Change Label text inside ListView with Findcontrol Method

Hi,

I'm trying to change the Text value of a Label inside a ListView Item.

I use this code (as someone mentioned that it works...) but still it won't change the text:
Dim mylabel As Label
mylabel = CType(ListView1.Items(selected).FindControl("_sendStatus"), Label)
mylabel.Text = "Problem" Any Ideas? Thanks. ...
