Why new node is regenerated upon button click?

Question

Hi,I am new and still exploring how to use the diagram best for my current project.I have created a simple diagramwebcontrol with a node and a button.What I did is, load the page and try to drag the node around and click the button to retrieve the node properties, such as x and y location. But I noticed, upon button clicked, new node will be generated based on how many times I drag the previous node.What can I do to prevent this happen? All I wanted to do is, to load the diagramwebcontrol with only one node.Hope to hear from Syncfusion soon.WebApplication1_19a973a3.zip

Hi Jitul Chanar,Thank you for using syncfusion products. I noticed that in you sample everytime when postback happens new node is created. So only when you are clicking on the button two nodes are created in the diagram.I modified you sample by checking for an Ispostback and added the nodes in the pageload.
