Unfortunately, no.

The only hope at this time is a workaround. I did not know a version / release of WebGrid that does not contain such a Killerbug. So a rollback is not possible.

 I' ve tried to reproduce the problem in a new project to send to support. Without success so far. It must be a special condition.

pellcomp?

Hello,

So if it is a special condition and you are able to see it in your project, then can you please try to simulate it as closest to your project as possible? What else is on the page -- are there any other 3rd party controls, are there any AJAX enablers like UpdatePanel, WebAsyncRefreshPanel, etc?

Hi, no. No Panels.

We use build in ajax functionality of the WebGrid.

Here' s so far what i' ve tried to make a new project closest as possible.I believe it has something to do with the pager.

We load griddata via grd.invokeXmlHttpRequest(grd.eReqType.Refresh);

The original project is a little more complicated. So I guess i' ve to figure it out.

Hope this helps...

Thanks for the follow-up. While I will do my best at my side to continue working on this item and to reproduce the issue, I still believe the best / fastest and most reliable way to solve this is to contact Developer Support directly at:

http://ko.infragistics.com/Support/#Overview

It is just the problems like that are typically hard to resolve over peer-to-peer forums.

Thanks.

Hi again,

I cannot reproduce so far, but the problem is in the Javascript function

function igtbl_editList(g,v,r,col,cElem) in Line 764;

In the working testproject the variable g.IsXHTML is true.In the not working Project it is false.

So if g.IsXHTML is false cStyle will never be initialised.

What is g.IsXHTML?

How to set this value to true?

Are there changes in behavior to previous versions?

Please download and install v 8.3.20083.2059. This issue is fixed there.

Any other solution?

I have the same error in ultrawebgrids with columns of columntype "DropDownList" after upgrading to Version 8.3.20083.2039. It seems that on any upgrading i have new problems/bugs in my pages with infragistics controls :-((

This checks if the document is a xhtml file.
You can simply add the xhtml DOCTYPE declaration to avoid the error.

Thank you for your suggestion.  Just adding the DOCTYPE to the master page (it was in one, but missing from another) solved the issue for us.

DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

Hi mroyalty2002,

so it seems the forum is today available.

I put the code into Page_InitComplete.

Hi svsde,

Where would you add this code at?  Would it be in the pages load or prerender event?  I added it to the prerender but that is causing an object reference error.

 Thanks for the help.
