Add tabs to an existing tab control in WPF C#
提问by Jeebwise
I am trying to add Tabs to a tab control in WPF but nothing appears on the control at runtime. I have tried following the examples I keep seeing. Right now this is what I have but it isn't working
我正在尝试将选项卡添加到 WPF 中的选项卡控件，但在运行时控件上没有显示任何内容。我尝试按照我一直看到的示例进行操作。现在这就是我所拥有的，但它不起作用
_myConnection.Open();
SqlDataReader myReader = myCommand.ExecuteReader();
while (myReader.Read())
{
MessageBox.Show(myReader["SectionName"].ToString());
TabItem newTabItem = new TabItem
{
Header = myReader["SectionName"].ToString(),
Name = myReader["SectionID"].ToString()
};
TabMain.Items.Add(newTabItem);
}
_myConnection.Close();
TabMain.SelectedIndex = 0;

You can add tabs dynamically by using the following code.
您可以使用以下代码动态添加选项卡。
Add the following code to declare tab control instance globally.
添加以下代码以全局声明选项卡控件实例。
TabControl tbControl;
Now, add the following code to the loaded event of the tab control.
现在，将以下代码添加到选项卡控件的加载事件中。
private void tbCtrl_Loaded(object sender, RoutedEventArgs e)
{
tbControl = (sender as TabControl);
}
I have used a button to add new tabs for the existing tab control.
我使用按钮为现有选项卡控件添加新选项卡。
private void btnAdd_Click(object sender, RoutedEventArgs e)
{
TabItem newTabItem = new TabItem
{
Header = "Test",
Name = "Test"
};
tbControl.Items.Add(newTabItem);
}
Following is my tab control xaml view.
以下是我的选项卡控件 xaml 视图。
<TabControl x:Name="tbCtrl" HorizontalAlignment="Left" Height="270" Margin="54,36,0,0" VerticalAlignment="Top" Width="524" Loaded="tbCtrl_Loaded">
<TabItem Header="Tab - 01">
<Grid Background="#FFE5E5E5">
<Button x:Name="btnAdd" Content="Add New Tab" HorizontalAlignment="Left" Margin="68,95,0,0" VerticalAlignment="Top" Width="109" Height="29" Click="btnAdd_Click"/>
</Grid>
</TabItem>
</TabControl>
Finally, using this you can add any amount of tabs dynamically to the existing tab control.
最后，使用它您可以动态地向现有的选项卡控件添加任意数量的选项卡。
Hope this fulfill your need.
希望这能满足您的需求。

Perhaps something in your DB values? I just wrote the most trivial of for loops to test, and this works fine (using just a TabControl and OnLoaded event on the XAML):
也许你的数据库值中有什么？我只是编写了最简单的 for 循环来测试，这很好用（仅在 XAML 上使用 TabControl 和 OnLoaded 事件）：
private void Window_Loaded(object sender, RoutedEventArgs e)
{
for (int i = 1; i <= 3; i++)
{
var item = new TabItem {Header = i.ToString(), Name = $"tab{i}"};
TabMain.Items.Add(item);
}
}
