I have an app wherein I store appointments in a DB.

I - normally - show the appointments in RadScheduler. However, there are occasions when using the scheduler is not the most appropriate too, for example, when the use queries the data base for a period covering more than 1 month.

In these cases, I use RadGrid to display the results of the query and this works just fine.

[wait for it]

But, I now have recurring appointments and these are stored using the recurrence rule in the master appointment. Is there a way for me to show the occurrences of these recurring appointments in a grid?

I can think of doing it:

Read the DB and set the DataSource of the Scheduler to the query result and then use the Scheduler's Appointments property as a DataSource for the grid.
Read the DB and set the DataSource of the Scheduler to the query result and use the AppointmentDataBound event to create a new List<> to use as the DataSource of the grid.

I haven't yet tried either of these, 'cos I'm sure I've seen an demo, or Code Library article on this very subject, but I'll be damned if I can find it.

FWIW, I prefer the idea of the 2nd of the 2 options above as the AppointmentDataBound event gices me access to the DataItem used to create the appointment in the first place, can I have a lot of extra data in that object that I would, otherwise, have to query the DB again for.

Load RadGrid using ajax request

Hello,

I have a custom ascx controls contains RadGrid and RadChart.

The control is loaded into ajax panel using ajax request

protected void RadAjaxPanel2_AjaxRequest(object sender, AjaxRequestEventArgs e) 
        { 
            if (e.Argument == "InitialLoad") 
            { 
                var auctionTotals = LoadControl("~/core/Informers/CurrencyRates.ascx"); 
                auctionTotals.ID = "CurrencyRates"; 
                panel2.Controls.Add(auctionTotals); 
              } 
        }

Inside the user control every grid row has a related chart dislayed when this row is selected.

function <%=ClientID%>_grid_OnRowSelected(sender, args) {

<%=ClientID%>_selectChart(parseInt(args._itemIndexHierarchical));

}

Here is how the event handler is added

var events = grid.ClientSettings.ClientEvents;

events.OnRowSelected = ClientID + "_grid_OnRowSelected";

Everything works just fne if the control is used on the aspx page (like a normal aspx control). But as soon as I try to load this control dynamically using ajax panel (using the first code snapshot), I get a javascript error: content_CurrencyRates_grid_OnRowSelected is not defined

I am a bit confused why the event handler is not binded to the grid in this scenario. Should this function be placed in some other part of the ascx control?

Thanks,
Andrei

HeaderContextFilterMenu For GridCheckBoxColumn

Hallo!
We have a RadGrid which displays several columns of type checkbox, bound and template columns. The header filter context menu displays two checkboxes which are present in the filter template for the checkbox column also for the columns which are not a checkbox column. (See attchment). Another problem with the header filter context menu is that for a checkbox column, the first condition filter checkbox is disabled und cannot be used as a filter. The second condition is not necessary for a checkbox column but is the only one which can be used. How can this be changed?
Solutions I am looking for:
1. Checkboxes in the filter context menu for non checkbox columns should not be shown.
2. There should be only one checkbox in the filter contet menu for a checkbox column.
warm regards

Server side OnTimeSlotClick event?

Hi,
I noticed there is a client side event called OnClientTimeSlotClick and there are few posts about how to get the time when somebody click on an empty slot on the schedule. But I really don't want to use client side event.

Is there a similar event for server side? I assume it's called OnTimeSlotClick, but I couldn't find it.

Thanks,
Dom

RadScheduler and RadTooltipManager

Hello,

Based on the sample available in the demo, I implemented a tooltip manager in my simple scheduler web page. The datas are loaded "manually" in a List and assign to RadScheduler.DataSource each time a OnNavigationCommand event occurs. The first page is loaded in Page_Load.

At the first load of the page, eveythings work fine and Tooltip load correctly through ajaxupdate. But when I use NavigationCommand, Tooltips become crazy. This is wrong Appointment Id which is return and some appointments don"t even load the tooltip.

I use the same event and same code as the example. The only difference is in NavigationCommand which loads Appointment from my Database.
here is the code after a switch which determine first and last appointment datetime:

in the class:

Dictionary<int, AppointmentInfo> m_lstAppointment;

in OnNavigationCommand event:

Session.Remove("Appointments");

SchedulerRadToolTipManager.TargetControls.Clear();

RadScheduler1.Appointments.Clear();

m_lstAppointment = m_oDataAccess.SearchAppointment(dteStart, dteEnd);

RadScheduler1.DataSource = m_lstAppointment.Values;

Yes, I tried to clean-up everything before load new appointments but with no success.
The aspx file is not far from the one provided by the telerik wizard in VS 2010, the one with AdvancedForm.

Thanks in advance for your help.
regards
Eric

RadUpload and RadProgressArea not working as expected Need Help - Urgent

Hi All,
To start with I have a page with RadUpload control alongwith RadProgressArea,one listbox and three asp buttons(Named Add to Upload,Remove Selected,Remove All.These are not link buttons but asp buttons).Once the user clicks on Add to Upload button I need to add the uploaded file into the list box.
I have the following specific requirement with regards to the RadUpload control:
File size more than 150 MB shouldnot be allowed to get uploaded (that means progress bar should not be shown when the file size is more than 150 MB and a popup message with the error should be shown)
Now I am facing the following issues:
1. Whenever I select a file and click on any of these above mentioned buttons I am getting the Progress bar which is not the expected behavior. I just want the progress bar to appear once only when Add to Upload button is clicked. I have made the property UseSubmitBehavior for all other buttons as false as mentioned in this link:http://www.telerik.com/help/aspnet-ajax/upload_howtopreventupload.html but of no use.

2.To my surprise I am also getting the progress bar if the uploaded file is more than 150 MB although I have set MaxFileSize=157286400 which means 150MB but the uploader is not uploading it instead I want to show an error message box to the user and the user shouldnot have to wait for a long time.

Please telerik support team respond me with a detailed code snippet asap since its very urgent.

Note: I cannot use jquery or RadScriptManager functions so I need to use only javascript and server side methods(I am using ASP.Net 2.0 framework)
Regards,
Shubh
