我有一个DropDown列表和2个Radio Buttons。每个按钮更改一次我需要更改DD列表数据源。
XAML:
<Page
x:Class="myapp.MyTags"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:ReqWriter8"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d" Loaded="Page_Loaded">
<Page.Resources>
<CollectionViewSource x:Name="MyAxureHTML" Source="{Binding }"/>
<CollectionViewSource x:Name="MyControlTypeIDs" Source="{Binding }"/>
</Page.Resources>
<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="480*"/>
<ColumnDefinition Width="203*"/>
</Grid.ColumnDefinitions>
<!-- Back button and page title -->
<Grid x:Name="titlePanel" Background="Gray" Grid.ColumnSpan="2">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="120"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<!--Command="{Binding NavigationHelper.GoBackCommand, ElementName=MainPage}"-->
<Button x:Name="backButton" Margin="39,59,0,0"
Style="{StaticResource BackButtonStyle}"
VerticalAlignment="Top"
AutomationProperties.Name="Back"
AutomationProperties.AutomationId="BackButton"
AutomationProperties.ItemType="Navigation Button" Width="71"/>
<TextBlock x:Name="pageTitle" Text="Setup Requirement Statements" Style="{StaticResource HeaderTextStyle}" Grid.Column="1"
IsHitTestVisible="false" TextWrapping="NoWrap" VerticalAlignment="Top" Margin="2,63,-2,0"/>
</Grid>
<RadioButton x:Name="btA" Content="Axure HTML" HorizontalAlignment="Left" Margin="353,184,0,0" VerticalAlignment="Top"/>
<RadioButton x:Name="btB" Content="Balsamiq XML" HorizontalAlignment="Left" Margin="542,184,0,0" VerticalAlignment="Top"/>
<ComboBox x:Name="cbWidget" HorizontalAlignment="Left" Margin="356,297,0,0" VerticalAlignment="Top" Width="307" MaxDropDownHeight="15"/>
</Grid>
</Page>
代码:
Private Sub Init()
Dim dbpath = Path.Combine(Windows.Storage.ApplicationData.Current.LocalFolder.Path, App.DB)
Using db = New SQLiteConnection(dbpath)
tblAxureHTML = From T In db.Table(Of AxureHTML)()
Where T.ClassName IsNot Nothing
Select T
tblControlTypeIDs = From T In db.Table(Of ControlTypeIDs)()
Where T.Name IsNot Nothing
Select T
MyAxureHTML.Source = tblAxureHTML
MyControlTypeIDs.Source = tblControlTypeIDs
db.Dispose()
db.Close()
End Using
cbWidget.ItemsSource = MyAxureHTML
End Sub
DB:SQLite
首先我不知道如何设置DropDown源列表。 其次,需要在选择单选按钮时进行更改。
有什么想法吗?
答案 0 :(得分:0)
要触发加载列表,您可以在Checked
s上注册RadioButton
事件:
<RadioButton x:Name="fruitsChoiceInput" Checked="RadioButton_Checked">Fruits</RadioButton>
<RadioButton x:Name="vegetablesChoiceInput" Checked="RadioButton_Checked">Vegetables</RadioButton>
<ComboBox x:Name="listOutput"></ComboBox>
要设置列表,您可以使用ItemsSource
的{{1}}属性:
ComboBox
