.NET Anchoring a ListBox bug

[Guest]

I am anchoring a ListBox to the top and bottom of a windows form. I launch
the application minimized. If I use a font other than the default MS Sans
Serif, the list box is docked to the right and bottom edges when I restore
it.

I have seen references to some bugs concerning anchoring, but I could find
no specific mention of this listbox problem.

For now, I can get by using the MS Sans Serif font, but is there a
workaround? (Other than catching the resize method and doing it manually).

I admit that I only tried a few fonts other thant the default, but they all
behaved badly.

Hello Kentonis,

I assume your using .NET Framework 1.1 ? It would be helpful if you could post the code to produce this bug.

Best of luck!

Hello RBischoff,

Yes, .NET Framework 1.1. All you have to do is create a C# Windows project,
drop a listbox on the form (with some space from the sides), anchor it to all
four sides and build it. Once you have verified that it behaves as expected,
go back and change the font property in designer mode and rebuild. Then the
listbox will act as if it is docked to the right and bottom.
I made no manual code changes.

Here is the form code:

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;

namespace AnchorTest
{
/// <summary>
/// Summary description for Form1.
/// </summary>
public class Form1 : System.Windows.Forms.Form
{
private System.Windows.Forms.ListBox listBox1;
public System.Windows.Forms.ToolBar toolBar1;
private System.Windows.Forms.Label label1;
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.Container components = null;

public Form1()
{
//
// Required for Windows Form Designer support
//
InitializeComponent();

//
// TODO: Add any constructor code after InitializeComponent call
//
}

/// <summary>
/// Clean up any resources being used.
/// </summary>
protected override void Dispose( bool disposing )
{
if( disposing )
{
if (components != null)
{
components.Dispose();
}
}
base.Dispose( disposing );
}

#region Windows Form Designer generated code

/// the contents of this method with the code editor.

{
this.listBox1 = new System.Windows.Forms.ListBox();

this.label1 = new System.Windows.Forms.Label();
this.SuspendLayout();
//

this.listBox1.Cursor = System.Windows.Forms.Cursors.Hand;
this.listBox1.Font = new System.Drawing.Font("Lucida Console",
8.25F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point,
((System.Byte)(0)));
this.listBox1.ItemHeight = 11;
this.listBox1.Location = new System.Drawing.Point(16, 72);
this.listBox1.Name = "listBox1";
this.listBox1.Size = new System.Drawing.Size(592, 279);
this.listBox1.TabIndex = 0;
//

this.toolBar1.Divider = false;
this.toolBar1.Dock = System.Windows.Forms.DockStyle.None;

this.label1.TabIndex = 2;
this.label1.Text = "This is form 1";
//
// Form1
//
this.AutoScaleBaseSize = new System.Drawing.Size(5, 13);
this.ClientSize = new System.Drawing.Size(632, 558);
this.Controls.Add(this.label1);
this.Controls.Add(this.listBox1);
this.Controls.Add(this.toolBar1);
this.Name = "Form1";
this.Text = "Form1";
this.ResumeLayout(false);
