1、循环往treeview中添加数据
public AuthorNavUserControl()
{
InitializeComponent();
LoadTrees(MainForm.ProjectId,treeView1.Nodes); } private void LoadTrees(Guid guid, TreeNodeCollection treeNodeCollection)
{
List<IetmProject> ietmProjectlist = new List<IetmProject>();
IIetmProjectService itemProjectService = new IetmProjectService();
ietmProjectlist = itemProjectService.GetIetmProjectId(guid); if (ietmProjectlist != null)
{
foreach (IetmProject item in ietmProjectlist)
{
TreeNode node = treeNodeCollection.Add(item.MICName);
node.Tag = item.ObjectId;
LoadTrees((Guid)item.ObjectId, node.Nodes);
}
}
}
2、右击节点弹出“显示”菜单，点击“显示”后弹出该节点的id值
private void treeView1_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
Point ClickPoint = new Point(e.X, e.Y);
TreeNode CurrentNode = treeView1.GetNodeAt(ClickPoint);
if (CurrentNode is TreeNode)//判断点的是不是一个节点
{
treeView1.SelectedNode = CurrentNode;
CurrentNode.ContextMenuStrip = this.contextMenuStrip1;
contextMenuStrip1.Show(MousePosition);
}
}
} private void 显示ToolStripMenuItem_Click(object sender, EventArgs e)
{
MessageBox.Show(treeView1.SelectedNode.Tag.ToString());
}
