here is whats getting on my nerve:
My job si to restyle application, so i didn’t wrote it, i have to slightly change the code(.cs or .xaml). Problem lies within avalonDock…i cant remove borders from panels, or change its color.
This is part of code, where dockingManager parts are defined(lets call it MainView.xaml)
<ad:DockingManager Name="dockingManager" >
<ad:ResizingPanel Orientation="Horizontal">
<ad:DockablePane ad:ResizingPanel.ResizeWidth="50" Name="navigatorHostCtrlPane" >
<ad:DockableContent Name="navigatorHostCtrl" Title="{StaticResource Navi}" IsCloseable="False" Background="Transparent"/>
</ad:DockablePane>
<ad:ResizingPanel Orientation="Vertical" >
<ad:DockablePane Name="mainPane" >
<ad:DockableContent x:Name="mainHostCtrl" Title="{StaticResource Sc}" AllowDrop="False" IsCloseable="False" ClipToBounds="False" Background="White"/>
</ad:DockablePane>
<ad:DockablePane ad:ResizingPanel.ResizeHeight="250" >
<ad:DockableContent Name="dataHostCtrl" Title="{StaticResource Dt}" IsCloseable="False" Background="White"/>
</ad:DockablePane>
</ad:ResizingPanel>
</ad:ResizingPanel>
</ad:DockingManager>
And this is where parts are set in .cs file(MainView.xaml.cs) like this:
BindRegionToGui(regionManager, RegionNames.NavigatorRegion, navigatorHostCtrl);
And BindRegionToGui():
private static void BindRegionToGui(IRegionManager regionManager, string regionName, UIElement content)
{
var reg = (AvalonDockRegion)regionManager.Regions[regionName];
reg.Bind(content);
}
I cant change style of outer border even in element by setting BorderThickness = “1“, or in style definition:
<Style x:Key="{x:Type ad:DockablePane}" TargetType="{x:Type ad:DockablePane}">
<Setter Property="Background" Value="Transparent"/>
<Setter Property=“BorderThickness“ Value=“0“/>
</Style>
I can alter whole dockingPanes by setting style like this(after some example):
<Style TargetType="{x:Type ad:DockablePane}">
…
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ad:DockablePane}">
<Border
Background=….
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
But with this – the content won’t show up. I assume, that content.template overrides it, but i dont know how i can put application’s defined panels into it.
Sorry if this is stupid question but i am really beginner in xaml / c# so i’m in kind of a bad situation.
I restyled AvalonDock in pretty dumb way. I've downloaded source code from http://avalondock.codeplex.com/SourceControl/list/changesets, changed generic.xaml and rebuild whole library.

I've this code in C# to create a button as a child of a StackPanel:
`
Button myButton = new Button();
//All button stuff (Background, text...).
myStackPanel.Children.add(myButton);
`
But, as every button, it highlights every time the mouse is over or when I click it. Is there any way to change that in an easy code (I'm still new to C#) can remove that highlight.
I don't know how to do this. I haven't seen anything explaining this and the only codes I could find were in XAML, and I didn't understand them so couldn't translate them to C#.
The problem is all the code I find is about retemplating the XAML code. What I need is to do what I mentioned in C#, as the control is created from scratch in C#.
I took a look at a few of the answers for this and didn't see any I liked much.
WPF controls are lookless, meaning they have fixed behaviour but not specific look to them. You can re template a wpf control to pretty much anything you can describe in xaml. Many wpf controls have quite complicated templates.
Here's one way to template a button as described.
I've put this style in my window's resources. Usually such styles are in resource dictionaries which are merged in app.xaml.
<Window.Resources>
<Style x:Key="NoMouseOverButtonStyle" TargetType="{x:Type Button}">
<Setter Property="SnapsToDevicePixels" Value="true" />
<Setter Property="OverridesDefaultStyle" Value="true" />
<Setter Property="BorderBrush" Value="LightGray"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="Background" Value="Transparent"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="Border"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}"
Background="{TemplateBinding Background}" >
<ContentPresenter Margin="2"
HorizontalAlignment="Center"
VerticalAlignment="Center"
RecognizesAccessKey="True" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
<Grid>
<Button Style="{StaticResource NoMouseOverButtonStyle}"
Content="This is my Button"
Click="Button_Click"
HorizontalAlignment="Left"
VerticalAlignment="Top"
/>
</Grid>
</Window>
The button references the style as a resource.
That style sets some defaults so the button has a border you can see but over ride.
The contentpresenter is critical because this is where whatever you make content of your button will appear.
If I set an actual value on a button then that will over ride the style.
Hence
<Button Style="{StaticResource NoMouseOverButtonStyle}"
Content="This is my Button"
Click="Button_Click"
HorizontalAlignment="Left"
VerticalAlignment="Top"
BorderBrush="Red"
/>
Gives me a red border on my button.
A lightgray border is rather simpler than a button has by default.
You could reproduce that. Maybe that'd be an interesting learning exercise.
Lookup the button template on msdn.
Google: "wpf button template msdn"
Take a look at that. Brace yourself - it is complicated.
See the button border brush is hard coded in the template?
Change the style above so it does the same.
Clue:
<Setter.Value>
From here I learned how to change the styling of dotted lines around focused button. I would like to apply the same thing on all focus-able elements of the current WPF application (or if not possible current page) in one place ( not doing separately for focus-able buttons, textboxes etc)
PS. Preferably in code behind
Define this Style in your App.Xaml .
<Application.Resources>
<Style x:Key="StyleFocusDefault" TargetType="{x:Type Control}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Control}">
<Grid>
<Rectangle StrokeThickness="2" Stroke="Black" StrokeDashArray="2"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Application.Resources>
And then you can apply like : < ... FocusVisualStyle="{DynamicResource StyleFocusDefault}" .../>
This will change FocusVisualStyle for all Controls who have FocusVisualStyle property. You can further experiment with this appaorach for various controls.
I need to display a number in a square, centered horizontally and vertically.
When I tried to use a label for that purpose, it seemed like it ignored the centering completely. So I decided to use a grid and display a label on the grid as that centers perfectly.
I need to use a template as there's several themes available. From what I've found on the internet, I thought this ( ignoring the centering for now )
<ControlTemplate x:Key="ClockTemplate">
<Grid>
<Grid.Style>
<Style TargetType="Grid">
<Setter Property="Background" Value="White"/>
</Style>
</Grid.Style>
<Label>
<Label.Style>
<Style TargetType="Label">
<Setter Property="Foreground" Value="#376092"/>
</Style>
</Label.Style>
<ContentPresenter/>
</Label>
</Grid>
</ControlTemplate>
would be correct. Using it as follows:
<ContentControl Content="20" Height="64" Width="64" Template="{DynamicResource ClockTemplate}"/>
the content is not displayed tho, what am I doing wrong? Also, is there a better way to achieve my goal?
As per my understanding this is not the correct approach. Instead of creating ControlTemplate you have to write a Style for your control like below, also use StaticResource binding if possible. It is faster than Dynamic binding. Please not that, I have not mentioned the Label size inside the ControlTemplate. Please do it based on your needs
<Style x:Key="ContentControlStyle"
TargetType="ContentControl">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ContentControl">
<Grid Background="White">
<Label Foreground="#376092"
Width="200"
Height="100" Content="{TemplateBinding Content}">
</Label>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
bind your ContentControl with the newly created Style like below
<ContentControl Style="{StaticResource ContentControlStyle} ">
If your requirement is only to set some value in ContentControl, use Label instead and change the Style of the Label. Because ContentControl is heavy
I have PortItem which derived from ContentControl, TextedStackPanel derived from StackPanel which contains PortItems. And in MainWindow i have 2 StackPanels which contains TextedStackPanels . In PortItem i have overridden MouseLeftButtonDown method. But when i do this on this method isn't fired. I searched here in the forum, and found that Background property of Grid/StackPanel must be set to Transparent. I applied this, but there is no changes. What to do ?
EDIT 1
I use partial classes. I have 2 classes: PortItem.cs and PortItem.cs.xaml. I modifiy any visual changes in this XAML file.
EDIT 2
Also any mouse events aren't fired. Triggers which i use IsMouseOver are also dont work when i keep mouse on PortItem
XAML
<ContentControl x:Class="**.PortItem"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:UI="clr-namespace:**.UIData" Width="17" Height="17" Margin="3" SnapsToDevicePixels="True" >
<Grid Background="Transparent" Name="mainGrid">
<!-- transparent extra space makes connector easier to hit -->
<Rectangle Fill="Transparent" Margin="-2"/>
<Border BorderBrush="Green" x:Name="border" BorderThickness="2">
<Border.Style>
<Style>
<Style.Triggers>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=Grid}, Path=IsMouseOver}" Value="True">
<Setter Property="Border.BorderBrush" Value="Blue"/>
</DataTrigger>
<DataTrigger Binding="{Binding IsSelected}" Value="True">
<Setter Property="Border.BorderBrush" Value="Blue"/>
</DataTrigger>
<!--<DataTrigger Binding="{Binding ContactPort}" Value="{x:Null}">
<Setter TargetName="border" Property="Border.BorderBrush" Value="Green"/>
</DataTrigger>-->
</Style.Triggers>
</Style>
</Border.Style>
<Image Source="/**;component/Resources/1337238611_port.png">
</Image>
</Border>
</Grid>
Make sure that you haven't set 'IsHitTestVisible' to false on your PortItem. Also, make sure no other controls are on top of it. If they are, set their 'IsHitTestVisible' property to false and then your PortItem control will get the mouse right click event. To make sure nothing is on top, declare your put your PortItem as the last thing added to your TextedStackPanel. To double check that nothing else is on top, change the background color of other controls to something really noticeable (just for testing) to see if anything is covering your PortItem control. Also, change the color on your PortItem control to verify that it is really where you think it is. Then once you get it all working, change the colors back to their original colors.
If you could give us a code sample of your XAML, that might help. If you're adding the PortItems dynamically in code behind, supply that code too.
Edit: in light of the changes you've made to your code, try to add ClipToBounds="False" to the top of your user control declaration.
<ContentControl x:Class="**.PortItem" ClipToBounds="False"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:UI="clr-namespace:**.UIData" Width="17" Height="17" Margin="3" SnapsToDevicePixels="True" >
Have you created a template for your PortItem? I created the follow class to replicate your PortItem and break point on the base.OnMouseButtonDown line and it fires, I think the reason your method is not executing is because there is no visual element for the mouse to actually interact with, try adding the style below to your app and you should see the method fire properly.
public class PortItem: ContentControl
{
protected override void OnMouseLeftButtonDown(MouseButtonEventArgs e)
{
base.OnMouseLeftButtonDown(e);
}
}
then in XAML I created a style to give it something to render.
<local:PortItem Margin="44,36,156,95">
<local:PortItem.Style>
<Style TargetType="{x:Type local:PortItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type local:PortItem}">
<Border Background="Transparent">
<ContentPresenter Content="{TemplateBinding Content}"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</local:PortItem.Style>
</local:PortItem>
The background being Transparent that you mention you can see in the border control, if you leave the background out you are correct, the event never fires.
I have an Image control on my WPF Form. How can I create a border around it during runtime?
Here's my XAML code:
<Image Margin="2.5"
Grid.Column="1" Grid.Row="0"
x:Name="Behemoth" Source="Images/Hero/Behemoth.gif" Stretch="Fill"
MouseEnter="HeroMouseEnter"
MouseLeave="HeroMouseLeave"
MouseDown="HeroMouseClick" />
Also, I want to know how to remove the border.
Maybe if I state my problem better there is an even better solution available.
I have many Images, and when a user says: "Hey, just show me the woman out of all the picture." I want a way to sort of highlight or draw the users attention to whatever images I need them to see. I was thinking about adding a border, but maybe that's too much work for something that can be solved easier.
Any help?
Although it's visually very different from a border, you could use an outter glow to signify the importance of the image. Then, you don't have to change the parent of the image.
Alternatively, you could use a custom Adorner to place a border around the image. Good info on Adorners can be found on msdn.
There's no straightforward way to do it, because the Border is a container, so you would have to remove the Image from its parent, put the Border instead, and put the Image back in the Border...
Another option would be to use templates :
<Window.Resources>
<ControlTemplate x:Key="imageWithBorder" TargetType="{x:Type Image}">
<Border BorderBrush="Red" BorderThickness="2">
<Image Source="{TemplateBinding Source}" />
</Border>
</ControlTemplate>
</Window.Resources>
...
<Image Name="image1" Source="foo.png"/>
When you want to put the border around the image, just assign the template to the image :
image1.Template = this.FindResource("imageWithBorder") as ControlTemplate;
For your stated needs, I suggest you use a ListBox with a custom ItemContainerStyle - one that always has a border but only makes it visible if the item is selected.
Here's the basic idea:
<ListBox ItemsSource="{Binding MyImageObjects}">
<ListBox.ItemContainerStyle>
<Style TargetType="{x:Type ListBoxItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListBoxItem}">
<Border x:Name="border">
<ContentPresenter />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="ListBoxItem.IsSelected" Value="True">
<Setter ElementName="border" Property="BorderBrush" Value="Blue" />
<Setter ElementName="border" Property="BorderThickness" Value="2" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ListBox.ItemContainerStyle>
</ListBox>
