Q2 2012 ExpandCollaspseColumn Error with Detail Tables

[Chameleoki]

Just upgraded my code to the lastest version and I have a detail table with the following code:

<DetailTables>
<telerik:GridTableView runat="server" DataKeyNames="JobID,JobCompleted,OrderCompleted,JobCancelled,Status" DataSourceID="dsJobs" Name="JobDetail" AllowFilteringByColumn="False" ShowHeadersWhenNoRecords="False" AllowSorting="false" ExpandCollapseColumn-Display="false">

It now gives me an error of System.NullReferenceException: Object reference not set to an instance of an object.

I tracked it down to the property of:

ExpandCollapseColumn-Display="false"

If I remove this then it works (although the expand/collapse column appears).  If I set it to ExpandCollapseColumn-Visible="false" it errors again.  It does work on the mastertableview.  I know I can hide it through CSS (but I have a mix-and-match on the same page) or codebehind, but I really don't want to update the ton of pages that this is used on.  I would rather wait for an update if this is a verified error.

Chameleoki,

I've been able to reproduce your findings using the code from the Grid / Declarative Relations online demo.

The setting works fine using the “Telerik.Web.UI.dll” 2012.1.418.40 (see image 1), but the attached error message gets thrown when upgrading to the new 2012.2.607.40 release. Plus, as you've noted, the ExpandCollapseColumn-Display="false" setting works at the MasterTableView level in both builds, but no longer works at the DetailTables levels in the newest build.

I've opened a ticket with Telerik to expedite the investigation. This thread will be updated with the findings.

Hope this help!

Thank you so much!  Nice to have verification.

After upgrading to 2012 Q2 I see a simliar error:

Object reference not set to an instance of an object. at Telerik.Web.UI.GridTableView.GetRowIndicatorColumn() at ASP.app_bookings_pages_findbookingtng_aspx._BuildControlcontrol25() at ASP.app_bookings_pages_findbookingtng_aspx.BuildControlcontrol23() at ASP.app_bookings_pages_findbookingtng_aspx.BuildControlcontrol21(GridTableView __ctrl) at ASP.app_bookings_pages_findbookingtng_aspx.BuildControlrgFindBooking() at ASP.app_bookings_pages_findbookingtng_aspx.BuildControlContent2(Control __ctrl) at

But in my case I already have ExpandCollapseColumn visible.  Here's the code where it errors:

<MasterTableView DataKeyNames="RoomBookingID" AllowPaging="True" PageSize="10">
    <DetailTables>
        <telerik:GridTableView DataKeyNames="RoomEventID" Name="Event" meta:resourcekey="GridTableViewResource2">
            <DetailTables>
                <telerik:GridTableView Name="Serv" meta:resourcekey="GridTableViewResource1">

The error disappears if I remove both the meta:resourcekey attributes:

<MasterTableView DataKeyNames="RoomBookingID" AllowPaging="True" PageSize="10">
    <DetailTables>
        <telerik:GridTableView DataKeyNames="RoomEventID" Name="Event">
            <DetailTables>
                <telerik:GridTableView Name="Serv">

Is this the same error in a different guise, or a different problem?

Hi Cameron,

You need to upgrade to the latest internal build of the Q2 2012 release. It has not yet been uploaded but will be out by the middle of the day tomorrow (Easter European Time). Please, download it and upgrade your project.

All the best,

Hi Tsvetoslav

Will the new release also solve my issue?

If so, are there many other changes in this release?  We're quite close to a release ourselves and so want to avoid too much disturbance.

Hi Robert,

Yes, the latest build of the Q2 2012 release should solve your problem as well.
