Input string was not in a correct format.
- by Jon
I have this error which doesn't happen on my local machine but it does when the code is built by our build sever and deployed to the target server.
I can't work out what the problem is, after having spent many hours on this issue.
Here is an error trace:

And here is my code:
Trace.Warn("BindReport")
Dim sds As New SqlDataSource
sds.SelectCommand = "C_MYSTORED_PROC"
sds.ConnectionString = ConfigurationManager.ConnectionStrings("connstring").ConnectionString
sds.SelectCommandType = SqlDataSourceCommandType.StoredProcedure

sds.SelectParameters.Add(New Parameter("FROMDATE", DbType.DateTime, dpFrom.Text))
sds.SelectParameters.Add(New Parameter("TODATE", DbType.DateTime, dpTo.Text))
Trace.Warn("Parameters add ended")
Dim dv As DataView
Dim dt As DataTable
Trace.Warn("Trace 1")
dv = sds.Select(New DataSourceSelectArguments())
Trace.Warn("Trace 2")
If e IsNot Nothing Then
dv.Sort = String.Format("{0} {1}", e.SortField, e.SortDirection)
Trace.Warn("Trace 3")
Else
gvReport.CurrentSortColumnIndex = 0
gvReport.Columns(0).SortDirection = "DESC"
Trace.Warn("Trace 4")
End If
Trace.Warn("Trace 5")
dt = dv.ToTable()
Cache("NewTenancyList") = dt
Trace.Warn("Trace 6")
Trace.Warn("About to databind")
gvReport.DataSource = dt
gvReport.DataBind()
Trace.Warn("Databinded")
What I don't understand and this is really weird, why does it work on my local machine but not on the live server? If i build the code on my local machine then copy over the complete \bin directory it works. If I pull the code from source safe, build then copy, I get this error.
It seems to choke after the line "dv = sds.Select(New DataSourceSelectArguments())" in the code.
