Hello,for my new application, i use this example : http://samples.infragistics.com/2008.1/webfeaturebrowser/default.htm[Grid - WebGrid] -> Editing data - Row Updating.When i wrote only one row and i submit the form, it works fine.But if i add two rows and i submit the form, i have this error :
[NullReferenceException: Object reference not set to an instance of an object.] Infragistics.WebUI.UltraWebGrid.UltraGridRow.GetRowLevel(Boolean thruGroup) +61 Infragistics.WebUI.UltraWebGrid.UltraGridLayout.System.Web.UI.IStateManager.SaveViewState() +428 Infragistics.WebUI.UltraWebGrid.UltraWebGrid.SaveViewState() +28 System.Web.UI.Control.SaveViewStateRecursive() +59 System.Web.UI.Control.SaveViewStateRecursive() +160 System.Web.UI.Control.SaveViewStateRecursive() +160 System.Web.UI.Page.SaveAllState() +466 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1676
On the demo site http://samples.infragistics.com/2008.1/webfeaturebrowser/default.htm, we have the same error.How can i solve this problem ?
Thanks.Laurent
Thanks for sharing the solution in public forums - much appreciated. I just want to tell you that NullReferenceException is a generic exception and can occur for a number of reasons. I will double check if the problem with samples (hitting Add Row twice then entering data without Primary Key causes exception) is fixed in 2008.2
A possible work around/fix has been found by using selectedRows.Clear() to wipe out any values in the selectedRows list, which is what appears to cause the problems.
I'm getting this same error when I delete a row from the underlying database during a postback event.

I was able to reproduce using his instructions. On the left hand side you can see the navigation. See error below:
