How to Display a Notification Form Without Stealing Focus?

Preventing Focus Theft in Notification Forms

Bottom-of-screen notification forms often cause focus issues, interrupting user workflow. Here's how to prevent this disruptive behavior.

Method 1: Using ShowWithoutActivation

The simplest solution is to override the Form.ShowWithoutActivation property. Setting this to true displays the form without activating it.

<code class="language-csharp">protected override bool ShowWithoutActivation
{
  get { return true; }
}</code>

Method 2: Customizing CreateParams

For more control, override the CreateParams method. Using the WS_EX_NOACTIVATE and WS_EX_TOOLWINDOW flags prevents activation and standard window behavior.

<code class="language-csharp">protected override CreateParams CreateParams
{
  get
  {
    CreateParams baseParams = base.CreateParams;

    const int WS_EX_NOACTIVATE = 0x08000000;
    const int WS_EX_TOOLWINDOW = 0x00000080;
    baseParams.ExStyle |= (int)(WS_EX_NOACTIVATE | WS_EX_TOOLWINDOW);

    return baseParams;
  }
}</code>

Either method ensures your notification form appears without stealing focus from the main application, maintaining a smooth user experience.
