Examples

The following code example highlights any TreeNode objects a TreeView control that has its Checked property set to true by setting its BackColor property to Yellow. This code requires that you have a TreeView control on a Form with a collection of TreeNode objects.

public:
   void HighlightCheckedNodes()
   {
      int countIndex = 0;
      String^ selectedNode = "Selected customer nodes are : ";
      IEnumerator^ myEnum = myTreeView->Nodes[ 0 ]->Nodes->GetEnumerator();
      while ( myEnum->MoveNext() )
      {
         TreeNode^ myNode = safe_cast<TreeNode^>(myEnum->Current);
         
         // Check whether the tree node is checked.
         if ( myNode->Checked )
         {
            
            // Set the node's backColor.
            myNode->BackColor = Color::Yellow;
            selectedNode = String::Concat( selectedNode, myNode->Text, " " );
            countIndex++;
         }
         else
                  myNode->BackColor = Color::White;
      }

      if ( countIndex > 0 )
            MessageBox::Show( selectedNode );
      else
            MessageBox::Show( "No nodes are selected" );
   }

public void HighlightCheckedNodes()
{
   int countIndex = 0;
   string selectedNode = "Selected customer nodes are : ";
   foreach (TreeNode myNode in myTreeView.Nodes[0].Nodes)
   {
      // Check whether the tree node is checked.
      if(myNode.Checked)
      {
         // Set the node's backColor.
         myNode.BackColor = Color.Yellow;
         selectedNode += myNode.Text+" ";
         countIndex++;
      }
      else
            {
                myNode.BackColor = Color.White;
            }
        }

   if(countIndex > 0)
      MessageBox.Show(selectedNode);
   else
      MessageBox.Show("No nodes are selected");
}

Public Sub HighlightCheckedNodes()
   Dim countIndex As Integer = 0
   Dim selectedNode As String = "Selected customer nodes are : "
   Dim myNode As TreeNode
   For Each myNode In  myTreeView.Nodes(0).Nodes
      ' Check whether the tree node is checked.
      If myNode.Checked Then
         ' Set the node's backColor.
         myNode.BackColor = Color.Yellow
         selectedNode += myNode.Text + " "
         countIndex += 1
      Else
         myNode.BackColor = Color.White
      End If
   Next myNode

   If countIndex > 0 Then
      MessageBox.Show(selectedNode)
   Else
      MessageBox.Show("No nodes are selected")
   End If
End Sub

Remarks

If the BackColor property is set to Color.Empty, the Color used is the BackColor property value of the TreeView control that the tree node is assigned to.
