another child

Dim myconn As New Data.SqlClient.SqlConnection
Dim mycommand As New Data.SqlClient.SqlCommand

myconn.ConnectionString =
ConfigurationManager.ConnectionStrings("TrainUserConnectionString").ConnectionString
myconn.Open()

Dim daClassifications As New Data.SqlClient.SqlDataAdapter
Dim sqlcom As New Data.SqlClient.SqlCommand

daClassifications.SelectCommand = sqlcom
Dim sqlcom1 As New Data.SqlClient.SqlCommand

Dim daTitle As New Data.SqlClient.SqlDataAdapter

Dim dsFaq As New dsFaw
daclassifications.Fill(dsFaq, "Classifications")
daTitle.Fill(dsFaq, "Title")


dsFaq.Relations.Add("TopToQues",
dsFaq.Tables("Classifications").Columns("ClassificationID"),
dsFaq.Tables("Title").Columns("classificationid"))
Dim nodeTop, nodeQues, nodeAns As TreeNode

Dim rowTop, rowQues As DataRow

For Each rowTop In dsFaq.Tables("classifications").Rows

nodeTop = New TreeNode

nodeTop.Text = rowTop("description")

TreeView1.Nodes.Add(nodeTop)

For Each rowQues In rowTop.GetChildRows("TopToQues")

nodeQues = New TreeNode

nodeQues.Text = rowQues("Title")

nodeTop.ChildNodes.Add(nodeQues)

nodeAns = New TreeNode

nodeAns.Text = rowQues("description")

nodeQues.ChildNodes.Add(nodeAns)

Next
