How to acces other members value asosociated with a treeView node

[Anoop]

I had created a radTree binded with sqldatabase
node creation,deletion etc are working fine
Table is like this
Table 1
CREATE TABLE [dbo].[Node0] (
[Node0ID] INT IDENTITY (1, 1) NOT NULL,
[NodeID] INT NULL,
[Node0Name] TEXT NULL,
[Node0Note] TEXT NULL,
PRIMARY KEY CLUSTERED ([Node0ID] ASC)
);

Table 2
CREATE TABLE [dbo].[Node1] (
[Node1ID] INT IDENTITY (1, 1) NOT NULL,
[Node0ID] INT NULL,
[Node1Name] TEXT NULL,
[Node1Note] TEXT NULL,
PRIMARY KEY CLUSTERED ([Node1ID] ASC)
);
Table 3
CREATE TABLE [dbo].[Node2] (
[Node2ID] INT IDENTITY (1, 1) NOT NULL,
[Node1ID] INT NULL,
[Node2Name] TEXT NULL,
[Node2Note] TEXT NULL,
PRIMARY KEY CLUSTERED ([Node2ID] ASC)
);

i want to access Node2Note (value of Node2Note for the selected node)when i clicked a node corresponding to it.Any way?
