/>
</Style>
</ComboBox.Resources>
<ComboBox.ItemTemplate>
<DataTemplate>
<TextBlock Width="{Binding ActualWidth, ElementName=FilterComboBox}"
Text="{Binding}"
TextTrimming="CharacterEllipsis">
</TextBlock>
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
I'm trying to add a tooltip for each username(CreatedBy) in my combobox in case the user name is too long for the width of the combobox.
I know this question has been asked a million times, I've tried using Style.Triggers method and I have also tried
ToolTip="{Binding Path=SelectedCreatedBy.ToolTip, RelativeSource={RelativeSource Self}}
<ComboBox ItemsSource="{Binding CreatedBys.DefaultView}" SelectedValue="{Binding SelectedCreatedBy,UpdateSourceTrigger=PropertyChanged}" SelectedValuePath="CreatedBy" DisplayMemberPath="CreatedBy" ToolTip="{Binding SelectedCreatedBy}"
Grid.Row="3" Grid.Column="12" Height="22" Width="85" FontSize="11" IsEditable="{Binding IsCreatedByEditable}" VerticalAlignment="Top" HorizontalAlignment="Left" >
Edit: I found the solution and I will post the code here
<ComboBox ItemsSource="{Binding CreatedBys.DefaultView}" SelectedValue="{Binding SelectedCreatedBy,UpdateSourceTrigger=PropertyChanged}" SelectedValuePath="CreatedBy" DisplayMemberPath="CreatedBy" ToolTip="{Binding SelectedCreatedBy}"
Grid.Row="3" Grid.Column="12" Height="22" Width="85" FontSize="11" IsEditable="{Binding IsCreatedByEditable}" VerticalAlignment="Top" HorizontalAlignment="Left" >
<ComboBox.ItemContainerStyle>
<Style>
<Setter Property="Control.ToolTip" Value="{Binding CreatedBy}" />
</Style>
</ComboBox.ItemContainerStyle>
</ComboBox>
If I understand correctly, you want a tool tip to appear for each of your combo box choices (not just the selected one). If that's the case, add the following code inside your ComboBox:
<ComboBox.ItemTemplate>
<DataTemplate>
<TextBlock
Text="{Binding CreatedBy}"
ToolTip="{Binding ToolTip}"
/>
</DataTemplate>
</ComboBox.ItemTemplate>
<ComboBox.ItemContainerStyle>
<Style TargetType="ComboBoxItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
</Style>
</ComboBox.ItemContainerStyle>
The ItemTemplate defines a TextBlock for each item with a ToolTip bound to the ToolTip property of your view model. The ItemContainerStyle stretches the ComboBoxItem so that the tool tip appears even if the mouse is not directly on the text but over the item.
I have the following code to allow users to select multiple items from a combobox. However when they click one item, it makes this the displayed text when combobox closes. Can I change the displayed text to something that isnt just the item selected. For example if the users select items A,B and D, I want the text part of the combobox to show "A, B, D"
<ComboBox ItemsSource="{Binding ListOfItems}">
<ComboBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<CheckBox IsChecked="{Binding IsChecked, Mode=TwoWay}" Width="20" />
<TextBlock Text="{Binding DisplayName}" Width="110" />
</StackPanel>
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
Thanks
You could use a ContentControl with a Style that changes the ContentTemplate property for the selected item. The following sample markup should give you the idea.
<ComboBox ItemsSource="{Binding ListOfItems}">
<ComboBox.ItemTemplate>
<DataTemplate>
<ContentControl Content="{Binding}">
<ContentControl.Style>
<Style TargetType="ContentControl">
<Setter Property="ContentTemplate">
<Setter.Value>
<!-- the template for the items in the dropdown list -->
<DataTemplate>
<StackPanel Orientation="Horizontal">
<CheckBox IsChecked="{Binding IsChecked, Mode=TwoWay}" Width="20" />
<TextBlock Text="{Binding DisplayName}" Width="110" />
</StackPanel>
</DataTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource AncestorType=ComboBoxItem}}" Value="{x:Null}">
<Setter Property="ContentTemplate">
<Setter.Value>
<!-- the template for the selected item-->
<DataTemplate>
<ItemsControl ItemsSource="{Binding ItemsSource, RelativeSource={RelativeSource AncestorType=ComboBox}}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding DisplayName}" Margin="0 0 5 0"/>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</DataTemplate>
</Setter.Value>
</Setter>
</DataTrigger>
</Style.Triggers>
</Style>
</ContentControl.Style>
</ContentControl>
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
Please refer to the following similar question for more information.
Can I use a different Template for the selected item in a WPF ComboBox than for the items in the dropdown part?
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 have a TreeView where each node has an icon and a descriptive text. But I do not want any node can be selected. Instead, I want that each node act as a button. It run a command when the user press it. But it may not look like a button or hyperlink
This is what I tried so far. The problem is that the text is blue and the text underlined. In addition, sometime the node is selected and therefore blue.
<TreeView.Resources>
<HierarchicalDataTemplate DataType="{x:Type vm:ListGroupViewModel}" ItemsSource="{Binding Children}">
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Text}" FontWeight="Bold" ></TextBlock>
</StackPanel>
</HierarchicalDataTemplate>
<DataTemplate DataType="{x:Type vm:ListNodeViewModel}">
<TextBlock>
<Hyperlink TextDecorations="{x:Null}" Command="{Binding ClickCommand, Mode=OneTime}">
<StackPanel Orientation="Horizontal">
<Image Margin="0,2,2,0" Source="{Binding Icon}" />
<TextBlock Text="{Binding Text}" />
</StackPanel>
</Hyperlink>
</TextBlock>
</DataTemplate>
</TreeView.Resources>
You should override hyperlink style:
<Style x:Key="HyperlinkStyle" TargetType="Hyperlink">
<Setter Property="Foreground"
Value="Black"/>
<Setter Property="TextDecorations"
Value="{x:Null}"/>
</Style>
<DataTemplate DataType="{x:Type vm:ListNodeViewModel}">
<TextBlock>
<Hyperlink Command="{Binding ClickCommand, Mode=OneTime}"
Style="{StaticResource HyperlinkStyle}">
<StackPanel Orientation="Horizontal">
<Image Margin="0,2,2,0" Source="{Binding Icon}" />
<TextBlock Text="{Binding Name}" />
</StackPanel>
</Hyperlink>
</TextBlock>
</DataTemplate>
To hide tree item selection you could override SystemColors.HighlightBrushKey, which tree view uses to highlight items:
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent"/>
