ExtractValuesFromItem returns all null values

I have a hierarchical grid that uses Linq and the entity framework to do custom paging, at some point I noticed that the edit function was no longer working. The problem is that whenever I try to get the values using the following code they all come back as null.
The item.SavedOldValues is populated as I would expect. I can paste the aspx and c# but since there is ALLOT of it I figured I'd wait until someone asks for it. Right now I'm really looking for suggestions.

    
            protected void rgEditor_UpdateCommand(object source, GridCommandEventArgs e)  
        
                {  
        
                    GridEditableItem item = e.Item as GridEditableItem;  
        
                    Hashtable edited = new Hashtable();  
        
                    item.OwnerTableView.ExtractValuesFromItem(edited, item);  
        
                    //at this point edited has all the keys I would expect but the valeus are all null  
        
                }

Thanks

Custom Templates / AJAX & Customizing the prompt to delete an appointment

I am using both a custom inline insert and custom advanced edit template on my scheduler. I am making some webservice calls (custom code) in my handlers for the insert/update buttons:

protected

void rsScheduler_AppointmentUpdate(object sender, Telerik.Web.UI.AppointmentUpdateEventArgs e)

protected

void rsScheduler_AppointmentInsert(object sender, Telerik.Web.UI.SchedulerCancelEventArgs e)

All of the code works great, the scheduler is a great control and now that I am down to the polishing, I have run into two issues:

1) I cannot for the life of me get the RadLoadingPanel to fire when clicking on my Insert / Update buttons in my advanced templates. Although the code works, it leaves the user wondering what is happening as the code behind processes. When I try to add the buttons to my AjaxManager, it breaks their interaction with the scheduler so I am wondering if anyone has gotten this to work.

2) When one of my users tries to delete an appointment, the modal popup that the control throws is nice, but not applicable to my app (it is a leasing tool, not an appointment scheduler). I need to be able to modify at least the text, if not replace it entirely. Anyone know how?

Thanks,

Jim

RadPane and keyboard accessibility

I designed an application using RadSplitter with two RadPanes. The first RadPane contains a RadTreeView, is coded in the same page, works fine, and is keyboard accessible. The second RadPane pulls in another page and I cannot figure out how to shift focus using the keyboard from the RadTreeView to the updated RadPane2. The screen reader tells me that there is one frame on the page and, after clicking a link in the TreeView, that RadPane2 updated. However, none of the standard keyboard shortcuts for navigating frames and the Alt+accesskey I entered for RadPane2 doesn't work.

Is there something else I need to do to be able to move from one to the other using the keyboard?
Thanks!

[Solved] RadCalendar renders 12 pixels wider in IE 7/8 than in Firefox

Hi

Is there some trick to making RadCalendar render the same width in both IE (ver. 7 or 8) and Firefox 3.5.x.
In my case there is a 12 to 20 pixel difference i.e. wider in IE than in Firefox.

The width difference (12 to 20) depends on culture selected (Using the same browser, the Calendar does not even have the same width for all cultures).

Radwindow settings not being applied

Hello,

I am having an issue with settings for an instance of a RadWindow not being applied when the window loads.

The open event for the window works correctly:

    
                        function ShowMoveItems(met, trk)  
        
                        {  
        
                            var grid = $find("<%= RadGrid1.ClientID %>");  
        
                            window.radopen("sched_MoveScheduledMeeting.aspx?m=" + met + "&t=" + trk, "MoveMeeting");  
        
                            return false;   
        
                        }

The Control definition:

    
                <telerik:RadWindowManager ID="RadWindowManager1" runat="server" PreserveClientState="false" DestroyOnClose="true">  
        
                    <Windows>  
        
                        <telerik:RadWindow ID="MoveMeeting" runat="server"   
        
                    EnableAjaxSkinRendering="true" EnableViewState="true" Behavior="Close,Move" Skin="Web20" Modal="true" AutoSize="true" ReloadOnShow="true" />  
        
                    </Windows>  
        
                </telerik:RadWindowManager>

If i move the properties i have allocated to the RadWindowManager itself, It works.
As long as the properties are assigned to the RadWindow instance, they are not applied.

I cant seem to figure out whats going on. Could this be an Ajax thing? Do settings get overridden by usuing the Javascript Radopen command?

Any help appreciated.

Thanks.

Scheduler changes after it retrieved appointments

Hi,

I have a Scheduler on my page, which uses webservices for its data.
It starts in a TimeLineView by default, showing one day, from 8:00 - 19:30h, with timeslots of 0:30 each. Before the Scheduler calls GetAppointments in my webservice, it is shown as seen in the attached "before.png". But when GetAppointments returns its result, the Scheduler seems to redraw itself, looking like the screenshot in "after.png".
Notice the fact that the headers that should show the time show the date, and the header shows "29 oktober - 28 oktober", whilst both the begin and enddate of the current view are 29 oktober.

What can I do to solve this?
