Hi,

I'm missing the opportunity to zoom in by double clicking on the map. Is there a way to detect a double click in the client?

Kind regards

null reference error when adding KendoEvent.RecurrenceException to iCal.ExceptionDates

I need to take a recurring event that was set up in the kendo scheduler and unpack it so i can get an entry for each date. I am using iCal.Net to do this.

It works as expected for recurring events, but when i delete an occurrence from the recurring event and try to pass kendoEvent.RecurrenceException to iCalEvent.ExceptionDates.Add(new PeriodList(kendoEvent.RecurrenceException) I get a null reference exception when i call iCal-Calendar.GetOccurrences.

Do I need to do something when converting between kendo and ical?

TIA

My code is:

public static List<Occurrence> UnpackRecurrence(ISchedulerEvent scheduleEvent, DateTime? start = null, DateTime? end = null)

{

List<Occurrence> rVal = new List<Occurrence>();

if (string.IsNullOrWhiteSpace(scheduleEvent.RecurrenceRule) == false)

{

var recurrencePattern = new RecurrencePattern(scheduleEvent.RecurrenceRule);

iCalendar calendar = new iCalendar();

Event evnt = new Event()

{

Start = new iCalDateTime(scheduleEvent.Start),

End = new iCalDateTime(scheduleEvent.End)

};

evnt.RecurrenceRules.Add(recurrencePattern);

if (string.IsNullOrWhiteSpace(scheduleEvent.RecurrenceException) == false)

{

evnt.ExceptionDates.Add(new PeriodList(scheduleEvent.RecurrenceException));

}

calendar.Events.Add(evnt);

start = start ?? scheduleEvent.Start;

if (end == null)

{

if (recurrencePattern.Until != DateTime.MinValue)

{

end = recurrencePattern.Until;

}

else if (recurrencePattern.Count > 0)

{

end = DateTime.Now.AddYears(recurrencePattern.Count);

}

else

{

end = DateTime.Now.AddYears(5); // we probably shouldn't hit this

}

rVal = calendar.GetOccurrences(new iCalDateTime(start.Value), new iCalDateTime(end.Value)).ToList();

}

return rVal;

}

getting the RadGrid checkbox column value in server

HI,

I have a RadGrid having a checkbox column, i have added the column as a ItemTemplate to make it editable in the regular mode.

<telerik:GridTemplateColumn UniqueName="IsSelected" DataField="IsSelected">

<ItemTemplate>

<asp:CheckBox ID="chkBoolean" runat="server" Checked='<%# Convert.ToBoolean(Eval("IsSelected")) %>'

Enabled='<%# Convert.ToBoolean(Eval("IsSelectionDisable")) %>' />

</ItemTemplate>

</telerik:GridTemplateColumn>

Using this I am able to display a checkbox as editable. Now my problem is how do i get the checked value of the checkox for saving it when the user has changed the checkbox. On click of a button i need to get all the rows that are still checked and save them.

Thanks
Arvind

radeditor not generate its own html

When looking at the Telerik website forums called UI for ASP.NEXT Ajax I have the following questions:
1. it looks like you have an option to have html generated by an asp.net form can either edit your applications' html or not.To be able to have your html edited or not would you show me/tell me how to to set this up? **I would assume this is a web.config file setting
2. Does the radedior generate its own html? IF so, does the radeditor generate the html to fix html errors? If so how can you have the radeditor not generate its own html?
