Dim Counter As Integer = 0 

For Each row As DataRow In m_TableCheckTypes.Rows 
rdo = New System.Windows.Forms.RadioButton 
rdo.Name = "rdo" & Counter + 1 
rdo.Appearance = System.Windows.Forms.Appearance.Button 
rdo.Size = New Size(25, 25) 
rdo.Location = New Point(2, 8 + (Counter * 24)) 
rdo.TextAlign = System.Drawing.ContentAlignment.MiddleCenter 
rdo.UseVisualStyleBackColor = True 
rdo.Text = row("CheckTypeCode")
 rdo.Tag = row("CheckTypeID")
 AddHandler rdo.CheckedChanged, AddressOf rdo_CheckedChanged
