A small and easy to use notification bar like that found in IE6+ and Firefox web browsers.

Introduction

The NotificationBar gives you an easy to use control that can replace message boxes / pop up boxes where they are not really needed. When the need arises to display a small amount of information without distracting users with pop ups, this would be a solution worth checking out.

Anyone who has used IE6+ on Win XP SP2+ knows about those Information / Notification bars you get when trying to download a file etc. That is what I have brought here today. A small, completely C# version of that control.

Current Features

  • Fast
  • Works on .NET and Mono
  • Can be used in commercial projects
  • Can flash control any number of times
  • Can use animation when showing and hiding the control
  • Can play sound when shown
  • Automatic word-wrap

Using the code

This control is very easy to use.

The classes and methods included in this library are listed below.

NotificationBar

Extending the Control class, the NotificationBar class is the only class in the library and houses the control.

  • OnClickMenuStrip
  • Sets the ContextMenuStrip seen when the control is clicked.

  • SmallImageList
  • Sets the ImageList used for displaying an image on the far left side of the control.

  • ImageIndex
  • Sets the image index of an image in the SmallImageList to be used in the control.

  • NotificationBar
  • The class constructor method.

  • DrawText
  • Draws the text seen on the control.

  • DrawCloseButton
  • Draws the close button seen on the far right side of the control.

Overridden methods and properties where left out of the list above.

Using the control is as easy as this:

//Add the using statement for the control's namespace
using WinComponents.Controls; 
//Then add the control your font, text, and anything else.
NotificationBar infoBar = new NotificationBar ();
infoBar.Name = "informationBar1";
infoBar.Size = new Size(100, 20);
infoBar.Dock = DockStyle.Top;
infoBar.Font = new Font(FontFamily.GenericSansSerif, 8.25f);
infoBar.Text = "Hello, here is some info!";
infoBar.Show();  
//Adding a pop-up menu or an image is as simple as
infoBar.OnClickMenuStrip = contextMenuStrip1;
infoBar.SmallImageList = imageList1;
infoBar.ImageIndex = 2;

These are the results you should get:

Normal view of information bar with short string:

Hovered view of information bar with short string:

And finally, the normal and hovered states with a longer string:
