Loginview and FindControl2/14/2008 12:29:30 PM

0/0

Hi

I have a problem since I implemented a Loginview in my Master page, it seems to be causing problems with accessing controls in the content pages. I  used to change the default mode of my DetailsView control using: 

dvSoftware.DefaultMode = DetailsViewMode.Edit
But since I implemented the LoginView I am getting the error 'Object reference not set to an instance of an object'.

I read up a few posts and they mentioned about using findControl, so I did: 

Dim lv As LoginView

lv = CType(Master.FindControl("LoginView1"), LoginView)

Dim dv As DetailsView

dv = CType(lv.FindControl("dvSoftware"), DetailsView)

dv.DefaultMode = DetailsViewMode.ReadOnly
But I am still getting the same error at the  dv.DefaultMode = DetailsViewMode.ReadOnly line

 

Any ideas?

Thanks

Gary
