VB WindowsForm Custom Class Event Handler Issue - vb.net

Question

I created a custom class (DataGroupBoxControl) that is basically a GroupBox with one or more Panels inside.
Each Panel holds two Labels side by side as pictured below.
enter image description here
The object allows a DataTable to be passed into it, which is what determines how many rows of Panels are created and displayed.
I would like the user to be able to click on one of the Panel Labels and do 'something'.
Here is the procedure inside the class that creates the Labels.
Public Class DataGroupBoxControl
Inherits GroupBox
Public DataLabels As New List(Of DataLabelControl)
Public Sub BindData(ByVal ds As DataTable)
Dim colItem As Integer = 0
For Each col As DataColumn In ds.Columns
DataLabels.Add(New DataLabelControl)
For Each row As DataRow In ds.Rows
DataLabels(colItem).TitleLabel.Text = col.ColumnName & " " & _Separator
DataLabels(colItem).TitleLabel.Name = col.ColumnName
If IsNumeric(row.Item(colItem)) Then
If row.Item(colItem).ToString.IndexOf(".") <> -1 Then
DataLabels(colItem).ValueLabel.Text = Decimal.Parse(row.Item(colItem)).ToString("c")
Else
DataLabels(colItem).ValueLabel.Text = row.Item(colItem)
End If
End If
DataLabels(colItem).ValueLabel.Name = row.Item(colItem)
DataLabels(colItem).Top = (colItem * DataLabels(colItem).Height) + 20
DataLabels(colItem).Left = 5
Me.Controls.Add(DataLabels(colItem))
Me.Height = Me.Height + DataLabels(colItem).Height
DataLabels(colItem).Show()
Next
colItem += 1
Next
End Sub
Where and how do I create a Label Click Event Handler?
And then access that event from my main form with the following object:
Public AccountsGroupBox As New DataGroupBoxControl

Answer 1

Before creating DataLabelControl use AddHandler to attach event handler eg. to TitleLabel control, then you can listen for events and raise new event that can be handled in parent control.
Public Class SomeForm
Private WithEvents AccountsGroupBox As New DataGroupBoxControl
Private Sub AccountsGroupBox_ItemClick(
sender As Object,
args As ItemClickEventArgs) Handles AccountsGroupBox.ItemClick
End Sub
End Class
Public Class ItemClickEventArgs
Inherits EventArgs
Public Property Control As Object
End Class
Public Class DataGroupBoxControl
Inherits GroupBox
Public Event ItemClick(sender As Object, args As ItemClickEventArgs)
Public DataLabels As New List(Of DataLabelControl)
Private Sub OnLabelClick(sender As Object, args As EventArgs)
RaiseEvent ItemClick(Me, New ItemClickEventArgs With {.Control = object})
End Sub
Public Sub BindData(ByVal ds As DataTable)
For Each col As DataColumn In ds.Columns
Dim control = New DataLabelControl
AddHandler control.TitleLabel.Click, AddressOf OnLabelClick
DataLabels.Add(control)
' ...
Next
End Sub
End Class
