Question

I have a DetailsView, I need get the value specifield in DataKeyNames “UserId” (a Guid Field) and add it to an Object Guid.

At the moment I am using this code:

String myUserId = (String)uxAuthorListDetailsView.DataKey["UserId"].ToString();

but I would need something like:

Guid myUserGuid = (Guid)uxAuthorListDetailsView.DataKey["UserId"].ToString();

But does not work I get error Error

Cannot convert type 'string' to 'System.Guid'

What could be the problem? Thanks guys for your support!

Answer 1

Check under debug: what object is uxAuthorListDetailsView.DataKey[“UserId”]
I guess this must be already the Guid; and conversion is not needed
