从重复的选项卡访问控件 [英] Accessing Controls from Duplicated Tabs

问题描述

您好，

我正在使用WPF开发一个需要使用动态标签的应用程序。为列表中的每个项目创建一个TabItem，并从隐藏的"tabToDuplicate"复制一个TabItem。并添加到TabControl：

I'm developing an application with WPF that requires the use of dynamic tabs. A TabItem is created for each item in a list and duplicated from a hidden "tabToDuplicate" and added to TabControl:

<TabItem Header=" " Name="tabToDuplicate" Visibility="Hidden">
                <Grid Background="#FFE5E5E5">
                    <DataGrid Name="BookData" Margin="10,10,409,25" RenderTransformOrigin="-0.63,0.07" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"></DataGrid> 
                     <Button Content="Button" HorizontalAlignment="Left" Margin="304,59,0,0" VerticalAlignment="Top" Width="80" Height="23"/>
                  </Grid>
</TabItem>

private void Window_Initialized(object sender, EventArgs e)
{
           foreach (string i in TabList)
                TabControl.Items.Insert(TabControl.Items.Count-1, NewTabItem(i));
}
private TabItem NewTabItem(string Name)
{
            TabItem NewTab = CloneObject(tabToDuplicate);
            NewTab.Name = "tab" + Name;
            NewTab.Header = Name;
            NewTab.Visibility = Visibility.Visible;
            return NewTab;
}

TabItem已成功添加并正确复制。我不确定如何访问在新的重复TabItem中创建的子控件以获取/设置属性等。我可以提供一些建议。

The TabItem is successfully added and duplicated correctly. I'm not sure how to access child controls created within the new duplicated TabItem to get/set properties etc. Please can I have some advice.

谢谢。

推荐答案

WPF答案是你没有。  ;所有属性都应该在XAML中定义，并使用数据绑定来设置属性。

The WPF answer is you don't.  All properties should be defined in XAML and use data binding to set properties.

此外，由于TabControl是从ItemsControl派生的，因此您将使用的过程是拥有定义数据的对象集合在每个选项卡后面（通常是一个ObservableCollection，这样当你需要一个新标签时，你只需在代码中添加一个新对象
，其中包含所需的数据到集合中，WPF将创建新的TabItem）。

Also since the TabControl is derived from ItemsControl the process you would use is to have a collection of objects that define the data behind each tab (usually an ObservableCollection so that when you need a new tab you simply in code add a new object with the needed data to the collection and WPF will create the new TabItem).
