TreeNode::Toggle Method ()
.NET Framework (current version)
Toggles the tree node to either the expanded or collapsed state.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The tree node is toggled to the state opposite its current state, either expanded or collapsed.
The following code example removes a TreeNode when the user right-clicks the mouse over it and toggles it from expanded to collapsed when the user clicks the mouse wheel over it. This example requires that you have a Form with a TreeView control on it. The TreeView should have two or more root tree nodes, each having at least one child node.
private: void treeView1_MouseDown( Object^ /*sender*/, MouseEventArgs^ e ) { switch ( e->Button ) { // Remove the TreeNode under the mouse cursor // if the right mouse button was clicked. case ::MouseButtons::Right: treeView1->GetNodeAt( e->X, e->Y )->Remove(); break; // Toggle the TreeNode under the mouse cursor // if the middle mouse button (mouse wheel) was clicked. case ::MouseButtons::Middle: treeView1->GetNodeAt( e->X, e->Y )->Toggle(); break; } }
