@Mr. Bungle For others wanting to do this, the best I could do was set the Visibility of the control inside the expander to Collapsed in the xaml, then hooked the Expanded and Collapsed events of the parent expander control and set the visibility of the control inside the expander to Visible (in the Expanded event) and Collapsed (in the Collapsed event). This give a slightly shorter fade in effect, and fade out is gone completely, but at least the layout is working fine.

The fadeexpanderstyle is great, except that it requires the content’s height to be exposed whilst the expander is still in ‘collapsed’ mode. So it means you can’t put some expanders in a vertical stackpanel. Is there any (simplish) modification to the style to allow the height of an expander with style fadeexpanderstyle to be 0 when collapsed?

Hi Ning,

Is it possible to replace the icon of the Expander button with something else. Do you have an example for this. Help is highly appreciated.

Regards,

Thanks for this great control, but I suggest to change the following:

If one put the expand direction to "ExpandRight" and the content is collapsed, the arrow of the toggle button points to the LEFT direction. That's a bit nasty. I suggest to fix the control by letting the arrow of the toggle button pointing by default to the right direction when content is collapsed in ExpandRight-state.

When content is collapsed this behavior would be better for the user because then the arrow of the toggle button points to that direction where the content will appear.

The height of the expander header has changed in the December version. How do I change it – I can’t find any Height property on HeaderedContentControl.Header?

Do you have any examples of animating the dropdown of the expander? I need an expander the starts off as unexpanded, then gradually expands to the full height of the ContentControl. The Fade In/Out and Scale In/Out are good but they require the expander to start off at full height.

Hi Ning,

Thanks for this update. I was hoping to find a sample with the "button" on the right and this appears to do the job.

Thanks,
Martin
