infinite do until loop within for loop in web app - asp.net

Question

So my code is going through the various components and creates bundles using the BuildKnittingRecords sub for the various components. My code works well when it creates the bundles for the Case "Sleeve", "Front", "Body", "Back" but when it gets to Case "Collar22-32" it gets stuck in the do until loop and as a result will keep on adding to PnlsToProduce(until it crashes cos the number is too big) instead of only running through the do until loop when it finds that component
Private Sub knittingdetailsheaderdataset()
bundlenum = 1
Dim SQL As String
Dim Adapter As New OleDbDataAdapter
Dim dt As New DataTable
Using con As New OleDbConnection(cnString)
Dim cmd As New OleDbCommand()
SQL = "Select bla bla
FROM bla bla
INNER Join bla bla"
(it's a very long sql statement, and not relevent to my issue)
cmd.Connection = con
cmd.CommandText = SQL
Adapter.SelectCommand = cmd
Adapter.Fill(dt)
For dr As Integer = 0 To dt.Rows.Count - 1
componentName = dt(dr)(6)
knittOrderID = dt(dr)(4)
componentID = dt(dr)(3)
sizeID = dt(dr)(5)
qtyppnl = dt(dr)(10)
Select Case componentName
Case "Sleeve", "Front", "Body", "Back"
MxBndleSz = 36
PnlsToProduce = dt(dr)(11)
BuildKnittingRecords(MxBndleSz, componentID, sizeID, PnlsToProduce, qtyppnl, knittOrderID, bundlenum)
Case "Collar22-32"
MxBndleSz = 200
PnlsToProduce = 0
Do Until componentName <> "Collar22-32" Or dr = dt.Rows.Count - 1
PnlsToProduce += dt(dr)(11)
Loop
Select Case PnlsToProduce
Case 50 To 100
PnlsToProduce = PnlsToProduce + 1
Case 101 To 250
PnlsToProduce = PnlsToProduce + 2
Case Is > 250
PnlsToProduce = PnlsToProduce + 3
End Select
BuildKnittingRecords(MxBndleSz, componentID, sizeID, PnlsToProduce, qtyppnl, knittOrderID, bundlenum)
End Select
Next
End Using
End Sub
Hence my question is, why is it doing this and how do I solve it?
This is my code for the BuildknittingRecord() sub, not sure if it's relevant in solving my issue:
Private Sub BuildKnittingRecords(ByRef MaxBundleSz As Integer, ByRef compID As Integer, ByRef sizeID As Integer, ByRef PnlsToproduce As Integer, ByRef QtyPerPanel As Integer, ByRef KnittingOrderID As Integer, ByRef bundlenum As Integer)
pnls2prod = PnlsToproduce
Dim cmdstring As String
Do Until pnls2prod < 10
If bundlenum < 10 Then
bundleNo = txtbatchno.Text & "-K0" & bundlenum
Else
bundleNo = txtbatchno.Text & "-K" & bundlenum
End If
bundlenum += 1
If pnls2prod <= MaxBundleSz Then
PanelsToMake = pnls2prod
cmdstring = " INSERT INTO [KN - KnittingDetailsHeader] (BatchNo, BundleNo, ComponentID, SizeID, PanelsToMake, QtyPerPanel, KnittingOrderID) VALUES('" & txtbatchno.Text & "', '" & bundleNo & "', " & compID & ", " & sizeID & ", " & PanelsToMake & ", " & QtyPerPanel & ", " & KnittingOrderID & ");"
Using con As New OleDbConnection(cnString)
Dim cmd As New OleDbCommand(cmdstring)
cmd.CommandType = CommandType.Text
cmd.Connection = con
cmd.Connection.Open()
cmd.ExecuteNonQuery()
End Using
Exit Do
Else
If pnls2prod < 10 Then
PanelsToMake = pnls2prod + MaxBundleSz
cmdstring = " INSERT INTO [KN - KnittingDetailsHeader] (BatchNo, BundleNo, ComponentID, SizeID, PanelsToMake, QtyPerPanel, KnittingOrderID) VALUES('" & txtbatchno.Text & "', '" & bundleNo & "', " & compID & ", " & sizeID & ", " & PanelsToMake & ", " & QtyPerPanel & ", " & KnittingOrderID & ");"
Using con As New OleDbConnection(cnString)
Dim cmd As New OleDbCommand(cmdstring)
cmd.CommandType = CommandType.Text
cmd.Connection = con
cmd.Connection.Open()
cmd.ExecuteNonQuery()
End Using
Exit Do
End If
PanelsToMake = MaxBundleSz
pnls2prod = pnls2prod - MaxBundleSz
cmdstring = " INSERT INTO [KN - KnittingDetailsHeader] (BatchNo, BundleNo, ComponentID, SizeID, PanelsToMake, QtyPerPanel, KnittingOrderID) VALUES('" & txtbatchno.Text & "', '" & bundleNo & "', " & compID & ", " & sizeID & ", " & PanelsToMake & ", " & QtyPerPanel & ", " & KnittingOrderID & ");"
Using con As New OleDbConnection(cnString)
Dim cmd As New OleDbCommand(cmdstring)
cmd.CommandType = CommandType.Text
cmd.Connection = con
cmd.Connection.Open()
cmd.ExecuteNonQuery()
End Using
End If
Loop
End Sub
