本文实例讲述了C#搜索TreeView子节点,保留父节点的方法。分享给大家供大家参考。具体如下：
C# 搜索TreeView子节点保留父节点：
private void selectNodeByName( string name)
{
//重新生生成树,
InitTvCatalog();
//删除节点
selectNode(tvCatalog.Nodes, name);
}
private void selectNode(TreeNodeCollection nodes, string name)
{
bool del = true ;
for ( int i = nodes.Count - 1; i >= 0; i--)
{
TreeNode node = nodes[i];
del = true ;
if (node.Nodes.Count != 0)
{
selectNode(node.Nodes, name);
}
if (node.Text.StartsWith(name, StringComparison.OrdinalIgnoreCase))
{
del = false ;
}
else
{
del = true ;
}
if (del && node.Nodes.Count == 0)
{
node.Remove();
}
}
tvCatalog.ExpandAll();
}
WPF搜索TreeView子节点保留父节点：
private void selectNodeByName( string name)
{
//重新生生成树,
method = new Common.PublicMethod();
method.TreeViewLoad();
//删除节点
selectNode(RegimeSetting.Common.StaticVariables.treeView.Items, name);
method = null ;
}
private void selectNode(ItemCollection nodes, string name)
{
bool del = true ;
for ( int i = nodes.Count - 1; i >= 0; i--)
{
TreeViewItem node = nodes[i] as TreeViewItem;
del = true ;
if (node.Items.Count != 0)
{
selectNode(node.Items, name);
}
if (node.Header.ToString().StartsWith(name, StringComparison.OrdinalIgnoreCase))
{
del = false ;
}
else
{
del = true ;
}
if (del && node.Items.Count == 0)
{
if ((node.Parent as TreeViewItem) != null )
(node.Parent as TreeViewItem).Items.Remove(node);
else
(node.Parent as TreeView).Items.Remove(node);
}
}
(RegimeSetting.Common.StaticVariables.treeView.Items[0] as TreeViewItem).IsExpanded = true ;
}
希望本文所述对大家的C#程序设计有所帮助。
