Hi Guys,
I am doing some work with a treenode and I want to record the
selected item, and it may change while the user is performing some
tasks and I need to know which one was originally selected.
I want to create a property which will store the selected
TreeNode, and I can refer back to that when it is time to make the
changes. However I get a stack overflow error when I assign to the
propery. Here's the code

private TreeNode OperationNode
{
get
{
return OperationNode;
}
set
{
OperationNode = value;
}
}

I try to assign using OperationNode = TreeView.SelectedNode, and the
stack overflows. Any idea would be appreciated. I have used properties
with strings and int's no problem before but this is the first time I
am using them with a complex type. I'm not sure if I have to create a
new object somewhere, I was playing with Clone, but that creates a
different object to the one i want. I supposed I could clone and then
go through the tree and use the object.Equals function, but there must
be an easier way than that.....

Cheers,

JD

You need to use an actual variable within your get { } and your set { },
instead of OperationNode. What you're doing here is using the same
property from within the property.
 
small typo

it should be:

private TreeNode operationNode = null;

private TreeNode OperationNode
{
get {return operationNode;}
set {operationNode = value;}
}

using OperationNode will just call the property which will cause a stack overflow.
