Question

我是WPF新手，我试图在我的TabControl中添加标签。 LoadTable函数返回一个DataTable，其中包含Information，应该为每个Tab表示DataGrid。

for (int i = 1; i <= number_MaxSemester; i++)
{
     TabItem item = new TabItem();

      // Name of TabItem
      item.Header = i + ". Semester";

      //Contains the Data from Database
      item.DataContext = loadTable();

      Tabs.Items.Add(item);
}

loadTable返回Datatable

的函数

    public DataTable loadTable()
    {
        DataTable dt = new DataTable();

        try
        {
            //Open Connection to Database
            using (SQLiteConnection con = new SQLiteConnection(cs))
            {
                //Command string for the Sqlite Command
                string query = "SELECT Fach, Note, Statusfach, Versuch from infostudent WHERE username = + '" + UserName.Content + "'";

                SQLiteDataAdapter dbAdapter = new SQLiteDataAdapter(query, con);


                //Fill Data with SQLite Data
                dbAdapter.Fill(dt);
            }
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }

        return dt;
    }

以下是XAML代码：

<TabControl x:Name="Tabs" Margin="10,61,0,57" Width="584" HorizontalAlignment="Left">
        <TabControl.ItemTemplate>
            <DataTemplate>
                <DataGrid />
            </DataTemplate>
        </TabControl.ItemTemplate>
    </TabControl>

将TabItem的内容属性设置为您的DataTable：

for (int i = 1; i <= number_MaxSemester; i++)
{
  TabItem item = new TabItem();

  // Name of TabItem
  item.Header = i + ". Semester";

  //Contains the Data from Database
  item.Content = loadTable();

  Tabs.Items.Add(item);
}

...并将DataGrid的ItemsSource属性绑定到TabControl的内容模板中的DataTable的DefaultView：

<TabControl x:Name="Tabs">
    <TabControl.ContentTemplate>
        <DataTemplate>
            <StackPanel>
                <DataGrid ItemsSource="{Binding DefaultView}" />
            </StackPanel>
        </DataTemplate>
    </TabControl.ContentTemplate>
</TabControl>

使用Datagrid动态添加Tabitems
