  Hi
  
  In the scaling and zooming demo the controls display a popup.  How would I make something similar but which allows editing?  I'm after something like the toolbar in Word2007 that appears semi-transparent but then goes solid and allows interaction when I move my mouse over it.
  
  Thanks
  
  Sean

  Hi Sean,
  
  The approach used in the Item Scaling demo for RadComboBox is appropriate just for this example and is meant to show the capabilities of RadComboBox. However, I am afraid this approach is not applicable to your scenario.
  
  If you have additional questions, do not hesitate to contact me.

  Hi Nikolay
  
  Could you suggest one of your controls that would do the job then, please?
  
  Thanks

  Hello Sean,
  
  In order to have richer examples, we have created a specific popup control - ZoomPopup (used in the "Business Cards" integration example as well as in the RadComboBox "Item Scaling" example). Unfortunately, ZoomPopup can be used for zooming popups only.
  
  If you need to animate opacity instead of zooming, you will have to make it on your own. We will consider adding such a popup in the future.
  
  The easiest way to achieve a popup that has opacity animation is by inheriting MS Form and using its Opacity property. Set the form FormBorderStyle property to None, StartPosition property to Manual and Bounds property to the rectangle of the popup. Then animate the Opacity from 0 to 1.
  
  You will have to use a mouse hook or a message filter to detect conditions for closing the popup (such as moving the mouse out of the area of the popup or receiving WM_ACTIVATEAPP).
  
  Since Form is a top-level window, special care should be taken for the window activation (and the WM_NCACTIVATE message).
  
  For more information on how to make a form to be a popup window - please consult the article below:

  Hi Angel
  
  Thanks for the response.  It's a shame that your controls do not (yet) do what I would like, but I really appreciate your clear response.  I will look into what you mention.
  
  Regards

  Hi kiran,
  
  We have two zoom features, which can be seen in the examples that come with the installation:
  

  1. Zoomable elements (this is available from the first version of RadControls for WinForms - Q4 2006) - the elements inside a control are zoomed according to their ScaleTransform property.
     In Q1 2008 examples, this feature is presented in:
     "RadControls Integration" -> "Bubble Bar" and
     "RadControls Integration" -> "Magnifier".
     In "RadControls Integration" -> "Photo Album" both scaling and rotation are shown.
      
  2. Zoomable popup (available since Q1 2007) - a popup control is shown with zooming animation.
     In Q1 2008 examples, this feature is presented in:
     "RadControls Integration" -> "Business Cards" and
     "Editors" -> "RadCombox" -> "Item Scaling".

  I hope this helps. If you have any further questions, please contact me.

  Sincerely yours,
  Angel

  Hi kiran,
  
  Thank you for getting back to us.
  
  At this time, the WinForms chart does not support the functionality you are looking for. We are also not planning to implement it. Interestingly, you are the first customer to request such a feature. If more customers express interest, we will consider implementing this feature.
  
  Contact us again if you have further questions.

  Hello,
  
  I have been trying to animate the Opacity property of a RadGridView, but I am unable to do it. Here is the Code I'm using:
          Dim ve As VisualElement = Me.RadGridView1.RootElement
          Dim animateOpacity As AnimatedPropertySetting = _
          New AnimatedPropertySetting(VisualElement.OpacityProperty, _
                                      0.0F, _
                                      1.0F, _
                                      10, 30)
          animateOpacity .RemoveAfterApply = True
          animateOpacity .ApplyValue(re)
  
  Thank you,

  Hi tanioskahi,
  
  Here is the code to toggle the opacity of RadGridView with animation
  
  

  Dim re As VisualElement = Me.RadGridView1.RootElement

  Dim animateOpacity As AnimatedPropertySetting = Nothing

  If Me.RadGridView1.RootElement.Opacity = 1D Then

  animateOpacity = New AnimatedPropertySetting(VisualElement.OpacityProperty, CDbl(1), CDbl(0), 10, 30)

  ElseIf Me.RadGridView1.RootElement.Opacity = 0D Then

  animateOpacity = New AnimatedPropertySetting(VisualElement.OpacityProperty, CDbl(0), CDbl(1), 10, 30)

  End If

  If Not animateOpacity Is Nothing Then

  animateOpacity.RemoveAfterApply = True

  animateOpacity.ApplyValue(re)

  End If

  
  Let me know if this does not work for you.

  Hello Mike,
  The opacity animation looks fine, nevertheless, when animated, the component hides all elements that are behind it and show only the form solid background.
  Thank you,

  Hi Tanioskahi,
  
  This is the expected behavior for all controls in Windows Forms. The opacity implementation is limited to the parent control. According to this MS article, There is a way though to implement a control that is completely transparent though painting the parent control and all its children on its background. I modified the sample code to fix some problems and fit it in our scenario. Please find the project attached.
