How can i make a combobox edges rounded..?.I have tried in blend,but no success till now..Any input will be highly helpfull
You need to create a custom Style in XAML for your ComboBox in which the outer container is a border with rounded corners. In this particular example, it's a default style that will be blanket applied throughout your application. The content of the control and ContentPresenter must still be declared within the Border.
<Style TargetType="{x:Type ComboBox}">
...
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ComboBox}">
<Border CornerRadius="5">
...
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

I am very new to WPF. I've familiarized myself with ControlTemplate, ContentPresenter, and some other pieces, but I am struggling to create a button with rounded corners as defined from Window.Resources (or potentially a separate style file).
Anyways, when I add this to a <Button/> tag, I get a button with rounded corners:
<Button.Resources>
<Style TargetType="Border">
<Setter Property="CornerRadius" Value="5"/>
</Style>
</Button.Resources>
However, when I try to include it up in the Window.Resources the button will not apply the border style:
<ControlTemplate x:Key="roundbutton" TargetType="Button">
<Grid>
<Rectangle Fill="{TemplateBinding Background}" Stroke="{TemplateBinding Foreground}"/>
<Border CornerRadius="5"/>
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Grid>
</ControlTemplate>
This doesn't look right to me, but I guess I don't know where to add the specification of CornerRadius such that it will apply to the button. I did see this post, How to create/make rounded corner buttons in WPF? but it's a little over my head. I just want to round all the buttons in my application!
The Border in your ControlTemplate is not visible, because you have neither set its Background, nor its BorderBrush.
You could have something like shown below. Note however that with a simple ControlTemplate like this a Button loses all the visualizations of its states, like focused, mouse-over, pressed etc.
<ControlTemplate x:Key="roundbutton" TargetType="Button">
<Border Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
CornerRadius="5">
<ContentPresenter/>
</Border>
</ControlTemplate>
You may instead just declare a default Button Style (i.e. a Style resource without x:Key) that applies your original Border Style like this:
<Style TargetType="Button">
<Style.Resources>
<Style TargetType="Border">
<Setter Property="CornerRadius" Value="5"/>
</Style>
</Style.Resources>
</Style>
We have a specific look and feel to buttons in our application and these are defined in a named style for ButtonBase which also happens to be the default style for Button, ToggleButton and RepeatButton.
We also have ToolbarButtons which are derived from ButtonBase and include extra properties such as Text and Icon. These are used to place a specific text and an icon on a ToolbarButton.
The theme for ToolbarButtons is defined as follows in Themes/generic.xaml:
<Style TargetType="{x:Type c:ToolbarButton}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type c:ToolbarButton}">
<Button Command="{TemplateBinding Property=Command}">
.. controls to place text and icon etc ..
</Button>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
As you can see I'm using a Button control within a control based on ButtonBase and binding the Command to the Command on the contained Button. This hack makes sure that I can override the style of the 'Button' used in the Toolbar by defining the Button default style.
It all seems to work quite well, but it does not feel right using a Button inside a Button. I'm still wondering if I'm doing the right thing. Any ideas?
Your approach is good but you don't have to use a second button in your template, but a ContentPresenter. Use it every time your redefine the template of a ContentControl (a button for example). The BasedOn attribute is useful to override the specific button style.
It looks like this :
<Style TargetType="{x:Type c:ToolbarButton}" BasedOn="{StaticResource {x:Type ButtonBase}}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type local:ToolbarButton}">
<StackPanel>
<!-- Image -->
<Image Source="{TemplateBinding Image}"/>
<!-- Content -->
<ContentPresenter Content="{TemplateBinding Content}"/>
</StackPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
You will find the same mechanism with the templates of the ItemsControl (ListBox, ListView, etc) with the ItemsPresenter.
UPDATE:
To take your comment in account, maybe you should override a ContentControl to apply your specific chrome to it:
public class ButtonContentControl : ContentControl { }
<Style TargetType="{x:Type local:ButtonContentControl}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type local:ButtonContentControl}">
<!-- Specific chrome -->
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Then you can use it inside the templates of your ButtonBase and your ToolbarButton :
<
Style TargetType="{x:Type ButtonBase}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type c:ToolbarButton}">
<ButtonContentControl>
<!-- ContentPresenter or something else -->
</ButtonContentControl>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<Style TargetType="{x:Type c:ToolbarButton}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type c:ToolbarButton}">
<ButtonContentControl>
.. controls to place text and icon etc ..
</ButtonContentControl>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
I'm trying to write a reusable Template for a WPF ItemContainerStyle.
This Template changes the way the TabControl's Item looks.
This template is meant to be used in several places in the application.
In each place it is used I want to be able to pass different parameters to it.
For example: to change the Margin of the Border of the Item:
<Style x:Key="TabItemStyle1" TargetType="{x:Type TabItem}">
<Setter Property="Margin" Value="10,0"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Grid SnapsToDevicePixels="true">
<Border x:Name="Bd" Width="80"
Background="Gray"
Margin="{TemplateBinding Margin}">
<ContentPresenter x:Name="Content"
ContentSource="Header" />
</Border>
</Grid>
<ControlTemplate.Triggers>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
...
<TabControl ItemContainerStyle="{DynamicResource TabItemStyle1}">
In the place where the style is used I Would like to Write something like:
ItemContainerStyle="{DynamicResource TabItemStyle1 Margin='5,0'}"
or
<TabControl Margin="78,51,167,90" ItemContainerStyle="{DynamicResource TabItemStyle1}"
ItemContainerStyle.Margin="5,0">
The motivation is to use this template in different places with different Margins.
Is there a way to do this ?
Thank you
You can do it with attached properties. I wrote a blog post explaining how to do it:
http://www.thomaslevesque.com/2011/10/01/wpf-creating-parameterized-styles-with-attached-properties/
Another option is to use DynamicResource, and redefine the resource in derived styles
OK, I've found a way to do this with dave's help.
The Solution is to create a derived template and set the properties in it.
This way the original template can be reused.
<Style x:Key="TabItemStyle2" TargetType="{x:Type TabItem}"
BasedOn="{StaticResource TabItemStyle1}">
<Style.Setters>
<Setter Property="Margin" Value="40,0"></Setter>
</Style.Setters>
</Style>
And set the TabControl's ItemContainerStyle to the derived style:
<TabControl ItemContainerStyle="{DynamicResource TabItemStyle2}">
In my case I had to change some parameters deep in the applied template (so I couldn't use just a setter).
And I didn't want to code some classes that traverse the visual tree or register an attached property to do the changes.
However, it is possible to define resources within the base style and override these values in the derived definitions. So, with the original example this would look like this:
<Style x:Key="AbsTabItemStyle" TargetType="{x:Type TabItem}">
<!-- Override these default values in derived style definitions -->
<Style.Resources>
<s:Double x:Key="GridBorderMargin">10</s:Double>
<Color x:Key="GridBorderColor">Grey</Color>
</Style.Resources>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Grid SnapsToDevicePixels="true">
<Border x:Name="Bd"
Width="80"
Background="{DynamicResouces GridBorderColor}"
Margin="{DynamicResouces GridBorderMargin}"
>
<ContentPresenter x:Name="Content"
ContentSource="Header" />
</Border>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<Style x:Key="BigMarginTabItemStyle" TargetType="{x:Type TabItem}" BasedOn="{StaticResource AbsTabItemStyle}">
<!-- Set different values in this derived style definition -->
<Style.Resources>
<s:Double x:Key="GridBorderMargin">20</s:Double>
</Style.Resources>
</Style>
<Style x:Key="RedTabItemStyle" TargetType="{x:Type TabItem}" BasedOn="{StaticResource AbsTabItemStyle}">
<!-- Set different values in this derived style definition -->
<Style.Resources>
<c:Color x:Key="GridBorderColor">Red</Color>
</Style.Resources>
</Style>
A way of solving it is by adding a Margin property to the objects/ViewModels you want to display and (data)bind to that value in the template.
As far as I know there is no support of parameterized styles/templates.
I want to use the ExtendedWPFToolkits's ColorPicker but with a custom ButtonStyle.
I can create a new look overriding the Template property of the item but the original templates click event is missing.
I want to keep it, but how?
<Controls:ColorPicker >
<Controls:ColorPicker.ButtonStyle>
<Style TargetType="{x:Type ToggleButton}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Button Content="ColorPicker"></Button>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Controls:ColorPicker.ButtonStyle>
</Controls:ColorPicker>
What you have is not valid. You are putting a Button in the ControlTemplate of a ToggleButton, so basically a button in a button.
You'd need to do something like:
<Controls:ColorPicker >
<Controls:ColorPicker.ButtonStyle>
<Style TargetType="{x:Type ToggleButton}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Border Background="Transparent">
<TextBlock Text="ColorPicker" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Controls:ColorPicker.ButtonStyle>
</Controls:ColorPicker>
I added a transparent Border so the button will be able to receive mouse events for areas not covered by the text.
I have a ListView...and I am overriding the template of listview item to add a border to it.
But, when I do that - while selecting an item in listview ...the background is not getting changed to blue(as it do normally).
Do I need to add TemplateBinding for background color ? Please help me.
<ListView.Resources>
<Style TargetType="{x:Type ListViewItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType='{x:Type ListViewItem}'>
<Border DataContext="{Binding Item.Type}" Style="{StaticResource ValidationResultBorderStyle}" HorizontalAlignment="Left"
<GridViewRowPresenter />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ListView.Resources>
When we override the Template of any item containers, we should maintain their behaviors from their default template... To do that we must maintain their content presenters and triggers etc...
