TreeNode.BackColor Property

Gets or sets the background color of the tree node.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public Color BackColor { get; set; }

Property Value

Type: System.Drawing.Color
The background Color of the tree node. The default is Color.Empty.

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.

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 : ";
   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");
}
