Get gorgeous, multi-touch charts for your iOS application with just a few lines of code.

The default behavior of the Windows Phone Slides control doens’t allow a user to click on the slider where the value should be set to. Instead, tapping anywhere on the slider will simply result in the slider incrementing by it’s default or given incrementsetting.

Following small piece of code shows how to have the wanted behavior by responding to the Tap- event of the Slider (named mySlider in the following codepiece).

private void UIElement_OnTap(object sender, GestureEventArgs e)
        {
           if (mySlider.Orientation == System.Windows.Controls.Orientation.Horizontal)
            {
                var pos = e.GetPosition(mySlider).X;
                var width = mySlider.ActualWidth;
                mySlider.Value = (pos/width)*mySlider.Maximum;
            }
            else
            {
                var pos = e.GetPosition(mySlider).Y;
                var height = mySlider.ActualHeight;
                mySlider.Value =(1- (pos / height) )* mySlider.Maximum;
            }
        }
