我的目标是像这样创建TreeView：
alias1
--TABLES ( constant string )
----TABLE_NAME11
----TABLE_NAME12
----TABLE_NAME13
---- ...
--INDEXES ( constant string )
----INDEX_NAME11
----INDEX_NAME12
---- ...
alias2
--TABLES ( constant string )
----TABLE_NAME21
----TABLE_NAME22
----TABLE_NAME23
---- ...
--INDEXES ( constant string )
----INDEX_NAME21
----INDEX_NAME22
.... (n)
alias(n)
++TABLES ( constant string )
++INDEXES ( constant string )
我想我已经阅读了有关TreeView，HierarhicalDataTemplate的stackoverflow的每个主题，但我不能使结构与此类似。
我尝试将每个主题调整到我的视图模型，但我真的不能。
所以我想我应该一步一步地做。
我的结构总是这样：
alias1
alias2
alias3
alias4
它没有任何扩展别名的按钮。 它只是别名列表。
我的整个XML：
<Grid>
<TabControl>
<TabItem Header="Map">Mapa</TabItem>
<TabItem Header="History">History</TabItem>
<TabItem Header="Aliases">
<Grid>
<TreeView Name="AliasesTree" ItemsSource="{Binding aliases}">
<TreeView.ItemContainerStyle>
<Style TargetType="{x:Type TreeViewItem}">
<Setter Property="IsExpanded" Value="{Binding IsExpanded, Mode=TwoWay}" />
<Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}" />
<Setter Property="FontWeight" Value="Normal" />
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="FontWeight" Value="Bold" />
</Trigger>
</Style.Triggers>
</Style>
</TreeView.ItemContainerStyle>
<TreeView.Resources>
<HierarchicalDataTemplate DataType="{x:Type models:ConnectionModel }"
ItemsSource="{Binding aliases}"
>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding alias}" />
</StackPanel>
</HierarchicalDataTemplate>
<HierarchicalDataTemplate DataType="string">
<StackPanel Orientation="Horizontal">
<TextBlock Text="TABLES" />
<TextBlock Text="INDEXES" />
</StackPanel>
</HierarchicalDataTemplate>
</TreeView.Resources>
</TreeView>
</Grid>
</TabItem>
</TabControl>
</Grid>
我的page.cs文件：
public partial class SideBar : Page
{
public List<ConnectionModel> aliases = ConnectionUtilities.LoadConnections();
public SideBar()
{
InitializeComponent();
LoadSideBar();
DataContext = new { aliases = this.aliases , this.DataContext };
// AliasesTree.ItemsSource = aliases;
}
public async Task LoadSideBar()
{
await LoadAliasTreeView();
}
public async Task LoadAliasTreeView()
{
//aliasTreeView.ItemsSource = ConnectionUtilities.LoadConnections();
OdbcDataAdapter MainOdbcAdapter = new OdbcDataAdapter();
String commandString = "";
foreach (ConnectionModel connection in aliases)
{
await Dispatcher.InvokeAsync(
async () =>
{
using (OdbcConnection con = new OdbcConnection("DSN=" + connection.dsn.ToString()
+ ";UID=" + connection.username.ToString()
+ ";PWD=" + connection.password.ToString()))
{
using (MainOdbcAdapter = new OdbcDataAdapter(commandString, con))
{
if (con.State == ConnectionState.Closed)
con.Open();
await Task.Run(() =>
{
using (DataTable tableschema = con.GetSchema("TABLES"))
{
// first column name
foreach (DataRow row in tableschema.Rows)
{
connection.tables.Add(new TableModel() { TABLE_NAME = row["TABLE_NAME"].ToString() });
// MessageBox.Show( row["TABLE_NAME"].ToString()); Sprawdzone, dziala, pokazuje nazwy tabel
}
}
});
}
}
});
}
//aliasTreeView.ItemsSource = aliases;
}

感谢您的任何建议。
我的下一步将是： 3.展开＆＃34; TABLES＆＃34;到TableModel.TABLE_NAME中的表名列表。
