I have a rad grid with check boxes.
I have a rad combo box that controls what data is returned to the grid.
I have a button that processes the checked items.
The first time the data is loaded, selected items are present and processed.
If I change the combo box selection, the data loaded is correct but the selected items always returns an empty list.

Hello All,
In searching the various Telerik webpages outthere I found:
http://www.telerik.com/help/aspnet-ajax/grid-updating-inplace-and-editforms.html , that has examples on how to use the builtin edit form to edit a row in the grid...  I've tried to get my code as close as possible, but I'm not getting very far.  When it gets to the line:
It give me an error of "NullReferenceException occurred"

Here is my page and the code behind as well:

and here is my code behind for the update event:

OK all,  Any Ideas as to what the heck I'm doing wrong????  
as a caveat, I'm a total "Newbie" at the telerik controls, and it's been a long time since I've done any ASP programming, like back before ASP.Net, yes back in the classic days...

Thanks in advance,

Any ETA when the other 30 controls will be included in the Visual Style Builder?

I am going to use Radscheduler for the first time.Basically I need to customize my insert/edit window,do some programming in the code behind while inserting/updating(using sql datasource) an appointment.Also I need to have additional buttons and textbox controls in the insert/edit window.I have gone through all the demos and understood direct insert/update/delete from the markup using sql datasource.But for the server side programming,I am totally confused with the demos and tutorials .
I need to know if I can handle the scheduler also in the same manner as other telerik controls like radgrid and use the server side events as for a normal aspx page for the insert/edit form.

I need to do the insert/update in the code behind.Before inserting I need to calculate the appointment number,also need to fetch registration id from the another table.While insert in appointment table,I need to check if appointment exist  at that time of the day.If yes,need to show error message and save should not happen.

I am totally confused as how to do the save process in the code behind instead of using  <InsertParameters> / <UpdateParameters> in the markup and using below code in the code behind.

protected void RadScheduler1_AppointmentInsert(object sender, SchedulerCancelEventArgs e)
{
  Appointments.Add(new AppointmentInfo(e.Appointment));
}
Can I do the above process in a buttonclick event where I can do all the calculations,insert/update the database
 and bind the scheduler?
Also,If I am customizing the popup window/Insert form,do I need to do as in 
http://demos.telerik.com/aspnet-ajax/scheduler/examples/advancedformtemplate/defaultcs.aspx in order to have the recurrence 
reminder or should I use a raddock for the same ?

Please guide me on this asap.Sample code for the same if any,would be highly appreciable.
Thanks,
Soumya.

I would like to upload the selected files directly to the server without requiring the user to make a postback. The client side file upload should be followed by upload to server automatically. Also I dont want to use a Generic handler. How can I accomplish this?

Any input appreciated

Hi

Just thinking out loud here, I have a radComboBox with a tree view inside, We have to add another selection criteria on an already busy form, I'm wondering if its possible to put a few (only 3-4) checkboxes above the tree view all enclosed in a RadCombobox. The tree view would be populated based on which check box was selected.

Hi, I have a performance problem whit multicell selection in ie8... It is very slow, furthermore if a cell contains a radtexbox The application gets frozen when i focus it. However The problem disappears in IE10 or if i don't set The selection mode. Thanks

If the width of some dropdown menu items exceed the width of RadCombox, how to expand dropdown menu in that case all menu items will be shown?

Hi Experts,

From client code, is it possible to check if my web page containing radcontrols are viewed in a handheld device such as IPAD, smartphones? If its a handheld device, I want to show the user a page optimized for mobile view.

Thanks
Henry

Hello,

I have enabled a customer provider and am successfully populating the tree from a database. The problem I am having is that I can't show the new folder button and the upload button is showing, but disable. How do I enable those 2 buttons?

Also when I right click on a folder, the entire menu is disabled.

THanks
Thomas
