So i've looked around but have been unable to find an answer to this issue. I am trying to style a combobox that has DisplayMemberPath. As long as that field is set the fontsize that I set has no effect on the combobox. I've also tried applying template styles, but the results are the same for the font. The question/answer listed in question "ComboBox Style problems with DisplayMemberPath" doesn't address fontsize but appears to be more geared to resulting colors.
Here is the combobox:
<ComboBox
Grid.Row="0"
Height="36"
VerticalAlignment="Center"
ItemsSource="{Binding VideoDeviceFilters}"
SelectedValue="{Binding VideoDeviceFilter}"
DisplayMemberPath="Name"
Margin="0,11.857,1.333,11.856"
Grid.Column="1"
TextBlock.FontSize="18.333"/>
And here is the combobox without the displaymemberpath:
<ComboBox Grid.Row="1"
Height="35"
VerticalAlignment="Center"
Margin="0,12.857,1.333,11.856"
ItemsSource="{Binding InstalledPrinters}"
SelectedValue="{Binding Printer}"
Grid.Column="1"
TextBlock.FontSize="18.333"/>
Here is also the style declared in the view:
<UserControl.Resources>
<Style TargetType="{x:Type ComboBoxItem}">
<Setter Property="SnapsToDevicePixels" Value="True" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ComboBoxItem">
<Border x:Name="ItemBorder" Padding="2,0" BorderThickness="1" CornerRadius="3" TextBlock.FontSize="18.333" >
<ContentPresenter />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</UserControl.Resources>
Please let me know if you need any more information.
And here is the result:

Im struggling with a problem that might seem easy first: I want to display some grid with different colors. I have a listview that is binded to a list. The list containst Colors (i have tried SolidColorBrush as well). The listview can display the elements, so in the current case you can see 1 grid per item. I want to bind the background of the grid (so the datatemplate) to the color property itself. For example: lets say i have a white and black color in my list. Then i want to display a black and a white grid using listview.
However, i cannot bind the background to anything, the binding always fails and I couldnt find a solution.
Here is the xaml code:
<ListView ItemsSource="{Binding lightColors}" Height="30" HorizontalAlignment="Left">
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="Margin" Value="5"></Setter>
<Setter Property="Background" Value="{Binding **WHAT TO WRITE HERE?**}"></Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListViewItem">
<Grid Height="30" Width="30"></Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ListView.ItemContainerStyle>
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel>
</WrapPanel>
</ItemsPanelTemplate>
</ListView.ItemsPanel>
<ListView.ItemTemplate>
<DataTemplate>
</DataTemplate>
</ListView.ItemTemplate>
And some code snippets:
public List<Color> lightColors { get; set; }
public void fillLightColors()
{
Color myColor = Color.FromRgb(100, 150, 75);
LightColor.Add(myColor);
}
Currently i cant see anything whenever i try to bind to the background.
Maybe im missing something obvious, maybe i have to use something totally else. Any help would be appriciated!
You would use a SolidColorBrush as value of the Setter:
<Setter Property="Background">
<Setter.Value>
<SolidColorBrush Color="{Binding}"/>
</Setter.Value>
</Setter>
Besides that, the ControlTemplate must also use the Background property:
<ControlTemplate TargetType="ListViewItem">
<Grid Height="30" Width="30"
Background="{TemplateBinding Background}"/>
</ControlTemplate>
Also note that when you set the ListViewItem's Template like this, the ItemTemplate is not used at all. The ControlTemplate should have a ContentPresenter.
<ControlTemplate TargetType="ListViewItem">
<Grid Height="30" Width="30"
Background="{TemplateBinding Background}">
<ContentPresenter/>
</Grid>
</ControlTemplate>
How about this:
Style:
<Style x:Key="ColorComboStyle" TargetType="{x:Type ComboBox}">
<Setter Property="ItemsSource" Value="{Binding Path=(global:GlobalVars.AllBrushes)}"/>
<Setter Property="SelectedValuePath" Value="Name"/>
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
<Setter Property="ItemTemplate">
<Setter.Value>
<DataTemplate>
<Grid HorizontalAlignment="Stretch" Height="24">
<DockPanel LastChildFill="True" HorizontalAlignment="Stretch">
<Rectangle DockPanel.Dock="Right" Fill="{Binding}" Stroke="Black" StrokeThickness="1" Height="20" Width="20"/>
<Label Padding="2" Content="{Binding}" VerticalAlignment="Center" HorizontalAlignment="Left"/>
</DockPanel>
</Grid>
</DataTemplate>
</Setter.Value>
</Setter>
<Setter Property="ItemContainerStyle">
<Setter.Value>
<Style TargetType="{x:Type ComboBoxItem}">
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
</Style>
</Setter.Value>
</Setter>
</Style>
The GlobarVars property looks like this:
public static List<string> AllBrushes { get; } = typeof(Brushes).GetProperties().Select(x => x.Name).ToList();
Then use a ComboBox like this:
<ComboBox Style="{StaticResource ColorComboStyle}" SelectedValue="{Binding ...}"/>
Worked very well in my case... You will just need to adapt the code to work in your ListView.
I'm new to wpf and xaml,
trying to understand the basic concepts by writing a simple app using MVVM.
One thing I can't wrap my head around is
How to bind a control eg. textBox which is defined in a style to a viewModel from the control which uses this style?
Style Example (I like to bind the textBox named "SearchBox"):
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Style TargetType="{x:Type TextBox}"
x:Key="FlatSearchBox">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBox}">
<Border CornerRadius="10"
Background="#353340"
Width="200" Height="40">
<Grid>
<Rectangle StrokeThickness="1"/>
<TextBox Margin="1"
Text="{TemplateBinding Text}"
BorderThickness="0"
Background="Transparent"
VerticalContentAlignment="Center"
Padding="5"
Foreground="#CFCFCF"
x:Name="SearchBox"/>
<TextBlock Grid.Column="1"
IsHitTestVisible="False"
Text="Search"
VerticalAlignment="Center"
HorizontalAlignment="Left"
Margin="10,0,0,0"
FontSize="11"
Foreground="DarkGray">
<TextBlock.Style>
<Style TargetType="{x:Type TextBlock}">
<Style.Triggers>
<DataTrigger Binding="{Binding Text, ElementName=SearchBox}" Value="">
<Setter Property="Visibility" Value="Visible"/>
</DataTrigger>
</Style.Triggers>
<Setter Property="Visibility" Value="Hidden"/>
</Style>
</TextBlock.Style>
</TextBlock>
</Grid>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Part of XAML in which the style is applied to a textBox:
<TextBox Grid.Row="2" Grid.Column="2"
VerticalAlignment="Center"
FontSize="20"
Style="{StaticResource FlatSearchBox}"
Text="{Binding CurrentFinanceModel.Value, UpdateSourceTrigger=PropertyChanged, Converter={StaticResource currencyConverter}}"/>
The text binding should apply to the textBox named "SearchBox" in the style.
Hope the question is clear and I did not make a mistake, because it's my first question here :)
Thanks!
I am new to WPF and some help would be appreciated.
I got a resource Dictionary where I am trying to style a ListViewItem or ItemTemplate ListView's Property, But both ways have failed.
First way:
Dictionary
<Style TargetType="ListViewItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<StackPanel Orientation="Horizontal">
<Ellipse Height="45" Width="45" Fill="Gray"/>
<ContentPresenter/>
</StackPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
MainWindow
<ListView Grid.Row="1" Background="LightSkyBlue">
<ListViewItem>Text cannot be seen</ListViewItem>
</ListView>
"This one doesn't show any text"
Second Way:
Dictionary
<DataTemplate x:Key="LeftMenuButtons">
<StackPanel Orientation="Horizontal">
<Ellipse Height="45" Width="45" Fill="Gray"/>
<ContentPresenter/>
</StackPanel>
</DataTemplate>
MainWindow
<ListView ItemTemplate="{StaticResource LeftMenuButtons}" Grid.Row="1" >
<ListViewItem>No Effect for DataTemplate Only Text Appears</ListViewItem>
</ListView>
This Doesn't apply anything in DataTemplate.
If possible I would like to know what is going wrong in both two ways ... Thanks in advance.
First Way - Control Template
Please specify the TargetType of the control template explicity.
<ControlTemplate TargetType="{x:Type ListViewItem}">
You could also give the list view item style a name, so it is not applied on all items in your scope, but only to the target list view.
<Style x:Key="ListViewItemStyle"
TargetType="ListViewItem">
Make sure, that you assign the style to your target list view.
<ListView Grid.Row="1"
Background="LightSkyBlue"
ItemContainerStyle="{StaticResource ListViewItemStyle}">
Second Way - Data Template
First, data templates only work if your items are assigned via the ItemsSource property. If you directly assign ListViewItems to your list view, they will not be affected. You have to bind the ItemsSource to a collection. Second, you do not use a ContentPresenter in the data template, you bind to properties of the objects in the ItemsSource collection. In this example you would have a collection of strings that are assigned to the Text property of the TextBlock. Maybe this is beyond the scope of your question.
<ListView Grid.Row="1"
ItemsSource="{Binding StringCollection}"
ItemTemplate="{StaticResource LeftMenuButtons}"/>
<DataTemplate x:Key="LeftMenuButtons"
<StackPanel Orientation="Horizontal">
<Ellipse Height="45"
Width="45"
Fill="Gray"/>
<TextBlock Text="{Binding}"/>
</StackPanel>
</DataTemplate>
The code below works. You just forgot to write ControlTemplate TargetType.
<Style x:Key="ListViewItemStyle" TargetType="ListViewItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListViewItem}">
<StackPanel Orientation="Horizontal">
<Ellipse Height="45" Width="45" Fill="Gray"/>
<ContentPresenter/>
</StackPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
I want to change my WPF & C# code to telerik. Before change i have HeaderContentControl with some Workspaces
My XAML code
<HeaderedContentControl
Content="{Binding Workspaces}"
ContentTemplate="{StaticResource WorkspacesTemplate}"
Style="{StaticResource MainHCCStyle}"
/>
My Resources
<Style x:Key="MainHCCStyle" TargetType="{x:Type HeaderedContentControl}>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type HeaderedContentControl}>
<DockPanel>
<ContentPresenter
ContentSource="Content"
ContentTemplate="{TemplateBinding ContentTemplate}"
/>
</DockPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<DataTemplate x:Key="WorkspacesTemplate">
<TabControl
IsSynchronizedWithCurrentItem="True"
ItemsSource="{Binding}"
ItemTemplate="{StaticResource ClosableTabItemTemplate}"
Margin="4"
/>
</DataTemplate>
After modify code to Telerik my code looks like
My XAML code
<telerik:RadTabbedWindow
Content="{Binding Workspaces}"
ContentTemplate="{StaticResource WorkspacesTemplate}"
telerik:StyleManager.Theme="Office2016"
Style="{StaticResource MainHCCStyle}"
/>
My Resources
<Style x:Key="MainHCCStyle" TargetType="{x:Type telerik:RadTabbedWindow}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type telerik:RadTabbedWindow}">
<DockPanel>
<ContentPresenter
ContentSource="Content"
ContentTemplate="{TemplateBinding ContentTemplate}"
/>
</DockPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<DataTemplate x:Key="WorkspacesTemplate">
<TabControl
IsSynchronizedWithCurrentItem="True"
ItemsSource="{Binding}"
ItemTemplate="{StaticResource ClosableTabItemTemplate}"
Margin="4"
/>
</DataTemplate>
Workspaces wors ok, but Telerik theme doesn't work ( telerik:StyleManager.Theme="Office2016"). Styles only activate if I delete them Style="{StaticResource MainHCCStyle}", however then workspaces doesn't work
The custom Style that targets RadTabbedWindow is overriding its ControlTemplate (via the Template property). This means that the default look and feel of the control is replaced with the Dock panel defined in the Style.
To make this work, set the ContentTemplate of RadTabbedWindow, instead of its Template property.
I would like to create a style that could be applied to any ContentControl which would take the ToolTip and add an image to the ContentControl and apply the tool tip text from the object to the image. I have about a hundred of these that need to be done (in various projects) so being able to create a style would save a lot of typing.
What I am trying to recreate is this (ToolTip text is on the blue 'i' and not the 'Reload Employee Data':
which is accomplished via the following:
<StackPanel Orientation="Horizontal">
<CheckBox Content="Reload Employee Data"
IsChecked="{Binding AdjustmentSettings.ReloadEmployeeData}"
Grid.Row="0"
Grid.Column="0">
</CheckBox>
<Image Source="/DelphiaLibrary;Component/Resources/info.ico"
ToolTip="Check if you want to re-upload ..."/>
</StackPanel>
What I am trying to avoid is creating a new stack panel each time I want to add the blue 'i' with the tool tip text on the 'i' and not on the text of the object.
I was able to create the following that works for a Label:
<!-- Works for just Label -->
<Style x:Key="LabelToolTipStyle"
TargetType="{x:Type Label}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Label">
<StackPanel Orientation="Horizontal">
<TextBlock Text="{TemplateBinding Content}" />
<Image Source="info.ico" ToolTip="{TemplateBinding ToolTip}"/>
</StackPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
And I can call this simply by adding the style to the label like so:
<Label Content="First Text" Style="{StaticResource LabelToolTipStyle}" ToolTip="Label with LabelToolTipStyle" />
I then tried to make this more generalized by creating a style targeting ContentControl but obviously doesn't work because this overrides the entire template (in the case of CheckBox control, the checkbox is missing):
<!-- Works on Label but not CheckBox -->
<Style x:Key="ContentToolTipStyle"
TargetType="{x:Type ContentControl}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ContentControl">
<StackPanel Orientation="Horizontal">
<TextBlock Text="{TemplateBinding Content}" />
<Image Source="info.ico" ToolTip="{TemplateBinding ToolTip}"/>
</StackPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Is there a way that I could create a style for ContentControls that would allow me to ADD to the template without redefining the entire template? If it cannot be done to ContentControl I wouldn't be opposed to creating a separate style for each control type but would like to avoid redefining the entire template to do so.
You are almost there. You need to create a custom control template for a ContentControl:
<Style x:Key="ToolTipWrapper" TargetType="{x:Type ContentControl}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ContentControl}">
<StackPanel Orientation="Horizontal">
<StackPanel.ToolTip>
<ToolTip Visibility="Hidden" />
</StackPanel.ToolTip>
<ContentPresenter />
<Image Source="info.ico" ToolTip="{TemplateBinding ToolTip}" />
</StackPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Then wrap your elements in a ContentControl and apply the style:
<ContentControl Style="{StaticResource ToolTipWrapper}" ToolTip="Hello world">
<CheckBox Content="I am a check box" />
</ContentControl>
What you can't do is to automatically apply the custom style to all "content" controls: you will always need the extra ContentControl wrapped around each element you want to style in this way.
