WPF: TabControl and dynamic TabItems
提问by Kat Ze
I am trying to create a GUI for my current project using WPF in C#. I would like to have tabs (dynamically created at runtime) and each tab should open a table with the same column headers but different contents.
我正在尝试使用 C# 中的 WPF 为我当前的项目创建一个 GUI。我想要选项卡（在运行时动态创建），并且每个选项卡都应该打开一个具有相同列标题但内容不同的表。
I know I could realize tabs and tables like this:
我知道我可以实现这样的标签和表格：
<Grid>
<TabControl x:Name="tabControl" TabStripPlacement="Left">
<TabItem Header="Example 1" x:Name="tabItem" >
<DataGrid ItemsSource="{Binding TagCollection.Tags}" AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTextColumn Header="Tag" Binding="{Binding Tag}" />
<DataGridTextColumn Header="Description" Binding="{Binding Description}" />
<DataGridTextColumn Header="Value" Binding="{Binding Value}" />
</DataGrid.Columns>
</DataGrid>
</TabItem>
<TabItem Header="Example 2" x:Name="tabItem1" >
<DataGrid ItemsSource="{Binding TagCollection.Tags}" AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTextColumn Header="Tag" Binding="{Binding Tag}" />
<DataGridTextColumn Header="Description" Binding="{Binding Description}" />
<DataGridTextColumn Header="Value" Binding="{Binding Value}" />
</DataGrid.Columns>
</DataGrid>
</TabItem>
</TabControl>
</Grid>
How can I produce a view like that with code behind? I am not used to Bindings and such things yet, so perhaps someone could show me a short example?
我怎样才能产生这样的视图，后面有代码？我还不习惯绑定之类的东西，所以也许有人可以给我看一个简短的例子？
Thanks KatZe

I have create a sample project DynamicTabs. Some sample context in constructor:
我创建了一个示例项目 DynamicTabs。构造函数中的一些示例上下文：
var tabs = new ObservableCollection<MyTab>();
int tabsCount = 5;
for (var i = 1; i <= tabsCount; i++)
{
var tab = new MyTab() {Header = "Tab " + i};
tab.Data.Add(new MyTabData() {Column1 = "col1" + i, Column2 = "col2" + i, Column3 = "col3" + i});
tabs.Add(tab);
}
DataContext = tabs;
Classes for sample context:
示例上下文的类：
public class MyTab
{
public string Header { get; set; }
public ObservableCollection<MyTabData> Data { get; } = new ObservableCollection<MyTabData>();
}
public class MyTabData
{
public string Column1 { get; set; }
public string Column2 { get; set; }
public string Column3 { get; set; }
}
And XAML:
和 XAML：
<Window x:Class="DynamicTabs.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:DynamicTabs"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525">
<TabControl ItemsSource="{Binding}">
<TabControl.ItemTemplate>
<DataTemplate DataType="local:MyTab">
<TextBlock Text="{Binding Header}"/>
</DataTemplate>
</TabControl.ItemTemplate>
<TabControl.ContentTemplate>
<DataTemplate DataType="local:MyTab">
<DataGrid ItemsSource="{Binding Data}">
<DataGrid.Columns>
<DataGridTextColumn Header="Column 1" Binding="{Binding Column1}" />
<DataGridTextColumn Header="Column 2" Binding="{Binding Column2}" />
<DataGridTextColumn Header="Column 3" Binding="{Binding Column3}" />
</DataGrid.Columns>
</DataGrid>
</DataTemplate>
</TabControl.ContentTemplate>
</TabControl>
ItemTemplate is for Header part of TabPage and ContentTemplate for Content of each TabPage.
ItemTemplate 用于 TabPage 的 Header 部分，ContentTemplate 用于每个 TabPage 的 Content。

With some minor updates to your code-behind, you should be able to do this with :
通过对您的代码隐藏进行一些小的更新，您应该能够使用以下方法执行此操作：
<TabControl x:Name="tabControl" TabStripPlacement="Left" ItemsSource="{Binding Path=TableCollection}">
<TabControl.ItemTemplate>
<DataTemplate DataType="{x:Type YourTableType}">
<TabItem Header={Binding TableName}>
<DataGrid ItemsSource="{Binding Rows}" AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTextColumn Header="Tag" Binding="{Binding Tag}" />
<DataGridTextColumn Header="Description" Binding="{Binding Description}" />
<DataGridTextColumn Header="Value" Binding="{Binding Value}" />
</DataGrid.Columns>
</DataGrid>
</TabItem>
</DataTemplate>
</TabControl.ItemTemplate>
</TabControl>
Simply replace the properties in bindings according to your own needs.
只需根据自己的需要替换绑定中的属性。
