How to expand values?


You need to create your custom control with Dependency Property from C#.
DependencyProperty.Register("My_Property_Name_1", typeof(String), typeof(Custom_Control));
DependencyProperty.Register("My_Property_Name_2", typeof(String), typeof(Custom_Control));

In Wpf how to avoid/disable mouse hover a button highlight color?

I wonder if there is a way to do it for all the future buttons and other controls or do i need to make a solution for each control/button ? And how to do it ?
I want to disable the mouse hove highlight.
<Button x:Name="btnTest" Content="Start Watching" HorizontalAlignment="Left" Margin="14,241,0,0" VerticalAlignment="Top" Width="109" RenderTransformOrigin="0.484,-0.066" Height="30" FontSize="16" Background="#FFFB0000" Click="btnTest_Click"/>
<TextBox HorizontalAlignment="Left" Height="30" Margin="14,175,0,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="644"/>
<Button Content="Browse" Margin="673,175,18,0" VerticalAlignment="Top" RenderTransformOrigin="-0.111,0.769" Height="30" FontSize="16"/>

Add it to your ResourceDictionary:
<Style TargetType="Button">
<Setter Property="OverridesDefaultStyle" Value="True"/>
<Setter Property="Margin" Value="5"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border Name="border"
BorderThickness="1"
Padding="4,2"
BorderBrush="DarkGray"
CornerRadius="3"
Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="border" Property="BorderBrush" Value="Black" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
And since Style has no key it will be on all the buttons

You'll need to create a style. if you want it to be applied through your whole app, you'll need to put it into your "app.xaml" file (within an application.Resources).
Bellow is an example of how to do it. I added some stuff like setters to illustrate that you can add properties, you could also add triggers and many things.
Not setting a "x:key" to your style will make them the default one (thus overriding the basic one), as the one below, if you wish to have a collection of styles, give them keys.
`<Style TargetType="{x:Type Button}">
<Setter Property="Background"
Value="Transparent" />
<Setter Property="BorderThickness"
Value="0" />
<Setter Property="Cursor"
Value="Hand" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<ContentPresenter HorizontalAlignment="Center"
VerticalAlignment="Center">
</ContentPresenter>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>`

Change Border Thickness by Xaml, `wpf`

Please keep in mind i am new with WPF, I am trying to give my Button a border thickness value via .Xaml templates, However, its not working, Here is my .Xaml:
<Button>
<Button.Style>
<Style TargetType="{x:Type Button}">
<Setter Property="Background" Value="#FFFFFFFF" />
<Setter Property="Foreground" Value="#FFF01F1F" />
<Setter Property="BorderBrush" Value="#FFF01F1F" />
<Setter Property="BorderThickness" Value="5" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Background" Value="#FFF01F1F" />
<Setter Property="Foreground" Value="#FFFFFFFF" />
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
Thanks in Advance.
Update:::
I have tried the Change Thickness answer, however now it disables my IsMouseOver property,

You set your own custom template which doesn't use the BorderThickness property of the button itself, so it should be:
<Border Background="{TemplateBinding Background}" BorderThickness="{TemplateBinding BorderThickness}">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
Or you can set it to 5 directly on the template.

Setting border size on button on mouse over in WPF

I am trying to set the border colour property on a button when user hovers on it. Currently I am using following XAML.
<Button.Style>
<Style TargetType="{x:Type Button}">
<Setter Property="Background" Value="#FF0081a7"/>
<Setter Property="BorderBrush" Value="White"/>
<Setter Property="BorderThickness" Value="2,2,2,2"/>
<Setter Property="Foreground" Value="#FFffffff"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="#ccCCCCCC"/>
<Setter Property="BorderBrush" Value="Gold"/>
<Setter Property="BorderThickness" Value="2,2,2,2"/>
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
This works fine only for colour changes. Border on the other hand is not displayed at all. I am sure, I am missing something very simple, only thing is I can't find what it is.

You're not actually utilising the BorderBrush and BorderThickness properties... you need to actually do something with them from inside your ControlTemplate. Try this:
<ControlTemplate TargetType="{x:Type Button}">
<Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding
BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
</ControlTemplate>

How to change the background of a GridSplitter when focused/dragged in XAML (with a border)?

I found it weird that there's no GridSplitter property like "DragBackground" or something alike.
This seems to work though:
<UserControl.Resources>
<Style x:Key="CustomGridSplitterStyle" TargetType="GridSplitter">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="GridSplitter">
<Grid x:Name="Root" >
<!-- Background -->
<Rectangle Fill="White" StrokeThickness="0" />
<!-- Focus Visual -->
<Rectangle x:Name="FocusVisual" Stroke="White" StrokeThickness="1" Opacity="0" IsHitTestVisible="false" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</UserControl.Resources>
 
GridSplitter Style="{StaticResource CustomGridSplitterStyle}" Grid.Column="1" Width="6" HorizontalAlignment="Stretch"
BorderThickness="2,0,0,0" BorderBrush="Blue" />
My problem with this solution however is that I'd like to set a border on the left side of the GridSplitter (see above), which doesn't work when using the custom GridSplitter style.
Does anybody know how to get this working ?

If you want to use BorderBrush and BorderThickness in your Template you can use TemplateBinding on some Border. You can also use Setter in your Style to define some default value.
<Style x:Key="CustomGridSplitterStyle" TargetType="{x:Type GridSplitter}">
<Setter Property="Background" Value="White"/>
<Setter Property="BorderBrush" Value="White"/>
<Setter Property="BorderThickness" Value="0"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="GridSplitter">
<Border
x:Name="FocusVisual"
Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}"/>
<ControlTemplate.Triggers>
<Trigger Property="IsDragging" Value="True">
<Setter TargetName="FocusVisual" Property="..." Value="..." />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Also since GridSplitter is a Thumb and as such has IsDragging property so you can create Trigger to do something when it is true as in the example above

Change WPF control's ControlTemplate to not be disabled

I have a Devexpress DateEdit and added a trigger for when IsEnabled=False to change the ControlTemplate to be a Label. This all works fine, but my problem is, that the Text of the Label is still Grayed out(Disabled).
My style:
<Style x:Key="DateTimeDropDownStyle" TargetType="{x:Type dxe:DateEdit}">
<Setter Property="Mask" Value="dd MMM yyyy"/>
<Setter Property="MaskUseAsDisplayFormat" Value="True"/>
<Style.Triggers>
<Trigger Property="dxe:DateEdit.IsEnabled" Value="False">
<Setter Property="dxe:DateEdit.Template">
<Setter.Value>
<ControlTemplate>
<Label Content="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Text, StringFormat={}{0:dd MMM yyyyy}}"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
</Style>
So, my question is, how do i change the Style so that the Label is not disabled?

Try setting Foreground on the Label in your template.
If it doesn't help, you'd have to edit the control template for the label. A basic one is:
<ControlTemplate TargetType="{x:Type Label}">
<Border Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}">
<ContentPresenter Margin="{TemplateBinding Padding}"/>
</Border>
<ControlTemplate.Triggers>
<!--This is the trigger to remove-->
<Tirgger Property="IsEnabled"
Value="False">
<Setter Property="Foreground"
Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
