Question

winFrom 中 treeview 加了checkBox 怎么获取选中checkBox的节点呢?

这是父节点选中 子节点全选
我要的是所有选中的子节点的集合

Answer 1

用递归
List<TreeNode> _nodeList = new List<TreeNode>();
private void treeView1_AfterCheck(object sender, TreeViewEventArgs e)
{
TreeNode node = e.Node;
GetCollection(node);
}
private void GetCollection(TreeNode p_node)
{
foreach (TreeNode item in node.Nodes)
{
if (item.Checked == true)
{
_nodeList.Add(item);
}
item.Checked = e.Node.Checked;
}
}

Answer 2

private void treeView1_AfterCheck(object sender, TreeViewEventArgs e)
{
TreeNode node = e.Node;
foreach (TreeNode item in node.Nodes)
{
item.Checked = e.Node.Checked;
}
}
