make sure the id "kch" is correct, and you have set runat="server" on the label Dim a As Label
a = CType(e.Item.FindControl("kch"), Label)
if not (a is nothing) then
Response.Write(a.Text)
else
Response.Write("how could it be null?!<BR>")
end if
a = CType(e.Item.FindControl("kch"), Label)
if not (a is nothing) then
Response.Write(a.Text)

Response.Write("how could it be null?!<BR>")
end if
