The application I'm working on is writing to 2 different tables. The
first table is the ProjectName, ID (AutoNumber), and the Date/Time
added as a timestamp. The next table, writes all the components of that
project, ItemName, Creator, etc... One of the fields in this table is
ProjID and ID (Autonumber). ProjID is retrieved from a function for
grabbing the MaxOfID in the first table that is equal to ProjectName
and the date/time. I performed an executescalar to retrieve this
integer and set Viewstate("ID") = objCommand.ExecuteScalar
The problem is that when I set intID = Viewstate("ID") a value of 0 is
returned. What could cause this viewstate disappearance? 7 1248
You need to add your variable first.
viewstate.Add("ID", 0)

Thanks for the tip Landers. I am sorry to say that I am still getting 0
returned.

Function 1 (byval x ...)
Fill dataset here (ds, "DataTable")
Dim intID as integer = ds.Tables("DataTable").Rows(0)("ID")
Response.Write("intID = " & intID & "<br>") 'to test -> works
Viewstate.Add("ID", Cint(intID))
Response.Write("intIDVS = " & Viewstate("ID") & "<br>") 'to test
viewstate value -> works
End Function
Sub btnRelease (...)
Dim intID as integer = Cint(Viewstate("ID"))
Response.Write("intIDTest = " & intID) 'to test calling viewstate
value -> doesn't work
End Sub
ok, and where it is in page lifecycle?

I posted that I fixed this yesterday and it didn't update. Anyway,
thanks for the help Joe. I was writing to the viewstate after my
datagrid was bound. This caused a value of 0. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |
