I was wondering if you can make a dynamic pallette. I have a program that has a list of elements, and what I would like to do is dynamically change my pallette so that the symbols available match my list of items. I would want to base each symbol on an existing symbol.
To make it clearer, I have a treeview of named devices, and I would like to bring up the view with the pallette containing these named devices (they would all have the same shape etc...).
I think I can do it by modifying the edp file in realtime, but this is a hack solution. Does anyone know a better way.

Here is a sample that demonstrates how you can programmatically create Palette(s) and use the PalleteGroupBar/PalleteGroupView in Essential Diagram. The main points of this sample are:
- There are 2 custom symbols: MySymbol and MyOtherSymbol (refer to the MySymbol.cs file).
- There are 2 SymbolPalettes: mypalette and myotherpalette.
- Symbols are programmatically added to the palettes
- The palettes are added to the Pallettegroupbar
- Users can drag and drop symbols from the Pallettegroupbar to the Diagram
Hope this gives you an idea to implement what you are seeking.

Thanks, that worked well.
One note for VC++ developers, remember to have your PlugInClass in the format "MyDll.MyClass", not "MyDll::MyClass".
One more question, I don''t want to have a seperate model for all my elements - Is it possible to change the label that is generated depending upon which symbol is selected in the PalletteGroupBar?

You can do what you are seeking in the Model''s ChildrenChanging event as demonstrated by the following code snippet:
private void diagram1_Model_ChildrenChanging(object sender, Syncfusion.Windows.Forms.Diagram.NodeCollection.EventArgs evtArgs)
if (evtArgs.ChangeType.ToString() == "Insert")
if (evtArgs.Node.GetType() == typeof(MySymbol))
MySymbol mys = (MySymbol)evtArgs.Node;
else if(evtArgs.Node.GetType() == typeof(MyOtherSymbol))
MyOtherSymbol myos = (MyOtherSymbol)evtArgs.Node;

Hello, I'm a new developer using Syncfusion. What I'm looking for is a VB.net sample for drag and drop symbols from and to a symbol pallete. I would like to let my users to pick the symbol from a palette, to change it somehow and add the updated as a new symbol by drag and drop only. I would appreciate any help. Mayer
