TreeNode.NodeFont Property

Definition

Gets or sets the font that is used to display the text on the tree node label.

public:
 property System::Drawing::Font ^ NodeFont { System::Drawing::Font ^ get(); void set(System::Drawing::Font ^ value); };
public System.Drawing.Font NodeFont { get; set; }
member this.NodeFont : System.Drawing.Font with get, set
Public Property NodeFont As Font

Property Value

The Font that is used to display the text on the tree node label.

Examples

The following code example changes the size of NodeFont to the specified size and adjusts the ItemHeight of the tree node's parent TreeView control. This example requires that you have a Form with a TreeView control that contains a collection of TreeNode objects, and a ComboBox that contains font sizes.

private:
   void Button1_Click( Object^ /*sender*/, EventArgs^ /*e*/ )
   {
      myTreeView->ItemHeight = 5;
      myTreeView->SelectedNode->NodeFont = gcnew System::Drawing::Font( "Arial",5 );
      
      // Get the font size from combobox.
      String^ selectedString = myComboBox->SelectedItem->ToString();
      int myNodeFontSize = Int32::Parse( selectedString );
      
      // Set the font of root node.
      myTreeView->SelectedNode->NodeFont = gcnew System::Drawing::Font( "Arial",(float)myNodeFontSize );
      for ( int i = 0; i < myTreeView->Nodes[ 0 ]->Nodes->Count; i++ )
      {
         
         // Set the font of child nodes.
         myTreeView->Nodes[ 0 ]->Nodes[ i ]->NodeFont = gcnew System::Drawing::Font( "Arial",(float)myNodeFontSize );

      }
      
      // Get the bounds of the tree node.
      Rectangle myRectangle = myTreeView->SelectedNode->Bounds;
      int myNodeHeight = myRectangle.Height;
      if ( myNodeHeight < myNodeFontSize )
      {
         myNodeHeight = myNodeFontSize;
      }

      myTreeView->ItemHeight = myNodeHeight + 4;
   }
private void Button1_Click(object sender,EventArgs e)
{
   myTreeView.ItemHeight = 5;
   myTreeView.SelectedNode.NodeFont = new Font("Arial",5);

   // Get the font size from combobox.
   string selectedString = myComboBox.SelectedItem.ToString();
   int myNodeFontSize = Int32.Parse(selectedString);

   // Set the font of root node.
   myTreeView.SelectedNode.NodeFont = new Font("Arial",myNodeFontSize);
   for(int i = 0; i < myTreeView.Nodes[0].Nodes.Count; i++)
   {
      // Set the font of child nodes.
      myTreeView.Nodes[0].Nodes[i].NodeFont =
        new Font("Arial",myNodeFontSize);
   }

   // Get the bounds of the tree node.
   Rectangle myRectangle = myTreeView.SelectedNode.Bounds;
   int myNodeHeight = myRectangle.Height;
   if(myNodeHeight < myNodeFontSize)
   {
      myNodeHeight = myNodeFontSize;
   }
   myTreeView.ItemHeight = myNodeHeight + 4;
}
Private Sub Button1_Click(sender As Object, e As EventArgs)
   myTreeView.ItemHeight = 5
   myTreeView.SelectedNode.NodeFont = New Font("Arial", 5)

   ' Get the font size from combobox.
   Dim selectedString As String = myComboBox.SelectedItem.ToString()
   Dim myNodeFontSize As Integer = Int32.Parse(selectedString)

   ' Set the font of root node.
   myTreeView.SelectedNode.NodeFont = New Font("Arial", myNodeFontSize)
   Dim i As Integer
   For  i = 0 To (myTreeView.Nodes(0).Nodes.Count) - 1
      ' Set the font of child nodes.
      myTreeView.Nodes(0).Nodes(i).NodeFont = New Font("Arial", _
        myNodeFontSize)
   Next i

   ' Get the bounds of the tree node.
   Dim myRectangle As Rectangle = myTreeView.SelectedNode.Bounds
   Dim myNodeHeight As Integer = myRectangle.Height
   If myNodeHeight < myNodeFontSize Then
      myNodeHeight = myNodeFontSize
   End If
   myTreeView.ItemHeight = myNodeHeight + 4
End Sub 

Remarks

If null, the Font used is the Font property value of the TreeView control that this node is attached to.

Note

If the node font is larger than the Font property value that is set in the TreeView control, the tree node label text is clipped.
