Node Sizing Behaviour (v2.1)

This relates to a previous post:
http://mindfusion.eu/Forum/YaBB.pl?board=wpfdg_disc;action=display;num=122666904...

Despite setting one of our UserControls to a height, Width, MinHeigh, MinWidth to 0 node resizing still does not work as it used to in the DLLs that were released around July 2008.  In the July version, the UIElement sizing would be overridden by its parent node.  With v2 the UIElement will only resize down to a certain point at which point clipping of the UIElement occurrs.

Isn't this the same behavior that you'd get from other WPF containers, e.g. if you add your control to a StackPanel of the same size as the node?

No - if I place a copy of the control in a stack panel, the stack panel will force the size of the control without clipping
eg control in a stack panel 280x380 - changing the stackpanel to 180x280 will force a control resize.
The current node behaviour does not force the resize.

Our main angle here is that in July your controls worked 'better' than they do now - the fact that the current version more closely follows perhaps the preferred way of control design just means that Julys version was better in this functionality.

Try this version:
https://mindfusion.eu/_beta/wpf_sizesync.zip

The AutoUpdateSize property is now called SizeSyncMode and its values can be set to the following:

- Arrange: This is the default, and what we believe the correct behavior. Resizing the node calls Arrange on the hosted element.

- SetSize: This should be how those July dlls you like so much worked 8) Resizing the node sets the hosted element's Width and Height properties. Let me know if it works well for you now.

- Measure: The node is resized automatically to match the element's DesiredSize.

I hope that helps,
Stoyan
