While updating appointment on 'OnAppointmentCommand', throwing object reference error

Hello,

I am using rad scheduler and RadSchedulerRecurrenceEditor. While updating an appointment I am receiving 'Object null reference' error on 'OnAppointmentCommand' and not updating an appointment since appointment object is null. So currently I am creating new instance of e.Container.Appointment = new Appointment() on 'OnAppointmentCommand' and the error is temporarily removed now and updating an appointment as well.

Could you please let me know the exact solution and cause for this error.

Thanks and Regards,
Deepti

Opening the HeaderContextMenu on a Button Click

Hi folks,

I really like the show/hide columns functionality built into the context menu (EnableHeaderContextMenu). However, I can't count on users to right-click to open the menu.

To cover myself, I'd like to put a button in the command area that will open the header context menu so they can see it.

As an alternative, I'd be interested in seeing sample code to implement the show/hide column checkboxes in a regular menu or dropdown.

Thanks!

Ken

RadGrid in AjaxControlKit ModalPopup weird Filter behaviour

I have a RadGrid loaded in a dynamically created ModalPopup when doing a filter on the columns from the HeaderContextMenu
snippets shown below
AllowFilteringByColumn="True" AllowAutomaticDeletes="True" CellSpacing="0" DataSourceID="theGridViewSqlDataSource" CssClass="gridview" Width="780" AutoGenerateColumns="False" EnableHeaderContextFilterMenu="True" EnableHeaderContextMenu="True" ShowStatusBar="true"
<MasterTableView DataSourceID="theGridViewSqlDataSource" BorderStyle="Solid" Width="100%" DataKeyNames="ID" IsFilterItemExpanded="false" GridLines="Both" ShowGroupFooter="true" >

With some versions of Chrome, IE9 but not Firefox and IE8 the Filtering action invokes a full Postback. The ModalPopups are in an UpdatePanel all by themselves on the MasterPage. When using developer tools in Chrome and IE9 I can see that the Async Postback is cancelled and it is then followed by a full page postback.

All other functions on the RadGrid work as expected, paging, grouping, adding and deleting records etc.

Any ideas???

Footer columns width issue

Hello all,

I'm having an issue with the footer on a grid. We have a column that displays total information. In Firefox, the footer perfectly aligns with the column data but in IE8 (in both compatibility view and not) it's shifted to the left slightly. I used the IE Web Developer toolbar and it seems as if most of the footer columns are slightly smaller than their data column counterparts. I have attached an image that has the column highlighted to show it's positioning. It should line up perfectly with the Hours column.

Any clue how I can get this to line up properly? I am using 2009.3.1314.35.

Thanks in advance!

*edit* Sorry I realize the column headers aren't in that image. The footer should be shifted to the right slightly.

I have tried explicitly setting the FooterStyle Width property for each column but that didn't seem to help any.
