  Hello,
  
  I am using C1 Treeview in my project.

  Is there any way to select a node on Mouse Right Click? Actually I am invoking Context Menu on Right Click but before that it should select the node first and then invoke Context Menu.

  Hi,
  
  Try to use the below code in MouseRightButtonDown event;

          private void C1TreeView_MouseRightButtonDown(object sender, MouseButtonEventArgs e)
          {           
              Point p = e.GetPosition(treeview);
              var ControlType = treeview.InputHitTest(p);
              if (!(ControlType is Border))
              {
                  var node = treeview.GetNode(p);
                  node.IsSelected = true;
              }
          }
  

  Hope, it will solve your issue.

  Thanks,

  Thank you for your valuable response.

  Is there any alternate way to do this and stick with MVVM Pattern? Event Trigger? Or anything else?

  Hi,
  
  You can set you MVVM property in MouseRightButtonDown event as below:

  private void C1TreeView_MouseRightButtonDown(object sender, MouseButtonEventArgs e)
          {           
              Point p = e.GetPosition(treeview);
              var ControlType = treeview.InputHitTest(p);
              if (!(ControlType is Border))
              {
                  var node = treeview.GetNode(p);
                  node.IsSelected = true;
                  dataitems.MySelectedItem = node.DataContext as Item;   // Set MVVM property here
              }
          }
  

  Also, find a sample application attached.
  
  Note: You can modify attached sample accordingly.

  Thanks,
