Tree View Control

Hi,

Firstly, great component, thanks. Exactly what I was looking for.

Except... ;o)

I have a multi-level treeview using checkboxes. When the user clicks a check box I want to ensure all parent node check boxes and all child node check boxes are set. IE. If a node is the first at that group level to be checked, ensure all parents are checked, and all children are checked.

Clearly I don't want the NodeCheckChanged event to fire while I'm manually setting state. Bad things happen. Consequently I remove the NodeCheckChanged event handler and reassign it once processing is complete. However, even though I unassign this event using "TreeView.NodeCheckChanged -= TreeView_NodeCheckChanged", the event still fires! I can only assume the TreeView code uses it internally to do something or other.

Is it possible to remove this dependency? It's possble to workaround it using global variables to indicate who fired the event but that's a pretty grubby solution.

Cheers,

I recently downloaded the Silverlight Tree Demo and the Silverlight 4 Version 5.3.2 binaries and then converted the project to run locally in VS2010, Win7 64-bit. However, the downloaded tree demo is not as stable as the online Tree Demo that is on the vectorlight.net site.  For example, in the downloaded version, when the Tree_NodeClick event fires, the Target property of TreeEventArgs is null causing an Object Reference Not Set exception. Additionally, the ‘Selected node’ text in textblock does not synch with the selected node in the tree view. Consequently, I’m wondering if there is a more current version of the tree demo and binaries.

And thanks for making available these controls and source code – much appreciated.

I'm using bold text, italic text, colored text, icons with nodes but I need more effects.  (The node represents a very large abstract object in my code and I'm looking for ways to illustrate many properties of my abstract object via Liquid.Node).

Can I add to my application some of this: strikeout(strikethogh) text, double colored titles of nodes, more the 1 icon for node, maybe some animation?

Maybe I can do all I need using Styles in xaml?

Thank you

Just upgraded from an older version and I can no longer select a node and press F2 to put it in edit mode. Is there a recomended workaround to get that functionality back?

Thanks,

Hi !

i did the size change in runtime - while adding the items

working fine !

tnx

Hi,

The problem here is that when the node expand method is called the size of the child node collection is unknown until the layout of thie children has completed.  Have you tried to update the scroll position using the NodeExpanded event?

Thanks!
