Now we have to load the whole company's organizational relationships into one
TreeView which has at lest 6~7 layer and including 300~400 nodes.In every
node,there is a checkbox.
So we need following cascade selected effect:
1. Every time we select one node,all his child nodes' state will be changed
into selected automatically(i f this node has child node).
2 . Every time we select one node,his father nodes' state will be be changed
into selected automatically.
Now we load all these nodes into TreeView in PageLoad event.And implement
the cascade selected effect above by using TreeNodeCheckCh anged event.In the
TreeNodeCheckCh anged event,we will be able to find the selected node,and then
we can find his father node and son nodes to change their state.
But now we find out that because of the number of the nodes is so big that
the treeview is very slow to loaded all the nodes.
How to speed the treeview performance?
