Palette control is a Diagram that holds parts that can be dragged to a Diagram.
Syntax
Remarks
You will need to initialize the palette's Diagram.Model with the node data with which you wish to populate the palette. For example, for the (simple) palette:
<go:Palette x:Name="myPalette" NodeTemplate="..." />
you would need to perform something like the following at initialization: myPalette.Model.NodesSource = new String[] {
"Alpha", "Beta", "Gamma"
};
You also need to set AllowDrop="True" on the Diagram(s) into which users may drop the items from the palette.
It is commonplace to have a different and probably simpler node DataTemplate for Palettes than for the destination Diagrams.
By default a palette uses a Northwoods.GoXam.Layout.GridLayout as its Layout. That GridLayout defaults to sorting all of the nodes by the Part.Text (attached) property. It also re-layouts automatically whenever the viewport size changes, because the size of the DiagramPanel changes or because the scale changes.
The default style for a palette also makes it IsReadOnly, and sets AllowDragOut to be true, to permit drag-and-drop operations to start from this palette and to end on other diagrams.
