Dear Support,
I have to use version and SL5.

My need is to create custom nodes in the palette to be used to build a diagram.

Trying the example in 
I can place a Node in the palette but when I click on it to drag and drop on the diagram area an Exception in thrown.

I tried also to customize a palette symbol in another way, loading a Canvas with various objects. Well in this case the node is placed in the palette and is visible, but when dragged on the diagram it become invisible.

Where are my mistakes?

It' quite urgent to give feedback to our customers

Best Regards

Hi Domenico,

We have analyzed your query “CustomNodes in SymbolPalette”, Node’s mouse move event will be fire when we move the mouse onto the Node (SymbolPaletteItem’s Content). So that an exception is raised. So please set IshitTestVisible property of the Node as false till drag and drop the SymbolPaletteItem from SymbolPalette. Please refer the following code snippet.


Code Snippet :

node.IsHitTestVisible = false;


And also, we have created a simple sample for your reference. Please refer the sample for more information.

Please let us know if you require further assistance on this.
