[Solved] RadGrid Filtering Issue

[Brenda]

Hi,
I am running a site with DotNetNuke 4.5.1
I have have a page with four RadGrid with Column Filtering Enabled.
Each grid has one ClientSelection field and One GridBound field (String).

I have set the following properties for all the 4 grids:

CurrentFilterFunction="Contains"
AutoPostBackOnFilter="true"

I have removed all the FilterFunction in the Grid's Init event:
GridFilterMenu filterMenu = RadGrid1.FilterMenu;
filterMenu.Items.Clear();

Also have AJAX manager on the page with Grid's as the Target control to handle partial rendering on

When I use the filtering option in IE6 and IE7 by pressing Enter/Clicking on the FilterImage, it works a few times then starts giving this following error:
"this.get_element().parentNode is null or not an object".

The errors are intermittent, no fixed reproduction path.

I am not using any TreeView or other controls with contextmenu except for these 4 grids.

There are no errors in FireFox 2.0.

I am using Telerik.Web.UI.dll version (2008.1.415.20) (Evaluation) Version.

Any help in this matter is appreciated.

Hi,
The issue was solved by removing all the radgrids from the AjaxManager settings.
UpdatedControls collection.
Because the controls are place in a DotNetNuke module, the AJAX handling of DNN interferes with AjaxManager. We deduced this creating small test cases in and out of DNN environment.

Please let me know if you know of the above issue.

Thanks for your help.
