 Hi,

I would like to get the attention of the user by making the rad button blink and change the back color to red. How can this be done? Please advise.

Thanks
RJ

Hi RJ,

Thank you for writing. 

The easiest way to achieve this is by using a timer. Here is a small sample:
protected override void OnLoad(EventArgs e)
{
    base.OnLoad(e);
 
    System.Windows.Forms.Timer timer = new Timer();
    timer.Interval = 200;
    timer.Tick += timer_Tick;
    timer.Start();
}
 
void timer_Tick(object sender, EventArgs e)
{
    if (radButton1.ButtonElement.ButtonFillElement.BackColor == Color.Red)
    {
        radButton1.ButtonElement.ButtonFillElement.ResetValue(FillPrimitive.BackColorProperty, ValueResetFlags.Local);
        radButton1.ButtonElement.ButtonFillElement.ResetValue(FillPrimitive.GradientStyleProperty, ValueResetFlags.Local);
    }
    else
    {
        radButton1.ButtonElement.ButtonFillElement.GradientStyle = GradientStyles.Solid;
        radButton1.ButtonElement.ButtonFillElement.BackColor = Color.Red;
    }
}

I hope this helps. 

Regards,
Stefan

Hi Stefan,

Thanks so much, this works perfectly. In the buttons click event, I stopped the timer and tried to reset the button but the buttons border stayed red. How can I bring it back to its default state.

Hi Stefan,

I just released that the border was showing because the button still had focus.

Thank you for all your help.
