I've been having a problem with assigning Color to GradientStop in a trigger (because trigger cannot target a GradientStop element). So I read some article about this and found solution with using Tag. Here is my code:
<Border BorderThickness="1" CornerRadius="1.5" x:Name="border">
<Border.Tag>
<Color>#FF28AAE6</Color>
</Border.Tag>
<Border.Background>
<LinearGradientBrush StartPoint="0,0" EndPoint="0,1">
<GradientStop Color="{Binding ElementName=border, Path=Tag}" Offset="0" />
<GradientStop Color="#FF0A78AA" Offset="1" />
</LinearGradientBrush>
</Border.Background>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="border" Property="Tag" Value="#FF46C8FF" />
</Trigger>
</ControlTemplate.Triggers>
But I need to set more values in that trigger - Color for the second GradientStop. How can I do it?
Why not just set the Background to the a new brush that you want it to be instead of trying to update the brush properties?
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="border" Property="Background">
<Setter.Value>
<LinearGradientBrush StartPoint="0,0" EndPoint="0,1">
<GradientStop Color="#FF46C8FF" Offset="0" />
<GradientStop Color="#FF0A78AA" Offset="1" />
</LinearGradientBrush>
</Setter.Value>
</Setter>
</Trigger>
</ControlTemplate.Triggers>
If you do need to do it your way, you could create some Canvases with Visibilty="Collapsed" and use ElementBinding to get the colours from those
<ControlTemplate>
<Border BorderThickness="1" CornerRadius="1.5" x:Name="border">
<Border.Background>
<LinearGradientBrush StartPoint="0,0" EndPoint="0,1">
<GradientStop Color="{Binding ElementName=Canvas1, Path=Tag}" Offset="0" />
<GradientStop Color="{Binding ElementName=Canvas2, Path=Tag}" Offset="1" />
</LinearGradientBrush>
</Border.Background>
<Grid>
<Canvas Name="Canvas1" Visibility="Collapsed">
<Canvas.Tag>
<Color>#FF28AAE6</Color>
</Canvas.Tag>
</Canvas>
<Canvas Name="Canvas2" Visibility="Collapsed">
<Canvas.Tag>
<Color>#FF0A78AA</Color>
</Canvas.Tag>
</Canvas>
</Grid>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="Canvas1" Property="Tag" Value="Yellow" />
<Setter TargetName="Canvas2" Property="Tag" Value="Green" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>

I try to get the look of the button like in css you can see here.
When you press this button it looks as if it goes inside.
Following is my XAML try, I used DropShadowEffect, but is not exactly like in css.
How can I achieve exactly look like in css?
Is it possible to translate CSS to XAML?

Yes, you only need to convert to XAML from CSS - by your brain.
Maybe it's a bit bloated, but it should be the most similar, welcome others to improve

Using CSS in XAML - XamlCSS
https://forums.xamarin.com/discussion/67249/xamlcss-styling-xaml-applications-with-css
I am new in WPF and trying to create some simple project.
I have created a window with a button. Then I need to create the same buttons but I cant understand how to create a template from exist button?
Here is the code:
<Grid Background="Black">
<ToggleButton x:Name="btn" Content="1" HorizontalAlignment="Left" Margin="10,10,0,0" VerticalAlignment="Top" Height="74.96" FontFamily="Digital" Width="73.8" FontSize="34.667" Foreground="White">
<ToggleButton.BorderBrush>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="Black" Offset="1"/>
<GradientStop Color="#FF5D5D5D"/>
</LinearGradientBrush>
</ToggleButton.BorderBrush>
<ToggleButton.Background>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="#FFE43DFF" Offset="0"/>
<GradientStop Color="Black" Offset="0.997"/>
</LinearGradientBrush>
</ToggleButton.Background>
</ToggleButton>
</Grid>
As we see there is single button on grid. I need to create a lot of same buttons and need a template. How to make a template? Internal question can BorderBrush be a template? I ask because in future I need to make a different buttons (like red, green, magenta etc) with the same border you can see in my code. Thanks!
You don't need a Template, you can do this with a Style:
<Window.Resources>
<Style x:Key="PurpleButton" TargetType="{x:Type ToggleButton}">
<Setter Property="BorderBrush">
<Setter.Value>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="Black" Offset="1"/>
<GradientStop Color="#FF5D5D5D"/>
</LinearGradientBrush>
</Setter.Value>
</Setter>
<Setter Property="Background">
<Setter.Value>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="#FFE43DFF" Offset="0"/>
<GradientStop Color="Black" Offset="0.997"/>
</LinearGradientBrush>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
<Grid Background="Black">
<ToggleButton x:Name="btn" Style="{StaticResource PurpleButton}" Content="1" HorizontalAlignment="Left" Margin="10,10,0,0" VerticalAlignment="Top" Height="74.96" FontFamily="Digital" Width="73.8" FontSize="34.667" Foreground="White" />
<ToggleButton Style="{StaticResource PurpleButton} Content="2" Height="74.96" FontFamily="Digital" Width="73.8" FontSize="34.667" Foreground="White"" />
</Grid>
Here is an example of a style which has triggers implemented aswell. Doing it this way using a control template you are able to create and design your own type of button.
<Style x:Key="ButtonNormal" TargetType="Button">
<Setter Property="Height" Value="40" />
<Setter Property="FontSize" Value="18" />
<Setter Property="Foreground" Value="#18272d" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border x:Name="ButtonBorder"
CornerRadius="4"
BorderThickness="1"
BorderBrush="#adcae6"
>
<Border.Background>
<LinearGradientBrush EndPoint="0.5,1.5" StartPoint="0.5,0.0">
<GradientStop Color="#ffffff" Offset="0"/>
<GradientStop Color="#e2eaf6" Offset="0.4"/>
</LinearGradientBrush>
</Border.Background>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="1.7*"/>
</Grid.RowDefinitions>
<ContentPresenter x:Name="ButtonContentPresenter"
VerticalAlignment="Center"
HorizontalAlignment="Center"
Grid.RowSpan="2" />
</Grid>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="ButtonBorder" Property="Background" >
<Setter.Value>
<LinearGradientBrush EndPoint="0.5,1.5" StartPoint="0.5,0.0">
<GradientStop Color="#d6e2f3" Offset="0"/>
<GradientStop Color="#fff" Offset="0.9"/>
</LinearGradientBrush>
</Setter.Value>
</Setter>
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter TargetName="ButtonBorder" Property="Background" >
<Setter.Value>
<LinearGradientBrush EndPoint="0.5,1.5" StartPoint="0.5,0.0">
<GradientStop Color="#bed0ed" Offset="0"/>
<GradientStop Color="#fff" Offset="0.9"/>
</LinearGradientBrush>
</Setter.Value>
</Setter>
<Setter Property="BorderBrush" Value="#7ba7d1" />
</Trigger>
<Trigger Property="IsEnabled" Value="False">
<Setter TargetName="ButtonBorder" Property="Background">
<Setter.Value>
<LinearGradientBrush EndPoint="0.5,1.5" StartPoint="0.5,0.0">
<GradientStop Color="#f6f6f6" Offset="0"/>
<GradientStop Color="#eaeaea" Offset="0.9"/>
</LinearGradientBrush>
</Setter.Value>
</Setter>
<Setter Property="Foreground" Value="DarkGray"></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
Hope this helps and gives a better overview of how Styling/Templating works.
How do I change the background of a textbox with gradient fill when it has focus?

Here is a pretty straight forward way of doing it in Xaml, using a LinearGradientBrush to set the TextBox.Background property when TextBox.IsFocused is true.
<TextBox Width="100" Height="20">
<TextBox.Style>
<Style TargetType="TextBox">
<Style.Triggers>
<Trigger Property="IsFocused" Value="True">
<Setter Property="Background">
<Setter.Value>
<LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1">
<GradientStop Color="Yellow" Offset="0.0" />
<GradientStop Color="Red" Offset="0.25" />
<GradientStop Color="Blue" Offset="0.75" />
<GradientStop Color="LimeGreen" Offset="1.0" />
</LinearGradientBrush>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
</Style>
</TextBox.Style>
</TextBox>
Edit : In your ControlTemplate.Triggers you need to add a trigger that sets the background of your ScrollViewer, try adding the following trigger to your style's ControlTemplate.Triggers.
<Trigger Property="IsFocused" Value="True">
<Setter TargetName="PART_ContentHost" Property="Background">
<Setter.Value>
<LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1">
<GradientStop Color="Yellow" Offset="0.0" />
<GradientStop Color="Red" Offset="0.25" />
<GradientStop Color="Blue" Offset="0.75" />
<GradientStop Color="LimeGreen" Offset="1.0" />
</LinearGradientBrush>
</Setter.Value>
</Setter>
</Trigger>
I have a Menu made in MVVM, but my Menuitem are big as shown here
http://i49.tinypic.com/wi1vk3.png
So in my Mainwindow I have a menu that binds to a list of menu.
In my View
<Menu VerticalAlignment="Top">
<MenuItem Header="File" ItemsSource="{Binding MenuList}" />
</Menu>
And in my ViewModel
List<MenuViewModelBase> _menuList = new List<MenuViewModelBase>();
_menuList.Add(new MenuViewModel("New", NewCommand));
_menuList.Add(new MenuViewModel("Open", OpenCommand));
_menuList.Add(new MenuViewModel("Save", SaveCommand));
_menuList.Add(new MenuViewModel("Exit", ExitCommand));
My MenuView is
<MenuItem>
<MenuItem.Resources>
<Style TargetType="MenuItem">
<Setter Property="Header" Value="{Binding Name}" />
<Setter Property="Command" Value="{Binding ActionCommand}" />
</Style>
</MenuItem.Resources>
</MenuItem>
Can someone tell me how to resize the menuitem to match their content?
I believe what you're seeing is the space the default template reserves for InputGestureText. If you want to remove that area I believe your best bet is to implement your own template for the menu item. Using the default template as a starting point it should be fairly easy to modify it to get what you're looking for.
Update:
I've included an example in which I copied the MenuItem style from the above link and added it to my project. I then removed the Icon and InputGesture areas from the SubMenuHeaderTemplate. In general, if you see default behavior that you'd like to change you can try to change via a style and if that doesn't work you can override the default template using the ones provided by Microsoft as a base.

I am planning to set the image's file destination in my code-behind (C#). For the output, the WPF button can both display the text and the image (placed in the right side of the text)
Any suggestions?
Your template includes a ContentPresenter, bound to the Content of the Button. So, you can simply set the image and/or text as the content of the button and they will go there.
<Button Style="{StaticResource ButtonStyler}">
<StackPanel Orientation="Horizontal">
<Image Source="..." />
<TextBlock Text="..." />
</StackPanel>
</Button>
just try this link. In this they created custom implementation of the button and a dependency property ImageSource so the you can use either from the code behind or from the XAML
Creating an image+text button with a control template?
