I have a ListView with rows containing TextBlock and ComboBox.
I want to create keyboard TAB navigation that:
on TAB - focus switches between combo-box-es
rows (as a controls) are never selected
But by default ListView on TAB 1st select whole row and then focus on combo-box.
--------------
Select value:
[combo-box-1]
--------------
Select value:
[combo-box-2]
--------------
Select value:
[combo-box-3]
--------------
The default TabNavigation of ListView is Once, this means the container and all of its child elements as a whole receive focus only once, so you need to change it as Cycle or Local. In addition, if you don't want to select the items by pressing the Tab key, you need to set IsTabStop to false for each item, in this case, items won't be included in tab navigation.
xaml:
<ListView x:Name="MyListView" TabNavigation="Cycle" ...>
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="IsTabStop" Value="False"/>
</Style>
</ListView.ItemContainerStyle>
......
</ListView>

The default colors for these controls seems to be similar to the Windows theme colors. How do you change the hover, selected, selected hover and pressed colors (code or XAML)? The following isn't working for the ListView:
<ListView>
<ListViewItemPresenter
PointerOverBackground="#99CEEA"
SelectedPressedBackground="#72BFE9"
SelectedBackground="#72BFE9"
SelectedPointerOverBackground="#99CEEA"
/>
In your VS/Blend Designer, right click on your ListView and select
Edit Additional Templates > Edit Generated Item Container
(ItemContainerStyle) > Edit a Copy...
In the popup window above, if you want this style to be applied to all your ListViewItem, select Apply to all otherwise just give it a name.
I'd recommend to create a new Resource dictionary for storing all ListView related styling. To do so, just hit the New... button and give the resource dictionary a name (e.g. ListViewStyles.xaml).
Finally, hit the OK button and you now have a fully generated style.
In the style's ControlTemplate, you can locate the ListViewItemPresenter control and update its colors accordingly.
The ListViewItemPresenter was in the wrong place in the XAML. Change this:
<ListView>
<ListViewItemPresenter
PointerOverBackground="#99CEEA"
SelectedPressedBackground="#72BFE9"
SelectedBackground="#72BFE9"
SelectedPointerOverBackground="#99CEEA"
/>
</ListView>
to this:
<ListView>
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListViewItem">
<ListViewItemPresenter
PointerOverBackground="#99CEEA"
SelectedPressedBackground="#72BFE9"
SelectedBackground="#72BFE9"
SelectedPointerOverBackground="#99CEEA" />
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ListView.ItemContainerStyle>

When using a listitem in a w8 app, how can I determine what gives the hover and click styles?
My listview looks like this:
<ListView x:Name="itemsListView"
TabIndex="1"
Visibility="Visible"
Padding="10,0,0,0" Foreground="Black"
ItemsSource="{Binding Nodes.Nodes}"
behaviors:ListViewItemClickedToAction.Action="{Binding SelectNodeAction}"
IsItemClickEnabled="True" FontFamily="Global User Interface"
>
<ListView.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Name}" />
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
When I hover using the mouse I get white letters and an almost white background.
I have tried reusing parts of the adventureworks shopper app, so there are styles from there copied. However, I can't understand what is applied to the ListView items.
You maybe already new this but if you check this screenshot you can see how you easily in VS2012 can create a copy of a built in style. When you press the "Edit a copy ..." a dialog will appear where you can choose where in the Project you want the style to be placed.
You can inherit styles. The inheritence of styles work in the following way:
<Style x:Name="BasicStyle" TargetType="Button">
<Setter Property="Background" Value="Green" />
</Style>
<Style x:Name="ButtonStyle" TargetType="Button" BasedOn="{StaticResource BasicStyle}">
<Setter Property="Foreground" Value="Red" />
</Style>
You can do inheritence in several steps so Another button style can inherit the "ButtonStyle".
You can thus make a style that only contains the Template property if you want to seperate it or reuse the behaviour and look of your style. But you cannot split the Visual State Manager into several styles since if you inherit a style which sets the template property and then if you want to change the Hover state of that style you need to make a copy of the whole template and only change that part in the code.
I Think this would be a nice improvement by MS if you could make a style which only contains the pressed state and then Another style which only contains the hover effect and so on.
I hope this answers your questions :) I would love to answer more questions regarding XAML if you have any!
What is the correct way to apply styles on elements with a condition on their parent element's type, i. e. only if they are children of certain other elements?
In my case, I want to apply some exact button width and height, but only if those buttons are direct children of a stackpanel. Additionally, a second style should be applied to images within those buttons (glyphs).
How do I define a button style that only affects buttons on a stackpanel, but not those buttons placed directly on a grid?
Is it possible to add additional conditions such as only stackpanels with orientation="horizontal"?
Can I define "tree conditions" like only images on buttons on [horizontal] stackpanels?
As 90% of all buttons in my application are those on the stackpanels, so far I've applied the style to all buttons and images and overrode it where necessary. But this isn't the best solution, is it?
Preferably, the solution would deal with all the conditions in the style definition, so I won't have to explicitly assign that style to every single one of my stackpanels.
<StackPanel>
<StackPanel.Resources>
<Style x:Key="Rectangle1" TargetType="Rectangle">
<Setter Property="Stroke" Value="Black" />
<Setter Property="Fill" Value="White" />
</Style>
</StackPanel.Resources>
<UniformGrid Columns="10">
<UniformGrid.Resources>
<Style TargetType="Rectangle" BasedOn="{StaticResource Rectangle1}">
<Setter Property="Fill" Value="Red" />
</Style>
</UniformGrid.Resources>
</UniformGrid>
</StackPanel>
I have a question
I've created new win8 metro app and I don't get from where it is taking styles.
I've change in App.xaml name of styles file. My Style.xaml looks like this
<!-- Page layout roots typically use entrance animations and a theme-appropriate background color -->
<Style x:Key="LayoutRootStyle" TargetType="Panel">
<Setter Property="Background" Value="White"/>
<Setter Property="ChildrenTransitions">
<Setter.Value>
<TransitionCollection>
<EntranceThemeTransition/>
</TransitionCollection>
</Setter.Value>
</Setter>
</Style>
But still I got gold letters, my buttons change white when I'm hover it. Same like with default StandardStyles.xaml
What am I doing wrong ? Or it works just fine ?
The style you show would only affect the the panel that uses that style. If you put a button inside a the panel, the panel's style does not cascade to the button. The button has its own style, as you correctly deduced from standardstyles.xaml, that controls its appearance. If you want to change the style of the button, you need to create a new style or update the current style.
The problem is you gave your style a key using the x:Key attribute. Once a style has a key it will only be applied to controls that implicitly use that named style. If you remove the key, the style should be applied to all controls that match TargetType (in this case Panel).
I want to disable Tile effect that is some kind of pushed effect and hover background color effect of ListView control, how can i do that?
Thanks
After some googling I found that the highlighting happens in the ListViewItemPresenter, which turns out to be pretty hidden. It's located inside the ControlTemplate of an ListViewItem, which is the ItemContainer for the ListView. The simplest way I've found to disable the effect is to simply override this ControlTemplate:
<ListView>
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<ContentPresenter/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ListView.ItemContainerStyle>
<TextBlock Text="List Item" />
...
<TextBlock Text="List Item" />

Look at this question:
Disable cross-slide selection for a listview
You can also make changes to the template to remove any visual states and adornments - go to the designer and right click your ListView/Edit Additional Templates/Edit Generated Item Container (ItemContainerStyle)/Edit a Copy... - that will extract the template you can modify using your preferred method.
