在wpf中以编程方式触发Treview项选择事件

// 获取TreeView中的TreeViewItem对象
TreeViewItem targetItem = FindTreeViewItem(treeView, "目标项");

if (targetItem != null)
{
    // 设置TreeViewItem的IsSelected属性
    targetItem.IsSelected = true;

    // 处理TreeView的SelectedItemChanged事件
    treeView.SelectedItemChanged += TreeView_SelectedItemChanged;
}

// 递归方法，查找TreeViewItem
private TreeViewItem FindTreeViewItem(ItemsControl itemsControl, string itemName)
{
    foreach (var item in itemsControl.Items)
    {
        TreeViewItem treeViewItem = itemsControl.ItemContainerGenerator.ContainerFromItem(item) as TreeViewItem;

        if (treeViewItem != null)
        {
            if (treeViewItem.Header.ToString() == itemName)
            {
                return treeViewItem;
            }
            else
            {
                TreeViewItem childItem = FindTreeViewItem(treeViewItem, itemName);
                if (childItem != null)
                {
                    return childItem;
                }
            }
        }
    }

    return null;
}

// 处理TreeView的SelectedItemChanged事件
private void TreeView_SelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e)
{
    // 执行相应的操作
    // ...
}
