I think the reason why I am getting this error sporadically is because I
have a parent GridView and the child formView on the same page. One
has to select a record in the GridView, then the FormView is displayed.
When a user first arrive at this page, the FormView is not drawn yet.
How can I get it to display the child formView along w/ the GridView on
the first load? It's either this workaround or I need to read in the
commandName of FormView1. I can't use ' If e.commandName = "Edit"'
in FormView1_DataBound. It doesn't like it. ;(
Maybe I can do this?
Protected Sub FormView1_DataBound(ByVal sender As Object, ByVal
e As System.EventArgs) Handles FormView1.DataBound
If FormView1.FindControl("ddlApprovers") isObject Then
*** not sure of the exact code. am still figuring it out ****
'fill in the dropdownlist
end if
Please point me to the right direction. Thanks!
