Drag Symbol and Drop into a Pallete

Hello Mayer,

Thank you for your interest in Essential Diagram.

If your intension is to drag and drop the node from one palette to another palette, you can do this by setting the PaletteGroupView.AllowDragDrop property to true value.

Please let me know whether this is helpful to you. Also don't hesitate to contact us if you have any more questions regarding this. We will be glad to assist you.

Thanks,
Meera.

Hi Meera,
Thanks for your answer regarding the drag&drop among the palettes.
What about drag&drop a symbol from diagram to a palette?
My user creates somehow a symbol and like visio, he/she wants to drag&drop it into an open palette.

Thanks,

Mayer

Hello Mayer,

Current version does not provide support for drag and drop nodes from the diagram to the palette. I have logged feature request on this. Though we will not be able to provide the exact turnaround time, we will do our best in implementing this feature soon.

However if your intension is to add the nodes that are present in the diagram to the palette, you can easily do this by using the PaletteGroupView.Palette.AppendChild() method. I have created a sample that shows how to do this. You can get the sample from the following link - http://websamples.syncfusion.com/samples/Diagram.Windows/F61849/main.htm

Sample Details :

1. Drag and drop node from one node to the diagram.

2. Select it and click the button to add the selected node to the corresponding/desired palette.

Please let me know whether the above details are helpful to you.

Thanks,
Meera.

Hello Meera
The F6189 sample is in C#.
Do you have the F6189 sample in VB.net?
Thanks,
Mayer

Hello Mayer,

You can get the VB version of the sample from the following link - http://websamples.syncfusion.com/samples/Diagram.Windows/F61849_VB/main.htm

Thanks,

Hello Meera,
First of all, thanks for the VB sample, I'm sure it would help.
I'm apologize for asking again but I'm a new programmer in Syncfusion and I wnat to make sure I understand the following you wrote:
"Current version does not provide support for drag and drop nodes from the diagram to the palette."
Does it mean, for now it's impossible to write a code using the binary version?
If so, is it possible for me to change the Diagram view/model/controller source code (we purchased it as well)in order to enable this feature?

I'll appreciate your detailed answer and suggestions.

Mayer

Hello Mayer,

Please find my response below on your query.

"Current version does not provide support for drag and drop nodes from the diagram to the palette.

I meant that at present Essential Diagram does not provide support for drag and drop nodes from diagram to palette. This feature is yet to be implemented.

If so, is it possible for me to change the Diagram view/model/controller source code (we purchased it as well)in order to enable this feature?"
I am afraid that it is difficult to achieve/implement this feature at the application level by customizing the necessary diagram classes since it may need source code level changes, new properties/methods to be added and etc.,

Please let me know if you need any more details.

Thanks,
Meera.
