GUID Headace

[Hennie]

I have a GridView with a uniqueidentifier as DataKey.
When the selected index change of the GridView I want to update a Session
variable with the DataKey value of the selected row. I tried
Dim ProgramID As String

ProgramID = GVProgram.SelectedValue

Session("ProgramID") = ProgramID

But get error:

Error 1 Value of type 'String' cannot be converted to 'System.Guid'.



Please help



Thanks
