Hi Mounika, 

 

We have prepared a sample to update the node visible property at run time. To update the visible property of node, get the node from the node collection through the GetNode method and set visible as false. So that node does not visible in the diagram. Please find below code snippet to node visible property as false. 

 

public void OnClick() 

    { 

        DiagramNode node = diagram.GetNode("node3"); 

        // Here node3 is an Id of the node that you need to update visible property 

        node.Visible = !node.Visible; 

 

    } 

 

Solution 2: You can directly set node visible property through diagram nodes collection. Please find below code snippet 

 

diagram.Nodes[3].Visible = false; 

 

We have attached a sample for your reference. Please find the sample in below link
