Variable 'cl' is passed by reference before it has been assigned a value for DataView Variable
I have the following code passing a dataView variable to a function and I am getting the following warning:
“Variable ‘cl’ is passed by reference before it has been assigned a value. A null reference exception could result at runtime.”

Function Editclass()
        Dim cl As DataView
        Bindclass (SqlConnection2, cl)
        Return cl
    End Function


Sub Bindclass(ByVal conn As SqlConnection, ByRef cl As DataView)
        conn.Close()
        getdata.Connection = conn
        getdata.SQL = "SELECT * FROM POM_ClassView ORDER BY CLASSID"
        getdata.FillGridDropDown()
        cl = getdata.DataView
    End Sub

How can I resolve the warning here please?
