Since you aren't using MM .NET Web Forms, the binding doesn't happen automatically. What you can do to save a call to the database is store the underlying business object DataSet in a session variable, and then restore the DataSet when you're ready to save. For example:

'' After initially retrieving the data
Session["dsSchoolCategory"] = oSchoolCategory.DataSet

'' When saving
Dim oSchoolCategory as New CategoryType
oSchoolCategory.DataSet = Session["dsSchoolCategory"]
oSchoolCategory.Entity.SetDataRow(oSchoolCategory.DataRow)
oSchoolCategory.Entity.Facility_Type = Me.txtCategoryType.Text.Trim
oSchoolCategory.Entity.Facility_Desc = Me.txtCategoryName.Text.Trim
oSchoolCategory.SaveEntity()
