ContextMenu and TreeView in C#

Since a lot of time, I had a problem with the ContextMenuStrip on my application: when a user did a right-click on a node in one of my tree without having selected with left-click first, the node meant to be selected was not!

To fix that, just add this code on your tree “treeView1″ when the event “MouseDown” occurs:

private void treeView1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{
TreeNode tn = treeView1.GetNodeAt(e.X, e.Y);
treeView1.SelectedNode = tn;
}

Troubles are finished for my customers! (and by extension for me as well )
