Question

我创建了一个动态创建的父视图和子视图的树视图。还启用了checkbox属性true.hence为每个节点设置了复选框。问题是如何命名这些复选框，以便对于特定用户，如果值为true，则应选中复选框，否则如果值为false，则需要取消选中该复选框。 true或false值存储在db中的特定列中。

Answer 1

请按照我提供的代码，它可能会从您对您的问题的理解中给出一些想法。我也提供了链接。 http://msdn.microsoft.com/en-us/library/wwc698z7(v=vs.90).aspx

private void PrintRecursive(TreeNode treeNode)
{
   // Print the node.
System.Diagnostics.Debug.WriteLine(treeNode.Text);
MessageBox.Show(treeNode.Text);
// Print each node recursively.
foreach (TreeNode tn in treeNode.Nodes)
  { 
    PrintRecursive(tn);
  }
 }

// Call the procedure using the TreeView.
private void CallRecursive(TreeView treeView)
{
// Print each node recursively.
TreeNodeCollection nodes = treeView.Nodes;
foreach (TreeNode n in nodes)
  {
    PrintRecursive(n);
  }
}

您可以通过以下代码检查选中的节点

foreach (TreeNode node in yourtreeview.Nodes)
        {
            if (node.Checked)
            { //here You can check here your parent nodes is checked or not 
                //your calculations 
            }
foreach (TreeNode ChildNode in node.Nodes)
            {
                if (ChildNode.Checked)
                { // here you can check your 2nd level nodes
                }
foreach (TreeNode childofChild in ChildNode.Nodes)
                {
                    if (childofChild.Checked)
                    { here you can check your 3rd level node }
 foreach (TreeNode GrandChildofChild in childofChild.Nodes)
                    {
                        if (GrandChildofChild.Checked)
                        {
                            //here you can check your fourth level node
                        }
                     }
                }
        }
  }
