Hello everyone, I have a webgrid that sits in a warp to handle the postbacks generated by an ultraClacManager attached to the grid. This combination of controls causes a memory leak in IE, IE consumes about 1000 - 2000k per trapped postback and grows without limit. This has been identified originally as a bug by Infragistics as BR26172. My Question to anybody that has run into this problem is; have you found a work around short of removing the warp and asynchronous postbacks? I have tried wrapping the grid in an ASP.NET UpdatePanel however the Ajax extensions seem to be incompatible with the infragistics controls. This bug has delayed the move to production for 2 months now and we all know this is not good. Any help or incite would be greatly appreciated. Thanks in advance,Patrick
Memory leaks are usually caused by object closures or event handlers that were never detached. The process of detaching the grid happens through a javascript function - igtbl_unloadGrid(gridName,isSelf) Many times when AJAX is involved, detaching previous event handlers is a delicate matter. First check and make sure you're not manually adding any event handlers (to html elements) or creating any closures. If you have client-side event handlers defined for the grid, try removing them and testing the affect on memory to see if they're contributing.
NetAdvantage for ASP.NET should work with ASP.NET AJAX Extensions, so any issues you find with that respect should also be submitted to our support department as a bug.
