Question

Is there any way to make the form semi-transparent while it is being moved and then become opaque when it’s not being moved anymore? I have tried the Form_Move event with no luck.
I’m stuck, any help?

Answer 1

The reason the form loads as semi-transparent is because the form has to be moved into the starting position, which triggers the Move event. You can overcome that by basing whether the opacity is set, on whether the form has fully loaded.

The ResizeEnd event fires after a form has finished moving, so something like this should work:

bool canMove = false;

private void Form1_Load(object sender, EventArgs e)
{
    canMove = true;
}

private void Form1_Move(object sender, EventArgs e)
{
    if (canMove)
    {
        this.Opacity = 0.5;
    }
}

private void Form1_ResizeEnd(object sender, EventArgs e)
{
    this.Opacity = 1;
}
