需要幫助添加複選框到列表視圖在powershell

Question

我目前正在製作一個GUI，將檢索SQL數據庫並備份它們。我的ListView將填充數據庫，但我想顯示每個數據庫旁邊的複選框。這將允許用戶僅備份期望的數據庫。

在Visual Studio中，我添加了4個複選框（僅用於播放並瞭解如何使它們工作）到我的列表視圖。我不完全確定我可以如何在列表數據旁邊顯示覆選框，因爲默認情況下我什麼都看不到。

這是我的WPF代碼看起來像

<Window x:Class="SQLGUI.MainWindow" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
     xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
     xmlns:local="clr-namespace:SQLGUI" 
     mc:Ignorable="d" 
     Title="MainWindow" Height="547.722" Width="861.104" Background="#FF4F4A4A"> 
    <Grid> 
     <ComboBox x:Name="instance" HorizontalAlignment="Left" Margin="10,76,0,0" VerticalAlignment="Top" Width="120"/> 
     <Button x:Name="selectdatabase" Content="Load Database" HorizontalAlignment="Left" Margin="135,76,0,0" VerticalAlignment="Top" Width="92"/> 
     <ListView x:Name="listView" HorizontalAlignment="Left" Height="350" Margin="10,103,0,0" VerticalAlignment="Top" Width="812"> 
      <ListView.View> 
       <GridView> 
        <GridViewColumn Header="Database Name" DisplayMemberBinding ="{Binding 'Database Name'}" Width="200"/> 
        <GridViewColumn Header="Created" DisplayMemberBinding ="{Binding 'Created'}" Width="200"/> 
        <GridViewColumn Header="Last Backup" DisplayMemberBinding ="{Binding 'Last Backup'}" Width="200"/> 
        <GridViewColumn Header="Size(KB)" DisplayMemberBinding ="{Binding 'Size(KB)'}" Width="200"/> 
       </GridView> 
      </ListView.View> 
      <CheckBox x:Name="box1" Content="Test"/> 
      <CheckBox x:Name="box2" Content="Test 2"/> 
      <CheckBox x:Name="box3" Content="Test 3"/> 
      <CheckBox x:Name="box4" Content="Test 4"/> 
     </ListView> 
     <Button x:Name="backup" Content="Backup" HorizontalAlignment="Left" Margin="130,482,0,0" VerticalAlignment="Top" Width="75"/> 

    </Grid> 
</Window> 

，這就是我如何在WPF製表數據

$WPFselectdatabase.add_click({ 
$WPFlistView.items.clear() 
[reflection.assembly]::LoadWithPartialName("Microsoft.Sqlserver.smo") 
$sqlserver=New-Object ("Microsoft.Sqlserver.management.smo.server") "MS-SQL" 
foreach($sqldatabase in $sqlserver.databases){ 
$sqldatabase.name | select-object @{Name='Database Name';EX={$sqldatabase.name}}, @{Name='Created';Ex={$sqldatabase.CreateDate}},@{Name='Last Backup';Ex={$sqldatabase.LastBackupDate}},@{Name='Size(KB)'; EX={($sqldatabase.Size)}} | % {$WPFlistView.AddChild($_)}} 
}) 

Answer 1

ListView.CheckBoxes Property

我認爲你需要添加的複選框屬性到ListView元素：

<ListView x:Name="listView" CheckBoxes="True" HorizontalAlignment="Left" Height="350" Margin="10,103,0,0" VerticalAlignment="Top" Width="812"> 

Answer 2

通過堆棧溢出搜索後，我能夠找到解決方案！

看起來，一個新的GridView列需要添加一個DataTemplate。添加下面的代碼解決了這個問題。

<GridViewColumn> 
    <GridViewColumn.CellTemplate> 
    <DataTemplate> 
     <CheckBox /> 
    </DataTemplate> 
    </GridViewColumn.CellTemplate> 
</GridViewColumn> 

所以最終的GUI代碼結束了尋找這樣

<Window x:Class="SQLGUI.MainWindow" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
     xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
     xmlns:local="clr-namespace:SQLGUI" 
     mc:Ignorable="d" 
     Title="MainWindow" Height="547.722" Width="861.104" Background="#FF4F4A4A"> 
    <Grid> 
     <ComboBox x:Name="instance" HorizontalAlignment="Left" Margin="10,76,0,0" VerticalAlignment="Top" Width="120"/> 
     <Button x:Name="selectdatabase" Content="Load Database" HorizontalAlignment="Left" Margin="135,76,0,0" VerticalAlignment="Top" Width="92"/> 
     <ListView x:Name="listView" HorizontalAlignment="Left" Height="350" Margin="10,103,0,0" VerticalAlignment="Top" Width="834"> 
      <ListView.View> 
       <GridView> 
        <GridViewColumn> 
         <GridViewColumn.CellTemplate> 
          <DataTemplate> 
           <CheckBox /> 
          </DataTemplate> 
         </GridViewColumn.CellTemplate> 
        </GridViewColumn> 
        <GridViewColumn Header="Database Name" DisplayMemberBinding ="{Binding 'Database Name'}" Width="300"/> 
        <GridViewColumn Header="Created" DisplayMemberBinding ="{Binding 'Created'}" Width="200"/> 
        <GridViewColumn Header="Last Backup" DisplayMemberBinding ="{Binding 'Last Backup'}" Width="200"/> 
        <GridViewColumn Header="Size" DisplayMemberBinding ="{Binding 'Size(MB)'}" Width="150"/> 
       </GridView> 
      </ListView.View> 
     </ListView> 
     <Button x:Name="backup" Content="Backup" HorizontalAlignment="Left" Margin="130,482,0,0" VerticalAlignment="Top" Width="75"/> 

    </Grid> 
</Window>
