Context Menu

[mrs]

I am trying to display a different context menu for different tree nodes. I can distinguish what node has been selected but the context menu is displaying the context menu for the last node selected. After searching the forums I saw that you have to place:

treeView1.SelectedNode = treeView1.GetNodeAt(e.X, e.Y);

in the mousedown event. I still have the same result. I stepped through the mouse down code to ensure it is working and it is.

*********************
On mouse up I verify the right mouse button:
*********************

if(e.Button == MouseButtons.Right)
{

*********************
I then see what type of node by checking the .Tag property:
*********************

TreeNodeTypeStruct newTreeNodeTypeStruct = new TreeNodeTypeStruct();

newTreeNodeTypeStruct = (TreeNodeTypeStruct) treeView1.SelectedNode.Tag;

if(newTreeNodeTypeStruct.getTreeNodeTypeStruct() == TreeNodeType.System)
{

*********************
I create the context menu:
*********************

MenuItem miAddZone = new MenuItem("Add Zone",
new EventHandler(OnAddZoneNode));

cm1.MenuItems.Add(miAddZone);

//EventHandler ehAddZone = new EventHandler (OnAddZoneNode);
//cm1.MenuItems.Add("Add Zone", ehAddZone);
ContextMenu = cm1;


*********************
The event method:
*********************


void OnAddZoneNode(object obj, EventArgs ea)
{
TreeNode newNode = treeView1.SelectedNode.Nodes.Add("Zone");
TreeNodeTypeStruct myTreeNodeTypeStruct = new TreeNodeTypeStruct(TreeNodeType.Zone);
newNode.Tag = myTreeNodeTypeStruct;
}



*********************
During debug the functions are stepping through but the wrong menu is being displayed.

Any advice??

Greetings,

I was able to work around that problem by showing the context menu manually, thus not setting the tree view's ContextMenu property.

TreeNode node = treeView1.GetNodeAt(e.X, e.Y);
if (node != null)
{
    MenuItem item = new MenuItem(node.FullPath);
    cm1.MenuItems.Clear();
    cm1.MenuItems.Add(item);
    cm1.Show(treeView1, new Point(e.X, e.Y));
}
