I use xamdatatree . when I check the parent'node,the parent's NodeCheckedChanged is invode,and his child's NodeCheckedChanged is invoke.So how can i get all the checked nodes when NodeCheckedChanged invoke? I don't want it invoke so much.
This behavior is by design, as it allows the user to react when a node's checkstate is modified.
You could set the CheckBoxSettings.CheckBoxMode to Manual and this will prevent the auto checking and auto response by the other nodes when one is checked. You would then have to change all the nodes yourself through code, but you would be able to set a flag in your application to ignore the code in your handler.
Thank you for your reply.I just change my code.I have changed all the nodes Myself through code.But the child's NodeCheckedChanged still invoke. I don't understand "set a flag in your application to ignore the code in your handler". Can Use this ignore the child'sNodeCheckedChanged?
