绑定数据后遍历WPF treeView的所有节点 [英] Exapned all the nodes of WPF treeView after databinding

问题描述

将WPF树视图绑定到对象后，如何扩展WPF树视图的所有节点.我在下面使用了代码

How we can expend all the nodes of WPF treeview once i have bound it to object. I have used code below

for (int i = 0; i < TreeViewLocal.Items.Count;i++)
            {
                TreeViewItem t2 = (TreeViewItem)TreeViewLocal.ItemContainerGenerator.ContainerFromItem(TreeViewLocal.Items[i]);
                t2.IsExpanded = true;
            }

但正如您所看到的，它将消耗顶级节点.对此高度赞赏的

But as you can see it will expends top level nodes.Any help on this highly appreciated

This[^] will surely help you out.

尝试为您添加到TreeView的每个TreeViewItem手动将IsExpanded属性设置为IsTrue.

Try setting manually the IsExpanded property to IsTrue for every TreeViewItem you add to your TreeView.
