Question

Out of memory at line:

Asked by: reignsupreme

I have an asp.net web form with a basic drop listbox which updates a multi-select list-item box based on the selected option.  It worked fine in the initial page that I setup, but now when I copy and paste all of the code to another page, then try to select an option from the drop list, I get the error: "Out of memory at line: 139".

Both listbox/items are databound to my mssql dB and are inside an update panel.

Any suggestions?

Thanks to all the experts in advance.

did you make any changes to the collections you use.   you can get this error if the collection ie List is too large

 

by: reignsupremePosted on 2008-10-06 at 11:34:16ID: 22652964

No, all I did was a full copy and paste of the entire code.  It doesn't make any sense to me what is different between the 2 pages other than the page name.

 

by: burakiewiczPosted on 2008-10-06 at 11:44:34ID: 22653046

what is the code at 139?

 

by: burakiewiczPosted on 2008-10-06 at 11:45:14ID: 22653054

also, did any more items get added into the db?

 

by: reignsupremePosted on 2008-10-06 at 11:54:25ID: 22653140

The line is not really accurate. I have removed some lines of code and it still always says 139.  
No, nothing new has been added to the dB.  To reiterate, it works fine in the first page I created last week, but I need the functionality replicated in some other pages that have different interfaces.

Now even when I copy the exact code to a new page the error occurs.  Very strange.

 

by: prairiedogPosted on 2008-10-07 at 09:23:57ID: 22660960

Mind posting your code here?

 

by: reignsupremePosted on 2008-10-07 at 09:48:55ID: 22661208

OK, since the page contains a lot of fields and code, I tried to post just the code relevant to the question:

<form runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
       </asp:ScriptManager>
 <asp:UpdatePanel ID="UpdatePanel1" runat="server">
                                    <ContentTemplate>
                                        <asp:ListBox ID="listThera" runat="server" DataSourceID="dsTheraAreas" DataTextField="TA_NAME"
                                    DataValueField="TA_NUMBER" Width="382px" Rows="1" AppendDataBoundItems="True" AutoPostBack="True">
                                <asp:ListItem Value="0">Please Select...</asp:ListItem>
                            </asp:ListBox>
                                        <asp:ListBox ID="ListTA_SUB_1" runat="server" DataSourceID="dsSubTA_1" DataTextField="TA_SUB_NAME" DataValueField="TA_SUB_ID" Height="167px" Width="382px" SelectionMode="Multiple">
                                        </asp:ListBox>
                                    </ContentTemplate>
                                </asp:UpdatePanel>

>>>The line is not really accurate. I have removed some lines of code and it still always says 139.  

It is not refering your own code. It was likely caused by AJAX. Maybe you have a circular call that caused an infinite loop? Try lauching your application in FireFox to see if you get any JavaScript error.

 

by: reignsupremePosted on 2008-10-07 at 10:09:33ID: 22661387

OH so you were able to get the same error?
I tried it in firefox, no error, but the data does not diplay in the 2nd box.

 

by: prairiedogPosted on 2008-10-07 at 10:16:43ID: 22661454

>>>OH so you were able to get the same error?

I never had this problem before, but it seems like something crashed IE.

Open JavaScript console in FireFox to see if there is any JS error. At the right upper corner of FireFox, there is an icon for JavaScript console.

 

by: prairiedogPosted on 2008-10-07 at 10:23:47ID: 22661513

One more thing, when you copy & paste the code to another page, do the two pages in the same application? Make sure the "Inherits" in the Page directive is pointing to the right file.

 

by: reignsupremePosted on 2008-10-07 at 10:43:15ID: 22661685

I have FF 3.0.3 and do not see the JavaScript console below the Google toolbar however I found an "error console" under the "Tools" menu.

The "inherits" page directive is pointing to the right file thanks.

 

by: prairiedogPosted on 2008-10-07 at 10:47:56ID: 22661726

One thing you can try now: remove the UpdatePanel and do full postback to see if the problem still exists.

 

by: reignsupremePosted on 2008-10-07 at 11:10:08ID: 22661934

prairiedog, I think I may have found the problem.  Thanks for suggesting that I use FF's error console.  I found this in the new page's form element: onsubmit="javascript:return WebForm_OnSubmit();".   It was causing the rendered page to add the script below. The original page I developed did that contain that.  But the graphic designers took my original page and must've added it later.

Once I removed it, the AJAX section started working as it should.  

Thanks for your assistance.

<script type="text/javascript">
//<![CDATA[
function WebForm_OnSubmit() {
if (typeof(ValidatorOnSubmit) == "function" && ValidatorOnSubmit() == false) return false;
return true;
}
//]]>
</script>

Thank you, your suggestion eventually led me to look more at the javascript in the page itself and not necessarilly at the AJAX section.
