How to Fade a Form Using Windows Forms

In this short article, I will demonstrate how to use the “Opacity” property of the Form to fade it out.

Step 1: Open Visual Studio and create a new application using either C# or VB.NET. Drag a button on the form. Rename the button to “Fade Me” and set its Name property to “btnFade”.

Step 2: Add the System.Threading directive to your class. We will be making the current thread to sleep for 100 milliseconds so that you can see the effect.

using System.Threading; - C#

Imports System.Threading – VB.NET

Step 3: Double click the button. Write the following code on the btnFade click event

C#

private void btnFade_Click(object sender, EventArgs e)

{

int loopctr = 0;

for (loopctr = 100; loopctr >= 5; loopctr -= 10)

{

this.Opacity = loopctr/95.0;

this.Refresh();

Thread.Sleep(100);

}

this.Close();

}

VB.NET

Private Sub btnFade_Click(ByVal sender As Object, ByVal e As EventArgs)

Dim loopctr As Integer = 0

For loopctr = 100 To 5 Step -10

Me.Opacity = loopctr/95.0

Me.Refresh()

Thread.Sleep(100)

Next loopctr

Me.Close()

End Sub

Check out how we use the form’s opacity to fade it out.

Step 4: Run the application. Click on the button and watch the form fade out.

Cool, ain’t it and with just 5 lines of code.
Isn't it a new way to give an animation close effect form to your user. Try it out !!
