diagram's move node method

[mohammad]

Hi
I'm using syncfusion v:20.4.0.44 / visual studio 2022 / .Net 6

When a node drops on the diagram it will move to specific coordinates
The problem is when it moves a shade of node remains in the drop area until a click or scroll happens then the shade disappears!!!
for example :
node drops in point a and then moves to B. But a shade of node remains in A (dropped area)

I use this code to Move added node:

{

var dyCoordinate = -(addedNode.PinPoint.Y - BaseYLine);

var nodeColl = new NodeCollection {addedNode};

diagram.MoveNodes(nodeColl, 0.0F, dyCoordinate, MeasureUnits.Pixel);

}

I don't want to display this shade !

2- there is something that I don't understand is :
 move Node method returns False But the node Moves correctly to the location I want.
I don't get why this returns False.

Thanks.
Best Regards

Hi Karkuvel
thanks for your reply

I modified the sample you sent, But I did not get the shades problem !!!
I upload my code to see If you can help me out

New Edition :
I've found the cause of shades problem:
diagram.Focus():  is the reason . 

I don't know why this was a problem

Hi Mohammad,

We have validated the provided sample and found that the issue can be replicated when the diagram.Focus() method is added, as reported. By default, the diagram will automatically be brought into focus when an item is added to the diagram by drag and dropping it from the palette. Could you please share us the purpose of adding this method explicitly in NodeCollectionChanging event?
