禁用节点并设置禁用树视图的颜色节点 [英] Disable a node and set the Color of disabled treeview node

问题描述

我有一个以下结构的树视图

 X 
 | --- X1 
 |  - --X2 
 | ..... X11 
 | ..... X12 
 Y 
 | --- Y1 
 | --- Y2 
 | ..... Y11 
 | ..... Y12 
 

禁用时例如，节点Y，我希望所有的子节点也应该被禁用，颜色必须变成灰色。



任何人都可以帮助plz !!

  var  node2 = TreeView1.Nodes [ 1 ];  //  第二个节点 
 node2.SelectAction = TreeNodeSelectAction.None; 
  foreach （TreeNode节点 in  node2.ChildNodes）
 {
 node.SelectAction = TreeNodeSelectAction.None; 
  foreach （TreeNode子节点 in  node.ChildNodes）
 {
 subnode.SelectAction = TreeNodeSelectAction.None; 
 
} 
} 

I have a tree view with the below structure

X
|---X1
|---X2
     |.....X11
     |.....X12
Y
|---Y1
|---Y2
    |.....Y11
    |.....Y12

When I disable for eg, Node Y, I want all the child nodes also should be disabled and the color must become gray.

Can anyone help plz!!

解决方案

Try this

var node2 = TreeView1.Nodes[1]; // second node
           node2.SelectAction = TreeNodeSelectAction.None;
           foreach (TreeNode node in node2.ChildNodes)
           {
               node.SelectAction = TreeNodeSelectAction.None;
               foreach (TreeNode subnode in node.ChildNodes)
               {
                   subnode.SelectAction = TreeNodeSelectAction.None;

               }
           }
