Hi Sattar,
Thank you for your interest in Syncfusion Essential Studio.
Inorder to load a bitmap node, you need to set the PinPoint and the Size of the node you are going to add. The PinPoint should be inside the bounds of the Diagram Model and the image should not go out of the Diagram Model.
[C#]
protected void Page_Load(object sender, EventArgs e)
{
string path = @"C:\test\F69328\sunset.jpg";
BitmapNode node = new BitmapNode(path);
node.PinPoint = new System.Drawing.PointF(80, 80);
node.Size = new System.Drawing.SizeF(100, 100);
this.DiagramWebControl1.Model.AppendChild(node);
}
Please try this and let me know if this helps.
