Drag and drop

[Sl1ver]

anyone know where i can get help on making objects within the database(displa ys in tree view) able to be dragged and dropped in new locations? e.g. drag location A from house A to House C?

Are you assigning your object to the .Tag property of the treeView node?

I would guess it to be something to the effect of using that Node.Tag object as the object of the D-n-D

here is some sample coding
tvLocations.Sel ectedNode.Tag.T oString()
any idea on how to make them able to change position withtin the tree view? obviously this change would be applied to database

Nodes only understand .Add and .Remove
You would have to take the currently selected node...
.Remove it from the node it belongs to, and
.Add it to the node you want it on


Here is how I determine a node based on mouse arguments so I can do a right-click which treeview's don't support in their events.

        private void treeView1_MouseDown(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Right)
            {
                TreeNode selectedNode = treeView1.GetNodeAt(e.X, e.Y);
                        //MessageBox.Show("You clicked on node: " + selectedNode.Text);
                }
               //else we ignore it for convenience
            }
        }

You should be able to tear this apart to work out the node selected at mouse down, and again at mouse up
