[Solved] Q3 2010 MasterTemplate.Refresh inside EndEdit causes exception

Hi there,

I have a gridview which i just updated to the 2010 q3 and now I am getting errors every time i try to edit a cell.
It seems that every time I call gridview.MasterTemplate.Refresh() from within the end edit handler, I get an "Object reference not set to an instance of an object" error which originates from inside telerik code.

does anyone know why this is happening?

Thanks,
Matt

problem in databinding in radscheduler

Hi

I am trying to bind my existing appointments from database to the radschedular. But it is showing only the current time's appointment which is not in the database. Eg: If I execute my code at 4.15 pm then it is creating an appointment from 4.15 pm to 4.15pm in radschedular. This appointment is not there in the database.

I have used the following code :

SchedulerBindingDataSource dataSource = new SchedulerBindingDataSource();


                AppointmentMappingInfo appointmentMappingInfo = new AppointmentMappingInfo();
                appointmentMappingInfo.Start = "FromTime";
                appointmentMappingInfo.End = "ToTime";
                appointmentMappingInfo.Summary = "Subject";

                appointmentMappingInfo.

UniqueId = "ReservationID";

                dataSource.EventProvider.Mapping = appointmentMappingInfo;
                // assign the generic List of MyAppointment as the EventProvider data source

                dataSource.EventProvider.DataSource = reservationBO.getActiveReservationsByRoom(this.RoomId).ToList();
                this.radScheduler1.DataSource = dataSource;

reservationBO.getActiveReservationsByRoom(this.RoomId).ToList(); - This is the list which I am pulling out from the database.

If I am using
this.radScheduler1.DataSource = reservationBO.getActiveReservationsByRoom(this.RoomId).ToList();
then it is showing an error message : "Cannot implicitly convert type 'System.Collections.Generic.List<RMAS.Data.Reservation>' to Telerik.WinControls.UI.SchedulerDataSource' "

how can I fix this. Need your help

[Solved] Font size varies within cell

Hello,

when i put a long text into a cell within a gridview, e.g. "aaaaaaaaaaaaaaaaaaaa", then the first part of the string has a different font size. The second part of the string appears smaller (less space between characters). How can I turn of this feature?
Is this a global setting? I think this could happen to other controls as well.

Thanks for your help

Can't launch Visual Style Builder as described in Help

I'm trying to create my own theme, specifically for the Winforms GridView. I can't even get started. I've included the first 4 instructions from the help file. I can't even get past step 2, I can't find the Visual Style Builder on the Smart Tag. Any help would be great.

From the help file.

You can customize your theme based on the built-in themes. For example, to change the color of header area, follow these steps:

Select a RadGridView control.
Start Visual Style Builder from the RadGridView Smart Tag.
Set the Theme Name to "My Theme".
In the Control Structure tab, locate and click GridHeaderCellElement.
