Hi,
We are using Infragistics4.Web.v14.1 and implemented the WebHierarchicalDataGrid in our project.We have upgraded the version of infragistics from 14.1 to 17.1. In our application we are using FilterType as ExcelStyleFilter. But its not working in newer version(v17.1).
we are getting following errors in browser
[NullReferenceException: Object reference not set to an instance of an object.]Infragistics.Web.UI.GridControls.Filtering.SaveViewState() +1000Infragistics.Web.UI.Framework.ObjectBase.System.Web.UI.IStateManager.SaveViewState() +38Infragistics.Web.UI.Framework.ObjectCollection.SaveViewStateItems() +204Infragistics.Web.UI.Framework.ObjectCollection.SaveViewState() +92Infragistics.Web.UI.Framework.ObjectCollection.System.Web.UI.IStateManager.SaveViewState() +38Infragistics.Web.UI.GridControls.WebDataGrid.SaveViewState() +346Infragistics.Web.UI.GridControls.ContainerGrid.SaveViewState() +288Infragistics.Web.UI.GridControls.ContainerGrid.System.Web.UI.IStateManager.SaveViewState() +38Infragistics.Web.UI.GridControls.WebHierarchicalDataGrid.SaveViewState() +570System.Web.UI.Control.SaveViewStateRecursive(ViewStateMode inheritedMode) +93System.Web.UI.Control.SaveViewStateRecursive(ViewStateMode inheritedMode) +319System.Web.UI.Control.SaveViewStateRecursive(ViewStateMode inheritedMode) +319System.Web.UI.Control.SaveViewStateRecursive(ViewStateMode inheritedMode) +319System.Web.UI.Control.SaveViewStateRecursive(ViewStateMode inheritedMode) +319System.Web.UI.Control.SaveViewStateRecursive(ViewStateMode inheritedMode) +319System.Web.UI.Control.SaveViewStateRecursive(ViewStateMode inheritedMode) +319System.Web.UI.Page.SaveAllState() +530System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1225
Hello,
Thank you for contacting Infragistics!
I create a sample to test this and I have been unable to reproduce the behavior you describe. The best way for us to assist you is if you provide a small isolated sample that we can run and use for debugging locally. If you are unable able to provide an isolated sample I may be able to give suggestions if you provide the code for your page.
Hi, Here we attaching our isolated sample.If we put filter type as 'excelstylefilter',error should happened in infragistics version 17.1.But if we put 'rowfilter' instead of 'excelstylefilter',the solution will run.But we want excelstylefilter in our project.Also there is one more issue, the datetimefield is not filtering. Please check this.
Hello Lithin mohan,
I am assisting with this issue since Mike P. is out of the office.
Thank you for the sample! I am able to reproduce both issues using your sample with Infragistics version 17.1.20171.1001.
I could not find any existing issues addressing the NullReferenceException, but I also tested this with our latest builds and I am not able to reproduce it in our newer internal builds.
I tested our latest bi-weekly build and also could not reproduce the NullReferenceException, so I recommend installing this bi-weekly release to resolve this issue.
If you are still experiencing the issue after installing this version, please let us know.
As for the DateTime field not filtering correctly, I will need more time to look into why this is happening. I will have another update on my findings for you tomorrow.
I have created a support case for you with an ID of CAS-187329-G9M0T8. The matter has been determined to be a development issue and has been logged in our tracking system with ID: 243314.
