将列表转换为TreeViewItems [英] Converting a list into TreeViewItems

问题描述

我有一个TransactionTypes列表，我希望将它们中的每个作为Nodes/TreeViewItems添加到TreeView的另一个TreeViewItem下，称为'Audit'.

I have a list of TransactionTypes and I want each of these to be added as Nodes / TreeViewItems on a TreeView, under another TreeViewItem called 'Audit'.

是否可以将列表中的每个项目转换为TreeView中的新TreeViewItem?如果是这样，如何才能最有效地完成呢?

Is there a way to convert each individual item in the list into a new TreeViewItem in a TreeView? And if so, how can it be done most efficiently?

谢谢.

我们正在使用WPF应用程序，因此无法使用.Nodes/TreeNodes.

We are using a WPF application and therefore can't use .Nodes / TreeNodes.

推荐答案

这应该有效

List<TransactionTypes> lstTrans ;
TreeViewItem auditNode ;

//code that initializes lsTrans
//code that initializes auditNode 

foreach(TransactionTypes tt in lstTrans)
{
    auditNode.Items.Add(new TreeViewItem() { Header = tt.someStringProperty });
}

这假设您的TreeViewItem具有header属性，并且声明与此类似

This is asumming that your TreeViewItem has a header property and is declared similar to this

<TreeView>
    <TreeViewItem Header="initialValue"></TreeViewItem>
</TreeView>

使用LINQ可能有一种更紧凑的方法，但内部仍然是循环

There is probably a more compact way using LINQ but internally is still a loop

以下是 在WPF中使用TreeView
