Warning on Node.Parent and .Index

[Gourangi]

Hi,

i am getting warning while accessing RadTreeNode's Parent and Index property that it is obsolete.

Can i have some replacement for this so those warning be removed ?

Thanks

Hello Divyesh,

These properties are marked as obsolete because the setters of the Parent and Index properties will be removed. However, the getters will not be removed and you still will be able to get the needed value.

In case you are using the setters of these properties, here is how you should modify your code:

1. Instead of radTreeNode2.Parent = radTreeNode1, you should add radTreeNode2 in the Nodes collection of radTreeNode1 using the Add method. Supposing that radTreeNode1 is the first node in the RadTreeNode.Nodes collection (i.e. with Index 0), the code is:

   this.radTreeView1.Nodes[0].Nodes.Add(radTreeNode2);

2. Instead of using radTreeNode2.Index = 1, you should insert the node in the Nodes collection (using the Insert method) and give the appropriate index:

   this.radTreeView1.Nodes.Insert(1, radTreeNode2);

If you have additional questions, do not hesitate to contact me.

Hello Divyesh,

The warning for the Index property will be removed once the setter of this property is removed. This will be addressed in one of our next versions.

If you have additional questions, feel free to contact me.

So just to be clear in the future this will work?

 

Dim node As RadTreeNode

 

node =

New RadTreeNode("Profile")

 

tvTreeView.Nodes.Add(node)

 

node = New RadTreeNode("Publications")

 

tvTreeView.Nodes.Add(node)

 

node = New RadTreeNode("New Publication")

 

tvTreeView.Nodes(

"Publications").Nodes.Add(node)

 

tvTreeView.ExpandAll()

Hello William,

Correct. This code snippet will work in our future versions and you should have no worries about it. If you have additional questions, feel free to contact me further.
