I tried many different options to change the backgroundcolor on hover, but it dosen't work for me.
Here is my code:
<Button x:Name="bAction" HorizontalAlignment="Center" Margin="0,500,0,0" VerticalAlignment="Center" Height="100" Width="1000" BorderBrush="Black" OpacityMask="White" Background="#FF5B5B5B" IsDefault="True" Click="bAction_Click">
<TextBlock x:Name="tbAction" TextWrapping="Wrap" Text="Test" Foreground="White" IsEnabled="False" Width="990" Height="85" FontFamily="Letter Gothic Std" FontSize="21.333" FontWeight="Bold" TextDecorations="{x:Null}" TextAlignment="Center"/>
</Button>
Try applying the below style to Button
<Style x:Key="myStyle" TargetType="Button">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver"
Value="True">
<Setter Property="Background"
Value="Red" />
</Trigger>
</ControlTemplate.Triggers>
<ContentPresenter />
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

I don't understeand why this code doesn't work.
The button color is still default when I hover my mouse over it.
<Window>
<Window.Resources>
<Style x:Key="hover" TargetType="Button">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Red" />
</Trigger>
</Style.Triggers>
</Style>
</Window.Resources>
<Grid>
<Button
Width="144"
Height="58"
Margin="320,177,0,0"
HorizontalAlignment="Left"
VerticalAlignment="Top"
Content="Button"
Style="{StaticResource hover}" />
</Grid>
</Window>
it is necessary to modify the ControlTemplate to activate the IsMouseOver event like this :
<Button Width="144" Height="58" Margin="320,177,0,0" HorizontalAlignment="Left" VerticalAlignment="Top" Content="Button" >
<Button.Style>
<Style TargetType="Button">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border Background="{TemplateBinding Background}" BorderBrush="Black" BorderThickness="1">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Red"/>
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
I am trying to build a text filter for a list in a popup, and notify the user when the filter is active by changing the color of the button that opens the popup.
I am using an MVVM lite setup and a XAML style sheet to reference the desired styles. Up until this point I have created the popup and the controlling button, and I have been able to put a mouse over trigger on the button and have it work. However when I tried to have a datatrigger set to the value of the textbox in the popup, it does not respond at all.
Here is the XAML code in the View for the button and the popup:
<StackPanel Orientation="Horizontal" Grid.Column="1" HorizontalAlignment="Center" >
<TextBlock HorizontalAlignment="Center" Text="Filter Popup" />
<Button x:Name="PopUpControl" Tag="popup" Style="{StaticResource FilterButtonStyle}" Command="{Binding OpenPopupCommand}" IsEnabled="{Binding IsFilterEnabled, UpdateSourceTrigger=PropertyChanged}" Margin="2,1,2,1" VerticalAlignment="Top"/>
</StackPanel>
<Popup x:Name="textPopup" IsOpen="{Binding IsFilterPopupOpen, Mode=TwoWay}" PlacementTarget="{Binding ElementName=PopUpControl}" Placement="Bottom" Width="Auto" StaysOpen="False" Margin="2 2 2 2">
<TextBox x:Name="TextValue" Grid.Column="0" BorderThickness="1" Style="{StaticResource WatermarkedTextBox}" Margin="2,4" VerticalAlignment="Center" Tag="Text Filter" Text="{Binding FilterSearch, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True}"
<Button Grid.Column="4" Style="{StaticResource SearchIconStyle}" IsEnabled="{Binding FilterEnabled, Mode=TwoWay}" Command="{Binding ApplyFilterCommand}" Margin="19,6" Grid.ColumnSpan="2" />
</Grid>
</Popup>
Here is the style for the button:
<Style x:Key="SortButtonStyle" TargetType="{x:Type Button}">
<Setter Property="Width" Value="15"/>
<Setter Property="Height" Value="15"/>
<Setter Property="VerticalAlignment" Value="Bottom"/>
<Setter Property="Margin" Value="4,0,4,0" />
<Setter Property="Tag" Value="Default" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border Name="border"
Padding="4,2"
CornerRadius="3"
Background="{DynamicResource PaleBlue}">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
<Border.OpacityMask>
<VisualBrush Visual="{StaticResource appbar_filter}" />
</Border.OpacityMask>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="border" Property="Background" Value="{DynamicResource ColumnHeaderFilterColor}" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
What I would like to happen, is when the element "TextValue" has a value in the Text field, the primary background color for the "border" changes color. Any help would be greatly appreciated.
You could use a DataTrigger that binds to the FilterSearch source property and sets a property if returns an empty string or null:
<ControlTemplate TargetType="Button">
<Border Name="border"
Padding="4,2"
CornerRadius="3"
Background="Green">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
<Border.OpacityMask>
<VisualBrush Visual="{StaticResource appbar_filter}" />
</Border.OpacityMask>
</Border>
<ControlTemplate.Triggers>
<DataTrigger Binding="{Binding FilterSearch}" Value="">
<Setter TargetName="border" Property="Background" Value="{DynamicResource PaleBlue}" />
</DataTrigger>
<DataTrigger Binding="{Binding FilterSearch}" Value="{x:null}">
<Setter TargetName="border" Property="Background" Value="{DynamicResource PaleBlue}" />
</DataTrigger>
</ControlTemplate.Triggers>
</ControlTemplate>
Hello Im trying to override the default mouseover event on WPF.
I have managed to work that out, but now having a problem displaying any Text content
Style Setter:
<Style x:Key="MyButton" TargetType="Button">
<Setter Property="OverridesDefaultStyle" Value="True"/>
<Setter Property="Cursor" Value="Hand"/>
<Setter Property="Content" Value="Submit" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border Name="Border" BorderThickness="0" BorderBrush="White" Background="#FF7AB800" Height="24" Margin="0,0,0.2,0" />
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True" >
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Heres my button code:
<Button x:Name="submitBtn" HorizontalAlignment="Left" Margin="402,296,0,0" VerticalAlignment="Top" Width="75" Foreground="Black" FontFamily="Calibri Light" FontSize="16" Style="{StaticResource MyButton}" Content="Submit"/>
You're missing the ContentPresenter. Also, I would recommend removing setting the content value from the style directly. You'd want to do this from within the control itself.
<Style x:Key="MyButton" TargetType="Button">
<Setter Property="OverridesDefaultStyle" Value="True"/>
<Setter Property="Cursor" Value="Hand"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border Name="Border"
BorderThickness="0"
BorderBrush="White"
Background="#FF7AB800"
Height="24"
Margin="0,0,0.2,0">
<ContentPresenter Margin="2"
HorizontalAlignment="Center"
VerticalAlignment="Center"
RecognizesAccessKey="True"
Content="{TemplateBinding Content}"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True" >
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<Button x:Name="submitBtn"
HorizontalAlignment="Left"
Margin="402,296,0,0"
VerticalAlignment="Top"
Width="75"
Foreground="Black"
FontFamily="Calibri Light"
FontSize="16"
tyle="{StaticResource MyButton}"
Content="Submit"/>
First of all, you need to add x: type
<Style x:Key="MyButton" TargetType="x:Type Button">
<Setter Property="SnapsToDevicePixels" Value="True"/>
<Border Name="Border" BorderThickness="0" BorderBrush="White" Background="#FF7AB800" Height="24" Margin="0,0,0.2,0" />
<ContentPresenter Content="{TemplateBinding Content}" HorizontalAlignment="Center" VerticalAlignment="Center" />
</Border>
<ControlTemplate TargetType="x:Type Button">
<StackPanel Name="StpAddDel" Orientation="Horizontal" HorizontalAlignment="Right" Margin="5">
<RadioButton Name="rdbactive" GroupName="actinact" VerticalAlignment="Center" Margin="5,0" Width="50" Height="15" Foreground="Blue">
<RadioButton.Style>
<Style TargetType="{x:Type RadioButton}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type RadioButton}">
<Grid>
<Image Source="c:\image.png" Width="32" Height="32"/>
<ContentPresenter/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</RadioButton.Style>
</RadioButton>
<RadioButton Name="rdbinactive" GroupName="actinact" VerticalAlignment="Center" Margin="5,0" Width="60" Height="15" Foreground="Blue">
<RadioButton.Style>
<Style TargetType="{x:Type RadioButton}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type RadioButton}">
<Grid>
<Image Source="c:\image.png" Width="32" Height="32"/>
<ContentPresenter/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</RadioButton.Style>
</RadioButton>
<Button Name="BtnAdd" Height="20" Width="20" Margin="5,0" Template="{StaticResource AddImgBtnTemplate}" />
<Button Name="BtnDel" Height="20" Width="20" Margin="5,0" Template="{StaticResource DelImgBtnTemplate}" />
</StackPanel>
In the above code i have 2 radio button i put images on radio buttons , My requirement is i want to change the image of the radio button after it is checked, Please help me with this......
You can use ControlTemplate.Triggers for that
<ControlTemplate TargetType="{x:Type RadioButton}">
<Grid>
<Image x:Name="PART_Image" Source="c:\image.png" Width="32" Height="32"/>
<ContentPresenter/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter TargetName="PART_Image" Property="Source" Value="new source"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
Give Image some name and change Source property of that control when IsChecked is true
EDIT
If you want to also "highlight" when mouse is over then you can add for example DropShadowEffect with another Trigger, this time when IsMouseOver is true
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="PART_Image" Property="Effect">
<Setter.Value>
<DropShadowEffect ShadowDepth="0" Color="Yellow" Opacity="0.5"/>
</Setter.Value>
</Setter>
</Trigger>

U can give your StackPanel within in your "Expander.Header" an Style with Trigger like this:
<Style x:Key="MyCustomStackPanelStyle" TargetType="{x:Type StackPanel}">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Red" />
</Trigger>
<Trigger Property="IsMouseOver" Value="False">
<Setter Property="Background" Value="Transparent" />
</Trigger>
</Style.Triggers>
</Style>
