System.ArgumentOutOfRangeException

[Matthew]

We have a RadToolTip containing a RadScheduler and two RadGrids. We want to keep these objects in sync, so we've employed a RadAjaxManager. Unfortunately, the events that we want to sync after are fired from controls within the NestedViews of the RadGrids. When EnableAjax is set to false, the following error is thrown:

Exception Details: System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
Parameter name: ItemHierarchicalIndex

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Stack Trace:

[ArgumentOutOfRangeException: Specified argument was out of the range of valid values. Parameter name: ItemHierarchicalIndex] Telerik.Web.UI.GridItemCollection.get_Item(String hierarchicalIndex) +153 Telerik.Web.UI.GridDataItemCollection.get_Item(String hierarchicalIndex) +50 Telerik.Web.UI.RadGrid.LoadClientState(Dictionary`2 clientState) +7307 Telerik.Web.UI.RadCompositeDataBoundControl.LoadPostData(String postDataKey, NameValueCollection postCollection) +305 Telerik.Web.UI.RadCompositeDataBoundControl.System.Web.UI.IPostBackDataHandler.LoadPostData(String postDataKey, NameValueCollection postCollection) +73 System.Web.UI.Page.ProcessPostData(NameValueCollection postData, Boolean fBeforeLoad) +1068 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +2773

What can we do? Thanks.

Hi,

Please refer to the following forum thread which elaborates on this matter and see if it helps to avoid this error:

I have fiddled with the settings found on thread and in a few other places. Changing the HierarchyLoadMode to be anything other than Client does indeed remove the error, but then my NestedViews don't expand and the rows in the master table start using the following row as their NestedView which creates all sorts of confusion when expanding and collapsing. Let me include on the RadGrids so you can see where I'm at.

I'm attaching before and after photos so you can see what's happening. Only row clicks occur between the two photos.

Hello,

Did you try setting HierarchyLoadMode to ServerOnDemand and what is the result?

The answer is in my previous post. We ended up switching over to panel bars.
