Question

I created a piece of code that will display an appropriate groupbox corresponding to the treeview node being clicked like a Preferences menu form. The code does what it’s supposed to do but my problem is figuring out how to make it so that another groubox will not be called into view if another item in the treeview is right clicked.

[Detailed]

Let’s say there are 3 nodes in the treeview. 0) General; 1) Sounds; and 2) About; If I click node [1]Sounds, it will display the appropriate groupbox, but if I right click on treeview node [0]General, it will display it’s frame and once I lift up the right click on the mouse, the focus will revert back to [1]Sounds but leave the groupbox for node 0) General. How could I failsafe this from happening?

[Code]

    private void tvFrames_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
    {
        // How would I make sure that it won't display a different groupbox if another treeview node
        // is currently being right clicked (temporarily selected before reverting back to previous focused node item)?
        if (e.Node != null)
        {
            switch (e.Node.Index)
            {
                case 0:
                    ShowGroupBox(groupboxZero);
                    break;

                case 1:
                    ShowGroupBox(groupboxOne);
                    break;

                case 2:
                    ShowGroupBox(groupboxTwo);
                    break;
            }
        }
    }

Answer 1

The best answer could be not to use treeView1_NodeMouseClick at all but stick with the standard treeView1_AfterSelect.

You also have a BeforeSelect which could be useful for Saving data or Canceling the move.
