Maybe it's just me, but I was expecting the behavior of the Expander would be that everything below it would shift down to make room for the expanded Expander, but I am not seeing this. How is it supposed to work?

Hi Dan,

Thank you for your interest in the RadExpander for Silverlight.

The expander's behavior is exactly what you are talking about. It pushes other controls out. However there is one tricky moment - if the expander is stretched (VerticalAlignment=Stretch) then its size will be calculated according to the layout it resides in. In order to get the desired behavior please put the expander inside a StackPanel.

If you still experience any kind of problem with the expander please sent us your application and we will fix it for you.


Kind regards,
Ivan

Hello Michael,

Thank you for contacting us.

The UI exactly follows the layout of your xaml-code. Both the menu and the expander are placed in a Stack Panel. Because of this the menu will always move according to the expander's size. Please share with us what exactly are your UI goals and we will try to help you.

Looking forward for your reply.


Best wishes,
Ivan

I want the expander to push down the controls below. because inside of the expander control I have a data entry form that a user can fill in. Im attaching a screenshot of a wireframe for the UI that shows where the expander control lives on the screen and how it should behalf. When you look at the screen at the top you will see "Add new customer" that text represents the expand control, so when the user clicks on the "^" it will expand the control and push down the other controls or overlap them.

CAN YOU PLEASE Take down my ui-wireframe from the site!! I didnt know that it would post it directly to the forum. I tried to update my ticket to remove it but i cant!!

Hello Michael,

Sorry for the late response.

In the attached example we are demonstrating some different scenarios. Below is a short description:
  • A "push-down toggle button":
    This button (RadToggleButton) shows/hides a panel. This panel moves down/up all the content beneath it.
  • An "overlap toggle button":
    This button (RadToggleButton) shows/hides a panel. This panel overlaps the content beneath it.
  • A "push-down expander":
    When this expander expands/collapse it moves down/up all the content beneath it.
  • An "overlap expander":
    When this expander expands/collapse it just overlaps the content beneath it.
  • A "drop-down button":
    This button (RadDropDownButton) overlaps the content beneath it.
Note: the only difference between the "push-down" and the "overlap" is the value of the Grid.RowSpan attached property.

Please give it a try and let us know if you have other questions.

Greetings,
Ivan
