I have a listbox in WPF, and when they select an item, it shows an ugly colors Can I make al开发者_如何学Gol the items non-selectable?
If you don't need selection, use an ItemsControl
rather than a ListBox
Add Focusable property as false in ListBoxItem style:
<Style x:Key="{x:Type ListBoxItem}" TargetType="{x:Type ListBoxItem}">
<!-- Possibly other setters -->
<Setter Property="Focusable" Value="False" />
</Style>
Please use this inside your listbox. I found this very elegant solution
<ListBox ItemsSource="{Binding YourCollection}">
<ListBox.ItemContainerStyle>
<Style TargetType="{x:Type ListBoxItem}">
<Setter Property="Focusable" Value="False"/>
</Style>
</ListBox.ItemContainerStyle>
</ListBox>
If you dont want them selectable then you probably dont want a listview. But if this is what you really need then you can do it with a style:
<Page
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Page.Resources>
<Style x:Key="{x:Type ListBoxItem}" TargetType="{x:Type ListBoxItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListBoxItem}">
<Border
Name="Border"
Padding="2"
SnapsToDevicePixels="true">
<ContentPresenter />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="true">
<Setter TargetName="Border" Property="Background" Value="#DDDDDD"/>
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Foreground" Value="#888888"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Page.Resources>
<Grid>
<ListBox>
<ListBoxItem>One</ListBoxItem>
<ListBoxItem>Two</ListBoxItem>
<ListBoxItem>Three</ListBoxItem>
</ListBox>
</Grid>
</Page>
Look at the IsSelected Trigger. You can make the border a different colour so it is not "Ugly" or set it to transparent and it will not be visible when selected.
Hope this helps.
There's an even easier way: set ListBox
property IsHitTestVisible="False"
. This prevents all the items in the list from receiving mouse events. This has the advantage of stopping the highlighting as you mouse-over as well.
It works for me in WP 7.1.
A simple way to do this (using the answer from viky above) is to set the selected index to -1 in the SelectionChanged(), as follows.
public void OnListView_SelectionChanged(Object sender, RoutedEventArgs e)
{
if (null != sender && sender is ListView)
{
ListView lv = sender as ListView;
lv.SelectedIndex = -1;
}
}
Better to avoid events, it's more elegant and without side effects the Style tag.
<ListBox>
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="IsEnabled" Value="False"/>
</Style>
</ListBox.ItemContainerStyle>
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
... what you want as a source ...
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
you can handle SelectionChanged event of ListBox and unselect the selected item in the event handler.
You can also make disabled Listbox, which will give you static, non-interactive listbox.
<ListBox IsEnabled="False"/>
I think this is the solution as simple as possible.
In my case I had templated ListboxItems with a Textblock and a ComboBox. The only "active" should be the Combo...
<ScrollViewer VerticalScrollBarVisibility="Auto"
HorizontalScrollBarVisibility="Disabled"
CanContentScroll="True" />
<ItemsControl>
....here my content....
</Itemscontrol>
</ScrollViewer>
did work for me as expected. BR, Daniel
You can also handle PreviewMouseDown event
And to prevent tap you can set KeyboardNavigation.TabNavigation="None"
<ListView x:Name="Cards"
.....
PreviewMouseDown="CardMonthsDescriptors_OnPreviewMouseDown"
KeyboardNavigation.TabNavigation="None"
>
...
private void Cards_OnPreviewMouseDown(object sender, MouseButtonEventArgs e)
{
e.Handled = true;
}
