I have the following Window bar with four buttons and one image (a littlebit like ribbon):
this is the code (XAML) and the code behind (in C#) is not interesting :
<Button Style="{StaticResource {x:Static ToolBar.ButtonStyleKey}}" Focusable="False"
Click="SaveClicked" Margin="10, 0">
<StackPanel Orientation="Horizontal" >
<Image x:Name="ImageSave" Height="20" VerticalAlignment="Bottom" HorizontalAlignment="Left" Width="20"
Source="images/titlebar/SaveIconWhite.png" Margin="0,0,0,5" />
<Label x:Name="LbSave" Content="Save" VerticalAlignment="Stretch" FontSize="14"
HorizontalAlignment="Left" Foreground="White" />
</StackPanel>
<Button.Template>
<ControlTemplate TargetType="Button">
<ContentPresenter Content="{TemplateBinding Content}"/>
</ControlTemplate>
</Button.Template>
</Button>
The code is nearly the same for the other buttons.
The buttons feel a littlebit unhandy because they have no mouseover effects.
I would like to implement a color change of the labels when the mouse is over the buttons. a change of the images for file load and save would be great too, but i think i am able to do it myself when i know how to implement the mouse over color change of the label.
under normal conditions i'd try to archieve a mouse over color change with these code:
<Button.Style>
<Style TargetType="Button" BasedOn="{StaticResource {x:Type Button}}">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="DarkGoldenrod"/>
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
But this does not work, because i already have the Button.Template and i am also a littlebit confused about the Button.Template at all (haven't understood it - only copied..). How is the Button.Template working and what is it usage?
Is anybody able to give me a hint in the right direction?
We have MouseEnter and MouseLeave Events.
Use MouseEnter to Change the Color When Mouse is inside control.
Use MouseLeave to Change back the Color When Mouse comes out of the control.
Never Used but Put Trigger inside ControlTemplate of button:
Something Like This:
<Button.Template>
<ControlTemplate TargetType="Button">
<ContentPresenter Content="{TemplateBinding Content}"/>
<ControlTemplate.Triggers>
<Trigger Property="Button.IsMouseOver" Value="True">
<Setter TargetName="buttonLabel" Property="Foreground" Value="Red"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Button.Template>
</Button>
and How is the Button.Template working and what is it usage?

So im trying to make button appear on right click in my ListBox.
<ListBox Grid.Column="1" Margin="358,44,20,63" Name="scriptbox" Background="#FF282828" Foreground="White" SelectionChanged="Scriptbox_SelectionChanged" BorderThickness="0">
<ListBox.ContextMenu>
<ContextMenu>
<MenuItem
Template="{DynamicResource MenuItemTemplate}"
Header="Delete"
Click="MenuItemDelete_Click" >
</MenuItem>
</ContextMenu>
</ListBox.ContextMenu>
This is my MenuItem template.
<ControlTemplate TargetType="{x:Type MenuItem}" x:Key="MenuItemTemplate">
<Border x:Name="Border" Background="#FF282828" Padding="30,5,30,5" BorderThickness="0" Margin="0">
<ContentPresenter ContentSource="Header" x:Name="HeaderHost" RecognizesAccessKey="True" />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsHighlighted" Value="true">
<Setter Property="Background" TargetName="Border" Value="#51544e"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
<ItemsPanelTemplate x:Key="MenuItemPanelTemplate">
<StackPanel Margin="-3,0,0,0" Background="White"/>
</ItemsPanelTemplate>
<Style TargetType="{x:Type MenuItem}">
<Setter Property="ItemsPanel" Value="{StaticResource MenuItemPanelTemplate}"/>
</Style>
Everything is fine but there is white border all around the button.
What you recognize as a white border is the ContextMenu itself that contains your MenuItems. Try adding more buttons and changing the Background and BorderBrush of the ContextMenu and you will see.
<ContextMenu Background="Red" BorderBrush="Blue">
Changing the brushes like this will lead to this result, which makes it obvious.
If you create a custom control template for your MenuItems you should probably do so for the ContextMenu, too, if only setting brushes does not fit your requirements. As you can see in the example, there is still a vertical white line that is part of the default control template, that you might want to get rid of. You can start from this example, although it is neither the default template nor complete. Look at this related post for guidance on how to extract the default control template for ContextMenu if you need it.
In the current WPF application that I am working on, I have to invert the color of an icon when the mouse is pressed on (when property isPressed=true ). The reason why I need to do is I want to keep the consistency of the application with regard to the icon color and background. But this icon is embedded within a button which when clicked displays a similar color and hence the icon is not visible
As my style trigger picks up the red color that I have set but the color of the geometry is not changed. Is there any way I can use this style trigger to set the color of the geometry also to Red when (isPressed=true)?
Here is my code
My Style is as follows
<Style x:Key="ButtonBackground" TargetType="{x:Type Button}">
<Style.Triggers>
<Trigger Property="IsPressed" Value="True">
<Setter Property="Foreground" Value="Red" />
<Setter Property="Content" Value="yellow" />
</Trigger>
</Style.Triggers>
</Style>
I tried setting a setter property to content as yellow just to see if it works but it did not work
The part where it is being used is as follows
<Border BorderBrush="{StaticResource ContentBackground}" BorderThickness="0,0,0,1">
<Button
x:Name="NameButton"
Style="{StaticResource ButtonBackground}"
>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<StackPanel Grid.Column="0" Orientation="Horizontal">
<ContentControl x:Name="Icon"
Width="25"
Height="25"
">
</ContentControl>
<TextBlock Text="{Binding Name}"
"/>
</StackPanel>
</Grid>
</Button>
</Border>
As shown in the images as well the style is picked up by the textblock but I do not know how I can add this style to the contentcontrol which has the icons
Edit :- Example of icon specified in the application
<DataTemplate x:Key="FolderIcon">
<Path
Fill="#047F89"
Data="....."/>
</DataTemplate>
You have to bind the Fill property of the Path to the parent Control element's Control.Foreground (or Button.Foreground) instead of setting it directly. Now the icon color will adapt to the Foreground value assigned by the trigger. I also removed the redundant Grid of the Button.Content and the Content Setter of the Trigger as it would remove the icon Path element every time the Button is pressed and added the default Forground value to the Style (moved from Path.Fill to Style-Setter):
<Style x:Key="ButtonBackground" TargetType="{x:Type Button}">
<Setter Property="Foreground" Value="#047F89" />
<Style.Triggers>
<Trigger Property="IsPressed" Value="True">
<Setter Property="Foreground" Value="Red" />
</Trigger>
</Style.Triggers>
</Style>
<Button x:Name="NameButton"
Style="{StaticResource ButtonBackground}">
<Button.Content>
<StackPanel Orientation="Horizontal">
<Path Fill="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=Control}, Path=Foreground}"
Height="16"
Width="16"
Stretch="Uniform"
VerticalAlignment="Center"
Margin="5,0,0,0"
Data="....."/>
<TextBlock Text="{Binding Name}"
TextTrimming="WordEllipsis"
VerticalAlignment="Center"
Margin="5,0,0,0"/>
<StackPanel>
<Button.Content>
</Button>
The Binding on Path.Fill would still work in case you decide to move the Path to a ResourceDictionary.
This will probably be very simple for most of you, I am new to XAML and WPF.
I have an app that startes att full screen, I did this by adding
WindowState="Maximized"
WindowStyle="None"
I want to have a button that simply eliminates this part. I have a "Full screen" button in the xaml and by click he is calling a "FullScreen_Click" function in my code.
I just need to know what to write in the code that will eliminate the full screen if it is on full screen mode and restore it to full screen when it is not.
Try this:
private void FullScreen_Click(object sender, RoutedEventArgs e)
{
WindowState = WindowState == WindowState.Maximized ? WindowState.Normal : WindowState.Maximized;
}
This will toggle between WindowState.Maximized and WindowState.Normal each time the Button is clicked.
For a xaml only technique just for reference to see a xaml example in comparison (but I would do #mm8's route, it's simpler);
1. Bind your property to that of another like:
<Window WindowState="{Binding Tag, ElementName=toggleState}" .... />
2. Use a `ToggleButton` or similar control and `Triggers`
.
<!-- like this PoC -->
<Grid>
<Grid.Resources>
<Style x:Key="cwWindowState_PoC" TargetType="{x:Type ToggleButton}">
<Setter Property="Tag" Value="Maximized"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ToggleButton">
<Grid>
<Border Background="{TemplateBinding Background}"/>
<ContentPresenter x:Name="MyContentPresenter"
Content="{TemplateBinding Tag}"
HorizontalAlignment="Center"
VerticalAlignment="Center" />
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter Property="Tag" Value="Normal" />
</Trigger>
<Trigger Property="IsChecked" Value="False">
<Setter Property="Tag" Value="Maximized" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Grid.Resources>
<ToggleButton x:Name="toggleState" Content="Click Me"
Background="Green"
Style="{StaticResource cwWindowState_PoC}"/>
</Grid>
Could also use DataTrigger but that requires interaction triggers instead of just a property setter from a template.
I am using a DEVExpress combobox and have enabled type ahead (Auto search functioanlity). In combo box I am showing two things. First item is an image and second item is a value(id).
Mine problem is that the value border is getting outside to combo box while showing at UI at run time. I tried setting margin but its of no use. My application is having option to select theme and for some of the theme its getting hazy.
Any idea how to get rid of this ?
see the first one is looking fine however the below one is bit hazy if i change the theme.
I am using below code for the same.
<dvEx:ComboBoxEdit.EditTemplate>
<ControlTemplate>
<StackPanel Orientation="Horizontal">
<Image Source="{Binding Path=(dxe:BaseEdit.OwnerEdit).SelectedItem.Image, RelativeSource={RelativeSource Self}}" Margin="8, 0, 4, 0"/>
<TextBox x:Name="PART_Editor" BorderBrush="Transparent"/>
</StackPanel>
</ControlTemplate>
</dvEx:ComboBoxEdit.EditTemplate>
<dvEx:ComboBoxEdit.ItemTemplate>
<DataTemplate DataType="{x:Type vm:DesignSelectViewModel}">
<StackPanel Orientation="Horizontal">
<Image Source="{Binding Image}" Margin="8, 0, 4, 0"/>
<TextBlock Text="{Binding Name}"/>
</StackPanel>
</DataTemplate>
</dvEx:ComboBoxEdit.ItemTemplate>
To accomplish your task I suggest you to override the TextBox.Template as follows to make it theme-independent and remove it's focused state (border and background):
<TextBox x:Name="PART_Editor">
<TextBox.Template>
<ControlTemplate TargetType="{x:Type TextBox}">
<Grid x:Name="Root" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}">
<ScrollViewer x:Name="PART_ContentHost" Margin="1" Padding="{TemplateBinding Padding}"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsReadOnly" Value="True">
<Setter Property="Opacity" TargetName="PART_ContentHost" Value="0.75"/>
</Trigger>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Opacity" TargetName="Root" Value="0.5"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</TextBox.Template>
</TextBox>

I have the following code in the Window.Resources of a WPF window. What it is basically doing is creating an item that represents a grid with a label positioned on the left and a button on the right. When I mouse over the label or the button the row changes color as expected but I want it to also change color if the mouse is over any of the row.
How can this be achieved?
Any help is appreciated.

<Style x:Key="alternatingWithTriggers"
TargetType="{x:Type ContentPresenter}">
<Setter Property="Height" Value="25"></Setter>
</Style>
<Style x:Key="onmouseover" TargetType="{x:Type DockPanel}">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Yellow">
</Setter>
</Trigger>
</Style.Triggers>
</Style>
<DataTemplate x:Key="ItemTemplate">
<Border x:Name="ItemBorder" HorizontalAlignment="Stretch" BorderThickness="0" Background="#BBB" ClipToBounds="True" >
<DockPanel ClipToBounds="True" HorizontalAlignment="Stretch" Style="{StaticResource onmouseover}">
<Label Content="{Binding Name}" HorizontalAlignment="Left" Height="80"></Label>
<Button Content="Delete" HorizontalAlignment="Right" Margin="0,0,10,0"/>
</DockPanel>
</Border>
...
Give the DockPanel Background="Transparent". That should allow it to capture mouse events.
I don't see anything obviously wrong in the snippet you've posted, and since I'm not in front of Studio, I can't try it out, but if I were you, I'd try adding a MouseEnter handler on the DockPanel (just throw the do-nothing handler in the code-behind for the view, since you'll remove it later).
Make sure that handler is getting hit when you enter, and with the debugger/immediate window, make sure the IsMouseOver property is as you expect it to be. That will at least direct your next debugging steps:
If IsMouseOver is true and your handler is hit, then my guess would be something about the trigger you've got set up isn't quite right.
If IsMouseOver is false or your handler isn't hit, then my guess would be something like IsHitTestVisible is set to false or something of that sort.
Just for fun, I'd also try moving the style declaration inline to the dockpanel, just to make sure, like so:
<DataTemplate x:Key="ItemTemplate">
<Border x:Name="ItemBorder" HorizontalAlignment="Stretch" BorderThickness="0" Background="#BBB" ClipToBounds="True" >
<DockPanel ClipToBounds="True" HorizontalAlignment="Stretch">
<DockPanel.Style>
<Style TargetType="{x:Type DockPanel}">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Yellow"/>
</Trigger>
</Style.Triggers>
</Style>
</DockPanel.Style>
<Label Content="{Binding Name}" HorizontalAlignment="Left" Height="80"></Label>
<Button Content="Delete" HorizontalAlignment="Right" Margin="0,0,10,0"/>
</DockPanel>
</Border>
