[英]Control Template used in Code Behind to add dynamically to a StackPanel
[英]Dynamically adding contents to stackpanel in code behind
我試圖在后面的代碼中在堆棧面板中添加標簽和圖像的集合,最后將那個堆棧面板附加到網格控件的特定列上,我的預期輸出應該像
<image><label>
組合
但是我的輸出就像它在網格的第一列中顯示標簽,在下一列中顯示圖像。(由於我沒有足夠的聲譽,所以我無法添加快照)
XAML代碼
<Window x:Class="Ping.MainWindow" WindowStyle="ThreeDBorderWindow" Icon="F:\ChatApplication\Ping\Ping\Images\title.ico" Cursor="Pen"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Ping - Connected by alphabets" Height="450" Width="750" WindowStartupLocation="CenterScreen" SizeToContent="WidthAndHeight" >
<Grid Name="grid_window">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="200"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<GridSplitter HorizontalAlignment="Right"
VerticalAlignment="Stretch"
Grid.Column="1" ResizeBehavior="PreviousAndNext"
Width="5" Background="#FFBCBCBC"/>
<TabControl Grid.ColumnSpan="2" Name="tab_control" BorderBrush="Cornsilk" BorderThickness="4" HorizontalAlignment="Left" Height="419" Margin="227,0,0,0" VerticalAlignment="Top" Width="515">
<TabItem Header="Home" BorderBrush="Green"/>
</TabControl>
</Grid>
背后的代碼
public MainWindow()
{
InitializeComponent();
DBCoding dbobj = new DBCoding();
//Contains names {"Dhivi","Walle"}
List<string> online = new List<string>();
online = dbobj.onlineUsers();
StackPanel myStackPanel = new StackPanel();
myStackPanel.Orientation = Orientation.Vertical;
foreach (var item in online)
{
Image myImage = new Image();
myImage.Source = new BitmapImage(new Uri("F:\\ChatApplication\\Ping\\Ping\\Images\\visible.png"));
myImage.Width = 10;
myImage.Height = 10;
//myImage.Margin = new Thickness(-10,0,-80,0);
myImage.Height = 10;
Label user = new Label();
user.Content = item.ToString();
myStackPanel.Children.Add(myImage);
myStackPanel.Children.Add(user);
}
grid_window.Children.Add(myStackPanel);
Grid.SetColumnSpan(myStackPanel, 1);
Grid.SetColumn(myStackPanel, 0);
}
誰能告訴我解決方案。
使用數據綁定, ItemsControl
和DataTemplate
如下所示:
XAML
<Window x:Class="Ping.MainWindow" WindowStyle="ThreeDBorderWindow" Icon="F:\ChatApplication\Ping\Ping\Images\title.ico" Cursor="Pen"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Ping - Connected by alphabets" Height="450" Width="750" WindowStartupLocation="CenterScreen" SizeToContent="WidthAndHeight" >
<Grid Name="grid_window">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="200"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<GridSplitter HorizontalAlignment="Right"
VerticalAlignment="Stretch"
Grid.Column="1" ResizeBehavior="PreviousAndNext"
Width="5" Background="#FFBCBCBC"/>
<TabControl Grid.ColumnSpan="2" Name="tab_control" BorderBrush="Cornsilk" BorderThickness="4" HorizontalAlignment="Left" Height="419" Margin="227,0,0,0" VerticalAlignment="Top" Width="515">
<TabItem Header="Home" BorderBrush="Green"/>
</TabControl>
<ItemsControl ItemsSource="{Binding}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<DockPanel>
<!-- You really should add the image as a resource to the project -->
<Image Source="F:\ChatApplication\Ping\Ping\Images\visible.png"
Width="10" Height="10" />
<TextBlock Text="{Binding}" />
</DockPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
C#
public MainWindow()
{
InitializeComponent();
DBCoding dbobj = new DBCoding();
List<string> online = dbobj.onlineUsers();
DataContext = online;
}
