drawing label close to text box

[Not-So-Lazy]

Hi

In delphi we have something like Labeled Edit which is basically text box
which draws label side by it. Is it possible in C# when inheriting from
textbox class?
( not from UserControl because its imposible to align when anhors set to Top
and labels are not same width)

TIA

The following code might have some problems but it should show you how it might
be done.


public partial class MyLabeledTextBox : TextBox
{
private Label _myLabel = null;

public MyLabeledTextBox() : base()
{
}

protected override void OnParentChanged(EventArgs e)
{
if (this.Parent != null)
{
_myLabel = new Label();
_myLabel.Text = this.Name; // something mor intelligent needed here
_myLabel.Left = this.Left - 150; // and here also
_myLabel.Top = this.Top;
this.Parent.Controls.Add(_myLabel);
}
base.OnParentChanged(e);
}

protected override void OnLocationChanged(EventArgs e)
{
if (_myLabel != null)
{
_myLabel.Left = this.Left - 150;
_myLabel.Top = this.Top;
}
base.OnLocationChanged(e);
}

protected override void Dispose(bool disposing)
{
if (_myLabel != null)
_myLabel.Dispose();
base.Dispose(disposing);
}
}

protected override void Dispose(bool disposing)
{
if (_myLabel != null)
_myLabel.Dispose();
base.Dispose(disposing);
}
}

all works excellent except that i put disposing code into designer.cs file
protected override void Dispose(bool disposing)
{
if (_myLabel != null)
_myLabel.Dispose();
if (disposing && (components != null))
{

components.Dispose();
}
base.Dispose(disposing);
}

And now label is beign destroyed nicely... Thank You very much


PS any idea how to enforce VC# Express to rebuild code of my dll ? now i
just delete reference and place it one more time, but this is not very handy
especially when you making changes every minute. i added control project to
my test form solution and i do rebuild and it says rebuild all succeded, but
when i open properties of my control it doesnt show properties taht i just
added.... strange
