I have a method in my class which returns a list of data's

Private Function GetCertificationLevels() 
            Dim theProgramYearID As Int32 = Convert.ToInt32(lstProgramYear.SelectedValue)
            Dim thePositionGroupID As Int32 = Convert.ToInt32(lstPositionGroup.Selected)
            Dim theCategoryID As Int32 = Convert.ToInt32(lstCategory.SelectedValue)
            filterLevels = _curTree.GetCertificationLevelsList(theProgramYearID, thePositionGroupID, theCategoryID)
            Return filterLevels
        End Function

filterLevels returns a count of 5 data as follows in the screenshot

I would like to retrieve the _data value only (which are 5261,5263,5262,5264 and 5260)

How to proceed?
