View 1 RepliesI wrote an ASPX file in VB.NET. Originally this file ran successfully but after adding one additional parameter it now fails on "Name 'peType' is not declared". This error does not make sense to me though because I have similar parameter, 'dType', which it does not error on. What is the cause of this error?
Here is some of my ASPX code file:
Sub Page_Load(Sender as Object, E as EventArgs)
If Not IsPostback Then
Dim TheMonthDate As Date = DateAdd(DateInterval.Month, -1, Today)
calStartDate.SelectedDate = CDate((TheMonthDate.Month) & "/1/" & Year(TheMonthDate)).ToString("MM/dd/yyyy")
[Code] .....
But now my error is:
Object reference not set to an instance of an object

To declare an object in JS i can simply do the following:
var house = new Object();
house.window="square"
house.color="green"
In asp.net (VB) if i try doing the same

I have been debugging my code for a while and looking at posts in other forums, but it seems to be that everyone has a different problem than mine and what works for them will not work for me.My dropdown list is supposed to filter a gridview by choosing all the Companies that are associated to a certain product. The solution I have found online is that most people did not have DataKeyNames set in their gridview. I do have this set, but not to CompanyID. It wouldn't make any sense. So I have no idea what I am supposed to do since this is the only answer I have found.
<asp:DropDownList ID="ddlCompany" runat="server" DataSourceID="dsCompanyFilter"
DataTextField="CompanyName" DataValueField="CompanyID" AppendDataBoundItems="true"
AutoPostBack="true">
