Hi all,
I have a designed an application in such a way that i will have a treeview initially with a Root node. If i right click on the root node i will have a context menu with the some options. By selecting an option i will add a child to that root node. Now if the tree has a child node and if i right click again i would like to display an error message as only one child allowed or some thing or i would like to disable the context menu.

Can any one help me please

Solution 1

OPTION 1:
While creating/adding a child node, disable or dont attach the right click handler to it.

OPTION 2:
Store a flag in nodes - IsChild. Based on it's value, if false, show context menu. If true, show a message or just ignore the event.

Try!

There is nothing much to provide a sample code. If you have done all what you said you already have then this is very simple and you can implement it. Try!
