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?

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

WPF - Change background textbox with gradient

How do I change the background of a textbox with gradient fill when it has focus?
I am trying to create style for a TextBox user control that will have a gradient background when the user has gives it focus, here is what I have so far.
<Style TargetType="{x:Type TextBox}" x:Key="TextBoxNormal" >
<Setter Property="SnapsToDevicePixels" Value="True"/>
<Setter Property="OverridesDefaultStyle" Value="True"/>
<Setter Property="KeyboardNavigation.TabNavigation" Value="None"/>
<Setter Property="FocusVisualStyle" Value="{x:Null}"/>
<!--<Setter Property="MinWidth" Value="100"/>-->
<Setter Property="Height" Value="25"/>
<Setter Property="AllowDrop" Value="true"/>
<Setter Property="FontFamily" Value="Verdana"/>
<Setter Property="FontSize" Value="12" />
<Setter Property="Padding" Value="3"/>
<Setter Property="Validation.ErrorTemplate">
<Setter.Value>
<ControlTemplate>
<DockPanel LastChildFill="true">
<Border x:Name="errorBorder" Background="Red" DockPanel.Dock="right" Margin="5,0,0,0" Width="10" Height="10" CornerRadius="10"
ToolTip="{Binding ElementName=customAdorner, Path=AdornedElement.(Validation.Errors)[0].ErrorContent}">
<TextBlock Text="!" VerticalAlignment="center" HorizontalAlignment="center" FontWeight="Bold" FontSize="8" Foreground="white" />
</Border>
<AdornedElementPlaceholder Name="customAdorner" VerticalAlignment="Center" >
<Border BorderBrush="red" BorderThickness="1" />
</AdornedElementPlaceholder>
</DockPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBoxBase}">
<Border x:Name="Border"
BorderThickness="1"
CornerRadius="3"
Padding="0">
<Border.BorderBrush>
<LinearGradientBrush StartPoint="0,0" EndPoint="1,1">
<GradientStop Color="#AAAAA1" Offset="0" />
<GradientStop Color="#AAAAA1" Offset=".2" />
</LinearGradientBrush>
</Border.BorderBrush>
<ScrollViewer x:Name="PART_ContentHost" Margin="0">
<ScrollViewer.Background>
<LinearGradientBrush StartPoint="0,0" EndPoint="0,1">
<GradientStop Offset="0" Color="#ededed"/>
<GradientStop Offset=".91" Color="White"/>
</LinearGradientBrush>
</ScrollViewer.Background>
</ScrollViewer>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Setter TargetName="Border" Property="Background" Value="#EEEEEE"/>
<Setter TargetName="Border" Property="BorderBrush" Value="#EEEEEE"/>
<Setter Property="Foreground" Value="#888888"/>
</Trigger>
<Trigger Property="Validation.HasError" Value="true">
<Setter Property="Margin" Value="0 0 15 0" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>

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>

WPF Change size of menuitem

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.

How would I add a tooltip on resizing RadGridView column

I can't seem to find any decent way to add a ToolTip to display the column width in pixels for a Telerik RadGridView control. Anyone have any ideas on how to go about doing this?

I would try adding a Style for all Columns that binds the ToolTip property to the column's ActualWidth property
<Style TargetType="{x:Type telerik:GridViewBoundColumnBase}">
<Setter Property="ToolTip" Value="{Binding ActualWidth, RelativeSource={RelativeSource Self}}" />
</Style>

How to select default button in wpf dialog?

I am creating a WPF dialog. It is like our normal messagebox with ok and cancel button. How to create such a dialog so that the Ok button is selected when the dialog is opened?

To set a Window's Default button
Set your default button's IsDefault property to true.
Note that you can also set a Window's Cancel button by setting a button's IsCancel property to true.
To set the Selected (focused) button in a Window
If you want to select a particular button then use the Focus method like this:
yourButton.Focus();
You might do this when a Window loads (in the Window_Loaded event).
To select a particular button when your Window opens make sure its IsTabStop property is set to true and ensure its TabIndex property is lower than any other control on the Window.

just create a new button template and change the look and feel for the IsDefault=Tue state.
I just created a style and modified the state.

How about IsDefault?
<Button Command="{Binding MyButtonCommand}"
Content="My Button Text"
IsDefault="True"/>
