WPF Change size of menuitem

WPF Change size of menuitem - c#

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 used above code for creating button but it will not giving expected result. look like this.
Any help will be appreciated.

You can use borders inside a button template with a blur-effect to achive the requested result:
<Button Content="English" Width="100" Height="50">
<Button.Style>
<Style TargetType="{x:Type Button}" >
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ButtonBase}">
<Border CornerRadius="5" Background="{TemplateBinding Background}" Name="button" Width="100">
<Grid>
<Border BorderThickness="1,0,1,1" BorderBrush="Black" CornerRadius="{Binding ElementName=button, Path=CornerRadius}">
<Border.Effect>
<BlurEffect Radius="2" KernelType="Gaussian"/>
</Border.Effect>
</Border>
<Border BorderThickness="0,1,0,0" BorderBrush="White" Margin="2" Opacity="0.7" CornerRadius="{Binding ElementName=button, Path=CornerRadius}">
<Border.Effect>
<BlurEffect Radius="2" KernelType="Gaussian"/>
</Border.Effect>
</Border>
<ContentPresenter TextBlock.FontSize="{TemplateBinding FontSize}" TextBlock.FontFamily="{TemplateBinding FontFamily}" TextBlock.Foreground="{TemplateBinding Foreground}" VerticalAlignment="Center" HorizontalAlignment="Center" Content="{TemplateBinding Content}"></ContentPresenter>
</Grid>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Setter Property="Background" Value="#002060" />
<Setter Property="Foreground" Value="White" />
<Setter Property="FontSize" Value="20" />
<Setter Property="FontFamily" Value="Consolas" />
</Style>
</Button.Style>

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

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>

SnapsToDevicePixels option

I am trying to style some tabs but I ran into this issue where the color of the border changes as I resize window. First of all, I used this http://blogs.intuidev.com/post/2010/01/25/TabControlStyling_PartOne.aspx to style the tabs if you're wondering about the code.
Also, here is the pic of what's wrong.
EDIT:
<Color x:Key="BorderColor_Base">#888</Color>
<Color x:Key="TabControl_BackgroundColor_Base">#CCC</Color>
<SolidColorBrush x:Key="TabControl_BackgroundBrush_Base"
Color="{StaticResource TabControl_BackgroundColor_Base}"/>
<LinearGradientBrush x:Key="TabItemPanel_BackgroundBrush"
StartPoint="0,0" EndPoint="0,1">
<LinearGradientBrush.GradientStops>
<GradientStop Offset="0.98" Color="Transparent"/>
<GradientStop Offset="0.99"
Color="{StaticResource BorderColor_Base}"/>
</LinearGradientBrush.GradientStops>
</LinearGradientBrush>
<SolidColorBrush x:Key="TabItem_BorderBrush_Selected"
Color="{StaticResource BorderColor_Base}" />
<Style TargetType="{x:Type TabControl}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="TabControl">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="1*"/>
<RowDefinition Height="10*"/>
</Grid.RowDefinitions>
<Border Background="{StaticResource TabItemPanel_BackgroundBrush}"
Padding="{StaticResource TabItemPanel_Padding}">
<TabPanel Grid.Row="0" IsItemsHost="True"/>
</Border>
<ContentPresenter Grid.Row="1" ContentSource="SelectedContent"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<Style TargetType="{x:Type TabItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Grid>
<Border Name="Border"
Background="{StaticResource TabControl_BackgroundBrush_Base}"
BorderBrush="{StaticResource TabItem_BorderBrush_Selected}"
Margin="{StaticResource TabItemMargin_Selected}"
BorderThickness="2,1,1,1">
<!-- This is where the Content of the TabItem will be rendered. -->
<Viewbox>
<TextBlock x:Name="Header">
<ContentPresenter x:Name="ContentSite"
ContentSource="Header"
Margin="7,2,12,2"
RecognizesAccessKey="True"/>
</TextBlock>
</Viewbox>
</Border>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="False">
<Setter TargetName="Border" Property="Margin" Value="{StaticResource TabItemMargin_Base}" />
<Setter Property="Panel.ZIndex" Value="90" />
</Trigger>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Panel.ZIndex" Value="100" />
<Setter TargetName="Border" Property="BorderThickness" Value="2,1,1,0" />
<Setter TargetName="Border" Property="Background" Value="White" />
</Trigger>
<Trigger Property="IsEnabled" Value="False">
<Setter TargetName="Header" Property="Background" Value="#CCC" />
<Setter TargetName="Header" Property="Foreground" Value="#888" />
<Setter Property="Panel.ZIndex" Value="80" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

The issue is with this brush:
<LinearGradientBrush x:Key="TabItemPanel_BackgroundBrush" StartPoint="0,0" EndPoint="0,1">
<LinearGradientBrush.GradientStops>
<GradientStop Offset="0.98" Color="Transparent" />
<GradientStop Offset="0.99" Color="{StaticResource BorderColor_Base}" />
</LinearGradientBrush.GradientStops>
</LinearGradientBrush>
You are using a gradient from transparent to #888 as your background, so you are seeing one of the colors "in between" transparent and #888. Instead, you can use a Transparent background and border of #888, like so:
<Style TargetType="{x:Type TabControl}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="TabControl">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="1*" />
<RowDefinition Height="10*" />
</Grid.RowDefinitions>
<Border Grid.Row="0" Background="Transparent" BorderBrush="#888" BorderThickness="0,0,0,1" Padding="{StaticResource TabItemPanel_Padding}"
SnapsToDevicePixels="True" />
<TabPanel Grid.Row="0" IsItemsHost="True" />
<ContentPresenter Grid.Row="1" ContentSource="SelectedContent" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
You may need to tweak the Margin of the Border and/or the TabPanel to ensure they line up correctly though.

Labas!
Try to increase line's height, for instance set it to 5 or 10 pixels. If color is wrong again it means that you wrong styled TabControl.

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
