Hi Ali,
Thank you for using Syncfusion Products.
FlipX and FlipY properties of Node are set to false by default.
If your intention is stop the rotate symbol that comes along with node, then you have to set can set the AllowRotate property to false.
Refer the code snippet:
Node n = this.diagram1.Model.GetChild(i);
n.FlipX = false;
n.FlipY = false;
n.EditStyle.AllowRotate = false;
Please refer the sample in the below link that illustrates the above:
