Hi,

I am struggling with the following and hope someone out there can help. I am binding to a scheduler based on a RadComboBox selection. Error handling is in place, so that if there is no schedule data, we set the datasource for our scheduler to an empty dataset from the following function

Function EmptySchedulerDataTable() As DataTable
        Dim tbl As New DataTable

        tbl.Columns.Add(New Data.DataColumn("PresentationID"))
        tbl.Columns.Add(New Data.DataColumn("PresentationName"))
        tbl.Columns.Add(New Data.DataColumn("StartTime"))
        tbl.Columns.Add(New Data.DataColumn("EndTime"))
        Dim rw As Data.DataRow
        rw = tbl.NewRow()
        rw("PresentationID") = 1
        rw("PresentationName") = "No Agenda Available"
        rw("StartTime") = Date.Now
        rw("EndTime") = Date.Now.AddDays(1)
        tbl.Rows.Add(rw)
        Return tbl
    End Function

Unfortunately, I am getting an error that I have not seen before (just upgraded to q1 2009) as follows

System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.ArgumentOutOfRangeException: The added or subtracted value results in an un-representable DateTime.

What are we doing wrong here? thanks.
