Dear Support,
I'm using 
I would like to create a custom symbol containing a ComboBox.
The "Node Contents Demo" is very good example, but I would like to give to the end user the capability to add the custom symbol with ComboBox using the palette.
Is there a simpler method to achieve this behavior than customizing dropped generic node in the nodeDropped event (that's only an idea, I've not tried to implement what I wrote)

Thank you

Best Redards

Hi Domenico,

We have analysed your query, we have  created a sample, in which we added combo box as symbol palette item to symbol palette. We set IsHitTestVisible property of combo box as false, since it is exist as content of symbol palette item, so you can drag and drop it from symbol palette. We set focus to combo box, after drag and drop symbol palette item from symbol palette and also set the IsHitTestVisible property of combo box is as true.

Now you can focus to combobox, after drag and drop custom symbol palatte item from symbol palette. For more information, please refer the following sample.

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

Dear Parthiban,
I tried to insert in the custom node an AutoComplete control.
There are some problems:
1. I can not bind to the Autocomplete any source
2. when I save the Diagram what happen to the ItemSource? I nedd to rebind after diagram load?

I've attached your example in where I added the Autocomplete node.

Thank you

Hi Domenico,

Sorry for the delay being caused.

Query: ‘Use AutoComplete as a Custom Tool in Diagram Pallette’

Please download the sample attached with this forum.

In the sample, we have added the AutoComplete control to the SymbolPaletteGroup. To bind the Itemsource in AutoComplete control the following properties have to be set,
1) Source – Custom
2) CustomSource – Name of the Collection
3) IsLoadCustomSourceOnToggle - True
4) IsHistory - False

If these properties are set, the Autocomplete would be loaded with Items as you required.

Please let us know in case of any other queries.
