This problem is solved by adding a machinekey to the web.config.
Hi,
I have created 3 level hierarchial grid using datagrid control ofasp.net andasp.net ajax v1.0.
In this I have implemented custom paging with datareaders.
If my second level grid contains only one record, my thirdlevel grid paging and sorting works fine.But if my second level grid contains more than one record, my third level grid paging and sorting stops functioning
Similarly if my first level grid contains one record, paging and sorting of records in second level grid works fine. If it contains more than one record, paging and sorting of records in second level grid stops functioning.
Without AJAX, the code is working perfectly.
Can anybody out here, figure out what is the problem and help me in fixing this issue.
Thanks in Advance
Anu

I have a grid in an update panel that gets databound at runtime (to index server results). I have implemented paging and it works without atlas. As soon as I place that grid in update panel, paging stops working. All I get is a javascript error saying "line 1 :Object Requiered".
I have tried debugging it but on paging, it doesn't event get to the server.
thanks
Hi Biren,
Have you tried this with the April CTP of Atlas that was released earlier this week?
If it's still a problem, can you please provide some more details on your scenario so that we can investigate?
Thanks,
Eilon
I have done it and it works for me. Object required is a pretty generic error just as the "Object reference not set to an..." in .Net. It could be because of wrong syntax in javascript or html that you might have on the page.
If you don't mind pasting the code on the forum please do so we can look at it.
Just tried it and same error.

Hi again,
I tried this out and I'm getting the same error. This turns out to be a known bug in the April CTP of Atlas. To work around it, add this code to your Page's Load event handler:
Page.ClientScript.GetPostBackEventReference(this, String.Empty);
Thanks,
Eilon
Appears to be an issue in the June CTP too... and if it wasn't for this post, I'd still have the issue.
Thanks guys
Correct, this was not fixed in the June CTP. For now the one line workaround should still be sufficient.
Thanks,
Eilon
I have a page which contains a UserControl, which in turn contains another UserControl, which contains a GridView wrapped in an UpdatePanel. I tried adding this line to the page's Page_Load and the UserControl's Page_Load, but I get the same generic error:
Line: 10846
Char: 17
Error: Object required
FYI, the offending line appears to be the second one pasted below:
function destroyTree(element, markupContext) {
if (element.nodeType == 1) {
slp004, can you please give more details as to what you're trying to do? It sounds like other people on this thread have this scenario working so I'm curious what's going on here.
Thanks,
Eilon
I have exactly the same problem - in the same line
function destroyTree(element, markupContext) {if (element.nodeType == 1) {
My page have three or four levels of nested user controls inside the update panel. The curious thing is the page with the same controls has worked before some change I did - now I am trying to figure it out.
Wow, I figured out the issue.
The error was caused because I have another updatepanel in this page - inside a user control, included in master page. The user control has Visible=false. This scenario causes the error. When I set the user control visibility to true, the error goes off.
The solution is setting the updatepanel (that is inside the user control) mode to Conditional. This solves the problem even if the user control is invisible.
HTH.
No, images in ASp are completely different. You can use GDI+ to draw, however, but it's a bit different from winforms development. Consider the tutorial athttp://www.samspublishing.com/articles/article.asp?p=25487&seqNum=3&rl=1 as a decent place to start.
